Trenchless Sewer Repair
3 Key Benefits of Trenchless Sewer Replacement
- Reduces Costs: SUEZ can schedule repairs to cracks, holes, root intrusions, and leaky joints before they become costly emergencies.
- Reduces Time to Repair: No excavation is needed. Repairs can be made quickly.
- Reduces Infiltration: Dilution of sewage due to groundwater infiltration decreases the efficiency of treatment.
SUEZ’ Trenchless Sewer Repair gets the job done without having to tear up the road, meaning pipes can be fixed within hours not days. And SUEZ can schedule repairs to cracks, holes, root intrusions, and leaky joints before they become costly emergencies and, without having to interrupt the flow through your collection system.
SUEZ’ Trenchless Sewer Repair is also the most cost-effective way to combat infiltration, the seepage of groundwater into sewer pipes during heavy rains – a significant problem for older, compromised pipes.
How does SUEZ' Trenchless Sewer Repair work?
After accessing the network through a manhole or other existing access point, SUEZ workers insert an expandable stainless steel sleeve into the damaged pipe. SUEZ experts deliver the sleeve to the damaged area of the pipe with a robotic CCTV crawler. Because the installation packer is hollow, the sleeve can be installed while wastewater is still flowing.
Once it arrives at the repair site, SUEZ permanently locks the sleeve into position using an inflatable packer. The packer is then deflated and the robotic crawler is withdrawn. Because the trenchless sewer repair system is purely mechanical, no epoxy nor resins requiring cure times are used.
The stainless steel sleeves, which are warrantied for 50 years and are highly resistant to corrosion, are available from 6-inch to 32-inch circular pipe diameters and in lengths of 16-, 19- and 20 inches. For large repairs, such as longitudinal cracks, multiple sleeves can be interleaved.
Your city and ratepayers deserve a reliable collection system with fewer blockages, overflows and disruptions. SUEZ is committed to deploying the most efficient tools to make your infrastructure more resilient and therefore more affordable to your customers.
