North Suffolk Reservoir

A proposed reservoir for winter storage, located in North Suffolk.

North Suffolk Reservoir is a Nationally Significant Infrastructure Project (NSIP) developed by Essex and Suffolk Water, to construct a Winter Storage Reservoir. 

East Anglia is one of the driest parts of the country and has been confirmed by the Environment Agency as being a Serious Water Stressed Area. In Suffolk, Essex and Suffolk Water supply water to 300,000 people.

Essex and Suffolk Water are forecasting in their Water Resource Management Plan that there will not be enough water supply to meet forecasted demand over the next 25 years and beyond without additional investment.

A progress update on the North Suffolk Reservoir is expected in Spring / Summer 2026.

Further information can be found on the Applicant's (Essex and Suffolk Water) website.
