Lead-Free Upgrades Without the Headaches
Replacing old lead supply pipes can be messy, time-consuming, and space-restricted—but it doesn’t have to be. One professional installer working in the Severn Trent Water region used a clever combination of SHalloduct and INSUduct to deliver a new water supply with minimal disruption and no compromise on quality or compliance. A future-ready upgrade, done cleanly and efficiently.
The Problem
Across many properties in the Severn Trent Water area, ageing lead supply pipes still remain in place. Upgrading these to safer, modern materials is a priority—but it’s not always straightforward.
Excavation to the full recommended depth of 750mm isn’t always possible due to space restrictions, driveways, or other utilities. Traditional methods would mean significant digging, disruption and cost for both installers and homeowners.
An alternative was needed—one that was quick to install, cost-effective, and met safety and regulatory standards.
To work around the space and depth issues, the installer took a smart approach: using trenchless techniques to bring the new pipe to the property boundary, then installing SHalloduct where the depth fell short of the recommended 750mm. This provided both mechanical protection and insulation for the shallow-run pipe.
From there, the pipe was brought up externally via INSUduct, safely routed above the damp-proof course and into the property—no need to enter the house during the works and no disruption to internal finishes.
The result? A fully upgraded, lead-free water supply, installed quickly, efficiently and with a professional finish—leaving both the homeowner and installer happy.
