The Water Resources Management Planning (WRMP) process is a Government-owned, statutory process aimed at ensuring water companies plan to maintain the security of water supply, including in drought, to customers as sustainably as possible, taking account of social and environmental impacts as well as economic costs.

There are a variety of complex methods that water companies use to calculate how much water they have available for supply and whether they have a surplus or deficit when compared to the demand for water. Waterwise acted as an expert advisor on this project, supporting the Environment Agency and Ofwat’s review of plans.

One outcome of the project was that Government requested water companies to demonstrate a “higher ambition on water efficiency” in their final water resources management plans.
