Design and Supply of a Containerised Sewage Treatment System for the British Foreign & Commonwealth Office (FCO)


Comments (0) 13th August 2020 /

Pollution Control have recently supplied a bespoke containerised eco-n-saf system to treat all the waste water at the British Embassy in Kabul, Afghanistan.

The request from the technical works manager at the Embassy was that the system should be an above ground modular containerised design. The sewage treatment plant must treat the maximum flow of 35m³ per day, be easy to install and movable for rapid de-commissioning & re-commissioniong.

The waste water is made up from on-site accommodation (toilets, showers etc) and a laundry.  The treated effluent was to be used for irrigation.

At present all sewage is held in a cesspit and periodically removed off-site by tanker.

The new containerised system included a primary/balance chamber, three eco-saf bio cells a lamella clarifier and an integral controls room. The bespoke design includes for solids reduction, bod reduction and final lamella clarification with reduction of total-n.

The containerised system was supplied to iso shipping container dimensions c/w ISO container locking mechanism.  Due to the harsh transport and site conditions a full high quality two-pack protective paint system was applied both internal and external.

Due to the difficulty of sending engineers to Kabul for the installation & commissioning all external connections were simplified to ensure a true ‘plug & play’ system.

The on-site engineer spent time at our facility for training and had a local site visit with one of our engineers to experience a service and maintenance of a similar system.
