Cambridge Waste Water Treatment Plant Relocation Project

Anglian Water Services Ltd is proposing a new waste water treatment plant for Greater Cambridge. The proposal will be determined by the Secretary of State for Department for Environment, Food, and Rural Affair. The proposal includes the construction and operation of an Integrated Waste Water Treatment Centre and Sludge Treatment Plant, transfer tunnels, terminal and intermediate pumping stations, vehicle access, utilities connections, renewable energy generation, ancillary buildings and landscaping.

The project falls into the Nationally Significant Infrastructure Project (NSIP) process defined through the Planning Act 2008 (as amended) and will be considered under Part 3 Section 29 of the legislation. Responsibility for accepting and examining the NSIP application rests with the Secretary of State and not the local authorities, who are identified as statutory consultees, or ‘host’ authorities, in the NSIP process.

There are three ‘host’ authorities (Cambridgeshire County Council, South Cambridgeshire District Council, and Cambridge City Council) involved in this NSIP project. All three ‘host’ planning authorities have undertaken to work together as far as possible to ensure full scrutiny of this project takes place.

Have your say

It is important to note that as the ‘host’ planning authorities are not the determining authorities, any correspondence in relation to this matter needs to be directed to Anglian Water Services Ltd in the first instance and then the Planning Inspectorate. Anglian Water Services Ltd’s website contains further information on the proposal and how to have your say.

For further details of the NSIP process for this project, please visit the Planning Inspectorate (PINS) website.


The Examination began on 17 October 2023. It will last for a maximum of 6 months. Throughout the Examination period, Cambridgeshire County Council will submit technical responses as required by the Planning Inspectorate. All submissions made to the Planning Inspectorate will be published online and made available throughout the Examination period in the Examination Document Library.

More information, including the Examination timetable, can be found on the Planning Inspectorate’s webpage for this project.
