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

To ask the Secretary of State for Environment, Food and Rural Affairs, what the target date is for the completion of works to upgrade the Stony Lane Wastewater Treatment plant in Christchurch; and whether the upgrade will require the removal of all phosphates.

The Government has made clear that reducing phosphorus pollution must be a priority for the water industry through setting a legally binding target to reduce phosphorus pollution by 80% by 2038 against a 2020 baseline, with an interim target of a 50% reduction by 2028.

Christchurch sewage treatment works is operated by Wessex Water Services Limited. All water companies, including Wessex Water, are currently developing their business plans for the next water industry investment period, and agreeing these plans with the water industry regulators.

These plans, including all upgrades which will be undertaken as part of the Water Industry National Environment Programme (WINEP), will be made available to the public after Ofwat’s final determination in December 2024. Until then, the Government is not able to share specific information around which sewage treatment works are, or are not, included in the programme.
