Septic Tank Installation & Sewage Treatment Plant Servicing in Twickenham & South West London – Domestic & Commercial Experts

A septic tank collects and separates wastewater, requiring periodic emptying. A sewage treatment plant actively processes and treats waste, producing cleaner, eco-friendly discharge that meets strict environmental standards.

It depends on occupancy, soil conditions, space for a drainage field, discharge location, and budget. We survey your site in South West London to recommend a compliant, cost-effective septic tank or sewage treatment plant sized to your needs.

Yes, but older systems may not comply. Direct discharge from a septic tank to a watercourse is not permitted; many properties upgrade to a sewage treatment plant. We advise on compliance and upgrades in line with Environment Agency rules.

Most domestic installs fall under Building Regulations and General Binding Rules. Some sites need planning permission or an Environmental Permit (e.g., sensitive locations or high flows). We handle guidance and paperwork for you.

Sizing is based on population equivalent (bedrooms/occupancy) and usage. Undersized systems cause odours and overflows. We calculate the correct capacity and future-proof where appropriate.

A drainage field (soakaway) disperses treated effluent into the ground. Suitability depends on percolation test results and space. We carry out soil/percolation tests and design compliant drainage fields where required.

Typically every 12–18 months, depending on tank size and usage. Regular desludging prevents blockages, foul odours, and costly repairs.

Most STPs need professional servicing at least annually plus periodic desludging. Service intervals vary by model and load; we offer scheduled plans to keep your plant efficient and compliant.

Avoid wipes, sanitary items, fats/oils/grease, solvents, paints, coffee grounds, harsh chemicals, and excessive bleach. These harm bacteria, block pipework, and cause failures—especially in treatment plants.

Most systems do not need additives if used and maintained correctly. Regular servicing and desludging are more effective for long-term performance and compliance.

Yes—most STPs use blowers or pumps and require a power supply. Quality units are quiet; correct siting and servicing minimise noise. We’ll advise on power, ventilation, and placement during survey.
