Drainage Services in Exeter

Exeter's historic centre sits on a ridge above the River Exe, with Roman and medieval foundations beneath streets carrying Victorian clay drainage, much of it combined, particularly around St Leonards and Heavitree. The Exe valley's alluvial and river terrace deposits mean low-lying areas towards St Thomas and Exwick can have a higher water table and are more susceptible to surface water pressure during heavy rainfall.

Expansion since the mid-twentieth century, especially towards Pinhoe and the eastern edge of the city, has been built on separate foul and surface water systems in plastic pipe, designed with modern surface water attenuation given the increased development pressure on the Exe catchment. Topsham, with its estuary-side setting, has tidal influence affecting some older drainage outfalls near the waterfront.

We start with a CCTV survey to identify pipe material and any tidal or groundwater influence before recommending work, since Exeter's drainage age varies enormously between its historic core and expanding suburbs. High-pressure jetting clears root ingress and silt build-up, and no-dig relining repairs damaged clay or plastic pipework without disturbing the city's historic streets or newer estate landscaping.
