Stormwater drainage areas are zones where Sydney Water Corporation has legal responsibility for managing stormwater systems — the pipes, drains, and channels that carry rainwater runoff.\n\n**Who it affects:**\n\n- **Property owners and developers** in the listed catchments — they may need Sydney Water approval for work affecting stormwater infrastructure\n- **Sydney Water Corporation** — it gains (or confirms) legal authority to build, maintain, and charge for stormwater services in these areas\n- **Local councils** — their responsibilities may be limited or shared with Sydney Water in these declared zones\n\n**Why it matters:**\n\nWithout this Order, Sydney Water might lack clear legal authority to manage stormwater in specific locations. The Order:\n- Replaces older orders (cleaning up the legal framework)\n- Creates a definitive list of 78 catchment areas (from A'Becketts Creek to Wolli Creek)\n- References detailed maps held by Sydney Water that show exact boundaries\n- Ensures someone is legally responsible for flood prevention and water quality management in these urban catchments\n\nThe Schedule includes well-known Sydney waterways like **Cooks River**, **Botany Wetlands**, **Centennial Park**, and the **Hawthorne Canal**, as well as newer areas like the **Wianamatta South Creek (Aerotropolis)** catchment (added in 2022)."}},"importantCases":[],"_links":{"self":"/api/acts/sydney-water-stormwater-drainage-areas-order-2011","history":"/api/acts/sydney-water-stormwater-drainage-areas-order-2011/history","analysis":"/api/acts/sydney-water-stormwater-drainage-areas-order-2011/analysis","conflicts":"/api/acts/sydney-water-stormwater-drainage-areas-order-2011/conflicts","importantCases":"/api/acts/sydney-water-stormwater-drainage-areas-order-2011/important-cases","documents":"/api/acts/sydney-water-stormwater-drainage-areas-order-2011/documents"}}
