Product Description

Clearwater E Range 2 Sewage Treatment Plant - 12 People 

The Clearwater sewage treatment plant E Range 2 will serve up to 12 people or a 6 bedroom property. The Clearwater E2 uses an aeration chamber rather than a rotating disc as in the Klargester BioDisc system, so no moving internal parts.

Gravity is the standard no cost option, however where the inlet to the watercourse or soakaway is higher than the outlet of the treatment plant you will require the optional Integral Pumped System (IPS) as this will pump the waste water uphill and into your discharge point. Depending upon site conditions the IPS system will pump from 1.0m head upto a distance of 200m or a maximum of 6.0m head with a distance of 15m


Three distinct process stages take place within the single tank. 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.

Returns Information

Customers may return items within 14 calendar days (as per our Terms & Conditions) - refer to 4.6 & 4.7. **

Please be aware that returning a tank can be complicated and expensive so please check that you are ordering the correct item (we suggest checking the dimensions very carefully).

Delivery Information


The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page.  Standard tank deliveries are "kerbside" which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.


Most accessories will be delivered within 1-3 working days. If you require them quicker, we can on occasions offer a next day service (please contact us to discuss). If the item(s) are out of stock we will advise you of the expected lead time and you will of course have the opportunity to cancel with a full refund.
