Septic Tanks & Current Regulations

If your property is not connected to the mains sewer network, it is important that your wastewater system meets current standards. Septic tanks and sewage treatment plants both manage wastewater, but they work differently and the correct solution will depend on the property, the discharge point and the condition of the existing system.

Septic tanks separate solids from liquids, with effluent discharged to a soakaway or drainage field for further filtration.
Sewage treatment plants provide an additional treatment stage, producing a cleaner discharge suitable for approved outlets.
Older systems may need upgrading if they no longer meet current requirements or are showing signs of failure.
New installations should be designed and installed to suit the property, ground conditions and regulatory expectations.
Routine servicing helps keep systems operating efficiently and reduces the risk of expensive faults or breakdowns.
Professional assessment ensures the most suitable and compliant option is chosen from the outset.

At A.S.H. Environmental, we can assess your current setup, explain the options clearly and provide the right recommendation whether you need a septic tank installation, repairs to an existing system or an upgrade to a sewage treatment plant.

Septic Tank FAQs

When would I need a septic tank installation?

You may need a septic tank installation if your property is not connected to the mains sewer, if you are building a new rural property, replacing an old or failing system, or upgrading an existing off-mains drainage setup that no longer meets the needs of the property.

Can you replace an old or damaged septic tank?

Yes, A.S.H. Environmental can help replace old, damaged or unsuitable septic tanks. We can assess the existing system, identify any drainage or compliance issues and recommend the most practical replacement or upgrade option for the property.

Do septic tanks need to meet current regulations?

Yes, septic tank systems must be suitable for the property and comply with current requirements for off-mains drainage. If your system is old, discharging incorrectly or causing pollution concerns, it may need to be repaired, upgraded or replaced.

What is the difference between a septic tank and a sewage treatment plant?

A septic tank separates solids from wastewater and usually discharges treated liquid to a drainage field. A sewage treatment plant provides a higher level of treatment before discharge. The right option depends on the property, ground conditions, discharge route and regulatory requirements.

Can you repair septic tank systems?

Yes, we can help with septic tank repairs and off-mains drainage issues. Common problems include damaged tanks, blocked pipework, failed drainage fields, bad smells, slow drainage, overflows and systems that are no longer operating correctly.

How do I know if my septic tank is failing?

Signs of a failing septic tank can include unpleasant smells, slow drainage, sewage backing up, wet or boggy ground near the drainage field, overflowing inspection chambers or recurring drainage problems. A professional assessment can help identify the cause.

Do you work on rural and off-mains properties?

Yes, we regularly work on rural properties, farms, estates, homes and commercial sites that rely on off-mains drainage. Our team can help with septic tanks, sewage treatment plants, drainage fields and associated underground drainage works.

Which areas do you cover for septic tank installations?

We provide septic tank installation, repair and off-mains drainage services across Essex, Suffolk and Cambridgeshire, including Braintree, Chelmsford, Colchester, Bury St Edmunds, Newmarket and surrounding towns, villages and rural areas.
