Investment at Butterley Reservoir

Embsay Updated - April 2015 

Since January 2012, we've been consulting with residents and stakeholders about some necessary safety improvements to the overflow at Butterley Reservoir. The overflow (known as a spillway) plays a vital role in helping to keep people in the local area safe from flooding.

In order to meet legal requirements around safety, improvements are essential to the spillway. The improvements, once complete, will ensure that the overflow continues to effectively protect the reservoir embankment from flood erosion and continue to serve its purpose as intended by its Victorian engineers.

We considered several options and submitted a planning application for the only workable solution that delivers the safety requirements. This solution involves modifications to the existing spillway channel, maintaining existing masonry walls wherever possible. 

This option was initially refused by Kirklees Coouncil, but after careful consideration we decided to appeal this decision and an inquiry was held at the Media Centre in Huddersfield.

Following the week long inquiry, the Inspector upheld our appeal meaning that the scheme can now progress.

We're not expecting to carry out any work until much later this year and we'll continue to update and engage with local residents and stakeholders over the summer. 

For safety reasons, Butterley reservoir will continue to be drawn down by around six metres, along with two other reservoirs further up the valley. All three reservoirs will remain lowered until remedial works are carried out.
