Pateshill Waste Water Treatment Plant

PMcK were appointed as the specialist electrical Sub Contractor on the project PMcK carried out the electrical Engineering Installation at the remote site to include five new intelligent control panels, a new SCADA system integrating new and existing plant and linked to Scottish Water’s head office control system, upgraded instrumentation throughout the site, an updated lime dosing system, a new ALBA dosing system, a new poly dosing system, two 40,000 litre storage tanks and upgrading four clarifiers and six rapid gravity filters, including motors, pumps, mixers and instrumentation.

Working alongside specialist and framework providers associated with the project, PMcK Installed all mains distribution cabling - communication fibres, profibus and Modbus cabling.

Due to the age of the plant, a large degree of reverse engineering was required. In total, c100 items of plant/instrumentation were replaced. whilst another 100 items were taken onto the new IMCC panels and SCADA system and approximately 1200-1500 signals were transferred from old redundant panels to the new SCADA System.
