Water Attenuation

Non-pressure stormwater management boxes

Polymer attenuation systems provide adaptable systems that manage surface water, and that meet the required lifetime.

Polymer attenuation systems are an effective solution for managing surface water and have a history of successful flood mitigation, they are covered by recognised standards and are compatible with complimentary measures.

Polymer attenuation systems are adaptable to wide range of requirements in both rural and urban applications, products are modular for choice of configuration and scale, and high water capacity modules save space.

Polymer attenuation systems can meet the required lifetime, BPF Pipes Group members manufacturer branded products that meet the long-term product performance test for this type of system, providing added assurance. Polymer systems have predictable performance and maintenance, and predictable volumes allow future proofing for climate change.

Meta-study, ‘100 years lifetime of plastic pipes,’ was carried out by the Polymer Competence Center in Leoben, Austria, and commissioned by TEPPFA, the European Plastic Pipes and Fittings Association. It is a statistical analysis based upon significant and independently verified research and findings from existing literature on the expected service lifetime of plastic pipes, and is detailed at TEPPFA website. 100 years lifetime of plastic pipes February 13th 2024
