Household Water Supply Technologies for Increasing Access to Domestic Water Supplies in Rural Bolivia

6th Rural Water Supply Network Forum 2011 Uganda

Author: Michael F. MacCarthy, James W. Buckingham, and James R. Mihelcic

 

Abstract/Summary
EMAS household water technologies have been developed in Bolivia, South America over the past three decades, and consist primarily of manual water pumps made from materials commonly available in developing countries, hybrid percussion-jetting manual drilling techniques, and rainwater harvesting systems that often use underground storage tanks. This research is believed to be the first independent field assessment that considers EMAS manual water supply technologies as well as users' perceptions of these systems and technicians' experiences with system implementation in Bolivia. Research methods consist of semi-structured interviews with technicians and other stakeholders involved in implementation of EMAS technologies, combined with household visits that include surveying and observation/inspection. Results of the investigation show use of EMAS drilling techniques to be widespread in parts of Bolivia, and prove the EMAS Pump to be an effective, low-cost/maintenance household pump.
