Drainage Services in Trowbridge

Trowbridge sits on Oxford Clay along the River Biss, ground that retains moisture and drains slowly, particularly in the low-lying areas near the river that run through the town centre. Streets built up during Trowbridge's period as a wool trade centre in the 19th century have combined clay sewers, and the heavy local clay means these older pipes have experienced gradual ground movement over the decades, contributing to cracked joints and uneven flow.

Expansion through the 20th century towards Hilperton and the town's eastern edges brought separate clay and plastic drainage systems, generally more consistent, though the same clay ground conditions mean seasonal shrink-swell still affects pipe alignment over time regardless of when the pipes were laid. On the rural fringes towards Staverton and North Bradley, some properties remain on septic tanks, and the heavy clay soil here requires drainage fields to be sized generously since natural percolation is slow.

In Trowbridge we start with a CCTV survey to assess how the local clay ground has affected pipe condition over time. High-pressure jetting clears blockages from silt and root ingress across the town's mixed pipework, and where structural cracking is found we typically recommend no-dig lining as a way of repairing pipes without disturbing gardens and pavements that sit on this notoriously moisture-retentive clay.
