Bitou Municipality (Plettenberg Bay), Western Cape

VWS South Africa supplied a turnkey seawater desalination plant to produce 2 megalitres of potable water per day.

With limited coastline space, and environmental as well as aesthetic concerns in mind, the Municipality required VWS South Africa to design and build the potable water treatment plant within a tight deadline.

Sea water is sourced from seven boreholes at a depth of 12m each, sunk close to the landmark Beacon Isle Hotel where the beach sand acts as a first phase filter. The water is then pumped and treated by sea water reverse osmosis membranes. Brine water is discharged into the sea where wave action disperses and minimises salinity. The building housing the plant is also covered in indigenous succulents, minimising noise and improving the plant's aesthetics.
