Drainage Services in Kingston upon Thames

Kingston upon Thames sits directly on the river, on gravel terraces over London Clay that give reasonable natural drainage but also a consistently high water table given the immediate proximity to the Thames. The historic town centre and parts of Norbiton retain Victorian clay drainage, some combined, which can be affected by high river levels as much as by rainfall, particularly in the lowest-lying streets close to the water.

Surbiton and New Malden, developed substantially through the late Victorian and Edwardian periods as the railway expanded the town, have extensive clay pipe networks serving terraced and semi-detached housing, with mature street trees a frequent cause of root ingress. Tolworth and Berrylands, built up later, generally have separated foul and surface water systems in clay-to-plastic pipework performing more reliably under normal conditions.

In Kingston we start with a CCTV survey that checks specifically for river and groundwater influence, given the town's riverside position. High-pressure jetting is effective at clearing root and silt blockages in the older clay pipe network, and no-dig lining is often preferred for repairs near the riverside and in the town centre where excavation is both disruptive and, given the high water table, more technically difficult.
