Planning your future water supply 

We’re planning ahead to make sure we have enough water in the future.

Water is essential for everything we do - from having a drink, to washing our clothes, and flushing the loo. It’s also essential for a healthy environment and a prosperous economy.

Many people think there is plenty of water in the UK, but the South East of England is one of its driest regions and London gets less rain than Rome, Dallas and even Sydney. Our water supplies are being stretched further and further as the number of people living in our area increases. We have to plan ahead because the choices we make today will shape the water supply we can provide in the future.

Every 5 years we produce a water resources management plan (WRMP) which sets out how we will provide a secure and sustainable supply of water for our customers now and in the future, and support economic growth.

Our Water Resources Management Plan 2019

Consultation - Spring 2018

In February 2018 we published our draft plan which set out how we plan to provide a secure and sustainable supply of water for our customers for the next 80 years, from 2020 to 2100.

We ran a public consultation on the draft plan and received over 540 representations, as well as other feedback from customers.

In October 2018 we published a report, called the Statement of Response No 1, explaining our consideration of the feedback and the changes we had made to our draft plan.

Further consultation - Autumn 2018

In Autumn 2018 we provided an opportunity for comment on the changes we had made to our draft plan. This further consultation closed on 28 November 2018. We received over 750 representations. Thanks to everyone who responded.

We've reviewed all of the comments received and presented our consideration of the comments in our Statement of Response No 2. This document, like last time, sets out the comments received and explains how we have taken these into account, alongside new information, in updating sections of our revised draft plan.

In addition to the Statement of Response No 2 we’ve also produced a Summary document, an Update Note which sets out the amendments which have been made to our revised draft plan and some updated sections of our revised draft plan. These are available to download below. 

What happens next

The Department for Environment, Food and Rural Affairs will review our revised draft plan, and updated documents, and in consultation with the Environment Agency and other regulators will decide whether to approve our plan, request further changes to our plan, or recommend further scrutiny either through a public hearing or a public inquiry.

This is a summary of the feedback received to the further consultation and provides an update on our revised draft plan.

Overview - April 2019

This is our detailed report responding to the representations received to the further consultation. It is comprised of several documents.

Main Report

This presents an overview of the consultation process, the responses received, the main issues raised in the consultation, our consideration of them and the changes made to the revised draft plan, both as a result of feedback and new information.
