Chalk Streams (Sewerage Investment) Bill

The Chalk Streams (Sewerage Investment) Bill requires water and sewerage companies operating in England to invest in infrastructure improvements specifically to protect chalk streams, unique, biologically diverse freshwater ecosystems found primarily in southern England. The bill aims to reduce sewage pollution and nutrient overload (particularly nitrogen and phosphorus) that damage these protected habitats. It sets binding investment targets and performance standards for companies, with enforcement mechanisms to ensure compliance. The legislation responds to environmental degradation in chalk streams caused by inadequate sewerage systems and agricultural runoff.
