| The company today confirmed it is presently carrying out work in Balgillo Road in Broughty Ferry, and will be surveying other pipes in the city’s sewer system for defects.
Many of the sewer pipes date from the Victorian era and are leaky and crumbling in places.
However, new techniques mean that much of the replacement work can be tackled without having to dig up large sections of ground.
A Scottish Water spokesman said, “This work is being carried out by contractor Lanes For Drains, and will be done by patching and sliplining to reduce the amount of digging and disruption.
“The sewers in Broughty Ferry are about 100 years old, and parts of the network have deteriorated to the point where they need to be renewed.
“In Balgillo Road, for example, the sewer has been affected by roots, which have pushed through the walls of the sewer.
“This renewal work will add to the longevity of the sewer network, improve flows, prevent collapses and reduce both leakage and the ingress of water into the sewer network.
“Recent incidents with the sewers in Broughty Ferry, which involved a large collapse and a problem with subsidence around a manhole, were both repaired at the time, and are not related to the work in Balgillo Road.”
Specialists Lanes for Drains are using their “no dig” repair method in Balgillo Road.
This enables existing pipework to be made good without excavation by inserting a lining material into the “host” pipe.
This pipe-within-a-pipe approach also greatly speeds up the process of replacing defective sewer pipes.
The company will also be using CCTV cameras to carry out a survey of the city’s pipe network to check for problems.
The sewers will be graded according to their condition, with the poorest tackled first.
Lanes for Drains use endoscopic cameras to probe inside 75mm diameter pipes and “crawler camera rigs”, which inch their way along the sewer, for 900mm diameter pipes. |
