Aquaspira Limited was delighted to host a visit from Pendle and Clitheroe MP Jonathan Hinder this month on Saturday 7th June.
The visit highlighted the Company’s investment in R&D with the focus on its latest innovation, a Ground Source Heat and Cooling recovery system which can be integrated into their stormwater, sewage and drainage management pipe products.
The Above Ground Demonstrator, which has been designed and built entirely here in Nelson, has been used to develop the technology. It replicates a heat recovery system and also incorporates sensors monitoring heat, fluid pressure/flow as well strain on the pipe. The data from the sensors is recorded and processed within the demonstrator and then communicated with the company’s servers where it will be analysed.
”It was great to visit Aquaspira in Nelson and see the cutting-edge work they’re doing. This kind of British innovation supports good jobs in Pendle, cuts carbon, and will ultimately cut energy bills for ordinary people.
These are exactly the kind of jobs I want to see more of in Pendle & Clitheroe, and I’ll keep working to support businesses like Aquaspira to grow and thrive.

Aquaspira CSR stormwater and sewage management systems are laid at an average invert depth of 4m. The incremental depth will provide substantially more reliable heat and cooling over traditional horizontally laid systems, and integration with the stormwater or sewage management system will significantly reduce costs. The developed system will represent a significant evolutionary step forward in sustainable energy technology and will assist the UK in achieving its carbon net zero targets.
The research into this new product will be run over the next 6 months and the testing should provide the company with the data to design a commercial trial site. Initially, the innovation will be relevant to new commercial builds, area heating schemes, data centres, commercial greenhouses and retail parks and over time ASL will continue research into more specialist applications, such as recovery of heat from sewage and industrial wastewater systems.
Once the research programme is complete the demonstrator will be repurposed to cool the manufacturing extrusion process, further reducing the Company’s carbon footprint.

The visit from Jonathan Hinder underlines ASL’s growing role in carbon reduction and its continuing investment in innovation, research and development. ASL are very grateful to Pendle Borough Council Innovation and Productivity Grants for their financial assistance and support to develop the above ground demonstrator.
”We are delighted to host Jonathan Hinder MP to Aquaspira. When complete, the current project should enable us to look for our first trial sites initially in the commercial construction sector. Aquaspira’s Integrated Ground Source Heat and Cooling invention will be a cost-effective way to reduce the consumption of carbon, contributing to the UK’s net zero objectives.
The R&D project will help us better understand the performance of our innovation and inform the design of the heat recovery system. We are also using the above ground trial to better understand the stress and strain acting on the waterway wall of Aquaspira CSR pipe.
