Background Information

Severn Trent Water aims to provide an alternative water supply to any population greater than 20,000. The Sugarbrook Service Reservoir that is fed from a single source, Bellington Borehole, falls into this category. 

Solution

The outline solution developed by Severn Trent Water and provided to Sweco involved the construction of a Booster Pumping Station at Norton and a 7.6km long, 450mm diameter main from Norton Service Reservoir to the Bellington Borehole site. The pipeline allowed water to be transferred from the Frankley Water Treatment Works in Birmingham to the Sugarbrook Service Reservoir – thus providing Sugarbrook with an alternate supply. The pipeline route, that was mostly rural, crossed high pressure gas mains, major roads, railways and water courses. The main was designed to be constructed utilising a combination of open cut and auger bore techniques in order to minimise disruption at the crossings.


Sweco modelled the system and proved that by increasing the size of the main to 500mm diameter, the required flows could be achieved under gravity conditions. Deletion of the Booster Pumping Station from the design providing Severn Trent Water with both capital and operational cost savings.

The scheme design included a 7.6km long, 500mm diameter main from Norton Service Reservoir to the Bellington Borehole site.
