Instructions
You can access detailed capacity reports below that cover our major drinking water delivery systems and wastewater systems.
Disclaimer: Although we've made every effort to provide up-to-date information, it can be affected by many factors and is provided as a guide only. Sydney Water makes no representation, warranty, undertaking or guarantee (express or implied) that the information provided on this site is accurate, reliable or complete.
Information provided
The system capacity information provided here is a guide. It should be read in conjunction with the Sydney Water Growth Servicing Plan, which provides our timescales for servicing growth and additional advice on our planning strategy, processes and funding.
Our detailed system capacity reports are organised according to:
- water delivery system – which covers a specific geographical area supplied from a single water source, such as a water filtration plant
- water supply zone – which is part of a delivery system that's typically served from a single reservoir
- wastewater system – which is the system of pipes and pump stations for collecting and transporting wastewater from each property to a water resource recovery facility.
See our Explanatory notes to learn more about how we determine water and wastewater system capacity. If you have any queries, email urbangrowth@sydneywater.com.au. Please include 'System capacity enquiry' in the subject line.
Consultation with competitors
We've consulted with competitors to review the servicing information we publish, to discuss improvements and any other requirements. The Sydney Water Servicing Information Review provides a summary of the consultation process, information we currently publish, and additional information stakeholders asked us to include in our next update of published servicing information.
