Williamsgate WTW >
Forming part of the £300M West Cumbria Water Supplies Project, Williamsgate Water Treatment Works near Cockermouth will treat 80million litres of raw water from Thirlmere Reservoir every day. The project aims to provide a resilient water supply by linking West-Cumbria with the rest of North-West England following the Environment Agency’s decision to withdraw the abstraction licence for Ennerdale Lake by 2022.

The Challenge
Crack control during early thermal shrinkage had to be very carefully controlled and monitored. The design and specification of the mass concrete structures had to balance the technical performance requirement with the economic viability of transportation distance and costs and carbon footprint.
The SOLID Approach
To overcome the various challenges, HAC (Part of SOLID) designed a concrete pour sequence which was determined by a matrix of concrete placing temperatures, concrete thicknesses and seasonal variations to limit cracking to pre-determined technical requirements. HAC (Part of SOLID)’s experience informed the rebar design to ensure a solution which optimised the technical specification with the economic outlay.
