Ambergate Service Reservoir at Fritchley has been an essential element of the water supply system to a significant number of customers in Derbyshire, Nottinghamshire and Leicestershire. It was first commissioned over 100 years ago, and although it has provided a reliable service during this time, it is nearing the end of its life in its current condition. The reservoir has exhibited significant cracking in the upper walls and is operated at a lower maximum water level than was originally intended. Similarly, the roof construction comprises a shallow barrel vaulted concrete roof which springs from steel beams which are showing significant signs of deterioration.

Challenges

The physical constraints of the site and the need to be able to keep the existing reservoir operational, meant that the design and construction team had to expose the west face of the existing buried reservoir to enable the new distribution chambers and pipework to be safely constructed between the new and old reservoirs.

Solutions

Close collaboration between STW and the design and construction teams enabled some significant value-engineering to be adopted on the pipework and valves, reducing the size of the large diameter pipework and chamber sizes. This saved cost on the project but more significantly gave the site team valuable working room to construct the new assets.

Results

The scheme provided an excellent example of a collaborative approach between Severn Trent, their construction delivery partners and designers delivering solution utilising innovative processes and adopting a DfMA approach to assist in meeting tight delivery deadlines.
