Amiblu relining pipes replace damaged concrete sewer in Peterborough, UK

In December 2018, a section of the DN 1500 concrete sewer in Potters Way (housing estate in Peterborough) collapsed. A survey found that 1.79 km of the concrete pipework were severely damaged due to H2S attack. Anglian Water @one Alliance was commissioned to find a solution.

In the first phase of the project, a mix of CIPP (cured in place pipe) and GRP was used. The GRP pipes by Amiblu were lined in live flow conditions of approximately 850 liters per second.

In phase two, only Amiblu GRP relining pipes were used: 123 meters pipes DN 1700, SN 10,000 PN 1, and 447 meters pipes DN 1400, SN 10,000, PN 1 plus two additional bespoke bends with access shafts removed the need to replace manholes and ensured a continuous flow.
