The charity making life better by water

We've announced essential upgrade scheme to Hill Top Reservoir in Slaithwaite

We're giving Hill Top Reservoir (Slaithwaite Reservoir) an essential multi-million-pound upgrade to ensure it remains resilient to climate change and continues to meet stringent safety standards.

Situated in the village of Slaithwaite in Huddersfield, the reservoir opened 225 years ago. Built by renowned canal engineer Benjamin Outram to supply water to the Huddersfield Narrow Canal, the reservoir remains an important water feed to the canal and is a well-used leisure resource for the local community, popular with walkers and anglers. 

Essential maintenance

We look after the reservoir and Huddersfield Narrow Canal, and has commissioned civil engineering company JN Bentley to undertake the works, to ensure that historic reservoirs like this are meeting present day standards (as required by the 1975 Reservoirs Act).

Essential maintenance and upgrade works are required to strengthen the centuries-old structure against the impacts of climate change and improve the performance of the reservoir by increasing the capacity of the spillway to hold more water and reduce leakage.

Ground investigation works are presently being carried out until January 2025 to inform the final plans. The public footpath at the top of the reservoir (from Holme Lane to Bank Gate) will remain open at this time.

From spring 2025, the main project is expected to start, with construction work due to begin onsite (subject to the permitted development application being agreed).  Completion is due in autumn 2026.

Vital structures

Sean McGinley, our Yorkshire and North East regional director, said: “Our reservoirs feed our canals and maintain water levels along the inland waterways. Their function is proving increasingly important to help us manage water levels during more frequent extreme weather conditions brought about by climate change, with drier summers and wetter winters.

“Originally constructed in the late 18th century, this reservoir, like much of our historic network, requires ongoing maintenance and upgrading to meet present day standards. 

“Our charity is undertaking a significant programme of investment to improve our large reservoirs across the country. This work will secure the long-term future of Hill Top Reservoir as an important resource for the Huddersfield Narrow Canal.”

Keeping you informed

We're working hard to minimise the impact of the project to all reservoir and canal users. During the construction phase there will be times when the water levels in the reservoir will be significantly reduced for safety reasons, and this will be carefully managed and monitored. There will also be temporary footpath closures in place. Latest updates will be shared through onsite signage and online.

We're keen to keep the local community and user groups informed about the project as it develops. We are writing to residents and hosting a drop-in meeting to introduce the project and invite questions on Wednesday 13 November 2024, 2:30-8:00pm at Slaithwaite Community Centre.

The team can be contacted by email: [email protected] or the Freephone information line: 0808 281 4669 (weekdays, excluding bank holidays, 9am – 5pm).

We're undertaking a significant programme of investment across their reservoirs to ensure they stay resilient to climate change and comply with the strict legislation that applies to all large reservoirs. Last financial year over £27 million was spent on resilience works at 19 of the Trust’s 71 large reservoirs.
