Drainage Services in Richmond upon Thames

Richmond upon Thames sits directly on the Thames floodplain, and the river's proximity means a naturally high water table across much of the borough, particularly in Twickenham, Teddington and riverside parts of Barnes. Older properties here often run on Victorian clay drainage, some combined, that can be affected by both heavy rainfall and periodic high river levels, occasionally requiring non-return valves to guard against backflow.

Kew and East Sheen, slightly further from the immediate riverside, have a mix of Edwardian and inter-war clay pipework, generally on somewhat better-draining gravel terraces, though mature trees in this well-established, leafy borough remain a consistent source of root ingress. Ham and other areas close to Richmond Park sit on lighter, sandier soils in places, which drain more readily but can still be affected by the generally high water table typical of this stretch of the Thames.

In Richmond we always start with a CCTV survey that checks specifically for river or groundwater influence on drainage performance, a genuine factor this close to the Thames. High-pressure jetting clears root and silt blockages common in the borough's older clay pipe network, and no-dig lining is often the preferred repair method for properties near the riverside where excavation is both disruptive and, in flood-risk areas, more complicated.
