The Dimaond Range

The Diamond sewage treatment plants are designed with innovative features ensuring a reliable and effective means of treating effluent from properties not connected to mains drainage.

They are CE marked and have been tested in accordance with EN12566-3 making it fully compliant with UK building regulations, always make sure your new packaged sewage treatment plant has the CE marking.

The Diamond 6 with 570mm invert level is ideal for new builds and the replacement of existing tanks. The compact design of the units reduces installation and handling costs compared with other plants. The Diamond 6 gravity outlet reduces lifetime running costs as the final effluent gravitates out of the unit to a receiving drainage field or watercourse.

In Domestic applications serving population equivalents of up to 11 people the Diamond 11 can produce a final effluent meeting consent standards of 20mg/l Biological Oxygen Demand, 30mg/l Suspended Solids and 20mg/l Ammoniacal Nitrogen.

The Diamond 6 is also an ideal wastewater solution for many commercial applications such as; offices, factories, bed and breakfasts and other rural businesses. For help sizing your commercial property needs please click here.
