Walkerburn WwTW

Project Title



Scottish Water



The MCC South project was a cluster of 7 projects - Denholm, Walkerburn, Selkirk, Langholm, Stonehouse, Douglas & Troqueer

It was identified as part of Scottish Water’s Wastewater SR15 Capital Maintenance Programme to allow the works to comply with current Scottish Water Standards and Specifications and to ensure that the serviceability of the plant can be secured by replacing poorly performing assets.

Scottish Water engaged their wastewater infrastructure alliance partner, aBV, to manage the overall scheme, however, the detailed design and delivery of the scheme was carried out by aBV’s own tier 1 alliance partner, Ferrier Pumps.
