We’re tasked with planning the future of our region’s water resources along with ensuring we are equipped to maintain essential supplies in times of drought.

Water companies are required to prepare and maintain a Water Resources Management Plan on a five yearly cycle. The Plan sets out how we plan to manage supply and demand for the next 25 years. It examines strategic issues that affect available water and demand and details how we intend to maintain the balance between water supply and demand to ensure customers receive a continued reliable supply.

Draft Water Resources Management Plan 2024

We have to prepare and consult on a Water Resources Management Plan (WRMP) every five years. Since our last plan was published in 2019 we have been working with our stakeholders and customers on updating our proposals to look ahead to the next 25 years and a draft is now ready for consultation. 

Our draft WRMP sets out how we will make sure there continues to be a secure supply of water to our customers in the future, while also protecting and enhancing the environment. It sets out how we plan to manage water resources, considering changes in customer demand, and continue to support the region’s economic growth and the wellbeing of those that work and live here.

We would like you to have your say in shaping our draft WRMP. The public consultation on our draft WRMP will run for a period of 12 weeks from 14th February to 9th May 2023

The Customer Summary provides an overview of what is in the draft plan, and will help you navigate the main chapters of the plan (below).

You are free to provide any response or ask any questions you like via this consultation process, however, we have provided several questions in the Customer Summary which may provide a helpful guide.

* To maintain the security of the water we supply to our customers and in compliance with national security requirements as described in the Water Industry Act 1991 section 37(B), it is sometimes necessary for some information to be removed (or ‘redacted’) from the WRMP documents that we have issued for public consultation. However, it has not been necessary for any information to be redacted from our draft WRMP and the full unaltered content that has been shared with our regulators has also been made available to the public.

Water Resources Management Plan 2019

We reviewed our previous Water Resources Management Plan from 2014 and updated it to produce a new Draft Water Resources Management Plan, which we submitted to Defra in December 2017. Following permission being granted by Defra, the new Water Resources Management Plan was published for public consultation in March 2018.  After the public consultation period we prepared a Statement Of Response, which outlined the changes we made to the Plan in response to the comments we received.  In July 2019 Defra granted us permission to publish our final plan.

The Plan has been prepared in accordance with guidelines issued by the Environment Agency. We are a member of the West Country Water Resources Group and are working with other water companies regarding transfers between Water Companies. We are also working with the Environment Agency on proposals for the Lower Otter Restoration Project.
