[Case study - 53] Sanivite – Office pantry drainage without floor cutting at Saigon Tower

Key highlights

• Situation: PwC's office at Saigon Tower, Ho Chi Minh City, required a fully functional pantry for staff.
• Problem: The building's main drainage stack was too far away, and the building management prohibited any concrete floor cutting.
• Solution: The Sanivite pump by SFA Pumps Vietnam was installed under the sink to collect and transfer wastewater over 15m with a 3m height difference – no structural work required.
• Result: The pantry was completed as planned, operating reliably with zero impact on the building's structure.

In premium office buildings, expanding amenities often comes with strict technical constraints. PwC's fit-out at Saigon Tower is a case in point – and the Sanivite pump by SFA Pumps Vietnam provided the practical solution that made it possible.

The challenge

During the fit-out of their office at Saigon Tower, PwC – one of the world's leading audit and professional services firms – required a fully equipped pantry for daily staff use. Two key technical obstacles stood in the way:

• The building's main drainage stack was located too far from the planned pantry position – approximately 15m away horizontally, with a 3m height difference.
• Saigon Tower's building management did not permit concrete floor cutting to install conventional gravity-fed drainage pipework beneath the slab.

With traditional drainage methods ruled out entirely, the requirement was clear: an effective wastewater drainage solution that left the building's structure completely untouched.

The solution

SFA Pumps Vietnam recommended the Sanivite pump – a dedicated unit for collecting and transferring wastewater from pantry areas, bar counters, and kitchens in office and commercial environments.

• Compact installation directly under the sink unit – no additional footprint, no impact on the office aesthetic.
• Automatic wastewater collection and transfer over 15m horizontally and 3m vertically to the building's main drainage stack.
• No floor cutting or wall drilling required, in full compliance with Saigon Tower's building management regulations.
• Fast installation with no disruption to ongoing fit-out or building operations.

Sanivite – an under-sink grey water pump for kitchens and pantries

Sanivite is a grey water pump by SFA Pumps, designed and manufactured in France with over 60 years of engineering expertise. Installed directly under the sink, the unit features 4 inlets and can connect to a sink, washbasin, dishwasher, or washing machine. Sanivite pumps wastewater up to 5m vertically or 50m horizontally – well within the technical demands of the Saigon Tower project.

The results

Following installation of the Sanivite pump, PwC's pantry at Saigon Tower was completed in full accordance with the project requirements. The system has since operated reliably, meeting daily usage demands without any structural impact on the concrete floor.

The installation remained neat and unobtrusive – consistent with the high standards expected of a professional, premium office environment like PwC's.

Conclusion

The Saigon Tower project demonstrates that technical constraints in premium commercial buildings can be resolved without touching the building's structure. The Sanivite pump by SFA Pumps Vietnam delivered exactly what was needed: effective wastewater collection and transfer, flexible installation, and no floor cutting required.

For interior fit-out contractors and building managers looking for drainage options where no existing outlet is available nearby, Sanivite offers a proven, project-ready alternative to conventional pipework.
