Drainage Services in Havant

Havant sits where chalk meets the coastal plain at the head of Langstone Harbour, and it has an unusual drainage characteristic: strong natural springs rise in the town, historically enough to power industry, and that spring water keeps groundwater levels high through much of the year. Any drain with open joints in the spring-affected ground takes in clean water continuously, filling the system and washing silt into the invert.

Closer to the water at Langstone and Bedhampton the ground is alluvium and clay with a shallow, tidally influenced water table, so outfalls can be restricted at high tide and low-lying properties see predictable slow drainage. The old town centre retains Victorian clay pipework, some combined, at shallow depth beneath narrow streets, while Leigh Park — a large post-war estate — has planned separated drainage in clay and plastic with consistent falls, where shared private runs are the usual source of trouble.

For Havant we always CCTV survey before pricing repairs, specifically to identify spring-fed groundwater infiltration, which is a genuine local factor and easily mistaken for a blockage. Jetting clears silt and root ingress in the older clay runs, sealing and no-dig lining stop infiltration in the affected lengths, and where drainage is tide-affected near the harbour we assess non-return valves and pumped options.
