Modular Stormwater Attenuation System Ticks Sustainability Boxes |
The increasing focus on avoiding overloading drainage systems has led to growing use of stormwater attenuation systems as integral parts of developments ranging from modest domestic property projects to major industrial and commercial schemes.
As well as performance, the ability to meet sustainability criteria is critical to the correct system choice. Judged against these criteria the GEOlight system from Hepworth Building Products offers impressive credentials.
GEOlight is made from recycled PVC specially formulated to match the requirements of both heavier and lighter duty applications. The material specification is adjusted for each of two alternative products, providing compression strengths of 40 tonnes per square metre for trafficked areas and 20 tonnes per square metre for less arduous applications.
The sustainability benefits resulting from use of recycled, rather than prime polymers, are matched by installation, handling and water attenuation characteristics. Use of GEOlight reduces excavation requirements compared to traditional underground storage tanks. The lightweight 1 m3 modules can readily be handled on site without the requirement for heavy plant and the associated fuel usage and emissions. The modules join together quickly and easily to create the required tank size. Once in situ their interior ‘honeycomb’ design gives excellent bi-directional flow characteristics.
A perforated distributor pipe allows stormwater to fill the GEOlight units, both vertically and horizontally, during peak rainfall periods and enables water to be released to the drainage system in a controlled manner avoiding undue pressure on system capacity.
