Scenario 7-1 In Collaboration with the Ministries of Health and Water, PSI/Tanzania

Scenario 7-1
In collaboration with the Ministries of Health and Water, PSI/Tanzania launched WaterGuard, a home water purification solution, in 2002. This simple, low-cost technology enables parents to purify their families drinking water conveniently at home, regardless of whether the water was obtained through a well, community taps, or mobile water vendor. WaterGuard is manufactured in Tanzania by a well established, private-sector soap and detergent company. Each 500 ml bottle of WaterGuard treats more than fifty 20 liter jerry cans of water- enough to provide the average family with clean drinking for a month. WaterGuard is being promoted through TV and radio advertising, point of sale signs, direct marketing events, and billboards. (PSI, http://www.psi.org, January 15, 2005) .
