I often find myself being asked ‘why should I service my sewage treatment plant?’. My response is always the same. Do you MOT your car and service your boiler annually? The answer is usually a resounding yes. Well then why would you not service your sewage treatment plant? It treats the sewage from your home and releases it into the environment. It has a VERY important function and one that you rely on for day to day activities like showering, washing clothes, washing dishes and cleaning your teeth.
As the owner of a sewage treatment plant you have a duty of care by law as written in the Environment Agency General Binding Rules to ensure that your sewage must not cause pollution (Rule 4). You must also ensure your treatment system is regularly maintained in line with the manufacturer’s instructions. It is also stated that anyone who carries out maintenance on your system must be competent. Competent people include those on British Water’s list of accredited service engineers
(link https://www.britishwater.co.uk/page/ListofAccreditedServiceTechnicians) (Rule 11).
Most small domestic package sewage treatment plants on the market today have mechanical and electrical parts. These require maintenance every 12-18 months to ensure continued operation.
Should the motor seize on your Klargester Biodisc or the air blower fail on your WPL Diamond, GRAF or Solido sewage treatment plant, then there will be no treatment occurring within the plant. The system will then discharge untreated wastewater into the environment and cause pollution.
Other symptoms of sewage treatment plant failure may include the drains backing up, your toilets bubbling or overflowing, unpleasant smells and not to forget the costs of the repair and possibly a fine by the Environment Agency.
