Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what assessment they have made of the growth in demand for water and sewerage services as a result of the population increase of the United Kingdom in the past five financial years.

The Government recognises the importance of having a robust drainage and wastewater system both now and for future demand. It is the responsibility of water and sewerage undertakers to plan to meet the needs of customers, including accounting for population growth. As part of the Environment Act 2021, a new duty has been created for water companies in England to produce Drainage and Wastewater Management Plans (DWMPs). DWMPs set out how a water company intends to improve their drainage and wastewater systems over the next 25 years, accounting for factors including growing population and changing environmental circumstances. These plans will help sewerage companies to fully assess the capacity of the drainage and wastewater network and develop collaborative solutions to current problems and future issues. The plans will bring together various stakeholders including local authorities and industry regulators. Taking a strategic approach to drainage and wastewater management, will help to identify and mitigate issues related to insufficient network capacity or damaged infrastructure.
