Special Treatment for Caugh Hill
Caugh Hill Water Treatment Works is located in the Sperrin Mountains and takes water from the Glenedra River to treat and distributes up to 34 million litres of clean drinking water per day to customers in the North West. After fifty years in service Northern Ireland Water decided to refurbish the structure.
Dawson Wam Site Manager Brian Kelly approached SDG for their advice and expertise in developing a bespoke PVC Waterstop system. This allowed Dawson Wam to form box outs in the reinforced concrete wall. The box outs were to allow the passing of steel pipes through the wall and would be subsequently grouted securely to form an integral structurally sound wall. The PVC Waterstop enabled the box outs to be water tight once grouted. For this application SDG produced a bespoke system with six box outs all in one assembly which meant no welding on site and therefore eliminating the potential for leaking. All joints were welded under factory conditions and tested before dispatching ensuring full homogenous structurally sound, water tight system.
Commenting on the finished product and service Brian Kelly – Site Manager Dawson Wam, said:
“I had worked with SDG before on special factory fabricated PVC Waterstop Joints so when we looked at the complex arrangement on this project for the box outs and pipe penetrations I decided to engage with them again. I spoke to Ciaran Donnelly and after a few subsequent drawings emailed back and forth we agreed on the detail. SDG had the assembly on site within 3 days and saved us a lot of time on site with cutting and welding. We were able to lower the assembly into place in one piece with no concerns. I would most definitely engage in this service again”.
