Emergency Back-Up Pumpset for Nauru Reverse Osmosis Plant

Allflo Pumps & Equipment was engaged to deliver an emergency back-up pumping solution for the reverse osmosis (RO) desalination plant on the island of Nauru, a critical water supply servicing more than 10,000 residents.

The Challenge

The RO plant was operating with only one functional supply pump after a failure left the system without redundancy. With the remaining pump showing signs of imminent breakdown, there was a significant risk that the island could be left without access to fresh water.

The project required:

• A rapidly deployable back-up solution
• Equipment capable of handling seawater
• Reliable performance under time-critical conditions
• Immediate availability to minimise risk to water supply

The Allflo Solution

Allflo engineered and supplied a silenced diesel self-priming pumpset, purpose-built to act as an emergency back-up for the RO plant.

The solution included:

• A Remko RT-150-SS self-priming pump, manufactured in 316 stainless steel for seawater duty
• Capacity to deliver 40 L/s of seawater to the RO plant
• 400 metres of heavy-duty temporary layflat hose, supplied by Allflo
• A fully assembled pumpset with pipework and protection ramps

Critically, the selected pumpset was in stock in Australia, allowing Allflo to meet the tight delivery timeframe. The complete package was prepared and delivered to Brisbane Airport for urgent air freight to Nauru.

Outcome

The emergency pumpset was delivered on time, providing a fully operational back-up system should the remaining supply pump fail.

While the existing pump continued operating, the installation of the back-up pumpset significantly reduced the risk of water supply disruption and provided reassurance to both plant operators and residents.

This project highlights Allflo’s capability to deliver rapid, engineered pumping solutions for critical infrastructure, where reliability, speed, and performance are essential.
