Drainage Services in Frome

Frome is built on a series of steep hillsides above the River Frome, with much of the older town centre sitting on limestone bedrock overlaid by thin, often shallow topsoil. The steep gradients mean drains can run at unusually sharp falls in places, which helps prevent silting but increases wear at bends and junctions in the town's Victorian clay pipework, particularly in the historic Trinity area. Later 20th-century development on flatter ground towards Berkley and Marston Gate sits on more consistent clay subsoil and typically uses plastic pipe installed to more standard falls.

The town's steep, narrow streets and stone terraces mean many original drain runs are shared or pass beneath neighbouring properties, which can complicate tracing a fault back to its source without a proper survey. Mature trees along Vallis Vale and in many of the town's older gardens are a regular cause of root ingress into aging clay joints, and shifting ground on the hillsides can gradually misalign pipe sections over time. Combined sewers remain common in the oldest parts of town, while newer estates use separate surface water and foul systems.

Our process for Frome properties begins with a CCTV survey to establish exactly how the drain run falls and where any root ingress, fracture or displaced joint has occurred, which matters more here than on flatter ground given the terrain. Where problems are structural but localised, no-dig lining avoids disturbing stone paving or retaining walls common on the hillside streets. High-pressure jetting deals with grease and silt in the older combined systems, and for outlying smallholdings around Critchill using private drainage, we carry out percolation testing to assess whether the soakaway is still performing.
