Christmas Island Utilities and Services (Water, Sewerage and Building Application Services Fees) Determination 2016

The instrument’s main operational concepts are (1) land categorisation, (2) fee types and schedules, (3) billing and notice rules, (4) enforcement by restriction, (5) concessions and special arrangements, and (6) Administrator discretion to vary fees.

1. Land categorisation (s 5; s 4 definitions)

• The Determination defines multiple mutually exclusive categories: residential land, commercial/residential, commercial, industrial, vacant, government, mining, institutional/public, charitable purposes land, and local government land (s 5(1)-(11)). These categories determine which fee table or line items apply (Schedules 1-3).
• Several definitions are cross‑referenced to applied laws. For example, “dwelling” and “area associated with a dwelling” are taken from the Water Services Act 2012 (WA) (CI) (s 4), “gross rental value” is taken from the Valuation of Land Act 1978 (WA) (CI) (s 4), and “eligible pensioner/eligible senior” are taken from the Rates and Charges (Rebates and Deferments) Act 1992 (WA) (CI) (s 4).

2. Fee types and schedules (s 6(3)-(3)(e); Schedules 1-5)

• Fixed fees are annual charges by land category and, for commercial/industrial, by meter size (Schedule 1 for water; Schedule 2 for sewerage). Sewerage fixed fees for residential land are a rate in the dollar of GRV with minimum and maximum annual fees (Schedule 2 cl 1).
• Quantity fees are per-kilolitre charges in bands (Schedule 3), and include special higher rates for high-volume residential consumption (banding up to >750 kL at $10.432 per kL), and elevated rates for commercial/residential above thresholds and for non-residential categories (Schedule 3 cl 1).
• Other services (Schedule 4) contain quoted-cost items and fixed fees for activations, meter readings, meter tests and restoration after restriction (Schedule 4 items 3, 5, 7, 8).
• Building-application fees for matters under s 82 of the Water Services Act (WA) (CI) are in Schedule 5.

3. Billing and notice rules (s 6(5)-(8); s 8)

• Fees must be charged by sending a notice to the owner or occupier to which the service is supplied or related (s 6(5)). The notice must specify amount and payment day (s 6(6)), and must allow at least 16 days from the day notice is sent to the due day (s 6(7)). Fees are payable to the Administrator on behalf of the Commonwealth, and the owner or occupier is liable once notice is sent (s 6(8)).

4. Enforcement by supply restriction (s 9)

• The Determination provides a staged debt-handling process culminating in the Administrator’s ability to restrict supply if an outstanding fee is not brought up to date and no special payment arrangement is in force: reminder (10 days to pay) then notice to restrict (period not less than 7 days) then supply restriction until fee and any restoration fee are paid or a special payment arrangement is entered (s 9(1)-(6)). The Administrator must send the reminder (s 9(2)).

5. Concessions and hardship (s 7; s 10)

• Eligible pensioners and eligible seniors can receive reductions: pensioner rate is a 50% reduction of fees mentioned in Schedules 1-3 (subject to eligibility rules in s 7); senior rate is 25% off fixed fees in Schedules 1-2 (s 7(4) definitions). The pensioner quantity concession for up to 600 kL requires the pensioner to be the occupier of residential land (s 7(2)).
• The Administrator may agree a special payment arrangement in writing if an owner/occupier notifies difficulties; while such an arrangement is in force, the fee is due under that arrangement (s 10).

6. Administrator discretion to vary (s 6(3A), (4), (4A), (4B) and Schedule 3 cl 3)

• The Administrator may agree, in writing, to lower fixed or quantity fees for particular land, including agreement to a nil amount (s 6(3A), (4), (4A)). The Administrator may publish such agreements on the Department’s website (s 6(4B)). For discharge to sewer calculations, the default discharge factor is 95% but the Administrator may agree a lower percentage in writing (Schedule 3 cl 3).

Those are the core legal and operational constructs the Determination creates. The instrument couples a tariff schedule with administrative processes that vest final billing and many exceptions in the hands of the Administrator.

Primary affected parties are owners and occupiers of land on Christmas Island, the Administrator (as biller and enforcer), the Commonwealth (as ultimate recipient of fees), and contractors engaged to perform quoted-cost services.

• Owners and occupiers (s 6(5)-(8)). The instrument makes the person to whom the service is supplied, or in relation to which the service is supplied, the recipient of the notice (s 6(5)). Once the Administrator sends the notice, the owner or occupier is liable to pay and the fee is payable to the Administrator on behalf of the Commonwealth (s 6(8)). The distinction matters because, for example, fixed fees in Schedules 1 and 2 apply by land category and are charged to the owner or occupier as appropriate.

• Eligible pensioners and eligible seniors (s 7). The Determination explicitly affects persons who qualify under the Rates and Charges (Rebates and Deferments) Act 1992 (WA) (CI) definitions, by giving them reduced rates: pensioner rate is 50% off Schedules 1-3 (with quantity limit for pensioners) and senior rate is 25% off fixed fees in Schedules 1-2 (s 7(4)).

• Businesses and commercial users. Commercial land, commercial/residential land, industrial, mining, shipping and strata-titled commercial properties are separately categorised and face different fixed and quantity charges (Schedules 1-3). High-volume commercial users and shipping customers face substantially higher per-kL charges or fixed fees depending on meter size and discharge allowances (see Schedule 3 item 6 and Schedule 1 item 2).

• Institutions, charities, local government and government land. Institutional/public, charitable and local government land enjoy nil fixed water fees (Schedule 1 item 3), but may face sewerage fixture fees (Schedule 2, and Schedule 1 indicates nil water fees only for item 3). Government land is separately categorised (s 5(7)) and municipal/local government land has its own line in Schedule 1 and Schedule 2, and certain fees apply to government land for fixtures (Schedule 2 item 5).

• Contractors and service providers. Several items in Schedule 4 and Schedule 5 use “quoted cost” for relocations, disconnections, installations and sewer work. Contractors engaged to perform these services supply the cost quotations that determine the fee charged to the customer (Schedule 4 cl 1 and cl 2, and Schedule 4 cl 10; Schedule 4(2) defines quoted cost).

• The Administrator (decision-maker). The Administrator determines notices, may agree fee reductions and special payment arrangements in writing, may publish agreements, must follow the reminder/notice steps prior to restriction (s 6(3A),(4),(4A),(4B); s 9; s 10). Operationally the Administrator is the actor who decides billing, enters agreements, assesses water used (Schedule 3 cl 2 references “assessed by the Authority”), and may restrict supply.

• Occupiers and owners have overlapping and particular obligations depending on property type. For example, a pensioner concession for quantity fees requires that the pensioner be the occupier of residential land for the 600 kL concession (s 7(2)(a)-(b)), while fixed-fee concessions require the pensioner or senior be both owner and occupier of residential land (s 7(1) and (3)).

Who pays and who decides are thus clearly allocated: notices are sent to owner or occupier (s 6(5)), payment liability attaches on notice (s 6(8)), and the Administrator decides and executes concessions, arrangements, notice timing and service restriction (ss 6, 9, 10 and Schedules). The Determination therefore primarily affects household consumers, commercial operators, institutional users and anyone undertaking building work tied to water/sewerage services on Christmas Island.

This instrument sets out duties and limited rights for both the Administrator and owners/occupiers. It is both a tariff schedule and a mini-procedural statute for billing, concessions and enforcement.

Administrator duties and discretions

• Charge by notice: The Administrator must charge a fee by sending a notice to the owner or occupier to which the service is supplied or relates (s 6(5)). The notice must specify the amount and the due day (s 6(6)).
• Timing requirement: The due day provided in the notice must be at least 16 days after the day the notice is sent (s 6(7)).
• Reminder and pre-restriction procedures: If a fee remains unpaid and 14 days have elapsed after the due day and no special payment arrangement exists, the Administrator must send a reminder advising that supply may be restricted if unpaid within 10 days (s 9(1)-(2)). If unpaid after that 10-day period, the Administrator may send a notice to restrict, which must state that action may be taken to restrict after not less than 7 days (s 9(3)-(5)). The Administrator may then restrict supply until payment or a special arrangement is in force (s 9(6)).
• Agreement powers: The Administrator may agree in writing to lower fixed fees or quantity fees for particular land, including agreeing nil amounts (s 6(3A), (4), (4A)). The Administrator may publish such agreements (s 6(4B)). Similarly, the Administrator may agree in writing to a lower discharge factor for a property (Schedule 3 cl 3(b)).
• Special payment arrangements: The Administrator may enter a special payment arrangement in writing if the owner/occupier notifies difficulties in paying and the Administrator agrees (s 10(1)-(2)). While such an arrangement is in force, the fee is due in accordance with the arrangement (s 10(2)).

Owner/occupier duties and rights

• Liability to pay when notice issued: Once the Administrator issues the notice under s 6(5) and subject to any special payment arrangement, the owner or occupier is liable to pay the fee as specified and within the time stated (s 6(8); s 8).
• Notice-period protections: Owners/occupiers are guaranteed a minimum of 16 days between notice and due date (s 6(7)), and the reminder and further notice steps must precede restrictions (s 9).
• Right to request special payment arrangement: An owner or occupier experiencing payment difficulties may notify the Administrator and seek a special payment arrangement; if the Administrator agrees in writing, the arrangement governs due dates (s 10).
• Concession rights: Eligible pensioners and eligible seniors are entitled to reduced fees under s 7 provided they meet the ownership/occupation conditions in that section. Pensioners may receive a 50% reduction on named items and a capped quantity concession up to 600 kL for residential occupiers (s 7(1)-(2)); eligible seniors can receive 25% reduction on fixed water and sewerage fees where they are owner-occupiers of residential land (s 7(3)).
• Right to negotiate fee reductions: Owners or occupiers may negotiate with the Administrator to obtain reduced fixed or quantity fees for particular land if the Administrator agrees in writing (s 6(3A), (4)).

Billing and service provisions

• Method of measuring and assessing use: Where quantity fees for discharge to sewer apply to commercial/government/industrial land, the number of kilolitres is worked out as “number of kilolitres assessed by the Authority as having been used by the owner or occupier of the property in the period times the property's discharge factor” (Schedule 3 cl 2 formula). The default discharge factor is 95% unless the Administrator agrees a lower percentage in writing (Schedule 3 cl 3).
• Quoted-cost items: For some installation, relocation and connection work, fees are defined as the contractor’s quoted cost (Schedule 4 cl 1, cl 2, cl 9, cl 10; Schedule 4(2) defines “quoted cost”).

Rights and constraints not present

• The Determination does not create express court enforcement provisions, interest on overdue amounts, or explicit debt-recovery mechanisms beyond supply restriction and payment of restoration fees (s 9, Schedule 4 item 8). Nor does it create appeal rights or independent review mechanisms in the text of the instrument; rights may exist under other applied laws but are not in this Determination.

In short, the Administrator bears the duty to bill and run the reminder/notice process fairly as specified, and owners/occupiers have payment and notification duties together with limited concession and negotiation rights. The Administrator’s written-agreement discretions (s 6(3A),(4),(4B); Schedule 3 cl 3) are significant because they allow bilateral adjustments to the published schedule.

The Determination does not establish criminal penalties or fines within its text. Enforcement is administrative and focused on service restriction and restoration fees. The mechanism and fees that operate as the instrument’s enforcement regime are set out primarily in s 9 and Schedule 4.

Supply restriction and restoration

• Stepwise precondition for restriction. Before the Administrator may restrict supply, the conditions of s 9 must be met: there must be unpaid fees in breach of a notice, at least 14 days must have elapsed after the specified due date and no special payment arrangement must be in force (s 9(1)). The Administrator must first send a reminder advising the owner/occupier that restriction may follow if the fee is not paid within 10 days (s 9(2)). If unpaid within those 10 days, the Administrator may send a notice to restrict that must allow not less than 7 days before restriction can occur (s 9(3)-(5)). These timing thresholds create minimum procedural protections before a restriction is implemented.
• Restriction scope and duration. If the owner/occupier does not pay within the period stated in the notice to restrict, the Administrator may restrict the supply of the service to the land until either the fee and any restoration fee is paid, or a special payment arrangement under s 10 is in force (s 9(6)(a)-(b)).
• Restoration fees. Schedule 4 item 8 sets specific restoration fees where restoration occurs: $241.90 for restoration between 7 am and 4 pm on weekdays (excluding Saturday, Sunday or public holiday) and $384.39 for other times (Schedule 4 cl 1 item 8). These restoration fees are explicitly recoverable as part of the condition for re-connecting the service following restriction (s 9(6)(a)(ii)).

Other enforcement and recovery mechanics

• The Determination is silent on interest on overdue sums, debt collection through courts, liens on property, or registered charges. It expressly makes the fee payable to the Administrator on behalf of the Commonwealth (s 6(8)(b)), but does not specify statutory debt-recovery procedures in this instrument. Other applied laws or the principal Ordinance may contain supplemental recovery powers; the Determination itself limits its enforcement mechanism to administrative restriction and restoration costing.
• For services billed on a quoted‑cost basis, the actual cost may be passed through to the owner/occupier if charged (Schedule 4 cl 1 and cl 2 and cl 9 cl 10). The determination of quoted cost depends on the contractor engaged; the Administrator does not publish a cost schedule for quoted-cost items within this instrument.

Procedural duties on the Administrator

• The Administrator has mandatory procedural duties before restricting supply (s 9(2)-(5)). Failure to follow these steps would be a departure from the instrument’s own enforcement procedure.

No criminal penalties shown

• There are no express offences or criminal penalties in this Determination for non-payment, tampering with meters, or other conduct; enforcement is limited to civil administrative measures (restriction and restoration fees). If criminal sanctions exist under other applied laws (for example, the Water Services Act 2012 (WA) (CI) or the Ordinance), they are not reflected in this Determination.

In short, enforcement is practical and service-focused: the Administrator may withhold supply to compel payment, and may charge specific restoration fees. The Determination establishes minimal procedural safeguards through notice periods and an opportunity to negotiate special payment arrangements, but leaves broader debt-recovery mechanisms and criminal sanctions to other instruments or common law.

This Determination explicitly imports definitions and cross-references other applied laws, and it sits as a tariff instrument under the Christmas Island Utilities and Services Ordinance 2016. The text identifies several interlocks.

Authority and Gazette requirement

• The instrument is made under paragraph 7(2)(a) of the Christmas Island Utilities and Services Ordinance 2016 (s 3). The instrument notes that notices charging fees must also be notified in the Gazette,see s 8 of the Christmas Island Utilities and Services Ordinance 2016 (s 6(5) note). That indicates a statutory requirement external to this Determination for public notification by Gazette.

Definitions and applied-law imports

• Water Services Act 2012 (WA) (CI): The Determination imports the meanings of “dwelling” and “area associated with a dwelling” from subsection 3(1) of the Water Services Act 2012 (WA) (CI) (s 4). Schedule 5 also refers to dealing with a notice under s 82 of the Water Services Act 2012 (WA) (CI) in the context of building application fees, so building-application procedures and any pre-requisites are controlled by that Act.
• Rates and Charges (Rebates and Deferments) Act 1992 (WA) (CI): The definitions of “eligible pensioner” and “eligible senior” are taken from that Act (s 4); pensioner and senior concessions in s 7 therefore depend on eligibility criteria set out in that separate statute.
• Valuation of Land Act 1978 (WA) (CI): “Gross rental value” is defined by this Act and is the basis for calculating the rate-in-the-dollar sewerage fixed fee for residential land in Schedule 2 (s 4; Schedule 2 cl 1(a)).
• Local Government Act 1995 (WA) (CI): The definition of “owner” in relation to land imports the meaning from section 1.4 of that Act (s 4).
• The Determination acknowledges that other fees or infrastructure contributions may be payable under an applied law such as the Water Services Act 2012 (WA) (CI) (s 6 note). That signals that this Determination does not exhaust the universe of liabilities connected to water and sewerage; developers, planners and owners must consult applied laws for infrastructure contributions or other statutory obligations.

Operational interactions and administrative functions

• Assessment by the Authority: Schedule 3 cl 2 uses “Number of kilolitres assessed by the Authority as having been used by the owner or occupier of the property in the period”. The identity, powers and methodology of “the Authority” for assessing use and meter readings are matters defined by the Water Services Act or the principal Ordinance, not by this Determination. Thus operational measurement standards, meter installation rules and appeals about assessment methodology likely fall under the Water Services Act or the Ordinance.
• Building application notices (Schedule 5). Fees for dealing with notices under s 82 of the Water Services Act 2012 (WA) (CI) tie this Determination to building approvals and plumbing/sewerage compliance regimes administered under the Water Services Act.

Litigation and review avenues (not in instrument)

• The Determination does not itself provide for merits review, judicial review or appeal rights in respect of billing decisions, fee agreements, special payment arrangements, or the Administrator’s discretions. Where such rights exist, they must be located in the parent Ordinance, the Water Services Act, or general administrative law (judicial review) principles.

In practice, therefore, the Determination forms a tariff and procedural layer that operates in concert with the substantive water and sewerage regulatory architecture set out in the Water Services Act 2012 (WA) (CI) and the Christmas Island Utilities and Services Ordinance 2016. Practitioners must consult those instruments for measurement standards, licensing, administrative decision‑making powers and any appeal routes that this Determination assumes or depends upon.

The instrument identifies itself as the Christmas Island Utilities and Services (Water, Sewerage and Building Application Services Fees) Determination 2016 (s 1). The authority for making it is paragraph 7(2)(a) of the Christmas Island Utilities and Services Ordinance 2016 (s 3). The instrument states that the fees determined apply from and including 1 July 2025 (s 6(2)), signalling a temporal application date that is later than the instrument year embedded in its title.

Within the text provided there is no schedule or note of prior amendments to this Determination. The instrument itself contains no amending provisions nor transitional clauses. The only explicit internal modification power it contains is procedural: the Administrator may agree in writing to different (lower) fees for particular land (s 6(3A), (4)), including nil (s 6(4A)), and to publish such agreements (s 6(4B)). That is an operational discretion rather than a formal amendment clause.

Absent any further material (for example, Gazette entries or registers of instruments), the observable amendment history from the instrument alone is:

• 2016: instrument created and named as the Determination 2016 (s 1).
• 1 July 2025: fees are stated to apply from and including this date (s 6(2)).

Because the instrument references external statutes and definitions (Water Services Act 2012 (WA) (CI), Valuation of Land Act 1978 (WA) (CI), Rates and Charges (Rebates and Deferments) Act 1992 (WA) (CI), Local Government Act 1995 (WA) (CI)), changes to those Acts after 2016 could alter the operation of this Determination in practice. For example, amendments to the definitions of “eligible pensioner” or to valuation methods for gross rental value would affect which persons qualify for concessions and how sewerage fees are calculated (Schedule 2 cl 1 uses GRV). Any legislative or regulatory change to the parent Ordinance (Christmas Island Utilities and Services Ordinance 2016) could also change the legal basis, the Gazette notification requirements (noted in s 6(5) note), or the Administrator’s powers.

For a full formal amendment history (including any subsequent determinations or replacement instruments, and the Gazette entries required under the Ordinance), consult the Government Gazette, the Departmental registers and the consolidated legislation database. The Determination text alone does not include a chronological amendment record beyond its year of instrument title and its stated effective date.

The instrument as supplied makes no reference to litigation, court orders, disputes, or precedent decisions. It does not cite cases, nor does it record any legal challenges, stays or declaratory judgments. The Determination is a rule-setting statutory instrument and, within its text, contains no chapter describing legal proceedings.

Absent references in the instrument, the following factual points arise from the text itself:

• There is no litigation history recorded or embedded in the Determination.
• The Determination neither creates nor documents internal appeal mechanisms for billing decisions; any judicial or administrative review rights would need to be sought under the parent Ordinance, the Water Services Act 2012 (WA) (CI), or general administrative law. The instrument is silent on remedies beyond the staged reminder/notice procedure and the ability to negotiate special payment arrangements (s 9 and s 10).
• For practitioners seeking to know whether any litigation has targeted these fees (for example, constitutional challenges, judicial review of Administrator discretion, or disputes over the meaning/application of land categories), external research in case law databases and Government Gazette records is required. The instrument does not contain that material.

If a client needs to know whether the Determination has been subject to legal challenge, the recommended next steps (outside the Determination) are: search Federal Court, Administrative Appeals Tribunal and local Territory court records; review Gazette entries for notices and amendments; and enquire with the Department that administers the Determination about any recorded disputes or internal review outcomes. The instrument itself provides no litigation narrative.

Several practical and legal traps are embedded in the instrument’s language and structure. Practitioners and affected parties should note the following concrete mechanics and potential friction points.

1. As‑applied definitions and cross‑references

• The Determination imports key terms from other Acts (s 4). For example, whether a property is “residential land” for the purposes of pensioner or senior concessions depends on the detailed tests in s 5 and on the meaning of “dwelling” in the Water Services Act 2012 (WA) (CI) (s 4). Disputes about category assignment (residential versus commercial/residential) will turn on fact and the imported statutory meanings.

2. Administrator discretion to vary fees

• The Administrator may agree in writing to lower fixed or quantity fees, including nil (s 6(3A), (4), (4A)), and may publish agreements (s 6(4B)). That discretion can change the effective charge for a specific property without a legislative amendment. Owners should not assume the Schedule is immutable; conversely, entitlement to a reduction requires the Administrator’s written agreement. The Determination does not set criteria for when the Administrator should exercise this discretion.

3. Notice timing and payment liability

• Liability to pay attaches when the Administrator sends a notice under s 6(5) (s 6(8)). The Determination mandates a minimum of 16 days from notice to due day (s 6(7)). A common practical issue is postal or email delay; the instrument ties the timing to the day the notice is sent rather than to receipt, which affects disputes about whether the minimum 16 days was provided.

4. Staged restriction process

• The Administrator must follow the reminder then notice-to-restrict sequence (s 9(2)-(5)). The reminder gives 10 days, the notice-to-restrict must allow not less than 7 days, and restriction can proceed only after those steps (s 9). Missing a step could invalidate a restriction. Owners facing restriction should check whether the Administrator complied with the procedure.

5. Pensioner quantity concession limit

• An eligible pensioner may pay quantity fees at the pensioner rate for up to 600 kL of water used if the pensioner is an occupier of residential land (s 7(2)). The concession’s per-kL reduction is 50% (s 7(4) definition). Careful attention is needed to apply the cap: quantities over 600 kL are not covered by the pensioner rate. The Determination does not detail pro rata calculation or partial period apportionment.

6. Discharge-to-sewer calculation and 95% discharge factor default

• For commercial/government/industrial discharge to sewer the number of kilolitres assessed is the Authority’s assessed usage times the discharge factor (Schedule 3 cl 2). The default discharge factor is 95% (Schedule 3 cl 3(a)), but the Administrator may agree a lower percentage in writing (Schedule 3 cl 3(b)). This is notable where a property’s water use includes non-sewer discharges (e.g. irrigation) , the default effectively assumes 95% of supplied water is discharged to sewer unless otherwise agreed, which will inflate sewer-usage charges unless the owner negotiates a lower factor.

7. High marginal quantity charges

• Residential quantity bands escalate sharply: for residential land, the per-kL fee rises to $6.067 for 501-750 kL and $10.432 over 750 kL (Schedule 3 item 1). Commercial/residential land over 150 kL faces $9.929 per kL (Schedule 3 item 2). These rates can lead to very large bills for high water users; owners should check meter sizing, shared services and submetering arrangements.

8. Strata and shared-service nuances

• Strata-titled commercial or industrial land that shares a water service has a specific fixed fee (Schedule 1 item 5). Similarly, strata sharing a major sewerage fixture pays a separate fee (Schedule 2 item 6). Allocation disputes among strata owners may arise if the Administrator issues a single notice to the owner or occupier; internal cost-sharing arrangements may not bind the Administrator.

9. Quoted-cost items and transparency

• Several items are “quoted cost” (Schedule 4 items 1, 2, 4, 9, 10). The instrument defines “quoted cost” as the cost quoted by a contractor engaged to perform the service (Schedule 4(2)). That means the fee depends on the contractor’s quote; there is potential for cost variance and dispute if contractors’ quotes are not standardised or if procurement rules are unclear.

10. Restoration fees and timing

• If supply is restricted, restoration fees are set ($241.90 or $384.39 depending on timing) (Schedule 4 item 8) and must be paid for re-connection under s 9(6)(a)(ii). Owners should be mindful that restoration fees are additional to outstanding charges.

11. Absence of explicit appeal or review process

• The Determination does not set out appeal rights against the Administrator’s billing decisions, agreement refusals, or measurement assessments. Remedies, if any, must be sought under the parent Ordinance, the Water Services Act 2012 (WA) (CI) or through judicial review, which is not referenced here.

12. Interaction with GRV-based sewerage charges

• Residential sewerage fixed fees use a rate in the dollar of gross rental value with minimum and maximum annual fees (Schedule 2 cl 1(a)-(c)). Disputes over GRV valuation under the Valuation of Land Act 1978 (WA) (CI) will affect sewerage bills but are governed by that valuation Act, not by this Determination.

These are concrete operational “gotchas” that arise from the Determination’s text, and they indicate where owners, occupiers and advisers should focus attention in billing, negotiation and dispute scenarios.

Compliance requires two parallel paths: (1) administrative compliance with notice and payment procedures; and (2) substantive compliance with property categorisation, meter configuration and application for concessions or agreements where appropriate.

Immediate operational steps for owners/occupiers

1. Establish whether your land fits a category in s 5. The Determination’s fees depend on explicit land categories (residential, commercial, industrial, vacant, government, mining, institutional/public, charitable, local government and strata situations) (s 5). Confirm whether your land is “residential” under s 5(2) (used wholly or primarily as a residence and not providing holiday accommodation) or falls into a non-residential category.

2. Confirm meter size and service configuration. Fixed fees for commercial/industrial land in Schedule 1 (item 2) are determined by meter size (15/20 mm, 25 mm, 40 mm, 50 mm, 80 mm, 100 mm, 150 mm). If your property shares a water service or a major fixture with others (strata), identify that fact because separate fixed fees apply (Schedule 1 item 5; Schedule 2 item 6).

3. Check the notice and due date when billed (s 6(5)-(7)). Make sure your records of when a notice was sent and whether the minimum 16 days was provided align with the Determination’s timing rule. Payment is due on or before the day specified (s 8).

4. If you are an eligible pensioner or senior, apply for the concession and ensure you meet ownership/occupation tests in s 7. For fixed-fee concessions, the pensioner or senior must be both owner and occupier of residential land (s 7(1), (3)). For the pensioner quantity concession (50% reduction up to 600 kL), the pensioner must be the occupier of residential land (s 7(2)). Keep documentary evidence of eligibility consistent with the Rates and Charges (Rebates and Deferments) Act 1992 (WA) (CI).

5. For properties likely to exceed threshold quantity bands, consider demand-management measures or metering changes. The quantity bands in Schedule 3 escalate steeply; avoid unforeseen high bills by monitoring usage and seeking submetering for commercial/residential mixes if feasible.

Negotiation and special arrangements 6. If you anticipate or experience payment difficulty, notify the Administrator promptly and seek a special payment arrangement under s 10. The Administrator may agree in writing to an arrangement if the owner/occupier notifies difficulties (s 10(1)); while the arrangement is in force, the fee is due according to that arrangement (s 10(2)). Early contact is necessary because s 9’s restriction steps only apply if no special payment arrangement is in force.

7. Consider negotiating a written fee reduction where circumstances justify it. The Administrator may agree in writing to reduce fixed fees or quantity fees for particular land (s 6(3A), (4)), including a nil amount (s 6(4A)). There is no statutory criteria in the Determination; the decision is discretionary. If negotiating, document the basis of the request, provide supporting evidence (e.g. atypical meter configuration, demonstrated non-sewer water uses, infrastructure defects), and seek a written agreement that can be published if the Administrator elects to do so (s 6(4B)).

Technical and measurement compliance 8. For commercial/government/industrial discharge to sewer, determine the discharge factor and, if 95% is not appropriate, seek a written agreement on a lower percentage under Schedule 3 cl 3(b). Also be prepared to engage with the Authority’s assessment methodology for kilolitres used (Schedule 3 cl 2), understanding that the number of kilolitres is “assessed by the Authority”.

9. For building works that trigger notices under s 82 of the Water Services Act 2012 (WA) (CI), pay the relevant fees in Schedule 5 and ensure applications and plumbing work meet the Water Services Act’s standards. Item 2 of Schedule 5 clarifies when land is “sewered” for the purpose of those fees (Schedule 5 cl 2).

Operational and procurement compliance 10. For quoted-cost services, obtain multiple contractor quotes where possible and maintain written records of the contractor’s quoted cost, because Schedule 4 charges are defined as the contractor’s quoted cost (Schedule 4(2)). Ensure contractors’ procurement and cost quotations are transparent to reduce dispute risk.

11. Where restoration after restriction may be required, budget for the restoration fee in Schedule 4 item 8. If restoration work is likely to occur outside weekdays, the higher fee applies.

Record-keeping and dispute readiness 12. Keep records of all notices, payment receipts, correspondence with the Administrator, special payment agreements, any written fee-reduction agreements and meter readings. These records are central to demonstrating compliance or to challenging alleged non-compliance with the Determination’s procedures (for example, compliance with the reminder and notice-to-restrict sequence in s 9).

13. If a billing decision or Administrator action appears inconsistent with the Determination (for example, restriction without the required notices or charging beyond published fee lines without a written agreement), seek internal review rights under the parent Ordinance or the Water Services Act, or consider judicial review if no alternative remedy exists. The Determination itself does not provide an appeal process.

In practical terms, compliance is a mix of checking categorisation and meter details, responding promptly to notices, seeking concessions or payment arrangements early when required, and documenting all interactions with the Administrator. Owners and occupiers should also monitor usage carefully against the tiered quantity rates in Schedule 3 to avoid sudden high bills.
