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.

Famous quotes containing the word technology:
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
