About this study
Official title: ASSESSING THE IMPACT OF WATER FILTERS AND IMPROVED COOK STOVES ON DRINKING WATER QUALITY AND INDOOR AIR POLUTION: A RANDOMISED CONTROLED TRIAL IN RWANDA
DelAgua Health and Development, Manna Energy and the Rwanda Ministry of Health are collaborating on a project financed by carbon credits that will distribute household-based water filters and high-efficiency cook stoves to approximately 700,000 households in Rwanda. Prior to the full roll out of the campaign, the implementers are conducting a pilot project among 2000 households in western Rwanda. The objectives of this pilot evaluation are to document the delivery of the intervention to the intervention population, assess coverage and uptake of the intervention target households and conduct a 5-month randomised controlled trial among 500 households to assess the impact of the intervention on drinking water quality and indoor air quality.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Household drinking water filters and cookstovesBehavioural
The intervention consists of providing households with a household-based drinking water filter (Lifestraw® Family version 2.0) and high efficiency cook stoves (Eco Zoom) as well as instructions on how to use them. The intervention is delivered at community level through community health workers (CHWs). Following initial distribution of the products, CHWs visit households fortnightly to reinforce messages about correct and consistent use.
| Study group | Role | What they receive |
|---|---|---|
| Existing water management and cooking practices | No intervention | Households in the control arm continue following their existing drinking water management and cooking practices |
| Provision of water filters and improved cookstoves | Active comparator | Households in intervention arm are provided with drinking water filters and improved cook stoves Receives: Behavioral: Household drinking water filters and cookstoves |
What is being measured
The primary outcome is the main question the study is designed to answer.
Thermotolerant coliforms in household drinking water
Faecal contamination levels (thermotolerant coliforms) in household drinking water. Household drinking water quality will be monitored monthly over a 5-month period.
Measured: 5 months
Secondary outcomes (2)
Particulate matters 2.5 mg/m3 (PM2.5) concentrations
PM2.5 concentrations measured in reported main cooking area once (24-hour period) in a sub-sample of 120 households.
Measured: once
Adherence - use of water filters and cookstoves
Questionnaires, direct observations and electronic monitoring devices
Measured: 5 months
