Project sources

City of Cape Town contract 32Q/2026/27 invites an open tender for a new 1,100 L/s Rietvlei sewage pump station constructed about 14 m below natural ground level, with a sand trap and automated mechanical screening. The issued scope adds twin approximately 1,980 m DN710 HDPE rising mains to Bellville Wastewater Treatment Works, a new 758 L/s bypass sewage pump station with mechanical screens and vortex degritters at Bellville, and a new Rietvlei administration building. Bids close at 10:00 local time on 2 November 2026; the official record names no awardee or tender value.

Project anatomy

Contract scope and delivery roles

Client / authority
City of Cape Town Water and Sanitation Directorate, Distribution Services Department
Delivery parties
Main works contractor - open tender; no awardee named, Ingerop South Africa (Pty) Ltd - tender document compiler; no construction role inferred, HDPE pipeline, excavation and dewatering, mechanical screening, pumping, electrical, controls and commissioning lower tiers - not identified
Contract route
South African Request for Bid (Open-Tender) 32Q/2026/27 under eTenders OCID ocds-9t57fa-164941. The official notice estimates a CIDB 9CE or higher grading, requires a compulsory clarification meeting at 10:00 on 4 September 2026 either at Sarepta Community Hall or online, and makes the subsequent Bellville WWTW site visit non-compulsory. The public six-page issue records a ZAR 300 document-collection fee but no tender estimate.
Execution window
The tender was published on 7 August 2026 and closes at 10:00 local time on 2 November 2026. Later delivery dates remain unconfirmed: the public eTenders record and six-page tender issue reviewed on 8 August establish no award, notice to proceed, construction start, sectional sequence, contract duration, commissioning date or operating handover date.
Works package
The confirmed package combines a deep new Rietvlei sewage pump station rated at 1,100 L/s, sand trap, automated mechanical screening, twin approximately 1,980 m DN710 HDPE rising mains to Bellville WWTW, a new 758 L/s bypass sewage pump station with mechanical screens and vortex degritters at Bellville, associated tie-ins and a new administration building at Rietvlei. The public issue does not expose the full 580-page bills, detailed drawings, temporary works, quantities, power demand, pump configuration, bypass sequence, testing schedule or acceptance criteria.
Marine interfaces
This is an inland municipal wastewater project rather than a marine outfall or coastal construction package. Its waterworks interfaces sit across deep excavation, groundwater and temporary works, large-diameter pressure conveyance, live-sewer isolation and bypass, treatment-plant hydraulic integration, screening and grit removal, electrical and control systems, commissioning and return to service. No ocean outfall, dredging, offshore installation or port scope is evidenced.
Commercial evidence boundary
The January 2026 City capital adjustments budget lists ZAR 879,340,603 as total project or programme cost and says detailed design was complete while the scope was amended for minor Bellville WWTW upgrades. The eTenders release records a zero-value field rather than a procurement value. Supplier positioning therefore depends on the controlled bills and drawings, not on converting the capital programme cost into a contract estimate.
