Sequence of Operations for Water Treatment for US Embassy Cotonou, Benin

The following is a sequence description which covers the step by step treatment process and the role each skid plays in the treatment scheme.

Water is currently supplied from either the city water main or a well water source. The water sources enter the building with a service valves for maintenance. Both water supplies are treated to meet primary and secondary EPA requirements for drinking water.

The treatment system is designed to treat either the municipal water supply or the well water supply. The water treatment system is designed to first treat a large volume of water which will be held in the Raw Water Cistern. The initial treatment removes sediment in the water and provides chlorination. This water is used as a storage basin for the Potable Water Treatment System, as well as Fire Protection and Irrigation. This cistern provides a 7 day water supply (Approximately 400,000L). The next phase of the treatment is designed to bring the Raw Water to EPA primary and secondary requirements for drinking water.

Once this water is treated, it is stored in the potable water cistern. Both cisterns are constantly circulated, monitored and maintained using the steps described below to prevent bacterial growth.

Initial Raw Water Treatment

Municipal Water Booster Pumps (Tag: U- MWP-1) The incoming water from the city water supply will pass through a duplex booster pump. This pump skid is designed to increase the water pressure and ensure that sufficient pressure is provided to overcome light dirt loading on the bag filters.

The pump skid consists of two pumps, each capable of producing 30 gpm at 50 psi. The pump system is designed to maintain a constant pressure in the line with VFD control. If the pressure drops due to a valve opening to fill the raw water cistern, the lead pump will automatically start and continue to run as long as the pressure is below the set…
