About this Webinar

Storm overflows on sewerage networks discharge raw and partially treated sewage into our water bodies and thus have a significant impact on water quality and amenity value. Under the Environment Act 2021 the government has a duty to secure a progressive reduction in the adverse impacts of these discharges. Ofwat, alongside colleagues from DEFRA and the EA, is currently considering how best to enable and incentivise this reduction in harm. The 2024 Price Review is an important, but not the only, regulatory tool Ofwat has at its disposal to facilitate change across the water industry. Through the 2024 Price Review Ofwat will set the price, investment and service package that customers receive, controlling prices companies can charge their customers. In doing so, we have a duty to balance consumers’ interests with the need to finance the delivery of water and sewerage services, ensuring they meet their other legal obligations, including a wide range of environmental and social duties.

This webinar will set out our current thinking on how best to reduce harm from storm overflow ahead of the publication of Ofwat’s PR24 final methodology in Dec 2022.
