Glasgow Caledonian University | Water Treatment

Service: Water Treatment

Project: Glasgow Caledonian University

Client: Crown House Technologies

A Combined Heat and Power engine (CHP) and district heating supply has been installed as part of Campus Futures. The natural gas-fired CHP technology allows the University to generate on-site electricity. A by-product of that is recovering the heat produced during the process instead of it going to waste, which will be used to generate domestic hot water and assist with heating across campus. The CHP facility is linked through the district energy scheme to the campus via underground pipework. This £4.9 million investment not only services existing buildings but can be expanded to meet future growth of the campus and is expected to reduce the university’s carbon footprint by 750 tonnes per year.

Project Overview

Scope of works:

District energy provides numerous benefits which include:

  • Reduced carbon emissions
  • Improved energy efficiency
  • Reliability
  • Enhanced environmental protection
  • Reduced labour and maintenance
  • Enabling fuel flexibility
  • Reduced costs of energy generation
  • Increased fuel efficiency through use of CHP


Cleartech’s Approach

Cleartech’s team of highly experienced water treatment engineers carried out the chemical cleaning of the district heating system underground pipework to BSRIA BG29/2012 as per spec reference Y25.3030A. This involved carrying out a pre commission chemical clean, static flush, biocide wash and dynamic flush of the 27500 litre district heating system. Once this was complete, we dosed the system with 300 litres of Cleartech M26 – corrosion inhibitor, all in accordance with BSRIA Guide 29/2012 Pre-commission cleaning of pipework systems and as per Cleartech Specification 012.
