Serving All of Hexham
Septic tanks &
wastewater systems in Hexham
The Tyne Valley is one of the most rural parts of the North East — and one of the most complex for wastewater. The River Tyne runs through it, the ground conditions vary significantly, and a large proportion of properties have never been on mains drainage. We cover Hexham and the whole Tyne Valley corridor.

Hexham sits on the River Tyne, and so do hundreds of rural properties throughout the valley. That proximity creates a specific compliance challenge: under the General Binding Rules, no septic tank can discharge to the Tyne or any of its tributaries — and the Tyne Valley has more of these than almost anywhere else in the North East. The North Tyne, the South Tyne, the Devil's Water, the Dipton Burn, the Allen — the list goes on.
Many properties between Hexham and Haltwhistle — and throughout the Hadrian's Wall corridor — were built long before these regulations existed. Systems that have discharged to a nearby burn for decades are now non-compliant, and the issue often surfaces during property sales when solicitors check drainage arrangements.
ClearFlow covers Hexham and the whole Tyne Valley — from Corbridge and Riding Mill in the east to Haltwhistle and Bardon Mill in the west, and from Acomb and Wall in the north to the Allen Valleys in the south. Free site survey, fixed price, no call-out charge across all NE46, NE47, and NE48 postcodes.

Ground conditions
across Hexham
The Tyne Valley presents more watercourse compliance issues than most parts of Northumberland. The main Tyne, the North Tyne, the South Tyne, the Allen, the Devil's Water, and dozens of smaller burns and drains all flow through farmland and alongside rural properties. Any septic tank discharging to any of these is now illegal under the General Binding Rules.
Ground conditions along the valley floor tend to be river terrace gravels — which drain well but sit close to the water table near the river, making drainage field siting sensitive. Move up the valley sides and you encounter heavier boulder clay. In the Allen Valleys and towards the North Pennines fringe the soils become thinner and less predictable.
The Hadrian's Wall corridor adds another dimension — many properties here are in or near a World Heritage Site, which can affect planning and the visibility of above-ground elements. We understand the planning context and design systems that work within it.
