Expert Septic Tank Services in Verwood, BH31 & Cranborne
Installation, Servicing, Maintenance & Repair
We offer a 2 Year Groundworks Warranty for installations for peace of mind.
In the 2020 & 2023 General Binding Rules, new regulations were introduced in England for septic tanks and treatment plants. All of our engineers have been trained on the new compliance rules.
Whether you are dealing with heavy heathland clay around Verwood and Three Legged Cross or navigating strict environmental rules across the Cranborne Chase, we can provide expert local advice on whether your old septic tank meets the up-to-date requirements or if your household sewage system needs to be updated with a treatment plant.
HOW DOES IT WORK?
A septic tank separates waste, whereas a treatment plant will clean your household waste before it deposits it back into a natural watercourse.
A septic tank is typically used when a property isn’t connected to the main sewer, they are designed to collect ‘greywater’ and ‘blackwater’ from households. Usually found in the countryside and installed underground, it performs approximately 45% of the treatment to the water within, the remaining treatment needs to be carried out in the soak away (drainage field) which requires expert installation and maintenance. The treated effluent exits the tank and enters the drainage field (also known as a leach field), where further natural processes occur to purify the water before it returns to the environment. A septic tank needs to be emptied regularly, the frequency at which is needs emptying depends on the size of the tank and the number of people using the sewage system.
For new and replacement septic tanks, expert installation is required. If you are unsure whether you comply with the latest regulations or want to discuss through your drainage options, Smartseptic can carry out a septic tank survey and provide a recommendation based on your needs. As well as initial surveys, we specialise in septic tank installation and maintenance. This ensures your tanking needs are catered for at all stages of the lifecycle.

Frequently Asked Questions
-
Because our main operational depot is situated just 5 miles away in Sandleheath, we can deploy an engineer or tanker down the B3081 to properties in Verwood, Alderholt, and Three Legged Cross within minutes. Call our emergency line on 0333 202 7129 for rapid BH31 response.
-
Verwood and surrounding Dorset villages sit on pockets of heavy clay and heathland soil that retain water during wet weather. High winter water tables can prevent traditional soakaways from draining properly, causing effluent to back up. We conduct soil percolation testing to design compliant drainage fields or specify direct-discharge treatment plants.
-
If your older brick or concrete septic tank drains straight into a local ditch or stream without a proper drainage field, it violates the UK General Binding Rules. This will be flagged on a buyer's survey and can halt your sale. We regularly carry out compliance upgrades so house sales can proceed smoothly.
