Helping Northumbrian Water improve the security of drinking water supplies for its customers

Two of Northumbrian Water’s existing service reservoirs were at the end of their servicable life and in need of replacement. We were appointed to investigate the options available to improve the security of the drinking water supply to the demand area, which included up to 5,400 properties and a major industrial client.

We carried out a feasibility study which considered the options available, including replacing the reservoirs, refurbishing the reservoirs, and re-zoning of the existing water distribution network.

We identified the optimum solution to be the construction of a new service reservoir at a site adjacent to the existing structures. We were appointed by Northumbrian Water to undertake the detailed design of a new, 66m x 70m x 4.8m deep, 18.8 ML capacity service reservoir. Design services, including structural and geotechnical, were supported by our planning and ecological expertise, providing the client with the reassurance of a fully integrated approach. This approach continued through construction with the appointment of an AMEC ECC Supervisor, as well as ongoing design and commissioning support.

The new service reservoir was constructed in a manner which allowed the existing structures to be safely abandoned following commission of the new service reservoir and maintained potable water supply to customers during construction. This solution improves the security of Northumbrian Water's supply of drinking water to its customers in the most cost-effective way.
