A Stepped Wedge, Cluster-Randomized Trial of a Household UV-Disinfection and Safe Storage Drinking Water Intervention in Rural Baja California Sur, Mexico

Abstract: In collaboration with a local non-profit organization, this study evaluated the expansion of a program that promoted and installed Mesita Azul, an ultraviolet-disinfection system designed to treat household drinking water in rural Mexico. We conducted a 15-month, cluster-randomized stepped wedge trial by randomizing the order in which 24 communities (444 households) received the intervention. We measured primary outcomes (water contamination and diarrhea) during seven household visits. The intervention increas… Show more

“…Most households relied on springs and shallow wells for their drinking water; 20% of the study population regularly bought garrafon-bottled water (reusable 20-L narrow-necked containers, filled with treated water) from urban vendors. Locally-sourced water was commonly stored in wide-mouth containers (e.g., 200 L barrels, buckets, plastic water coolers, and tinajas e traditional clay or rock containers) (Gruber et al, 2013). Except for garrafones, and to some extent water coolers, water was typically extracted by dipping a cup into the storage container.…”

“…6,8 Hence, WASH mediations are apropos and differing, conceivably incorporating change in all angles; water access (e.g., water quality, water amount and separation to water), sanitation access (e.g., access to improved toilets, toilet support, and faecal slop 86.96% In school compound administration), and hygiene polishes (e.g., hand washing before consuming and/or after poo, water treatment, cleanser use, wearing shoes and water stockpiling practices). [9][10][11][12][13][14][15][16][17][18] For the purpose of this WASH study series, we will be discussing on assessment of water in terms of source, functionality/availability, distance and provision for drinking water in Primary schools in the Niger Delta.…”
