The WPL Diamond range of package sewage treatment plants is specifically designed for properties not connected to mains drainage, in a range of sizes for population equivalents from 1-55 persons.

The unique design has no internal moving parts and therefore requires minimal annual maintenance, and has low running costs.

The continuous bacterial digestion treats the wastewater to a standard which meets normal Environment Agency consents and this treatment process can achieve a de-sludge period of up to 3 years, much longer than other plants available.

The Diamond is CE marked and type tested in accordance to the now mandatory BS EN12566-3, the new European standard covering small wastewater treatment plants, making it fully compliant with UK Building Regulations.

For larger sewage treatment solutions WPL offers the HiPAF SAF (Submerged Aerated Filter), a bespoke sewage treatment plant solution specifically designed to meet demanding, individual site requirements, for population equivalents from 1-3000 persons.

Combining versatility, efficient processing, reliability and a robust design, this plant meets Environment Agency standards, whilst minimising visual impact on the landscape.
