Our Diamond (formerly known as the WPL Diamond) compact package wastewater treatment plant is suitable for domestic and small commercial properties in all ground conditions where mains drainage is unavailable.
So simple
Unlike traditional septic tank systems, modern package wastewater (sewage) treatment plants are better designed for todays’ increased volume of water usage in everyday life. Our Diamond meets this growing demand and has an added advantage of a high quality process for wastewater treatment, in a compact, single tank. Easy to install and maintain, our range offers a longer term cost-saving solution.
So reliable
We offer you a 25 years tank warranty with each Diamond sold, backed up by our recommended list of independent network of experts who can install, service and maintain your plant.
So discreet
Our Diamond DMS (1 up to 20 people occupancy equivalent) and DMC (21-55 people occupancy equivalent) ranges are compact, odourless and entirely hidden below ground. With the flushest lids on the market, you won’t even know it’s there!
