SEWAGE

TREATMENT

Where connection to mains sewerage is not available, a sewage treatment plant can provide an effective and efficient solution. Increasing concern for the environment and new regulations has led many people to opt for a treatment plant rather than a traditional 
Septic tank system.

Treatment plants use the action of natural aerobic bacteria to clean sewage effluent to a level much higher than that obtained through septic tanks. This reduces the possibility of damage to soak away and treatment systems are particularly useful where soil has a low porosity.

Treatment plants use mechanical systems to aerate the sewage effluent, but are generally very quiet in operation, and – when correctly maintained a de-sludged – they should not cause any odour problems. Like septic tanks, they should be emptied of solid waste at least once a year.

For information about the size of treatment plant your property may require, contact us for free advice. When considering a new system, it should be noted that any discharge, from either a septic tank or treatment system, is subject to a discharge consent approval from the Environment Agency.

You can download guidance notes and an application form for consent to discharge from the EA website.
