    Clearwater E12 BTA Range Sewage Treatment Plant - 12 People Description

    Clearwater E12 BTA Range 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 up to 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.


    • High performance rating
    • Can be discharged directly to a watercourse
    • Free from mechanical or electrical components within the unit - very low maintenance and running costs
    • Minimal visual impact on surroundings - low level cover with child safe locks
    • Controlled ventilation - minimises risk of odour nuisance
    • Failure Light and Isolator
    • Annual emptying


    • Integral Pumped System (IPS)
    • Increase Inlet from 1.0m to 1.5m

    All our Clearwater tanks are for delivery by customer offload. This entails the customer to acquire the right manpower and/or machinery to help unload the tank/s from the delivery vehicle.

    If you require assistance with offloading, we may be able to offer a tail lift (lowers the tank to the ground) or HIAB (lorry with a mounted crane to winch the tank off the delivery vehicle). Please contact us if this is required for delivery.

    Clearwater E12 BTA Range Sewage Treatment Plant - 12 People 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.


    Tanks Over 2500L – Articulated Lorry – Customer Offload:

    These tanks will be delivered on an articulated vehicle (approximately 16.5m long x 2.6m wide x 3m high) which has no offloading on board, it is the customer's responsibility to offload the tank, which may require a telehandler / forklift.  Curtain sided vehicles are also used, so please note that if there are obstacles or hanging branches on the road to the delivery site etc, the driver may refuse to drive the vehicle to the customer's location due to the possibility of damaging the vehicle. Please let us know if there are any obstructions before delivery, so we can arrange alternative transport.


    18 Tonne Tail Lift HGV

    This vehicle is the size of the largest bin lorries (for comparison) and is approximately 8.2m long x 2.6m wide x 4m high, often curtain sided so please note that if there are hanging branches etc, these vehicles will not attempt to drive down due to the possibility of damaging the vehicle and so it is recommended that a smaller vehicle is requested. Tanks will be lowered to the ground but not positioned as this is a kerbside delivery.  If a smaller vehicle is required, please email us at quoting your order number and name.


    HIAB Delivery

    HIAB delivery is available but must be requested and there will be an additional cost for this service. If a HIAB delivery is required, please email us at quoting your order number and name, and we will come back to you with a price for this service.



    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.
