Efficient Heat from Treated Water

Hydromarque helps power Scotland’s first low-carbon manufacturing district

When FES Group needed robust pumps to support a cutting-edge district heating network at the Advanced Manufacturing Innovation District Scotland (AMIDS), they turned to Hydromarque.

This low-carbon network is helping to heat buildings at Scotland’s flagship innovation district with water that would otherwise be discharged into the river—delivering heat and hot water that’s up to 90% greener than a gas boiler.

Turning Final Effluent into Low-Carbon Heat

At the heart of the system is a clever piece of circular thinking:
Treated wastewater is diverted from the Scottish Water Laighpark site in Paisley into a new energy centre. Ambient heat is extracted from the water, passed through a heat exchanger, and delivered via a 3.7km underground pipe loop to the AMIDS district, where it’s upgraded by heat pumps in each building.

To make this process work reliably, three heavy-duty pumps were needed to lift treated effluent out of the outfall chamber and feed it into the heat exchanger system, with high flow rates and full confidence in uptime.

The Challenge

Flow requirement: 360 m³/hr per heat exchanger

Suction lift: -3.5m static head

Back pressure: 200kPa (20.4mH₂O)

Key considerations: Energy efficiency, ease of maintenance, and safety

With access and safety in mind, FES Group needed the pumps to be installed “high and dry”, above the fluid level, with no compromise on performance.

The Hydromarque solution

We supplied 3 x 10” Gorman-Rupp Super T Series self-priming pumps, each fitted with a 45kW motor. Despite their ability to handle 3" solids, these pumps operate at 79% efficiency, making them a smart choice for energy-conscious projects.

Thanks to Gorman-Rupp’s legendary self-priming design, the pumps could be positioned safely above ground, no need for manual priming or complicated setups. Each unit automatically removes air from the suction line and gets to work fast, without fuss.

Gorman-Rupp Super T Series pumps are ideal for effluent and heat recovery

Industry-proven performance, including in raw sewage, food processing, and recycling

Up to 7.5m suction lift for above-ground setups

Simple installation with minimal downtime

Reliable, rugged construction and built to last

Installation was smooth, the setup runs trouble-free, and the heating network is delivering low-carbon warmth to Scotland’s manufacturing leaders, powered in part by treated wastewater and Hydromarque expertise.
