DRAINAGE IN FELTHAM

Drainage & blocked drains in Feltham

Feltham, Hanworth and Bedfont sit on flat, low-lying ground near the River Crane and Heathrow, where surface water can be as much of an issue as foul drainage.

Drainage in Feltham

Much of the housing in TW13 and TW14 is post-war, built on land with very little natural fall. Drainage laid across ground that flat has minimal gradient, so it depends on volume rather than slope to keep itself clean, and anything that settles tends to stay settled. Some of it is concrete pipe as well as clay, and concrete pipe fails differently to clay: rather than opening at the joints it erodes along the invert, the channel at the bottom where the flow runs, leaving a rough surface that catches everything passing over it.

The other Feltham issue is water arriving from outside. The River Crane, the Longford River and local ditches run through the area, and once the ground is saturated it drains slowly. In heavy rain surface water systems fill quickly, gullies back up, and in places where surface and foul drainage were combined or later cross-connected, that pressure ends up in the foul system. Near the airport, large areas of hardstanding send rainwater into the drains quickly.

Common drainage problems in Feltham

Flat ground, minimal fall

Post-war estates laid on level land. Solids settle instead of being carried away, so drains silt up gradually.

Eroded concrete invert

Post-war concrete pipe wears along the channel at the bottom, leaving a rough surface that snags debris.

Surface water flooding in heavy rain

Low ground and a lot of hardstanding. Gullies and interceptors need clearing before winter, not after.

LOCAL QUESTIONS

Drainage questions in Feltham

Common questions about drainage in Feltham, answered for the kind of property you find there.

Often it is capacity rather than a blockage. On flat, low-lying ground, heavy rain can fill the surface water system faster than it can drain, and it backs up at the gullies. Clearing silt out of the gullies and the connecting pipes buys back a lot of that capacity, and it is worth doing before winter rather than during it.

Clay opens up at the joints, so you get root ingress and displaced sections. Concrete tends to stay in one piece but erodes along the invert, the channel at the bottom where flow is constant. That leaves a rough, worn surface that catches debris, so the drain can block more often before anything looks structurally wrong.
