Drainage Services in Crawley

Crawley was largely built as a planned New Town from the late 1940s onward, sitting on Weald Clay that drains slowly and holds moisture well after rain. Because so much of the town's housing dates from this coordinated post-war development, drainage systems here tend to be more consistent than in older towns, generally clay pipework on separate foul and surface water systems, though now old enough that root ingress and gradual pipe deterioration are becoming more common across the original neighbourhoods.

Later additions such as Furnace Green and Bewbush used more modern materials moving into plastic pipework, generally performing well, though the underlying heavy clay ground still causes some settlement-related issues over time regardless of pipe material. Older pockets of Crawley predating the New Town, particularly around the historic high street, retain some older combined drainage that behaves differently to the surrounding planned estates during heavy rainfall.

In Crawley we start with a CCTV survey to establish which generation of drainage infrastructure a property is connected to, since this affects the likely cause of any problem. High-pressure jetting clears blockages from root ingress and general debris across the town's mostly clay and plastic pipe stock, and where clay ground movement has caused cracking or displacement, no-dig lining offers a way to repair pipes without disrupting the town's well-established street layout.
