How we manage our property

And how you can access it

We have a diverse property portfolio that includes office accommodation, depots, laboratories, treatment plants, reservoirs, pumping stations and vacant land. We don't allow public access to most of them. This is so we can protect our assets and the water we supply to you. However, we do allow access in a variety of circumstances.

We may issue fines for unauthorised access or breaches to entry conditions of our sites. If you want to use, access or buy one of our properties, you'll need to give us detailed information. This will help us decide if it's acceptable or possible.

Visiting Prospect Reservoir picnic areas

We manage picnic areas at Prospect for the community to use and enjoy during set hours, subject to conditions of entry. WaterNSW owns and manages the reservoir itself and Prospect Nature Reserve.

The picnic grounds and cycleway are usually open to the public:

  • 6am–6:30pm during daylight savings
  • 7am–4:30pm at all other times. 

More about the picnic areas 

The picnic areas are located within the grounds of Prospect Reservoir on William Lawson Drive. This is just off Reservoir Road, Prospect, about 35 kilometres west of Sydney.

There are 3 picnic areas:

  • Andrew Campbell Reserve
  • George Maunder Reserve (upper and lower picnic areas)
  • Walder Park. 

Facilities include a viewing area and cycleway. All picnic areas have amenities and playground equipment, but there are no barbecue facilities and you can't light fires. 

The area also features many heritage sites. Sydney Water has a long history of managing Sydney's water supply, and Prospect is just one part of this. Learn more about our heritage conservation. Email us at if you have any questions.

About Prospect Reservoir
Prospect Nature Reserve is not open to the public as it is part of a Special Area Water Catchment controlled by WaterNSW.  Prospect Reservoir (242KB) is an integral part of the drinking water supply. It remains an important back-up water supply for most of our customers and remains a controlled site. 

Urban Plunge program at Prospect Reservoir 

Sydney Water's Urban Plunge program provided an exciting opportunity for the community to celebrate summer in Sydney. We hosted a free “pop-up” swim site in the parklands adjacent to Prospect Reservoir, in the heart of Western Sydney. The 8-week pop-up was designed to start a conversation with the community about swimming in our waterways and explore opportunities for more permanent places to swim across Greater Sydney. 

The pop up swim site has now been packed up and in storage until it ‘pops up’ next time. There is still lots to see and do in the parklands 

Find out more about Urban Plunge and how we are making our making our waterways swimmable. See here.
