Effective drainage and sewerage networks contribute towards local flood risk mitigation and are crucial in ensuring surface water can be removed from the environment. Water and sewerage companies do have an important role and, following the 2019 Price Review, will be investing £1 billion over five years to reduce flood risk. The new drainage and sewerage (including wastewater) management planning process will help water and sewerage companies to collaborate with other stakeholders to undertake a comprehensive assessment of network capacity, the challenges and risks they face over a 25-year period, and to develop a robust five-year action plan. The companies are already developing non-statutory plans for publication in spring 2023 and the outcomes will input into the 2024 Price Review. All risk management authorities, which includes water and sewerage companies, must co-operate with each other in the interests of flood risk management and may share information for this purpose. The Government encourages all risk management authorities and stakeholders to engage with water and sewerage companies to help ensure comprehensive plans are produced. The Government is also legislating, through the Environment Bill, to make this planning process statutory and intends to amend the Flood Risk Management Functions Order 2010 to ensure that these plans are captured as a flood risk management function, encouraging co-operation and the sharing of information between risk management authorities.
