Slide 26 Rainwater Harvesting OTHER APPLICATIONS - SOAKAWAY Soakaways are one of the fundamental elements of sustainable drainage systems aka SuDS. Soakaways are used to drain rainwater directly into the ground without connection to any mains drainage or sewerage pipes e.g. Rainwater downpipes. Skeletank is the first proprietary off-the-shelf soakaway. The Skeletank is a highly efficient soakaway without the same risk of siltation as a gravel alternative. The equivalent gravel alternative is 3 times the volume of a Skeletank Slide 27 Rainwater Harvesting Slide 28 OTHER APPLICATIONS ATTENUATION When it rains the Skeletank allows the rainwater to be stored temporarily and to be released in a very slow controlled manor. This system reduces the downstream flooding. This philosophy is known as attenuation. Attenuation can be used as part of a sustainable drainage system (SUDS) that is a planning condition prerequisite or a requirement of the buildings regulations Part H. Slide 29 Rainwater Harvesting Slide 30 OTHER APPLICATIONS OIL DRIP TRAY The Skeletank Oil Drip Tray (ODT) is a innovative new method to catch and retain oil drips and spillage. The Skeletank ODT is unique because it can retain oil but at the same time allow water to pass through to a local drain or soakaway The Skeletank ODT should never overflow due to inclement weather. There is also a secondary backup protection in the form of a Permafilter oil retention and treatment geotextile layer. It can be used for oil drum storage, refuelling of small plant such as generators and compressors or it can be constructed within a site refuelling compound to protect the environment and eliminate the need for regular tanker visits to remove trapped contaminated rainwater.
