Drainage Services in Lewes

Lewes sits on chalk of the South Downs where the River Ouse cuts through the town, and much of the historic centre is built on steep, terraced streets with narrow yards. Older properties around the Cliffe and School Hill often still run on Victorian salt-glazed clay pipework laid at awkward gradients, which is prone to root ingress from mature garden trees and to displacement as the chalk slowly settles. Combined sewers are common in the oldest parts of town, meaning heavy rain can quickly overwhelm capacity near the river.

Away from the centre, inter-war and 1960s estates around Nevill and Landport tend to have more consistent clay or early plastic pipe runs, though many have never been surveyed since installation. The chalk aquifer keeps the water table high after wet winters, which can flood low-lying gardens near the Ouse and put pressure on soakaways for surface water drains. Villages on the fringe, such as Barcombe, still rely on septic tanks and small package treatment plants where mains sewerage doesn't reach.

For any Lewes property we start with a CCTV drain survey to map pipe runs and identify root intrusion, fractures or misaligned joints typical of chalk ground movement. High-pressure jetting clears blockages without disturbing old brick or clay chambers, and where a pipe run under a listed building or steep bank can't be dug up, no-dig lining reinstates it with minimal disruption. For rural properties on septic systems we also carry out percolation testing to confirm the drainage field is still performing as it should.
