Drainage Services in Andover

Andover sits on chalk downland at the source of the River Anton, and the free-draining chalk generally supports good drainage across much of the town, though the historic centre still relies on Victorian clay pipework, some of it combined, that can be affected during periods of sustained heavy rain. Mature trees around the older parts of town are a recognised cause of root ingress into these older, shallower runs.

The town's substantial 1960s and 70s expansion brought planned separated drainage systems across estates like Charlton and East Anton, generally in clay giving way to plastic pipe, with consistent gradients that perform reliably under normal conditions. Weyhill and other village fringes include properties on septic tanks, where the chalk geology generally supports good percolation, though periodic high groundwater in the Anton valley can affect performance.

In Andover we start with a CCTV drain survey to establish pipe material and condition, distinguishing between the older town centre network and the more uniform pipework of the later estate expansion. High-pressure jetting clears root and silt blockages effectively in the chalk-influenced ground, and no-dig lining is a practical option for repairs in the historic centre where digging is more disruptive. For rural properties around Weyhill we also carry out percolation testing on septic drainage fields.
