Fourways Mall — 1.85 Million Litre Bulk Water Storage System
Turnkey installation of two large-capacity cylindrical tanks for Jazzman Sanitary Engineers, delivering 1,846.64 kL of effective water storage for one of South Africa's premier retail destinations.
Bulk water storage certainty for a major retail destination
Videx Storage Tanks supplied, delivered and installed two large-capacity cylindrical water storage tanks for Jazzman Sanitary Engineers at Fourways Mall in Fourways, Gauteng. The completed twin-tank installation delivers a combined effective capacity of 1,846.64 kL — approximately 1.85 million litres of dedicated bulk reserve.
Large-scale commercial developments require absolute certainty of supply to maintain life-safety compliance, absorb municipal reticulation fluctuations and keep daily retail trade uninterrupted. That made engineered water storage tanks a core part of the mall's services infrastructure rather than an afterthought.

The Challenge & Operational Context
Installing a bulk water containment system exceeding 1.8 million litres inside an active commercial hub carried critical logistical and spatial requirements.
- Accommodating two 11-metre-high vessels within tight site boundaries
- No encroachment on surrounding mall infrastructure
- Dual-vessel redundancy so one tank can be cleaned while the other stays in service
- Delivery, staging and assembly around live mall logistics corridors
- Protection against municipal reticulation fluctuations
- Life-safety compliance for a major retail destination
The Videx Solution
Videx engineered, supplied and erected two high-capacity cylindrical tanks to ASIB specification, manufactured from premium Aluzinc-coated steel in our own facility. Each 953 kL vessel was erected in roughly eight days, completing the mechanical build ahead of programme.
Tanks were outfitted with precision-located nozzles and ASIB-rated vortex inhibitors, allowing Jazzman Sanitary Engineers to tie straight into the mall's pumping grid — the same approach we apply to dedicated fire protection water storage and commercial water storage installations nationwide.
- Precision factory prefabrication of all panels and structural components
- Tight tolerances for seamless on-site bolting
- Each 953 kL vessel erected in approximately eight days
- Precision-located nozzles for immediate hydraulic tie-in
- ASIB-rated vortex inhibitors on pump suction outlets
- Mechanical build completed ahead of project deadlines
The Result & Commercial Impact
The completed Fourways Mall water storage installation provides 1,846.64 kL of certified effective storage, with full operational redundancy between the two vessels. Maintenance or cleaning can be carried out on one tank while the second keeps the mall's fire and domestic systems fully operational.
The turnkey execution demonstrates the ability to deliver large-scale engineered liquid containment that satisfies stringent engineering standards, building codes and operational demands for major commercial developments across Southern Africa.
