USAID Hygiene Improvement Project E-Conference

E-conference 2006 May 12 – 22: Household Water Treatment and Storage
Household water treatment and safe storage (HWTS), together with provision of an improved water supply, adequate sanitation and hand washing promotion are highly effective interventions receiving increased attention of donors and implementers. From May 12-22, HIP held an e-conference that discussed two themes simultaneously on parallel tracks: 1) Household Water Treatment and Safe Storage: What can the poor afford? 2) How do programs promote water treatment and ensure that the government continues to supply improved drinking water sources?

    RE: Water Testing Methods

    Reid Harvey (Silver Ceramic Systems) talked about PetriFilm Plates made by 3M Company that cost ($1-2/test) and one by Hanna Instruments ($0.60/test) when purchased in bulk.

    Henk Holslag (Practica Foundation) talked about using Pathoscreen P/A pillows, a Hach Company product, to test water quality.

    Mickey Sampson (RDI Cambodia) recommended a product called easy-gel Coliscan produced by Micrology Labs, which is a simple, inexpensive ($1.35/test) test that shows presence of different bacteria through different colors.

    RE: Silver Impregnation Methods

    Reid Harvey (Silver Ceramic Systems) estimated that the cost for silver treatment to be approximately $0.10/10 L pot and $1.00/125L pot. In the first, one paints silver nitrate directly onto the interior surface of a pottery storage container and then paints salt water onto that surface. An ion exchange results in insoluble silver chloride. The second process is trickier as it requires painting the silver nitrate directly onto a pottery pot that has not been fired or fired only once and not applying too much silver nitrate solution. Then once the silver nitrate is applied, firing the pot again. This approach requires more study.
