The question

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment her Department has made of the potential impact of the proposed SESRO reservoir on the environment of the Thames Valley.

Answered by Emma Hardy

Assessments to understand the potential impacts of SESRO have been developed by Thames Water, working with environmental regulators, as part of the Regulators’ Alliance for Progressing Infrastructure Development (RAPID) gated planning process ahead of formal planning stages. For SESRO to proceed it will need to obtain a Development Consent Order as well as environmental permits. Through the Development Consent Order process, a full environmental impact assessment will be required to understand all environmental impacts from the scheme and to identify mitigation needed to protect the environment through both construction and operational phases. The Environment Agency (EA), along with other environmental regulators, is a statutory consultee for the process. Environmental assessments will also be required for any permits needed for the scheme, for which the EA is a regulator.
