Drainage Services in Ealing

Ealing sits on London Clay overlaid by river terrace gravels associated with the Brent and its tributaries, a combination that has historically supported dense terraced development in Acton and central Ealing. Much of this housing stock runs on Victorian and Edwardian clay combined sewers, now well over a century old in places, and root ingress from mature street trees is a recurring issue in these older, shallow-laid pipe runs.

Hanwell and Greenford, closer to the River Brent, sit on lower, flatter ground where the water table can rise noticeably after sustained rain, occasionally affecting surface water drainage capacity in older combined systems. Northolt and Perivale, developed more through the inter-war and post-war periods, generally have better-separated foul and surface water systems in clay-to-plastic transitional pipework.

For Ealing properties we start with a CCTV drain survey to establish pipe material and condition across what is a genuinely varied borough in terms of housing age. High-pressure jetting clears the root and silt blockages typical of the older terraced streets, and no-dig lining is frequently used for repairs beneath shared driveways and party walls where excavation would be highly disruptive to neighbouring properties.
