The borehole at Shifford’s Bridge is located in Shropshire, a rural agricultural area, where rising nitrate trends required improvements to maintain  supplies within strict water quality limits.

Two schemes were put forward by Mott MacDonald Bentley (MMB). One to provide blending in order to maintain nitrates within acceptable limits and the other to construct a nitrate removal plant. Severn Trent opted for the latter due to the nature of the facility. The new nitrate plant is capable of treating 3.3ML/d. The delivery team worked closely with the supply chain partners to ensure a ‘right first time’ approach.

This involved utilising the knowledge and experience of the integrated design team and 3D modelling. SPEL Tankstor underground attenuation tanks were incorporated with high level sensors to reduce the risk of overspill/leakage and preventing pollution to the  principal aquifer.

The final product has met or exceeded Severn Trent Water’s expectations with the new plants greater efficiency and reduced maintenance.

We have been privileged to work with MMB on this project and are pleased it has been such a success.
