Drainage Services in Barnstaple

Barnstaple sits at the tidal limit of the River Taw, and its historic town centre carries Victorian clay drainage, much of it combined, over ground that includes river silt and alluvium near the estuary, where tidal influence can affect outfall levels and occasionally cause older surface water drains to back up during high spring tides combined with heavy rain.

Expansion towards Roundswell and other edges of the town since the 1980s has introduced modern separate drainage systems in plastic pipe, generally designed with surface water attenuation given the flood-sensitive estuary setting. Surrounding rural parishes typical of north Devon, including parts of Fremington and the wider Taw valley, include farms and outlying properties on septic tanks or small treatment plants.

We use CCTV survey to check for tidal backing and establish pipe material before recommending work, since estuary-side Barnstaple has drainage challenges distinct from inland Devon towns. High-pressure jetting clears silt from the tidal river ground, no-dig relining repairs cracked or displaced pipework without major excavation, and we carry out percolation testing for the area's rural septic tank properties.
