Supplying specialist stop logs and delivering on site services to support safety and resilience at a key UK water asset
Blackhall Engineering is proud to announce a new contract award from Northumbrian Water for critical works at Whittle Dene Western Reservoir. The project further strengthens the collaborative partnership between the two organisations following recent successes at Selset.
Building on a legacy of trust and technical excellence, this latest contract sees Blackhall engaged to deliver a comprehensive package of services including the supply of specialist stop logs, along with on site valve support, confined space works, and underwater operations. These interventions are essential to enable safe access to and isolation of the critical valve, which is a key component within the reservoir infrastructure.
Blackhall’s site services team will be hands on throughout, supplying specialist stainless steel stop logs and supporting equipment including blanking plates and spindles. The team will also coordinate silt removal and work with a qualified dive team to enable safe underwater access to submerged assets.
“This project represents more than supply. It is about partnership and problem solving in the field. In collaboration with Stantec and Edwards Diving Services, our engineers will be on the ground throughout, working closely to ensure every component is installed, tested and commissioned safely and effectively. We are proud to support Northumbrian Water in delivering this important scheme at Whittle Dene.” – Dean Wheatley, Board Director, Blackhall Engineering
Though often hidden from view, stop logs play a critical role in enabling safe isolation and maintenance of major water assets. Their correct deployment reduces operational risk, improves inspection access and supports preventative maintenance, a growing focus for forward thinking utilities like Northumbrian Water.
With back to back awards from Northumbrian Water, Blackhall Engineering continues to demonstrate why its approach, combining innovation, craftsmanship and close collaboration, is trusted to safeguard some of the UK’s most critical water infrastructure.
