Thrive Water delivers water, sanitation and hygiene (WASH) services to underserved populations by pioneering scaled, evidence-based programs in partnership with government institutions, citizens’ groups, grassroots organizations and researchers.


Output-Based Aid for Accelerating Water and Sanitation Service Delivery

Thrive Water, via East Meets West (EMW) in Cambodia, Laos, and Vietnam, has executed two major grants directed at increasing improved sanitation coverage among the rural poor in Southeast Asia. Under the CHOBA I (Community Hygiene Output-Based Aid I) program in Vietnam and Cambodia, Thrive/EMW oversaw an elegant incentive-based program with targeted subsidies for the poor paid on a performance basis. This program had important direct participation from government and civil society partners and also employed a community-based incentive for the achievements of village-wide increases in sanitation coverage. The program has resulted in the purchase of more than 160,000 improved toilets by the rural poor in these two countries. The WASHOBA (Water, Sanitation, and Hygiene Output-Based Aid) Program, which includes Lao PDR as well as Cambodia and Vietnam, uses the same set of incentives for latrine delivery as well as employing the OBA approach to increase water supply system coverage, with service providers earning a per-connection payment for each new last-mile customer.

East Meets West, in partnership with the Vietnam Women’s Union, has now embarked on CHOBA II, a two-year program supported by the Bill & Melinda Gates Foundation that aims to build an additional 35,000 latrines in rural Vietnam and to turn future construction efforts from a donor-driven program into a self-sustaining commercial enterprise.

Piped Water Supply for Vietnamese Villages and Small Towns

Some 400,000 residents of Vietnamese villages and small towns are today served by 165 piped water supply systems constructed, rehabilitated, or expanded by East Meets West’s community water system program. This is one of Thrive/East Meets West’s flagship programs, with the first water supply system having been supported by EMW founder Le Ly Hayslip in 1997 in Quang Nam province outside of Da Nang, in Central Vietnam.

Integrated Deworming and Hygiene Improvement in Schools

Intestinal worms are an enormous development problem, posing not only direct health costs to children but also leading to significant secondary costs in educational attainment and socioeconomic outcomes. We are proud to be working with the Deworm the World Initiative of Evidence Action and several government agencies in Vietnam to reduce worm infection (and reinfection) among schoolchildren.  Targeting Vietnamese provinces with high infection levels, the program delivers deworming medicine to students in concert with school-based hygiene interventions intended to increase hand washing and other behaviors for minimizing exposure to soil-transmitted helminths. With support from Dubai Cares, this program is also employing a randomized experiment to identify hygiene measures with the most potential to enhance mass deworming for millions more children around the world.

Blue Planet Network

Blue Planet Network (BPN) is a membership group and funding conduit for 100+ water and sanitation service providers operating in 26 countries. Linked by a social network for sharing best practices and peer support, this community leverages $40+ million of program insights to improve water and sanitation efforts, with a focus on fostering long-term water supply and sanitation service performance. Some 1.5 million individuals are served by field programs underwritten by BPN grants.

In 2016, Blue Planet Network announced a round of funding to its members to support water system rehabilitation and expansion.  A panel of experts reviewed all submitted proposals and selected deserving projects for funding in poor rural areas, including in Nicaragua, Honduras, Haiti, Kenya and Uganda.
