The Parliamentary Under-Secretary of State, Department for Environment, Food and Rural Affairs (Baroness Hayman of Ullock) (Lab)

My Lords, I thank the noble Lord, Lord Bethell, for raising this important issue and tabling Amendment 52, and the noble Lord, Lord Blencathra, for moving it in his absence. I start by reassuring him that I always take the concerns expressed in this House very seriously. I think that we agree that understanding the impact of sewage discharges on the environmental health of rivers is vital. Clause 3 requires water companies to provide information on the frequency and duration of discharges from emergency overflows. These measurements will enable regulators and the public to see, in near real time, when a discharge from an emergency overflow has occurred, and how long it lasted for. This will, in turn, enable resource to be directed to investigate the cause as well as the impact of a discharge, and will enable the regulators to take enforcement action if it is required. However, this is just one measure that the Government will use to better understand the impact of sewage entering our waterways. New continuous water quality monitors will be installed at storm overflows from 2025 to continuously measure the impact of sewage discharges on the receiving watercourse. The information gathered from these monitors will be key in supporting fish populations. Requiring the installation of additional fish counters downstream of emergency overflows may require additional structures in the watercourse and may impose additional costs on water companies and their customers. This does not appear to be proportionate, given that emergency overflows should be used on only very limited occasions. The Government will therefore not accept this amendment. However, I hope that I have been able to reassure the noble Lord that the Government are using this Bill to enable quicker action to be taken to investigate discharges from emergency overflows.
