South Africa: Cape Town calls for information on desalination solutions a mid drought
Cape Town has issued a request for information (RfI) about possible solutions to the city’s lack of water through desalination or other advanced water treatment. The RfI says that the city “seeks to gauge the interest of for-profit and non-profit entities in forming possible partnerships install and operate temporary reverse osmosis (RO) plants at various locations along its sea shore, and certain inland locations, and to inject the potable water into the water distribution network for a period”.
The aim is to produce 100,000 to 500,000 m3/d of potable water from seawater, other surface water, or run-off water, through a string of small (5,000 m3/d or less), medium (5,001 to 30,000 m3/d), and large (30,001 to 500,000) facilities along Cape Town’s shoreline and at certain inland locations. “These RO plants could be either modular, containerized, mounted on a barge, or mounted on a seagoing vessel,” the RfI says. The aim is to commission the first plants by August 2017.
