Brief Summary

At least 1.8 billion people globally use a source of drinking water that is faecally contaminated and thus likely to lead to diarrheal illness: nearly 1,000 children die each day due to water and sanitation-related diarrhoeal diseases. Diseases related to the consumption of contaminated drinking-water place a major burden on human health. In 2017, 785 million people still lacked access to an improved drinking water source, and these are mostly the poor and marginalised. Almost a quarter of those people rely on surface water that is untreated and over 90% live in rural areas. Many people are forced to rely on sources that are microbiologically unsafe, leading to a higher risk of contracting waterborne diseases, including typhoid, hepatitis A and E, polio and cholera. The objectives of the SAFEWATER project is to develop technologies to provide clean water to economically deprived communities in rural Colombia and Mexico. These water technologies will be tested under real conditions with the cooperation of the rural communities. The SAFEWATER field trials aims to evaluate the health and behaviour impacts of implementing SAFEWATER water treatment technologies for drinking water disinfection, with a behavioral change intervention, within rural communities in Colombia and Mexico The project has three specific objectives:

1. 1.Assess water quality improvement at household level
2. 2.Assess behaviors and test behavioral interventions'
3. 3.Assess child growth and related health outcomes

Study Arms (2)

Intervention community

EXPERIMENTAL

Two communities in rural Colombia

Device: SAFEWATER systems for drinking water disinfection; Behavioral: Behaviour change interventions

Control community

NO INTERVENTION

One community in rural Colombia

Interventions

SAFEWATER systems for drinking water disinfection DEVICE

A domestic water purification technology, consisting of a raw water storage tank, a pump, a filtration unit (2 cartridge filters), a UVC disinfection unit (UV lamp), a storage tank for drinking water (treated and safe water), and a distribution network inside the house for drinking water.

Intervention community

Behaviour change interventions BEHAVIORAL

Targeting behaviors around the use of the technology and water more generally. Behavioral interventions will be data-driven (i.e., dependent on the problems that arise) but are likely to include household and community-level activities.
