Water Resources Management Plan

Our draft WRMP 2024

We supply drinking water to over a million homes and businesses across the South East, but our water supplies face some big challenges. Our WRMP aims to make sure there’ll always be enough available.

It predicts how much water we’ll need for people, businesses and the environment in the future. As well as aiming to reduce the existing demand for water, we look at new sources, infrastructure – including reservoirs – water storage and new options such as desalination and water recycling.

What’s in our plan

The options in our plan are based on four priorities:

• Efficient use of water and minimal wastage across society means we’ll help customers reduce how much water they use and cut leaks by at least 50% by 2050.
• New water sources that provide resilient and sustainable supplies, including desalination, water recycling, reservoirs and transfers from other regions.
• A network that can move water around the region means making the best use of the water we already have and moving it to where it’s most needed.
• Catchment and nature-based solutions that improve the environment we rely upon to help increase the resilience of our existing sources.

Our plan contains a mix of these options at different times and in different places. To help explain our WRMP we've prepared a non-technical summary document.
