Drainage Services in Chelmsford

Chelmsford lies at the confluence of the Rivers Chelmer and Can, on London Clay that shrinks and swells noticeably with the seasons, a common cause of cracked or displaced drainage joints in the town's older housing stock. Moulsham and parts of the city centre retain Victorian and Edwardian clay pipe drainage, often combined systems, that can be tested by sudden heavy downpours given the proximity to the rivers and the modest gradient across much of the town.

Suburbs such as Broomfield and Great Baddow, built up through the mid-to-late 20th century, generally have separated foul and surface water drainage in clay or early plastic pipe, though the underlying clay subsoil still affects how well soakaways perform in wetter periods. Writtle and other village fringes retain some properties on septic tanks or small treatment plants, where percolation is directly affected by the heavy local clay.

For Chelmsford properties we begin with CCTV drain surveys to establish pipe age, material and the extent of any clay-related ground movement affecting joints. High-pressure jetting is effective on the silt and debris that collects in flatter sections near the rivers, and no-dig lining allows us to repair pipework beneath established gardens and driveways without major excavation. Where properties rely on septic systems near Writtle and other outlying areas, we carry out percolation testing to confirm drainage fields are still functioning adequately in the clay ground.
