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:
“Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power ... but also in the fact that it lacks meaning.”
—Octavio Paz (b. 1914)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
“The successor to politics will be propaganda. Propaganda, not in the sense of a message or ideology, but as the impact of the whole technology of the times.”
—Marshall McLuhan (1911–1980)
