A correctly installed system should work quietly in the background no smells, no backing up, no soggy patches in the garden. We design and install systems based on your site conditions, access, and discharge method, including:
Septic tank installation
Septic tank replacement
Package sewage treatment plant installation (ideal when you need a higher treatment standard or surface water discharge)
Where needed, we’ll assess ground suitability (including soil/percolation testing) and advise on the right solution drainage field, discharge route, and system sizing in line with UK requirements and best practice.
Regular maintenance helps prevent breakdowns, pollution risks, and nasty surprises (especially after heavy rain or in winter). We offer:
Septic tank servicing
Sewage treatment plant servicing
Planned maintenance reminders and practical advice
Support for homeowners, landlords and holiday lets
The Environment Agency’s guidance is clear that systems must be properly maintained and not cause pollution, and you may need to keep records (especially when selling)
Not every issue needs a full replacement but ignoring warning signs can turn a small repair into a major excavation.
Common reasons customers call us:
Slow flushing, gurgling drains, bad odours
Wet patches around the tank or drainage field
More frequent emptying than usual
Problems that appear after heavy rain (high groundwater / saturated ground)
We’ll inspect, diagnose the cause, and recommend the most cost-effective fix — from repairs and pipework to drainage field solutions.
Mortgage lenders and solicitors increasingly ask for checks on off-mains drainage. We provide practical, plain-English surveys to help you:
Understand what system you have (septic tank, treatment plant, cesspit/cesspool)
Confirm discharge type and likely compliance position
Identify red flags before you commit or negotiate
For an overview of what homeowners must do and how rules can differ for existing vs new systems, see the UK government guidance.
Local, straightforward advice (no scare tactics)
Systems designed around your land, not “one size fits all”
Clear quotes, clear timelines, tidy workmanship
Support with compliance led decisions (not guesswork)
We cover Dorset and surrounding areas (including Bournemouth, Poole, Christchurch and beyond).
Most septic tanks should be emptied at least once a year, depending on usage and tank size. Regular emptying helps prevent blockages, pollution, and costly repairs.
You may need to replace your septic tank if it:
Discharges directly to a ditch, stream or river
Is leaking or structurally damaged
No longer meets the Environment Agency General Binding Rules
In many cases, upgrading to a sewage treatment plant is the best long-term solution.
A septic tank provides basic treatment and relies heavily on a drainage field. A sewage treatment plant treats wastewater to a much higher standard, producing clear effluent that can often discharge to surface water where permitted.
Yes. Mortgage lenders and solicitors often require a septic tank or drainage survey to confirm the system type, condition, and compliance before completing a purchase.
In some cases, yes. Brick or concrete tanks with minor issues may be repairable. However, modern plastic or fibreglass tanks usually require replacement if structural integrity is compromised.
The cost of septic tank installation in the UK depends on ground conditions, access, tank size and discharge type. On average, prices can vary significantly, so a site assessment is always recommended to provide an accurate quote.
Common signs include slow draining sinks or toilets, unpleasant smells, water pooling near the tank or drainage field, and frequent need for emptying. Early inspection can prevent major damage and costly replacement.
Yes, septic tanks are legal in the UK, but they must comply with the Environment Agency General Binding Rules. Systems that discharge directly to surface water may need to be upgraded to a sewage treatment plant.
Yes. When a septic tank or drainage field begins to fail, it can cause internal drainage issues such as gurgling pipes, slow flushing toilets, and wastewater backing up into the property.
Most sewage treatment plants use a small amount of electricity to operate pumps or aeration systems. However, modern systems are designed to be energy-efficient and cost-effective to run.
