Secondly, pipe areas targeted through the camera investigation are repaired using innovative trenchless relining techniques to correct faults, rather than being replaced. This is a and cost-effective way ‘no-dig’ of renewing the pipe. In most cases, the new pipes are formed on site by taking a continuous strip of profile and spirally winding it inside the damaged pipe, forming a new, water-tight structural pipe within the host pipe (see Figure 2.4). Trenchless Technology, this no-dig, cost-saving pipe renewal process will help prolong “Using the life of our sewer network, defer the need for expensive infrastructure upgrades and minimise any inconvenience to our customers. pipes and rehabilitating manholes also helps protect the environment and public “Relining health by reducing the amount of groundwater infiltration entering the sewer via pipeline cracks or faulty joints, allowing us to better manage sewage flows, especially in times of extreme wet weather.” Unitywater Manager Network Projects, Ashley Massie. – Case Study 3 South East Water – Overview
