Veolia grows footprint in southern Africa through VWS Envig Botswana

VWS Envig Botswana has gained significant market share in Botswana in the last few years by providing end-to-end drinking, sewage and process water solutions, and by building long-term trust relationships with long-term clients.

"VWS Envig Botswana has emerged a preferred supplier based on our full delivery capability and service offering that's available throughout the country," said VWS Envig Botswana MD, Peter Healy. "Our capabilities include helping the mining industry treat its wastewater for greater sustainability, and we've also been helping mining communities secure fresh water supply for day-to-day use."

A large copper mining company has commissioned a 75 m3/day trickling filter wastewater treatment plant to upgrade sewage generated by roughly 350 residents at its mine camp in north-eastern Botswana.

A second company has taken delivery of two trickling filter plants, which will be installed at its copper mining project in north-western Botswana for treating domestic sewage generated by nearly 900 people to within legislated standards before discharge into surface water streams.

The Damtshaa and Letlhakane diamond mines in the east are also in the process of acquiring drinking water plants with treatment capacities of 2 m3/h and 10 m3/h respectively. The plants will upgrade borehole water using fully containerised water treatment plants from Veolia, and are scheduled for completion by February, 2014.

In line with the country's sustainable water development programme,the Botswana government has also contracted VWS Envig Botswana to design and build a number of water treatment plants to improve water supply in rural communities.

Veolia was contracted to design, supply and install a 6 000 m3 per day potable water plant in Maun, northern Botswana, to help augment the supply from existing underground water sources. The plant, drawing water from the Thamalakane River, will be commissioned early in 2014 and will also be operated and maintained by VWS Envig Botswana for six months after commissioning.

The company is also currently undertaking water treatment projects for two rural villages: a 30 m3/day drinking water plant for Sorilatholo in the Kweneng district, and a 200 m³/day plant at Malatswai in the central district. "For these rural communities, the plants are a major step towards compliance with the drinking water standards in rural areas," said Healy.

Upgrades to previously installed plants have also become necessary, with a capacity increase at the Debswana Orapa diamond mine township. "We originally installed three reverse osmosis units at the site back in 2007, but with an increased demand for fresh water, we've had to install additional capacity with a 4th reverse osmosis skid, which has expanded thecapacity to 10,300 m3/day. "Since the original installation in 2007, we have implemented a comprehensive maintenance contract for the client to ensure a reliable water treatment service," added Healy.
