Water Resources Management Plan

Every five years we produce a Water Resources Management Plan to ensure water is available for our customers and communities.

Our plan sets out how we will provide a reliable, resilient, efficient and affordable water supply to customers from 2020 to 2080, whilst protecting the environment.

Our plan addresses the need to balance the availability of water supply with the demand for water from customers. Without action, we face the risk of a significant shortfall of water in the future in our region due to population growth and climate change. We also want to help protect the environment and improve the resilience of our water supplies to droughts and other challenges.

Water Resource Planning (WRP) tables 2020 - 2080

The purpose of the WRP tables is to assist readers of the main revised draft plan to understand how we have calculated our supply demand balance on a water resource zone (WRZ) level, along with presenting the timing of options selected to maintain this balance. These WRP tables are revised draft plan tables. Our WRP tables will be consistent with our revised Market Information tables.

Water Resources in the South East (WRSE)

Our revised draft WRMP19 has been developed alongside the WRSE regional water resource strategy. By clicking on the link below you will be able to read about the collaboration and technical work that we helped to support as a contributor to WRSE. WRSE has the aim of producing an affordable, sustainable and resilient regional strategy for water – one that delivers for customers, society and the environment across the whole of the South East of England. The document also provides some thinking and future direction on how the WRSE believe the regional coordination of water resource management in the South East could evolve over the coming years.

Trading and Procurement Code

The Trading and Procurement Code sets out the policies, principles and requirements that will apply in respect of trades of water between Affinity Water and third parties including other water companies. We will keep this Code up to date and available here. The approved Code will also be available on the Ofwat website.
