There are several key reasons to choose a Diamond wastewater solution for your development:
- Minimal maintenance, low running cost – unlike other sewage treatment plants on the market, the Diamond’s unique design has no internal moving parts. This means that it requires minimal annual maintenance, making it economical to run.
- Kind to the environment – the Diamond’s treatment process requires no chemicals, so it’s kind to the environment.
- Minimal visual impact – the Diamond’s tank is buried entirely underground, so it has minimal visual impact.
- No smells – most other treatment plants have primary tanks which store settled solids and can emit odours. The Diamond has no primary tank and is therefore odour-free.
- Long emptying cycle – the Diamond’s continuous bacterial digestion treats wastewater to a standard that meets all normal Environment Agency consents. This treatment process can achieve a de-sludge (emptying) period of up to three years – much longer than that of most other plants.
The Diamond sits below ground and is straightforward to install – often without the need for concrete backfill. A comprehensive installation manual is supplied with each plant, which you should read thoroughly prior to installation. We recommend that you use an experienced and qualified installer.The plant is supplied with an air blower, together with an alarm and an enclosure to protect it from the weather. This comes with 10 metres of airline to connect the blower to the tank. The Diamond can accommodate longer airlines – up to 30 metres.
The WPL Diamond range offers sewage treatment plants for properties that are not connected to mains drainage. The DMS range includes a range of sizes suitable for 1-20 people and the DMC range includes sizes suitable for 21-55 people.
