Metropolitan Drainage Act 1935

The Act revolves around a small set of structural concepts that determine rights, liabilities and administrative mechanics.

1. Ministerial construction and maintenance powers. Sections 6 and 9 list detailed construction powers for the River Torrens and the River Sturt/Keswick/Brownhill systems respectively. The Minister may enlarge channels, construct new channels to the sea (s 6(1)(ii)), install regulators and tidal flaps (s 6(1)(iii)-(iv)), construct or reconstruct bridges (s 6(1)(v)), embankments and bed cleansing (s 6(1)(vi)), and any connected works (s 6(1)(vii)). Parallel powers exist under s 9 for the other river system, including concrete lining (s 9(1)(iii)) and alteration by embankment or otherwise (s 9(1)(iv)). These enumerated powers are expansive in physical works but are subject to procedural checks such as the independent external engineer inquiry for certain Torrens sea-discharge channels (s 6(4)).

2. Land acquisition and disposal. The Minister may acquire land either compulsorily or by agreement in accordance with the Land Acquisition Act 1969 (s 5). Surplus land may be leased or sold by the Minister and sale proceeds are to be credited against the loan moneys for the relevant Part (s 17(1)-(3)). The Act ties compensation and disputes to the Land Acquisition Act framework: where the Minister cannot agree compensation, the matter is to be dealt with as a disputed claim under s 23 of the Land Acquisition Act 1969 (s 14(2)).

3. Apportionment of cost among councils. The Act fixes the split of interest and maintenance liabilities among specified councils by percentages set out in Schedules 1 and 2 (s 7(2)-(3); s 8(2)-(3); s 10(2)-(3); s 11(2)-(3)). These schedules specify two parts each, reflecting different groupings of councils for particular elements of the works. The Minister can initiate inquiries to reassess the percentages after ten years from completion and, following a recommendation and parliamentary resolutions in both Houses, the schedules can be varied (s 18(1)-(5)). The Act requires that percentages in a part sum to 100 per cent (s 18(2)).

4. Financial mechanics and the Metropolitan Drainage Maintenance Fund. Construction is to be funded out of loan moneys provided by Parliament and any Commonwealth grant (s 6(1); s 9(1)). The Treasurer must publish in the Gazette the loan moneys expended (s 7(1); s 10(1)) and the total moneys expended including grants (s 8(1); s 11(1)); those publications set the baseline for council liabilities. Maintenance payments are paid into the Metropolitan Drainage Maintenance Fund (s 8(5); s 11(5)) which the Treasurer then pays to the Minister, without further appropriation, for authorised maintenance (s 8(5)). The Treasurer may advance monies pending loan raising and such advances are deemed loan moneys for the purpose of the Act (s 27(1)-(2)).

5. Triggers, timing and duration of liabilities. Gazette publication is the trigger event for both interest and maintenance liabilities (s 7(1); s 8(1); s 10(1); s 11(1)). Payments are due on the first day of May in the financial year next after the year of publication and then annually (s 7(4); s 8(4); s 10(4); s 11(4)). Interest liabilities are time‑limited (58 years) (s 7(4); s 10(4)). No similar time limit is specified for maintenance payments; they are payable annually as long as the Act’s mechanics remain engaged (s 8(4); s 11(4)).

6. Delegation, procurement and remedies. The Minister may delegate powers and confer the Minister’s immunities on delegates (s 16(1)-(4)). Tenders may be called for (s 12(1)); the Minister may reject tenders or, if necessary, construct the works personally (s 12(2)). The Treasurer has enforcement remedies for non‑payment by councils, including court action and, on the Governor’s direction, retention of Crown payments to a council to satisfy the debt (s 21(1)-(2)).

7. Limited compensation and immunities. Compensation is payable for damage occasioned by exercise of powers (s 14(1)) but is limited in particular respects: no compensation for materials dug from beds or banks of the listed waterways (s 14(3)); no compensation for mere entry unless damage results (s 14(4)). The Minister is immune from claims arising out of escape of waters (s 25).

These concepts together create a statutory design where the State raises loan moneys for capital drainage works, shifts some long‑term financing burden to municipal councils according to fixed apportionments, establishes a maintenance fund, and gives the Minister broad execution and land powers while constraining certain procedural and compensation aspects.

The Act identifies a narrow set of institutional and private actors with legal obligations or rights.

• The Minister. The Minister of Works, or any Minister acting for that office, is the statutory actor authorised to carry out and maintain the works (s 3 definition of Minister; s 6(1); s 9(1)). The Minister decides on works, calls tenders or proceeds to direct construction, delegates powers (s 12; s 16) and may sell or lease surplus land (s 17).

• The Treasurer. The Treasurer is the administrative payer and account keeper. The Treasurer publishes the loan and total expenditure statements in the Gazette that trigger councils’ liabilities (s 7(1); s 8(1); s 10(1); s 11(1)), pays maintenance monies to the Minister from the Metropolitan Drainage Maintenance Fund without further appropriation (s 8(5)), may advance funds pending loan raising (s 27(1)), and may sue for unpaid sums (s 21(1)). The Treasurer also must retain and apply sums advanced when appropriate (s 27(2)).

• Councils named in Schedules 1 and 2. The municipal councils listed in the two Schedules are explicitly liable for specified shares of interest and maintenance costs. Schedule 1 and Schedule 2 each provide two Parts with percentage apportionments of the liabilities. Examples include: Municipal Council of Adelaide 27 per cent in Schedule 1 Part 1 (schedules); West Torrens appears with large shares in several parts, including 33 per cent in Schedule 1 Part 2 and 75 per cent in Schedule 2 Part 2; Municipal Council of Unley 33 per cent in Schedule 2 Part 1. These councils must pay interest and maintenance on the dates set out (s 7, s 8, s 10, s 11). Councils are expressly permitted to fund payments from general revenues or by levying a special rate under the Local Government Act 1934, without ratepayer consent (s 20(2)).

• The Municipal Tramways Trust. The Trust must pay $500 annually into the Metropolitan Drainage Maintenance Fund on the first day of May after completion of the works (s 19(1)-(2)). That liability ends when it ceases to operate services between Torrensville and Henley Beach, and in that event the $250 deduction from Part 2 maintenance payments ceases to apply (s 19(3)).

• Landowners and occupiers whose land is entered upon or acquired. The Minister may enter land for survey and works (s 13), acquire land under the Land Acquisition Act 1969 (s 5), and the Act contains compensation rules for damage (s 14). Persons who suffer damage by exercise of powers are entitled to compensation subject to exceptions and dispute resolution through the Land Acquisition Act mechanisms (s 14(1)-(4)).

• Contractors and tenderers. The Minister may call tenders and accept or reject them (s 12(1)). If a contractor fails to proceed or to complete, the Minister may himself construct or complete the works (s 12(2)).

• Members of the public who use or live near affected waterways. The Act gives the Minister power to stop up or divert roads, remove or strengthen bridges, impound or divert watercourses and place materials on land for embankments or works (s 13). Those actions may affect access, property, and use of adjacent land, subject to compensation limits (s 13; s 14).

• The Governor and Parliament. The Governor is empowered to direct payment retention from Crown payments to a council to satisfy unpaid sums (s 21(2)). Parliament has a role in approving variation recommendations to the schedule percentages by passing resolutions in both Houses (s 18(3)-(5)). The Minister must not proceed with certain seaward discharge works if an independent engineer reports against the design unless Parliament otherwise decides (s 6(4)).

• Persons who obstruct or damage works. Individuals who wilfully obstruct survey or construction, remove stakes, place obstructions in cleaned or constructed beds, destroy the works or cause obstructions, face offences and penalties under s 22.

Collectively, the Act imposes long‑term financial obligations on municipal councils named in the Schedules, directs administrative power to the Minister and Treasurer, relates to landowners’ compensation rights governed by the Land Acquisition Act 1969, and affects contractors and local infrastructure users through construction powers.

Statutory duties and rights under the Act are allocated among the Minister, the Treasurer, councils, the Municipal Tramways Trust and affected private parties. Below are the principal duties and rights with section references.

Duties and decision powers of the Minister

• Conduct works. The Minister may construct, extend, cleanse and maintain works under s 6(1) and s 9(1). The Minister may alter plans as necessary (s 6(2); s 9(2)).
• Appoint external engineers for specific Torrens sea discharge channels and, in the event of an adverse report, not proceed without Parliament’s approval (s 6(4)). This is a procedural constraint on certain works.
• Call tenders and accept or reject them (s 12(1)). If no tender is accepted or a contractor defaults, the Minister may construct or complete the works (s 12(2)).
• Enter, take possession of and work upon land, set out levels, dig and remove materials and place spoil as necessary for construction and maintenance (s 13(I)-(VII)).
• Delegate functions to other persons, with delegates enjoying the same powers and immunities as the Minister (s 16(1)-(4)).
• Lease or sell surplus land and credit proceeds against the relevant loan moneys (s 17(1)-(3)).

Duties of the Treasurer and financial triggers

• Publish the statement of loan moneys expended on completion of works for each Part, which triggers council liability for interest (s 7(1); s 10(1)).
• Publish the statement of total moneys expended (including grants) for each Part, which triggers council liability for maintenance contributions (s 8(1); s 11(1)).
• Receive council payments and pay maintenance sums into and out of the Metropolitan Drainage Maintenance Fund without further appropriation (s 8(5); s 11(5)).
• Advance funds pending loan raising, with those advances treated as loan moneys for the purposes of the Act (s 27(1)-(2)).
• Enforce payment against councils by court action (s 21(1)) and apply Governor‑directed retention of Crown payments to councils to satisfy unpaid sums (s 21(2)).

Councils’ duties and financial obligations

• Pay interest at 4.5 per cent on one third of the loan moneys expended, apportioned by schedule percentages and payable annually on 1 May in the financial year next following Gazette publication and thereafter annually for 58 years (s 7(2)-(4); s 10(2)-(4)).
• Pay maintenance amounts annually equal to one half of one per cent of the total cost (less a $250 deduction for Part 2 computations), apportioned by schedule percentages and payable annually on 1 May from the financial year next after Gazette publication (s 8(2)-(5); s 11(2)-(5)).
• Make payments from general revenue or by levying a special rate under the Local Government Act 1934 without the need for ratepayer consent; the rate can be confined to part of the council area with the Minister’s written consent (s 20(1)-(2)).
• Comply with notices from the Minister to exercise powers under s 643 of the Local Government Act 1934 to clear creeks, or face offences and penalties (s 26(1)-(2)).

Rights and remedies of landowners and claimants

• Compensation for damage suffered as a result of exercise of the Minister’s powers, subject to the Act’s exceptions (s 14(1)). Where agreement on compensation is not reached, disputes are to be determined as disputed claims under s 23 of the Land Acquisition Act 1969 (s 14(2)).
• Limitations on compensation: no compensation for materials obtained from beds or banks of the named waterways (s 14(3)); no compensation for mere entry unless damage results and then it is limited to the damage caused (s 14(4)).

Other statutory rights and obligations

• Municipal Tramways Trust to pay $500 annually into the maintenance fund, subject to cessation rules tied to service operation between Torrensville and Henley Beach (s 19(1)-(3)).
• Persons must not wilfully obstruct survey or construction, pull up stakes, place obstructions or dig holes in the cleaned or constructed beds, destroy the works or permit obstructions; contravention is an offence attracting a penalty not exceeding $100 (s 22).
• The Governor may make regulations for worker conduct, protection of works from trespass and pollution and any other purpose necessary or convenient for carrying the Act into effect; regulations may prescribe penalties up to $20 (s 23(1)-(2)).
• All offences under the Act are to be disposed of summarily (s 24).

Administrative and procedural constraints

• The Minister’s power to proceed with certain seaward discharge works is constrained by an independent external engineering inquiry requirement for design adequacy and prevention of sea influx likely to injure adjacent properties (s 6(4)).
• Changes to schedule percentages require an inquiry after ten years and a recommendation approved by resolution of both Houses of Parliament, with specified timing rules about sessional passage (s 18(1)-(5)).

These duties and rights frame a system where the Minister is empowered to build and maintain river and creek drainage infrastructure, the Treasurer administrates financing and triggers liabilities, specified councils and the Municipal Tramways Trust bear apportioned financial obligations, and landowners have controlled compensation routes subject to statutory exceptions.

The Act establishes specific criminal and civil enforcement mechanisms and financial enforcement levers. The principal enforcement mechanisms, and their operational consequences, are as follows.

Summary disposal of offences

• All offences under the Act are to be disposed of summarily (s 24). That procedural rule channels prosecutions into summary jurisdictions and short timelines for prosecution, which affects evidential strategy and potential penalties.

Specific criminal offences and penalties

• The Act prescribes offences for wilful obstruction or interference with works or survey lines (s 22). The listed acts that constitute an offence include obstructing persons acting under the Minister’s authority in setting out works, pulling up poles or stakes, placing obstructions or digging holes in cleaned/constructed beds without the Minister’s written consent, destroying or injuring works, or causing or permitting obstructions affecting works (s 22(a)-(e)). The maximum penalty for offences under s 22 is a fine not exceeding one hundred dollars.

Regulatory penalty limits

• The Governor may make regulations for staff conduct and protection of the works (s 23(1)), and any such regulations may fix penalties not exceeding twenty dollars for breaches (s 23(2)). These amounts are fixed in statute and are modest in absolute terms.

Financial enforcement against councils

• Civil recovery: The Treasurer may recover sums payable under the Act from a council or from the Municipal Tramways Trust by action in any court of competent jurisdiction (s 21(1)). That provision gives the Treasurer a standard debt‑recovery route.
• Crown retention power: If a sum due by a council is not paid on its due day, the Governor may direct that the amount, or part of it, be retained and paid to the Treasurer out of any other moneys payable by the Crown or any Minister to the council; the Crown payments will be retained and applied accordingly (s 21(2)). This mechanism allows the Crown to apply other Crown disbursements to satisfy unpaid liabilities, creating a direct enforcement lever without litigation.

Compensation dispute resolution mechanisms

• Where the Minister cannot agree compensation with an owner, the amount is to be determined and the case dealt with as if it were a disputed claim within the meaning of s 23 of the Land Acquisition Act 1969 (s 14(2)). This invokes the Land Acquisition Act’s adjudicative procedures and limits recourse to general civil claims for compensation outside that framework.

Immunities and limits on claims

• The Minister is explicitly protected from claims arising out of escape of waters from rivers, pools, streams, watercourses, reservoirs or channels (s 25). This clause bars claims “arising out of or in respect of the escape of any waters” against the Minister. It narrows the avenues for civil claims for flood escape related losses.
• Delegates enjoy the same immunities from personal liability as the Minister would have if the delegate acted (s 16(4)). That allocation protects staff and delegates operationally.

Practical enforcement considerations

• Payment deadlines are keyed to Gazette publication dates. The Treasurer must publish statements showing expenditure: for interest liabilities this is the loan money statement (s 7(1); s 10(1)); for maintenance it is the total moneys expended statement (s 8(1); s 11(1)). Payments are due on 1 May in the financial year next after the financial year in which the Gazette notice is published and thereafter annually (s 7(4); s 8(4); s 10(4); s 11(4)). Non‑payment after those dates exposes councils to debt recovery and the Governor’s Crown retention direction (s 21).

Limits and ceilings

• The statutory penalties for obstruction and regulation breaches are modest and capped (s 22; s 23(2)). The Act does not create imprisonment as a sentencing option; penalties are monetary and designed for summary disposal.

Taken together, the enforcement regime mixes modest criminal penalties for physical interference, a structured compensation dispute resolution tied into the Land Acquisition Act, and robust fiscal enforcement options for the Treasurer against councils, including court recovery and Crown payment retention. The immunity for the Minister under s 25 materially restricts civil exposure for events tied to escape of waters.

The Act expressly references and integrates with several legislative instruments and established administrative procedures. The key statutory interactions are explicit in the text.

Land Acquisition Act 1969

• The Minister’s power to acquire land is expressly made subject to and in accordance with the Land Acquisition Act 1969 (s 5). Compensation where the Minister cannot agree with an owner is to be dealt with as if it were a disputed claim within the meaning of s 23 of the Land Acquisition Act 1969 (s 14(2)). Thus acquisition, valuation and dispute processes defer to the Land Acquisition Act regime, drawing on its adjudication and compensation machinery.

Local Government Act 1934

• Councils may raise special rates under the Local Government Act 1934 for the purpose of meeting payments under this Act, and explicit authorisation is given for such special rates to be declared and levied without the consent of ratepayers (s 20(2)). The Act further provides that, with the Minister’s written consent, a special rate may be declared on ratable property within part only of the council area (s 20(2)). Section 26(1) permits the Minister to require a council to exercise powers conferred upon councils by s 643 of the Local Government Act 1934 to have creeks cleared; failure to comply triggers an offence (s 26(2)). These cross‑references draw municipal authorities and rating rules into the Act’s finance and operational mechanics.

Gazette publication and parliamentary procedure

• The Treasurer’s publication in the Gazette of loan and total expenditure statements is the statutory trigger for council liabilities (s 7(1); s 8(1); s 10(1); s 11(1)). The Act also requires that recommendations to alter schedule percentages be laid before both Houses of Parliament and approved by resolution of both Houses, with rules about sessional timing (s 18(3)-(5)). Those requirements embed administrative acts in parliamentary processes and public notice regimes.

Statute Law Revision and publication acts

• The legislative history records that some provisions, such as a former s 2, have been omitted under the Legislation Revision and Publication Act 2002. The Act’s legislative history in the source shows entries for Statute Law Revision Acts (1935, 1974) and notes the s 2 omission (legislative history section). That indicates the Act’s text has been subject to formal revision and re‑publication processes which affect interpretation only to the extent of removed provisions.

Interplay with Crown payment and administrative law

• The Governor’s power to direct retention of sums otherwise payable by the Crown to a council to satisfy unpaid amounts (s 21(2)) intersects with Crown finance and administrative arrangements. The Treasurer’s ability to advance funds pending loan raising, with those advances treated as loan moneys for the Act’s purposes (s 27(1)-(2)), interacts with loan raising and appropriation mechanics.

Regulations and summary proceedings

• The Governor may make regulations for worker conduct and protection of works (s 23(1)). Any such regulations may fix penalties up to $20 (s 23(2)). The requirement that all offences be dealt with summarily (s 24) interacts with criminal procedure rules and limits prosecutorial discretion to summary jurisdictions.

Municipal Tramways Trust and operational cessation

• The Municipal Tramways Trust’s $500 annual contribution into the maintenance fund is tied to its operation of transport services between Torrensville and Henley Beach. The liability ceases if the Trust ceases to operate such services, and that cessation also affects the $250 deduction in Part 2 maintenance computations (s 19(1)-(3)). That provision links transport operation status to the Act’s financial mechanics.

Overall, the Act deliberately embeds its major operational and financial pathways into existing legislative frameworks. Acquisition, compensation and dispute mechanisms are channelled into the Land Acquisition Act 1969. Municipal financing follows local government rating law and allows compulsory special rates without ratepayer consent. Parliamentary resolution requirements apply to percentage variations, and Gazette publication is the formal trigger for liability. These touchpoints concentrate implementation risk in administrative processes such as accurate publication, adherence to Land Acquisition Act procedures, and timely exercise of Local Government Act special rating powers.

The source provides a legislative history that records enactment and subsequent statute law revision entries. The entries in the source are the authoritative record of amendments and notable editorial changes.

Principal Act and early amendments

• The Metropolitan Drainage Act 1935 was enacted in 1935, receiving assent and commencing on 14 March 1935 (Legislative history table). The source lists the original Act and indicates Statute Law Revision Acts with which the Act interacted in 1935 (Statute Law Revision Act 1935, No 2246, assent 19 December 1935, commenced 19 December 1935).

Later revision

• A further revision entry appears for the Statute Law Revision Act (No. 2) 1974 (No 84), with assent on 21 November 1974 and commencement of Schedule 2 on that date. The legislative history indicates that entries that relate to provisions deleted appear in italics and new entries appear in bold, as per the source’s note.

Provisions amended or omitted

• The source includes a note under “Provisions amended since 3 February 1976” which records that s 2 was omitted under the Legislation Revision and Publication Act 2002. The Act as reproduced in the source shows no s 2, consistent with the revision. The legislative history section notes other formal revision actions but does not show substantive policy amendments beyond the listed revisions.

No other post‑1974 amendments recorded in the provided source

• The legislative history supplied in the source does not list other amending Acts after 1974 within the excerpt. The “Notes” in the legislative history point the reader to the Index of South Australian Statutes or the online legislation repository for further information on subsidiary legislation and any subsequent changes. The source’s summary indicates that entries appear in bold for new amendments, and that provisions deleted appear in italics, but the only explicit statutory omission identified in the source text is s 2 removed under the Legislation Revision and Publication Act 2002.

Implication for interpretation

• The Act retains its original structure with Parts 1-4 and the Schedules visible in the source. Where the Act references current legislation, such as the Land Acquisition Act 1969 and the Local Government Act 1934, those cross‑references must be interpreted in the context of any later amendments to those statutes. The source does not supply consolidated amendments to those other Acts.

For authoritative, up‑to‑date amendment history and any subordinate legislation made under the Act, the source directs users to the Index of South Australian Statutes or the official South Australian legislation website (as noted under “Notes” in the legislative history). The legislative history in the source is limited to the items displayed and records the statutory lifespan from enactment in 1935, through Statute Law Revision Acts and the reported omission of s 2 under the Legislation Revision and Publication Act 2002.

The text of the Act supplied in the source does not record any case law, reported decisions or litigation outcomes. There are no cases named in the Act itself, and the legislative history and notes do not list judicial decisions construing the Act. Where litigation pathways are embedded in the Act, they are procedural or referential rather than judicially decided matters included in the source:

• Compensation disputes. The Act expressly adopts the Land Acquisition Act 1969’s machinery for disputed compensation claims where the Minister and claimant cannot agree (s 14(2)). Any litigation or adjudication would thus proceed under the Land Acquisition Act framework rather than under a separate new litigation regime created by this Act. The source does not supply any decisions under that framework.

• Summary offences. The Act requires summary disposal of offences (s 24), which directs criminal proceedings into summary jurisdictions. The source does not reference any prosecutions or outcomes.

• Recovery of unpaid sums. The Treasurer has civil remedies by action in any court of competent jurisdiction for recovery of sums payable by councils or the Municipal Tramways Trust (s 21(1)). Again, the source contains no record of such actions having been commenced or determined.

• Parliamentary variation procedure. The Act prescribes a process for varying schedule percentages that requires recommendations and resolutions of both Houses of Parliament (s 18(2)-(5)). The source does not indicate that any such variations have occurred.

Because the source contains no case references, readers seeking litigation history or judicial interpretation should consult court databases, law reports, and administrative tribunal records for decisions referring to the Metropolitan Drainage Act 1935. The Act’s text points to dispute resolution mechanisms via the Land Acquisition Act 1969 and provides enforcement and recovery routes (s 14(2); s 21), so potential litigation would most likely arise under those provisions or in relation to summary offence prosecutions or civil recovery actions. The absence of case citations in the text requires external legal research to identify any authoritative judicial treatment.

The Act’s drafting and mechanics contain multiple features that can produce practical or legal pitfalls if overlooked. These are concrete textual traps and operational points flagged by the Act itself.

Timing and Gazette publication as the trigger

• Council liabilities (interest and maintenance) are not payable until the Treasurer publishes the relevant statement in the Gazette (s 7(1); s 8(1); s 10(1); s 11(1)). Payments are due on the first day of May in the financial year next after the financial year in which the Gazette statement is published and thereafter annually (s 7(4); s 8(4); s 10(4); s 11(4)). Practically this means councils should not assume immediate liability upon construction completion; reliance on the Gazette notice date is crucial. Administrative errors or delays in publication will alter the payable year and potentially dispute the timing of liabilities.

Long interest duration but finite

• Interest payable by councils is fixed at 4.5 per cent on one‑third of the loan amount and is payable annually for fifty‑eight years from the first payable year (s 7(2)-(4); s 10(2)-(4)). This creates a long tail of interest obligations that councils must budget for, although it is time‑bounded. Councils facing legacy liabilities must plan for multi‑decadal burden even if capital loans are repaid earlier.

Maintenance liability potentially indefinite

• By contrast, maintenance contributions are expressed as annually payable amounts with no statutory termination date within the Act: one half of one per cent of the total amount is payable annually (s 8(2); s 11(2)). The Act does not provide a definitive expiry for maintenance liabilities equivalent to the 58‑year cap on interest. Councils and other contributors should be aware of the possibly continuing obligation unless legislative or administrative steps change the fund or repeal provisions.

Different computations and a $250 deduction for Part 2

• The maintenance formula for works under Part 2 (River Torrens) is one half of one per cent of the total amount less a deduction of $250 (s 8(2)-(3)). Part 3’s maintenance provisions do not carry that deduction (s 11(2)-(3)). Moreover, s 19(3) ties the $250 deduction to the Municipal Tramways Trust’s ongoing operation of a service; if that service ceases, the deduction ceases to apply. Small numeric drafting differences like this can materially affect apportionment totals and should be checked when calculating contributions.

Concentration of burden in schedules

• The Schedules allocate percentages that can concentrate liability in a small number of councils. For example, Schedule 2 Part 2 assigns West Torrens 75 per cent and Marion 20 per cent, with Glenelg 5 per cent. Those allocations are statutorily binding until changed by the Act’s variation procedure (s 18). Councils carrying large shares may face substantial fiscal pressure. The Act permits inquiries and parliamentary changes, but the process has timing constraints and requires parliamentary resolution (s 18(1)-(5)).

Special rates without ratepayer consent

• Councils may levy a special rate under the Local Government Act 1934 to meet payments without requiring ratepayer consent (s 20(2)). The absence of a requirement for consent reduces democratic recourse at the local level and places the onus on councils to set rates administratively. If a council’s budget is tight, the lack of a requirement for a ratepayer vote could be politically sensitive.

Ministerial immunity for escape of waters

• Section 25 purports to bar all claims or actions against the Minister arising out of the escape of any waters from rivers, pools, streams, watercourses, reservoirs or channels. That immunity narrows recovery options for parties suffering damage from water escape events linked to the works. Claimants may therefore be limited to compensation under the Land Acquisition Act for damage from authorised activity, and common law remedies for water escape may be curtailed in respect of the Minister.

Compulsory acquisition and narrow compensation exceptions

• The Minister’s power to acquire land is subject to the Land Acquisition Act 1969 (s 5), but s 14(3) excludes compensation for earth, stone, minerals, trees or other things dug or obtained from river beds or banks. Section 14(4) restricts compensation for mere entry unless damage results. These exceptions narrow recoverable items; affected landowners should not assume full recompense for all losses connected to resource removal from beds or banks.

Parliamentary process for schedule variation

• The procedure to vary percentages requires an inquiry, recommendations and resolutions in both Houses of Parliament. The Act prescribes minimum timing, including a ten‑year wait before the first inquiry and five‑year intervals thereafter, and constraints on sessional passage of resolutions (s 18(1)-(5)). This creates a slow, politically mediated path to re‑apportionment. Councils seeking relief face procedural inertia.

Delegation with immunities

• Delegates exercise ministerial powers and enjoy immunities akin to the Minister (s 16(1)-(4)). While delegation aids administration, it can concentrate discretion outside direct ministerial accountability and complicate questions of personal liability for officers.

Limited criminal penalties and summary direction

• Criminal penalties are modest, with obstruction punishable by up to $100 and regulation fines up to $20 (s 22; s 23(2)). The Act directs that all offences be dealt with summarily (s 24). These features will influence prosecutorial and enforcement choices, including whether civil remedies and fiscal enforcement are preferable to criminal prosecution.

Treasurer’s advance treated as loan money

• The Treasurer may advance sums pending loan raising and such sums are deemed loan moneys for the purposes of interest and apportionment computations (s 27(1)-(2)). That facility can be used to start works before loan raising is complete, but it also means councils’ liabilities may be triggered by advances rather than formal loan issues.

Taken together these points are practical traps that require attention to publication timelines, arithmetic differences between Parts, long durations of liability for interest, concentrated apportionments, and limited civil remedies against the State.

This section sets out practical, text‑based compliance steps for the Minister, the Treasurer, councils, the Municipal Tramways Trust, landowners and contractors so they can operate within the Act’s mechanics.

For the Minister and departmental officials

• Follow the external engineering inquiry requirement under s 6(4) before proceeding with construction of any channel authorised to discharge the River Torrens into the sea. Appoint qualified engineers practising outside the State, obtain their report and, if adverse, do not proceed unless Parliament otherwise decides. Document the appointment and the report and ensure a record of any Parliamentary decision is placed on the public record.
• If constructing works, comply with powers and constraints in s 6 and s 9, including design, regulation, embankments, cleansing and bridge works. Use s 12 to run tenders if contractors are to be engaged, but be aware the Minister may self‑construct if necessary (s 12(2)). Maintain procurement records, tender evaluations and contract documents.
• If acquiring land, follow the Land Acquisition Act 1969 procedures as required by s 5. Ensure notices, valuations and offers comply with the Land Acquisition Act and that disputed compensation is managed under s 23 of that Act as required by s 14(2).
• If selling or leasing surplus land, follow s 17: record disposals, pay proceeds to the Treasurer, and ensure credits are correctly applied against the loan moneys for the relevant Part.

For the Treasurer and finance officers

• Publish the required Gazette statements precisely as required. For interest liabilities publish the loan moneys statement upon completion of the works (s 7(1); s 10(1)). For maintenance liabilities publish the total expenditure statement including Commonwealth grants (s 8(1); s 11(1)). Maintain timely and accurate records to avoid disputes about the trigger date for liabilities.
• Apply collections to the Metropolitan Drainage Maintenance Fund and pay amounts requested by the Minister from that fund without further appropriation (s 8(5); s 11(5)). Record debits and credits carefully and provide councils with notification of amounts payable and the percentages applied from the schedules.
• Use s 27(1) prudently if advancing funds pending loan raising, keeping records showing that advances are treated as loan moneys and ensuring repayment or application when loans are raised (s 27(2)).

For councils named in Schedules 1 and 2

• Monitor the Gazette for the Treasurer’s publication that triggers payment obligations. Payments for interest and maintenance become due on the first day of May in the financial year next after publication and annually thereafter (s 7(4); s 8(4); s 10(4); s 11(4)). Missing those dates risks exposure to civil recovery and the Governor’s retention direction (s 21(1)-(2)).
• Budget for the interest payment, calculated at 4.5 per cent on one third of the loan moneys expended and apportioned by the schedule percentages shown opposite the council names (s 7(2)-(3)). Ensure accounting systems can recognise the 58‑year duration of interest liability (s 7(4); s 10(4)).
• Budget for maintenance payments at 0.5 per cent annually on the total amount expended for the relevant Part and apportioned by the schedule percentages (s 8(2)-(3); s 11(2)-(3)). Note the deduction of $250 applicable to the Part 2 calculation (s 8(2)-(3)) and the Municipal Tramways Trust condition under s 19(3).
• If needed, levy a special rate under the Local Government Act 1934 to fund payments; the Act authorises special rates without ratepayer consent and allows such rates to be confined to part of the council area with the Minister’s written consent (s 20(2)). Ensure compliance with Local Government Act 1934 requirements for declaration, levying and recovery of rates.
• Respond to any written requisition by the Minister under s 26(1) to exercise powers under s 643 of the Local Government Act 1934 to have creeks cleared. Failure to comply within two months produces an offence with penalty up to $100 (s 26(2) and s 22).

For the Municipal Tramways Trust

• Pay $500 into the Metropolitan Drainage Maintenance Fund annually on 1 May after completion of the works (s 19(1)-(2)). Monitor the continued operation of the Torrensville-Henley Beach service because cessation affects liability and the $250 deduction in Part 2 calculations (s 19(3)).

For landowners and occupiers

• If the Minister seeks to enter land for survey or works, know that entry powers are broad under s 13. Claims for compensation are available under s 14(1) but limited in important ways: no compensation for materials obtained from beds or banks (s 14(3)); no compensation for mere entry unless damage results (s 14(4)). If compensation is disputed, pursue remedies under the Land Acquisition Act’s disputed claim process referenced in s 14(2).
• If affected owners anticipate damage from works, prepare detailed evidence connecting damage to specific ministerial acts to support compensation claims processed under the Land Acquisition Act.

For contractors and tenderers

• If responding to a tender under s 12(1), expect the Minister may reject tenders and to be subject to contract conditions the Minister deems advisable. If awarded a contract, performance is necessary because the Minister may complete the works himself if a contractor fails to begin or complete work in accordance with the contract (s 12(2)). Keep performance security and contractual claims well documented.

General compliance and administrative steps

• Maintain contemporaneous records of Gazette publications, invoices, payment receipts, maintenance fund allocations and any ministerial notices such as creek clearing or special rates approval.
• When seeking to vary schedule percentages, follow the Act’s timing requirements: no inquiry until ten years after completion for the first inquiry, five years between inquiries thereafter, and parliamentary resolutions in both Houses as prescribed (s 18(1)-(5)). Plan for long lead times.
• Be aware of the Minister’s immunity for water escape claims under s 25. Parties considering claims for water damage should first evaluate whether statutory compensation via the Land Acquisition Act is available.

Following these procedural and accounting steps will place responsible persons in the position required by the Act. In all cases, the Act’s text references other statutes for acquisition, rating and compensation procedures, so concurrent compliance with those statutes is necessary to avoid procedural challenges.
