Drainage in Ferndown
Ferndown grew from a small heathland village into a real Dorset town, mostly in the 20th century. This recent history shapes its drainage. Many homes here were built in the era of uPVC and rigid plastic pipe, which resists roots better than clay. Still, that pipework is now reaching middle age.
Settlement in Ferndown's heathland soil can cause uPVC pipes to lose their fall over time. This slows drainage and lets solids build up. It can happen even where the pipe shows no cracks.
The ground here is mostly the Poole Formation: sandy, acidic, and free-draining. Ferndown rarely sees the high water table found near Poole Harbour. Still, loose sandy ground can shift, and drain runs can drift from their original line over the decades.
Homes around Cherry Grove and Cobham Road are among the more established parts of town. Surveys here increasingly find bent or out-of-shape pipes. This slow ground shift is the cause.
The River Stour runs south of Ferndown, through Longham and Hampreston. Its floodplain brings real risk to low-lying parts of East Parley and Parley Cross. The Stour catchment is large and reaches into Wiltshire. As a result, river levels can rise fast and stay high.
Drainage in homes near the floodplain can feel back-pressure from wet ground. This happens even when no water reaches the property itself.
Ferndown's industrial estate and shops along Ringwood Road have different needs. Trade waste, oils, and wash-down water need interceptors. This waste is not like home drainage, so it needs careful handling.
Our engineers know both sides of Ferndown: the residential heathland drainage, and the industrial estate's trade needs. We bring the right approach to each.
