Drainage Services in Petersfield

Petersfield sits at the western edge of the South Downs, where greensand and clay geology gives generally moderate drainage, better than heavy clay but not as free-draining as the chalk further east. The town centre includes Georgian and Victorian buildings on clay pipe drainage, some combined, with mature trees around Petersfield Heath adding a recurring root ingress risk to older, shallower runs near the pond and heath.

Steep and Buriton, close to the downs, include a number of rural and semi-rural properties on septic tanks and small package treatment plants, where percolation depends heavily on whether the ground is greensand, which drains reasonably well, or the heavier clay found in the valley bottoms. Sheet and Langrish have a mix of inter-war and post-war housing with clay-to-plastic transitional pipework, generally performing adequately but still subject to root ingress in older sections.

We start work in Petersfield with a CCTV drain survey to establish pipe material and condition, and to identify whether a property sits on the more free-draining greensand or the heavier clay found locally, since this affects both pipe movement and septic system performance. High-pressure jetting clears root and silt blockages in the town's older clay pipework, and no-dig lining suits many properties around the historic centre and heath where excavation is impractical. For rural properties on septic systems we also carry out percolation testing on drainage fields.
