One of the most common questions asked about Weholite is how long will it last? The simple answer is that the design life of Weholite in standard gravity applications is well in excess of 100 years. This can be backed up from a variety of sources, but for the purpose of simplicity and ease, please refer to The European Plastic Pipes and Fittings Association (TEPPFA), which does fantastic work for the industry. TEPPFA carried out a two-year academic study, which was independently scrutinized, by Professor Heinz Dragaun from the Technical School for higher education (TGM) in Vienna.
What does this mean?
It means that designers, owners and operators can be confident that HDPE sewer systems will have an in-service life of at least 100 years when materials, products and installation practices meet the appropriate requirements. In the case of Weholite, those set out in BS EN 13476-2: Plastics piping systems for non-pressure underground drainage and sewerage. Structured-wall piping systems of unplasticized poly (vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE). A standard to which Weholite is fully approved, and one that only applies to totally plastic pipes.
Weholite is used in a variety of pipeline applications from simple road or rail culverts, to the more demanding inter process pipework on sewerage treatment plants. When used in conjunction with the endless array of bespoke chambers, manholes and fittings the Weholite system offers users opportunities to excel.
