Drainage Services in Hedge End

Hedge End expanded rapidly from the 1970s onwards from a village into a substantial town, so the majority of its drainage is modern: plastic pipework with separated foul and surface water, planned gradients and, on the newest phases around Boorley Green, designed attenuation basins. The underlying ground is largely Wittering Formation clay and sand, which in the clay-dominated areas percolates slowly.

That clay is behind most structural faults locally. Seasonal shrink and swell moves pipework, opening joints in older sections, and soakaways in heavy clay silt up and waterlog rather than dispersing water, which is a frequent cause of standing water and surcharging gullies after prolonged rain. Across the estates, long shared private drain runs serving several properties are common, and they are where blockages recur and responsibility disputes arise. Older cores at Botley and Bursledon retain clay pipework of an earlier era with root ingress from mature trees.

We CCTV survey in Hedge End mainly to map shared private runs and confirm whether a fault is clay movement, root ingress or misuse. Jetting clears blockages across both modern and older pipework, no-dig lining repairs fractured sections beneath driveways and shared access without excavation, and any new surface-water system on clay ground is designed from measured percolation instead of an assumed soakaway.
