Clearwater treatment plants are ideal for single houses and employ the well proven aerobic biological process for the treatment of sewage.
In 2005, a new European Performance Standard was introduced. EN-12566 requires manufacturers to submit their product to a testing regime that accurately measures the performance of treatment plants up to 50 population.
These tests identify how much pollution the treatment plant removes from the sewage, what level of maintenance is required, and what power is absorbed.
By holding EN-12566 certification, the Clearwater treatment plant is approved for an exemption from a permit to discharge under the new EPP2 environmental legislation.

First, coarse solids are filtered and retained for gradual breakdown. Then the resulting liquid is continuously distributed over a plastic suspended filter by an integral lift, powered by a remotely sited blower.
Finally, the solids are allowed to settle and, under normal domestic conditions, treated water of 20mg/l BOD, 30mg/l S.S., 20mg/l Ammonia can be achieved.


You may find that your soakaway area/watercourse area is some distance away from the outlet pipe where the tretment plant releases the treated water. If this is the case, you may need to use a model which has the ability to pump treated water. These are our Integral Pump models (IPS).
