Living Water Treatment Systems
Dr. George Greene III, P.E. and Water Missions International
A small-scale water treatment unit that can produce 10 gallons of clean water per minute.
The Living Water™ Treatment System (LWTS™) is a small-scale water treatment plant. Similarly to municipal treatment facilities in developed countries, this unit relies on filtration and chemical disinfection for production of safe drinking water. Filtration physically removes particulate and bacteriological contaminants, while chemical disinfection neutralizes any remaining pathogens and ensures the treated water is safe to drink. When operated properly, the LWTS™ will provide a community with safe drinking water for many years.

List consumables of this product (power, filters, etc.)
The system is comprised of three cages, with dimensions 122 x 102 x 117 cm, weighing 730 kg each. They are as follows:
- Cage 1 (Filtration System): Primary and secondary back-washable filters, Chlorinator with test strips for monitoring
- Cage 2 (Support Equipment): Surface or submersible pump, Operating supplies for one year, Assembly and maintenance tools, Assembly and operational manuals
- Cage 3 (Water Tank): 275-gallon storage tank for filtered water
The system can be powered with a diesel-powered generator or solar panels:
- Diesel-Powered Generator: 6 kW generators available in both 50 Hz and 60 Hz, Operating cost estimate is $2.56 per 1,000 gallons, Fuel tank and replacement fuel filters included.
- Solar Panels: Operating cost estimate is $0.16 per 1,000 gallons.
Water Missions International will train and equip local personnel to manage the LWTS after Water Missions International leaves the community.
Support and spare parts available from locally trained personnel.
System should be operational for up to 20 years. No warranty or disposal information included. Interview with representative
Each system can serve a community of about 3,000 people, treating 10 gallons/minute, up to 10,000 gallons per day. The manufactures specify that the system can be setup in less than an hour and can be operational in three hours.
The system aims to provide safe drinking water, but if the system malfunctions and one of the operations of the treatment system does not properly treat the water, the resulting water may be unsafe to drink/use.
The treatment system can be used in combination with oxidation to remove iron and manganese from boreholes.
Water Missions International publishes their research findings in journals. Papers/Posters/Presentations can be found here.
Water quality is produced to WHO bacteria removal guidelines
Water Missions International conducts routine monitoring of field activities, remote monitoring of water supply systems, evaluation of project performance data through an online management platform, and focused impact studies.
