The WPL Diamond Sewage Treatment Plant offers a wastewater treatment solution that comes in two size options and meets all current regulations.

The Diamond DMS range is designed for up to 20 people, and the Diamond DMC range for between 20 and 55 people.
The Diamond’s sewage treatment efficiency will ‘clean’ wastewater to a standard of 20mg/l BOD5 and 30mg/l Suspended Solids on a 95 percentile basis.
Specifically designed for simple installation, high quality, odour free treatment and low maintenance and running costs, the Diamond has a simple design and robust construction which means a reliable operation, with no integral moving parts
The Diamond products meet the standards of BS EN 12566-3:2005, compliance with which became a legal requirement in the UK this month. BS EN 12566-3:2005 covers small wastewater treatment systems for up to 55 people and relates to plants with tanks made of concrete, steel, PVC-U, polyethylene, polypropylene and glass reinforced polyester. Packaged and / or site assembled small domestic and commercial wastewater treatment plants must all comply with the new standards of sewage treatment efficiency.
BS EN 12566-3 is the British version of the European-wide harmonised construction products standard which replaces all national standards. From July, only sewage treatment plants which have been type tested and approved to the new standard and CE marked can be marketed in this country. Merchants and other suppliers must not sell non-compliant products, and those responsible for specifying and installing such equipment must ensure that it complies with the new requirements from the due date.
