Water Filter Study in Ciudad Victoria

Evaluating Comparative Efficacy of Sawyer PointOne Filter Types in Ciudad Victoria, Mexico

This study measures effects of water filters and filter types on household health in Ciudad Victoria, Mexico.

Study Overview

• Status: Enrolling by invitation
• Conditions: Diarrhea; Waterborne Diseases
• Intervention / Treatment: Device: Bottle Filter; Device: Bucket Filter; Device: Tap Filter

Detailed Description

A project to assess the water quality in Ciudad Victoria, Mexico and the effectiveness of different Sawyer PointOne Filter types (Bucket, Tap, Squeeze) . The project is designed to 1) assess the impact of filters on health and well-being of families, 2) assess the impact of filters on the economic status of families and 3) compare different filter formats for use/adoption on the above metrics. The project will provide information about how well the different filters are working in urban households in a middle-income Latin American country, make recommendations for future deployment of filter types in similar settings, and determine the potential for scaling the use of filter systems to provide clean drinking water for people in need in future projects.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Bottle Filter Arm; Receive a filter which attaches to a bottle. If the household does not have an eligible tap, they are randomly assigned to either this arm or the Bucket Filter Arm.	Device: Bottle Filter; The household is given a Sawyer Squeeze Water Filtration System.
Experimental: Bucket Filter Arm; Receive a filter which attaches to a bucket. If the household does not have an eligible tap, they are randomly assigned to either this arm or the Bottle Filter Arm.	Device: Bucket Filter; The household is given a Sawyer International Bucket System, which is a Squeeze Water Filtration System that is integrated with a hose and bucket.
Experimental: Tap Filter Arm; All households with an eligible tap (compatible with filter and runs) will receive a tap filter.	Device: Tap Filter; The household is given a Sawyer Tap Water Filtration System.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in self-reported diarrhea rates from initial filter distribution to end of follow up	Self-reported diarrhea rates in households surveyed at distribution of the water filter and at each follow up visit.	3 months follow up

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in other self-reported health outcomes from distribution to end of follow up	Other health outcomes related to waterborne illness (such as fever, vomiting, muscle aches, rashes, etc.) which are also self-reported in the household surveys.	3 months follow up
Change in household economic outcomes from distribution to end of follow up	Household economic outcomes related to costs of water and waterborne illnesses (such as money spent on water, money spent on medical costs, days of work missed due to diarrhea, etc.) which are also self-reported in the household surveys.	3 months of follow up
