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.

We will be carrying out further ground investigations in December, requiring a brief closure of the public footpath across the dam and the car park. The main project is expected to start in early summer 2022 and we will keep reservoir water levels temporarily reduced until this upgrade work is completed.

In January 2022, we will be hosting an online information meeting and survey to share more information on the proposed plans. Please continue to check this website for updates
