Drainage Services in Chippenham

Chippenham sits on the River Avon where Cornbrash limestone meets Oxford Clay, giving generally moderate drainage that can still become saturated in low-lying parts of the town near the river. The historic centre and older residential streets have Victorian clay sewers, often combined, and the town's flood history means some of these older systems can experience additional pressure during periods of high river levels, occasionally leading to slower drainage in nearby streets.

Post-war growth around Pewsham and the town's western estates introduced separate clay and plastic pipework, generally reliable, though root ingress from mature gardens is a recurring cause of slow drains across these older suburban roads. Newer developments towards the eastern side of Chippenham use modern plastic pipe on shallower foundations, which generally performs well but can be more exposed to frost and accidental damage during landscaping in the first years after construction.

We approach Chippenham jobs with a CCTV survey first, useful for identifying whether high river levels are contributing to drainage problems in low-lying streets. High-pressure jetting clears root ingress and silt from across the town's pipe stock, and where a survey shows cracked or displaced clay we favour no-dig lining, particularly in the historic centre where excavation is more disruptive.
