Technology
With a philosophy of keeping its clean-water systems 'simple and affordable' LWW developed community-sized water treatment systems using proven technology for treating contaminated water. To promote long-term sustainability of the systems, every effort is made to use parts that are available in-country where LWW systems are active.
The standard LWW water treatment system is a batch treatment process with an integrated water bottling station for distribution of bottled water throughout a community. The process capacity for a single batch is approximately 300 gallons of treated water per cycle, with a processing time of about one hour.
Processing consists of three stages of filtration, followed by ozone or UV (ultra-violet) light disinfection to eliminate bacteriological contamination. The equipment cost for a standard LWW system is $3300, and operating costs are pennies per US gallon treated, excluding labor costs.
In addition to community-sized water treatment systems, LWW has also developed single-family systems for use in areas such as Appalachia where coal mining may have contaminated ground water sources.
