Home Protection enHanced as PolyPiPe delivers Flood alleviation solution to kidderminster estate Polypipe, the UK’s leading manufacturer of sustainable drainage and water management systems, has supplied a complete attenuation solution for the £1.3 million Kidderminster Linnet Rise Flood Alleviation Scheme. NMCNomenca and Severn Trent Water, Polypipe supplied a complete prefabricated solution using Polystorm geocellular tanks, together with pipework, manholes and catchpits all manufactured off site. The solution would also allow the installers to negotiate the very tight parameters of the Linnet Rise site, where space to maneuver plant equipment would be a challenge. The lack of capacity in the area’s existing highway drainage network placed many properties on the residential area of Linnet Rise at risk of flooding, with the consequences most recently seen in 2007, when thousands of pounds’ worth of damage was caused by a flood, following torrential rain. The solution delivered by Polypipe and NMCNomenca retrospectively addressed the site’s drainage issues for the long term, while keeping installation time and disruption to a minimum, showcasing the capabilities that Polypipe can offer when improving the standards of flood protection in heavily populated areas. Polypipe’s system was also fully adopted by Severn Trent Water. The scheme was designed to ensure a collaborative approach to solving the area’s flooding issues by providing a SuDS system that would provide long term defence with minimal intrusion to the existing space. Polypipe was approached due to its extensive track record of successfully delivering attenuation systems for developers and contractors. Working  closely with contractor The final design saw the installation of two Polystorm geocellular tanks at a depth of 3.2 metres, under two resident owned car parks
