City of Cape Town tender 32Q/2026/27; procurement locality plan, not construction progress

City of Cape Town tender 32Q/2026/27 combines a new 1,100 L/s Rietvlei sewage pump station about 14 m below ground, twin approximately 1.98 km DN710 HDPE rising mains and a 758 L/s bypass pump station with screening and degritting at Bellville Wastewater Treatment Works. The January 2026 capital budget lists ZAR 879.34 million as total project or programme cost, while the live tender publishes no contract estimate or awardee. Bids close at 10:00 local time on 2 November 2026.

The issued scope fixes the hydraulic package

The eTenders OCDS release establishes the active open tender, buyer, dates, CIDB estimate, clarification requirement and current no-award state. The City-issued tender extract establishes the 1,100 L/s station, approximate depth, twin 1,980 m DN710 mains, 758 L/s Bellville bypass and named headworks. The January 2026 City budget establishes ZAR 879.34 million as total project or programme cost and records completed detailed design; it does not publish the tender or award value. The Bellville facility photograph is adjacent operating context only.

Three coupled workfronts shape the supplier chain

The tender couples civil, pipeline and electromechanical scope rather than replacing one pump in isolation. Deep excavation and groundwater control must integrate with live-flow management, two large-diameter pressure mains, mechanical screening, vortex degritting, pumping, power, controls and treatment-plant tie-ins. The six-page public issue confirms the major geometry but leaves the detailed bills, drawings, equipment schedules, temporary works and acceptance criteria in the controlled tender set.
