A company involved in an ambitious project to extract water from a Devon landfill site has received £4.7million from a leading private equity house.

LAT Water Ltd has invented a process capable of separating and recovering clean water from highly contaminated industrial water, using waste heat, thereby reducing greenhouse gas emissions. It has been treating wastewater from landfill sites so it doesn’t smell as bad or have to be removed off-site.

The company’s first installation at the Daxin landfill, in Shenyang, China, has been successfully operating for more than two years and has been followed by the construction of a showcase facility at Viridor’s Broadpath Landfill site near Tiverton.

The 21-month pilot project uses low-grade heat from landfill gas engines at ambient pressure to concentrate leachate and extract water.

Backed by a £548,000 Government grant, the project aims to achieve environmental benefits in retaining the water while reducing CO₂ emissions with a potential 80% reduction in removals by tanker.

Now London-based IW Capital has led and completed a successful investment in Berkshire-based LAT Water Ltd to accelerate its commercial growth in its sustainable wastewater treatment solutions globally, following its early successes in the º£½ÇÊÓƵ and China.

The LAT technology process is highly scalable and can be installed for treating flows from one cubic metre to more than 1,000 cubic metres per day of effluent, delivering up to 60% cost savings for the operator and contributing to reductions in greenhouse gas emissions.

The process is capable of treating wastewater for a wide range of applications, including, notably, the treatment of wastewater from landfill sites.
