Maturity stage TRL 9 / CRI 3-4 - Commercial Scale Up / Multiple commercial Applications

The Pump&Drink range aims at providing safe drinking water to rural communities of up to 5,000 people in emerging countries. Its design makes it durable, and sustainable and requires little maintenance. Thanks to solar panels, the water is pumped from boreholes or wells and flows through a treatment line that eliminates the particles in the water and adds a specific amount of chlorine to make the water potable. After this step, the water quality respects the WHO's bacteriological recommendations for drinking water. Then, an elevated water tank allows water distribution even after sunset or when there isn't enough sun. The distribution is made by 4 taps at ground level and 2 at a height that allows women to fill their water tank on their head, and a lighting pole gives light after the sunset. A remote monitoring system sends water production data to a cloud and gives information on maintenance needs so that local technicians can give a quick on-site response.

The Environmental Benefits

  • 1 P&D500 gives water to up to 500 people - 1 P&D2000 gives water to up to 2000 people - 1 P&D5000 gives water to up to 5000 people
  • 200 hours per day saved for women and children per community
  • 20+ years lifetime
  • No GEG’s and particles emissions during operation
  • No battery needed for the distribution as water is stored in an elevated tank
  • Increase of local agricultural production

The Financial Benefits

  • The life-cycle cost of a PV system is about 36% less expensive than the one of a diesel pumping system
  • The time saved for water collection and sickness can be used for commercial activities, for every 1$ invested in water and sanitation, there is an economic return of 3 to 34$
