Cullector Ultra Efficient Shower


Business potential

Every minute of every day, in hundreds of millions of homes all around the world quality fresh drinking water is being wasted due to inefficient showers.
This places unnecessary pressure on the environment, government infrastructure and household budgets.
The Opportunity
The Cullector is a proven product currently installed in over 400 homes across Australia. The Cullector is now ready to take to global markets.
Population growth and climate change add further pressure on water resources. The growth in global demand for water saving products has never been as strong as it is today and pressure will continue to mount on Governments and consumers to adopt every option available to combat this escalating problem.
Patent protection in Australia and the US offers enormous potential for secure growth.
The Cullector provides environmental and financial benefit far beyond that of the initial user and is a necessary and timely inclusion to global water conservation.

Technical summary

Of all the shower waste solutions currently on the market the Cullector is the only one that addresses all of the major waste problems inherent in typical showers.
There are approximately 900 different types of showers currently registered on the Australian Government WELS database.
Based on flow rate alone the Cullector is in the top 5% of all WELS products. When the Cullectors’ additional water saving features are taken into consideration it's clearly the standout water saving shower solution.

1. Collect It - Collect the fresh water normally wasted during warm up time.
2. Use it - Use the collected water in the shower to create a stronger fuller flow.
3. Time it - After 4 to 5 minutes a gentle pulse in the shower stream indicates time is up.
4. Pause it - Pause the shower at any time to soap up or shampoo without needing to adjust taps.
5. Low flow - Experience a quality full flow shower at low flow rates.
6. Easy DIY - Simply replace your existing shower. No drilling or plumber required.

On the surface the mechanism looks like a typical three way ball valve but the similarity ends there.
The patented internal geometry incorporates a rotatable venturi jet that diverts the fresh water normally wasted during warm up time into the attached reservoir.
Move the handle to ON and the venturi jet rotates to a position where it mixes the harvested water back into the shower stream.
Recycling ports divert a steady stream of warm water into the reservoir to raise the temperature of the harvested water. This eliminates any spike in temperature that may be felt when all of the water has been used.
The Cullector is designed to be manufactured using existing processes and technologies that have been tried and proven over many decades.
