Glencorse Water Treatment Works

Glencorse Water Treatment Works (WTW) is a newly built facility designed to deliver clearer, fresher drinking water to up to 450,000 customers across Edinburgh and parts of Midlothian.

Project Location

Pentland Hills near Edinburgh


Complete project almost two years (planning and supply of equipment)

It has replaced Scottish Water’s Fairmilehead and Alnwickhill Treatment Works which had reached the end of their operational lives. Glencorse is fed from reservoirs in the Scottish Borders. The Water Treatment Works is located on a greenfield site in the scenic Pentland Hills just under five miles from Edinburgh’s suburbs.

The Challenge

This was an intense project which involved working closely with the customer during the tender process for a year prior to the site’s start date. We then collaborated further with the planning and drawings, as well as being a supplier of equipment for a further ten months.

The Solution

Leada Acrow’s work on the Glencorse Water Treatment Works project involved the supply of designs and equipment for the retaining walls and the tank roof slabs. This involved Mammut Wall Formwork, MEP, MevaDec Aluminium Shoring, Co-Planar and Slimlite Soldiers. 

The Results

We are very proud to have worked on the Glencorse project. Back in 2005, we were appointed by M J Gleeson as the sole supplier of formwork and falsework systems for the £100 million Katrine Water Project and we firmly believe this work helped immeasurably to secure the Glencorse contract. The invaluable experience and strong relationships we developed there undoubtedly benefited the project at Glencorse.
