Companies covering chalk stream areas, such as Affinity Water and South Staffs Water, have made specific commitments to reduce abstraction from chalk streams. Affinity Water has committed to reducing abstraction by 34% by 2050. Portsmouth Water is building a new reservoir in Hampshire to protect the River Test and the River Itchen—this is the first new reservoir to be built since the 1970s. In June 2025, the Environment Agency updated its national framework for water resources, which set out the importance of chalk streams and how we will include their needs in water resources planning and decision-making.
