The GEOlight stormwater management system from SDS has just been accepted by Wessex Water for a number of trial installations in conjunction with developers.

Peter George, development engineer for Wessex Water commented, “We were asked to approve the use of SDS systems by various developers on adoptable drainage and agreed to trial the system in a variety of sizes at various locations where the design, installation and operation of the system will be assessed for general acceptance.”

The GEOlight stormwater management system from SDS is an ultra lightweight honeycombed preformed modular structure made from recycled PVC which provides an underground stormwater storage facility for the application of stormwater attenuation or infiltration. The high void rate of up to 97%, high compressive strength of up to 1000kN/m2 and low resistance to water flow makes GEOlight a maintainable and cost efficient solution ideal for underground storage during storm conditions.

Richard Averley, sales and marketing director for SDS explained, “We are working with a number of water utility companies around the country and we are pleased to be working on this trial with Wessex Water. As designers, manufacturers and installers of these cellular structures, we are able to quickly adapt to different site conditions and any new criteria recommended by developers and utility companies.”

As well as attaining ISO 9001, the company is currently undergoing ISO 14001 Environmental Standard accreditation, demonstrating its commitment to developing an environmental management system in areas such as waste reduction and the use of recycled products. The SDS GEOlight stormwater management systems are manufactured entirely from post consumer PVC waste, normally destined for landfill. This reduces the carbon footprint and helps development projects achieve a higher BREEAM rating. Further investment has led SDS products to be BBA accredited, recognised by Achilles, and they have been submitted for WRc approval.
