Most of central Newcastle is connected to the public sewer — but the picture changes quickly once you move out towards the western fringe, the Tyne Valley, and the rural parishes that sit within the Newcastle city boundary or just beyond it. Properties in areas like Woolsington, Medburn, Heddon-on-the-Wall, Wylam, and the villages along the Tyne corridor frequently rely on private wastewater systems.
If your property is one of them, you need to know that the system is compliant, correctly sized, and properly maintained. ClearFlow provides the full range of septic tank and wastewater services across Newcastle and all surrounding NE postcodes — from free initial surveys through to installation, replacement, and long-term aftercare.
We're North East based. This is our home region, and we know the ground conditions, the local planning requirements, and the Environment Agency expectations for this area.
Our services in Newcastle
Everything you need,
in one place
Local knowledge
We know the ground
around Newcastle
Ground conditions across the Newcastle area vary considerably depending on where you are. The Tyne Valley corridor tends to have alluvial soils with reasonable drainage, which often supports a standard septic tank and drainage field. Move onto higher ground towards Ponteland, Woolsington, or the western parishes and you'll often encounter heavier clay soils that drain more slowly — which affects system design and sometimes rules out a simple soakaway.
Properties close to the River Tyne or its tributaries also need careful assessment under the General Binding Rules — any system discharging to or near a watercourse is illegal under the 2020 regulations, and the Tyne Valley has more of these situations than you might expect.
We've worked across this area for years. We know which ground conditions to expect in different parts of the city and its surrounds, and we factor that into every site survey — so you get the right recommendation first time, not a generic quote based on an assumption.

How It Works
From your first call
to a working system
Here's exactly what happens when you get in touch with us about a new septic Tanks installation in Newcastle.

Call or fill in the form. Tell us what's going on — new build, rural property, barn conversion. We'll ask a few questions and arrange a site visit, usually within a few days.
STEP 2
We survey and test
We visit the site, carry out percolation testing, and assess access and ground conditions. You get a written quote with a fixed price. No charge for the visit.
STEP 3
We sort paperwork
Before any groundworks start, we notify the Environment Agency and submit the Building Control application. You don't need to do anything.
