Drainage Services in Henley-on-Thames

Henley-on-Thames sits on the west bank of the Thames where the Chiltern chalk meets river gravels, giving low-lying streets near the riverside and Mill Meadows a naturally high water table. During wet winters and high river levels, groundwater can enter older drains and put pressure on combined sewers in the historic town centre.

The town's Georgian and Victorian streets around Hart Street and Bell Street retain much original clay drainage, often running beneath listed buildings and narrow yards, while later housing on the hillsides towards Harpsden and Rotherfield Greys uses concrete and plastic pipework. Rural properties in the surrounding Chiltern villages often depend on septic tanks or treatment plants.

We begin each Henley job with a CCTV survey to check for infiltration, root ingress and structural defects. High-pressure jetting clears silted and blocked runs, no-dig lining is particularly useful beneath historic properties and courtyards where excavation is impractical, and percolation testing supports private drainage work on the chalk hillsides.
