Sewers

Together, Polysewer and Ridgisewer make the largest range of WIS 4-35-01 Kitemarked structured wall pipe systems in the UK. In fact Ridgisewer is the only Kitemarked structured wall alternative to concrete pipes. Both Polysewer and Ridgisewer have the traditional benefits of plastic pipe systems e.g. strength and durability, but weigh as little as 6% of rigid pipes providing for easier handling and thus quicker and safer installation.
