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

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 in Spring 2018. We sought feedback via an online survey, in focus groups and interviews, and held a number of events across our area. We received over 540 representations to the public consultation, as well as other feedback from customers.

In October 2018 we published a report, called the Statement of Response, setting out the comments we received, and explaining how we have taken these into account, alongside new information, in revising our draft plan. We have also published our revised draft plan. These documents are available to download below. The changes that we made to our draft plan are shown in highlighted text.

In Autumn 2018 we provided an opportunity for comment on the changes and revisions we have made to our draft plan. This further consultation closed on 28 November 2018. Thank you to everyone who responded.

What happens next

We'll carefully consider all the responses we have received to the further consultation.

In Spring 2019 we will publish an addendum to the revised draft WRMP19 setting out the consideration that we have given to representations received as part of the consultation and any further changes or revisions made to the revised draft WRMP19. The report will be sent to everyone who has participated in this phase of consultation and will also be published on our website.

This is a summary of the feedback received to the public consultation and the main changes made to our draft plan. 

Overview

This is our detailed report responding to the representations received to the public 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 draft plan, both as a result of feedback and new information.
