Septic Tanks & Water Treatment Plants

Septic tanks are often chosen for older homes or outbuildings where space allows and regulations permit. They are a traditional option in many parts of rural Surrey including Englefield Green.

Water treatment plants offer improved treatment levels and may be required for new builds, renovations, or where the Environment Agency sets higher standards for discharge quality.

Periodic emptying removes sludge build-up to prevent overflow, odour, or soakaway blockages. For most properties, annual or biannual emptying is recommended to keep systems efficient and compliant.

Maintenance visits may include checks for leaks, scum levels, and the condition of baffles. Egham Drains provides scheduled or emergency emptying across Ashford, Chertsey, Addlestone and beyond.

Routine servicing helps maintain the performance of your treatment plant and ensures reliable outflow quality. This process includes cleaning diffusers, checking pumps and compressors, and inspecting electrical components.

Egham Drains offers planned maintenance contracts for private homes, schools, and small business premises in and around Egham and Staines.

Blocked or overflowing septic tanks need quick intervention to prevent property damage or contamination. Egham Drains provides 24/7 emergency call-outs across Surrey, with a 1-hour response target for urgent cases when possible.

We arrive with tanker units and equipment ready to empty tanks, clear blockages, and make safe temporary repairs if needed.

A sewage treatment plant is designed for more advanced wastewater processing. This system treats sewage so the final outflow is cleaner and safe to discharge to a watercourse, which can be important in sensitive areas like Wraysbury or Virginia Water.

Modern water treatment plants use aeration to help bacteria break down contaminants. These systems suit larger properties, small developments, and sites with stricter environmental requirements.

Installation begins with a site survey to assess ground conditions and access. Engineers design the right size of tank for your needs and handle all excavation, fitting, and safe connection of inlet and outlet pipes.

Homes in Stroude, Old Windsor, or Thorpe can depend on proper installation for reliable long-term use. Written guarantees are provided for all new systems installed by Egham Drains.

If you notice slow drains, sewage smells, or wet patches near the tank, repairs may be needed. Common problems include cracked chambers, blocked inlets, or faulty soakaway pipes.

Our certified engineers use CCTV surveys and excavation if required to locate and fix underlying issues. All repair work is fully insured and comes with a written guarantee.

Septic tanks and treatment plants must comply with current Environment Agency rules. Regular emptying and servicing are essential to prevent pollution and avoid fines, especially if you discharge to local watercourses near Thorpe or Ottershaw.

Our engineers provide written reports after each visit and can advise on upgrades if your current system does not meet new standards.

The drainage field (soakaway) is crucial to the functioning of your system. Regular checks can spot early signs of saturation, root intrusion, or pipe damage that might affect its performance.

We use CCTV surveys and, where necessary, localised excavation to repair or replace damaged soakaway sections. This keeps your septic or treatment plant fully operational and extends its lifespan.
