Drainage Services in Griffithstown

Griffithstown developed in the late 19th century around the railway and tinplate industries, and its tightly packed terraced streets still largely retain the original Victorian clay drainage laid at the time of construction. The village sits on the valley floor near the confluence of several streams feeding the Afon Lwyd, meaning the water table can sit relatively high, particularly in the lower-lying streets closer to Sebastopol. Combined sewers are the norm through the older residential core, with foul and surface water carried together through pipework now well over a century old in places.

Small rear gardens and closely built terraces mean drainage runs are often shared or pass beneath neighbouring properties, which can make it difficult to trace the true source of a blockage without a camera survey. Mature trees along the valley streams and in the village's older gardens are a frequent contributor to root ingress in aging clay pipe joints. Later infill development towards Panteg and New Inn uses more modern plastic pipework, generally more resilient to the ground movement common in this part of the valley.

Our approach for Griffithstown starts with a CCTV survey, essential in these tightly built Victorian streets where original drainage layouts are rarely well documented and several properties may share a single run. High-pressure jetting clears grease and silt from the village's long-standing combined sewers, and no-dig relining allows repair of cracked or root-affected clay pipe without disturbing party walls or the small gardens typical of the area. Where flow issues persist, we investigate whether the low-lying position near the valley streams is contributing to a raised water table.
