Drainage Services in Abertillery

Abertillery grew along the Ebbw Fach valley during the coal mining era, and its terraced streets climb steeply up the hillsides on clay-heavy ground that holds moisture through the wetter months. Drainage in these older areas is generally shallow Victorian clay pipe, laid at steep gradients to follow the natural slope, which can suffer from erosion of pipe joints over the long term as well as occasional settlement linked to the area's mining history.

The valley receives significant rainfall, and combined with the clay soils, this creates notable surface water runoff after storms, testing the capacity of older combined sewers in the town centre and lower-lying streets. Some outlying properties toward Llanhilleth and Brynithel, further from the main built-up area, rely on septic tanks, and the local clay ground requires careful percolation assessment before any new soakaway is installed.

We begin drainage assessments in Abertillery with CCTV surveys to check pipe condition and identify any mining-related ground settlement. High-pressure jetting clears blockages from silt and roots common on the steep terraced streets, and no-dig lining is often the best solution for damaged pipe running beneath the town's narrow gardens and paths.
