Brief summary describing the background
and objectives of the trial
|
In 2015, 663 million people around the world remained without sustainable access to safe drinking water (JMP, 2015). The majority of these live in rural areas with no realistic hope in the foreseeable future of access to distributed treated water systems. To combat safe water access problems especially in areas where centralized supply is expensive, the WHO advocates for simple and inexpensive approaches to treat and store water safely at the household level. Solar water disinfection (SODIS) is one such approach used to provide safe drinking water at household level.
Approved by WHO since 2005, SODIS is a household water treatment technology that uses freely available solar energy to inactivate pathogens in water stored in transparent containers placed in direct sunlight for a period of 2-6 hours or more (Dejung et al., 2007). Although SODIS has been proven to be effective, one of the most important limitations is the small batch volume of standard SODIS treated water (>3L). This often results in heavy workloads for household members to be able to disinfect sufficient volumes of water to meet drinking water needs. As such, one of the main challenges of SODIS for developing countries is to increase in a cheap and viable way the total batch volume of water to cater for standard rural household domestic requirements. This is often compounded by the limited belief that simply placing water in the sun can make water of a dirty appearance safe to consume.
The 3 year study will take place in Chikwawa District, as this has some of the worst access to safe drinking water coverage in Malawi (<50%). The study will have 2 main aims:
1. To assess the current water resource issues, governance, gender, and local water conflicts and perceptions and experiences of water interventions in the study area, and
2. To pilot a household water treatment system (HWTS) technology which combines the basic principles of both SODIS and ceramic water filtration |
