The soakaway, properly called a drainage field when it serves a septic tank or treatment plant, is where your system finally hands the water back to the ground. It is also the component that fails most expensively, because a clogged or collapsed drainage field usually means excavation and fresh land.

The villages and scattered farms around Shrewsbury are classic off-mains territory. Older properties typically run on septic tanks of varying vintages, newer rural builds and barn conversions on package treatment plants, and it is common for a property changing hands here to be the first time anyone has looked hard at the system in years.

Soakaway performance is decided by the soil. Free-draining sandy or loamy ground takes water readily; heavy clay barely takes it at all. Large parts of Shropshire, particularly across the north of the county, sit on glacial clays where percolation is poor, and that has to be respected in the design. A drainage field built without a proper percolation test is a drainage field built on hope.

Ground conditions around Shrewsbury

Ground around Shrewsbury is mixed. The Severn valley carries river terrace sands and gravels that generally drain well, while much of the surrounding farmland sits on glacial till with a heavy clay content where percolation tests need to be taken seriously before any soakaway is designed.

Watercourses and the rules around Shrewsbury

The Severn dominates the local drainage, fed by a network of brooks such as the Rea Brook and Cound Brook. Plenty of rural properties here have a ditch or watercourse within metres of the tank, which is exactly the situation the General Binding Rules were written for: septic tank discharge to those watercourses is no longer permitted.

Soakaway Installation & Repair: common questions

How do I know my soakaway is failing?

Typical signs are waterlogged or unusually lush ground over the field, effluent surfacing, odours, and a septic tank that refills or backs up quickly after emptying. Any of these is worth investigating promptly, before winter rain makes it worse.

What is a percolation test?

A measured test of how quickly water drains from trial holes in the proposed drainage field area, carried out to BS 6297. The result determines whether a drainage field is permitted and how large it must be.

Can a soakaway be repaired rather than replaced?

Sometimes. If the problem is a crushed pipe, root ingress, or a distribution box fault, repair is realistic. If the soil itself has sealed with sludge, replacement on fresh ground is usually the only durable fix, and we will tell you which case you are in.
