If you need building approval from a council or certifier, you need to get our approval too. Before you apply for connections to a new development – even to build a swimming pool or add a home extension – we must check and approve your building plan. This ensures your project won't damage our infrastructure or prevent us from working on it, and your building's protected if we need to work on our infrastructure.

If building or excavation works will affect our pipes, we'll connect you with a water servicing coordinator.

Your council or certifier tells you if you need a Section 73 Compliance Certificate when you develop or subdivide land. You can always access your application information. The application fee covers:

  • full assessment of your application and building plans by a technical expert
  • experienced case manager who looks after your application from start to finish
  • Section 73 Compliance Certificate and building plan approval when required work is complete.

Sydney Water Developer Direct emails a Notice of Requirements within 14 days of getting your application. If you don't need to construct any works, you'll get your Section 73 Compliance Certificate at the same time.

You need to apply for a meter at least 2 weeks before you start building so you'll have water on-site from day one. You can either:

  • ask us to install the meter – we’ll install it within 10 working days once we approve your application
  • tell us that you or your plumber will install the meter – you'll also need to apply for a connection approval letter.

Plumbers must apply to connect to our water, wastewater and stormwater pipes. Our Connecting to our systems policy explains more about our services and our requirements for connection. Your responsibilities when connected to our services policy lays out your rights and obligations once you're connected.

Apply to disconnect from a drinking water or wastewater service.

Apply to upsize or downsize your existing drinking water service or recycled water service.

Apply for approval if your project involves raising or lowering any Sydney Water asset. Assets include maintenance structures for drinking water, recycled water or wastewater.

If your business discharges trade wastewater, you must apply for our written approval so we can assess the operational, environmental and safety risks. We'll assess the outcome within 21 days and let you know what you need to do. We'll arrange an inspection after you start trading.

Find out more about requirements for commercial trade wastewater, industrial trade wastewater and grease traps and other pre-treatment.

If you're in a low-pressure area or you need to serve fire services or header tanks for multi-storey buildings, apply to boost the pressure of your drinking water service or pump to a wastewater outlet or gravity wastewater system.
