Drainage Services in Lymington

Lymington runs from the New Forest edge down a steep high street to a tidal river and harbour, and both ends of that slope create different drainage problems. Near the quay and along the river the ground is alluvium with a shallow, tidally influenced water table, so outfalls are restricted at high water and low-lying properties drain slowly at predictable times. The steep high street produces long, fast runs that scour high up and deposit silt where the gradient flattens near the bottom.

The Georgian and Victorian town centre has shallow clay pipework, some combined, beneath a conservation area of listed frontages and narrow paved streets, where any excavation is difficult. Away from the town, Pennington and Everton sit on Barton clay and gravels where seasonal ground movement opens joints and percolation is slow, while Sway, Boldre and the forest fringe include many properties on septic tanks and treatment plants that must meet the General Binding Rules — a real consideration given the protected habitats around the Solent shore.

We CCTV survey first in Lymington to identify whether the cause is tidal restriction, groundwater, clay movement or blockage. Jetting clears the silted low-gradient sections near the river, no-dig lining repairs pipework beneath the conservation area without excavation, and off-mains systems on the forest fringe are designed from measured percolation to meet current discharge standards.
