Septic Tanks & Water Treatment Plants

While both options manage wastewater where mains drainage isn’t available, there are notable differences. Septic tanks are simpler but require suitable soakaways, and can only be used when the ground conditions meet environmental rules. Treatment plants provide cleaner effluent, which makes them suitable for sensitive locations or clay soils common across parts of Kent.

Choosing the right system depends on your site, property size, and environmental considerations. Our engineers advise on the most appropriate solution after a survey.

Regular emptying is vital for system performance and to prevent blockages. Most tanks in Kent need pumping out every 12 months, though usage and tank size affect this. Our vacuum tankers remove the sludge safely and responsibly, protecting gardens and driveways during access.

We also check for signs of leaks, blockages and overflows on every visit. Maintenance visits help spot minor issues early, keeping systems in working order and within legal requirements.

Servicing a sewage treatment plant involves cleaning pumps, replacing filters, inspecting air blowers, and checking electrical controls. These tasks support reliable operation and meet Environment Agency requirements in Kent.

Routine visits prolong your plant’s lifespan and reduce the risk of costly breakdowns. We provide service reminders and written servicing records for all makes and models found in properties across Edenbridge, Penshurst and Riverhead.

Overflowing tanks, system backups or foul smells signal urgent issues. Sevenoaks Drains provides a 24/7 emergency response, targeting a one-hour arrival for properties across Biggin Hill, Otford and Sundridge.

Our team uses specialist tankers and jetting units to safely clear blockages and pump out the tank, restoring use and preventing property damage. Emergency support is available every day of the year with no call-out charge.

Sewage treatment plants are more advanced than septic tanks. These units actively treat and aerate wastewater, breaking down solids and reducing pollution before discharging the liquid. They’re often required for homes and businesses near watercourses in Kent or where stricter environmental standards apply.

Regular servicing keeps the complex pumps and blowers running efficiently. These systems are found in newer developments, commercial sites, and larger rural properties around Oxted, Westerham and Orpington.

Installing a septic tank involves excavation, pipework, and fitting the tank below ground, with careful planning around access and tank size. New installations for Sevenoaks and the surrounding villages follow strict UK building regulations and the latest General Binding Rules.

We arrange everything from site surveys to commissioning, and complete all ground reinstatement after works. Our engineers ensure tanks and soakaways are correctly sized for your property and local geology.

Cracks, broken baffles or damaged lids can lead to leaks or ground pollution. Our engineers handle repairs to concrete and plastic tanks, from patching small defects to replacing failed pipework and connections for homes in Dunton Green, Kemsing and Knockholt.

Where necessary, we provide written repair guarantees and always discuss the most cost-effective and practical repair options. Disruption is kept to a minimum, and safety around the tank site is prioritised.

Discharging wastewater from your septic tank or treatment plant must meet environmental standards. Regulations apply to nearly all properties in Sevenoaks and elsewhere in Kent, especially with watercourses or ditches nearby.

We advise on compliance, including consent to discharge, upgrades to existing tanks, and replacement where rules have changed. Regular inspections help you avoid fines and ensure your system works safely and legally.

A failing soakaway or drainage field can lead to pooling water, bad odours or slow-draining bathrooms. We use CCTV surveys and ground tests to assess soakaway pipes and chambers serving rural homes in West Kingsdown, Ightham and Shoreham.

Repair options include jetting, replacement of damaged pipework, or installing new drainage trenches where required. Keeping the drainage field in good order is essential for septic tank performance and drainage compliance.
