Veolia develops packaged treatment plant to treat borehole water in Stellenbosch

Veolia Water Technologies South Africa supplied a package plant for the treatment of water abstracted from two new boreholes at Cloetesville in Stellenbosch. The plant was commissioned in December 2018.

The packaged potable water treatment plant (PWTP™ 050) will treat 54 m3 of water per hour, which is fed into the municipality’s bulk water supply.

Fabricated in just 12 weeks at Veolia’s Water Techno Packages facility in Sebenza, Johannesburg, utilising off-the-shelf Veolia technologies, the plug-and-play PWTP™ was a cost-effective, efficient solution to rapidly supply the required treatment of borehole water to SANS 241 standards.

Water abstracted from the boreholes is pumped through an oxidation tank where manganese and iron are precipitated. It’s then pumped through a set of pressure sand and multimedia filters for suspended particulates removal. The water is then fed through activated carbon filtration, UV sterilisation and final polishing before being pumped into the municipal network. Veolia’s Hydrex™ chemical dosing is included in the various steps for process optimisation.

Veolia is currently responsible for an operations contract and is able to supply water treatment chemicals for the plant, independently of the municipal supply chain.
