Current situation:

  • Water tankers are the most common water distribution system in rural areas due to a lack of pipe networks,
  • However, lab reports show that water from water tankers is rarely fit for consumption.

Key aims for improving tanker-based water distribution:

  • To install sensors in strategic location of the water distribution chain to ensure that water distributed from the tankers is drinkable,
  • To have solar-powered, on-board disinfection, on the water tankers,
  • To develop a low-cost integrated solution that will use less non-renewable energy and more solar powered, renewable energy.

How LOTUS will improve tanker-based water distribution:

  • The LOTUS sensors will be integrated to monitor the quality of water at the purification unit and on the tankers,
  • On the tankers, novel low-cost solar-powered water disinfection units will be installed, using the information provided by the sensors,
  • The overall system will be monitored by a central unit, which is connected to the tankers and the customers.

Outcomes of Use Case 2:

  • The system will allow the guaranteed delivery of safe drinking water without further purification, making end point purification unnecessary,
  • The tanker-based safe distribution of centrally treated water will be beneficial by providing safe and low-cost purified drinking water on the customers’ doorstep 24/7,
  • The proposed solution is easily extendable to areas affected by floods each year.
