Nearly 300 metres of sewers in Bristol will be given a new lease of life later this month, with robots replacing noisy drilling to keep disruption to the city centre community to a minimum. The £65,000 scheme will see sections of pipe around the Old City area revitalised to ensure the integrity of their structure, with Wessex Water continuing to use its innovative approach to renovate the system.
Instead of digging up long stretches of roads, taking many months to complete and generating significant amounts of carbon, the existing sewers are being relined using specialist equipment deep underground that requires just a few excavations in certain locations.
Reusing the existing pipework, teams will insert a new liner inside which reduces the risk of leaks and potential sewer collapses, helping to prevent the escape of waste water and infiltration of ground water. Robots work their way along the pipework to complete the work and make connections.
