Connect

The IWSS water grid connects communities from the north of Perth, east to the hills, through the city, to Mandurah and at times, to other water supply systems for the South West and Great Southern regions.

We connected the Goldfields to support the gold rush over 100 years ago. Since then, the water grid has connected numerous small towns and farms along the way. Today over 75% of all Western Australians are connected to our water grid.

Population growth, together with climate change means that we must be more creative about how we deliver services to meet our customer's needs. This includes moving water and wastewater around the system in the most efficient way, at levels of treatment that protect public health and the environment.

This section provides information about how our water, wastewater and drainage systems operate and how we can optimise their use. Importantly, water service delivery is linked to the land planning process and opportunities to better integrate these activities are also explored.

In Perth and the surrounding areas (not including the Goldfields pipeline), the Water Corporation manages a network of pipes and other infrastructure, which includes:

• 12 572km of water infrastructure
• 10 502km of wastewater infrastructure
• 952 kilometres of drainage channels
