Harthill Reservoir upgrade

We are investing £5 million to upgrade Harthill Reservoir in South Yorkshire.

The project

The reservoir, situated between Sheffield and Worksop near to the village of Harthill, was constructed more than 200 years ago to supply water to the Chesterfield Canal, located approximately two miles to the north.

From time to time we need to upgrade and improve the canal infrastructure to present day standards, and this project will involve redesigning the overflow spillway to increase the resilience of the reservoir.

Over the next few months, the Trust will be carrying out a range of ground investigation and topographical studies, as well as heritage and ecological assessments. This will help to inform plans to re-model the overflow spillway alongside other operational enhancements at the reservoir.

The main project is expected to start in 2022 and be completed within 12 months. We will keep reservoir water levels temporarily reduced until the upgrade work is completed.
