Drainage Services in Cirencester

Cirencester's town centre sits on Cotswold limestone with significant Roman archaeology close to the surface, a combination that means excavation for drainage work in the historic core often needs careful management alongside the usual Victorian clay pipework serving the town's older buildings. The limestone geology generally drains freely, but shallow soils over rock can mean drainage trenches follow unpredictable routes around outcrops, and older combined sewers near Watermoor can still be tested by sudden heavy rain.

Stratton and Chesterton, developed through the 20th century, have more consistent separated drainage systems in clay giving way to modern plastic, with fewer of the archaeological constraints found in the centre. Outlying villages such as Siddington and Baunton include properties on septic tanks and package treatment plants, where the free-draining limestone generally supports good percolation, though thin soils can occasionally limit drainage field capacity.

In Cirencester we start with a CCTV drain survey to establish pipe routes and material, which is particularly useful given the archaeological sensitivity of much of the town centre. High-pressure jetting clears blockages efficiently in the limestone-influenced ground, and no-dig lining is often the preferred method for repairs in the historic core where open excavation is restricted. For rural properties on septic systems, we carry out percolation testing to confirm drainage fields are performing well in the local limestone brash.
