Septic tank and drainage services across The Welsh Marches

Off-mains drainage across The Welsh Marches

March country properties are overwhelmingly on private drainage: hill farms, remote cottages and village houses that no sewer will ever reach. Systems out here are often old, sometimes improvised, and frequently overdue the attention the 2020 rules now require.

Ground and soakaways

The border hills are old rock: shales, mudstones and volcanic outcrops carrying thin, stony, slow-draining soils, with better ground only in the valley bottoms. Slope, rock depth and spring lines shape every drainage field design in the Marches, and off-the-shelf answers rarely fit.

Watercourses and the rules

The Marches feed the Severn, the Vyrnwy, the Clun and the Teme from countless upland streams, and the Clun catchment holds some of England’s rarest river wildlife. Clean headwaters matter, and compliant drainage in these hills is part of keeping them clean.

Access and practicalities

This is the most demanding access anywhere in the county: high single-track lanes, steep valley climbs, and farms a long way from anywhere. Marches jobs need planning properly, visits are often worth combining to keep costs down, and the vehicle has to suit the lane rather than the other way round.
