Overstrand Municipality invited bids in 2014 to outsource the operation and maintenance of its bulk water and sewerage infrastructure. After a two-stage tender process (RFQ and RFP), Veolia Water Solutions and Technologies South Africa (Pty) Ltd was selected as the preferred bidder and later awarded the tender. Water and Sanitation Services South Africa (Pty) Ltd (WSSA), an unsuccessful bidder, challenged the award. WSSA alleged that Veolia’s bid did not comply with mandatory staffing requirements, particularly those prescribed by Regulation 2834 governing minimum numbers of qualified process controllers, and that Veolia failed to cost all required personnel, rendering price comparisons unfair. WSSA further contended that Veolia was impermissibly allowed to vary its bid during negotiations. The Western Cape High Court reviewed and set aside the tender award and remitted the matter for reconsideration. The Municipality appealed to the Supreme Court of Appeal.
