Summary

Purpose statement

The Pump and Associated Structures Subteam of the Mali Water and Disabilities Study aims to enhance the ability of disabled people to obtain water. Toward this end, this subteam concentrates on designing and implementing modifications and enhancements to existing water pumps and associated structures.

Goals

  • To improve existing water pumps and associated structures to ensure their accessibility and ease of use by disabled people.
  • To create modified blueprints for the existing pump superstructures, which include a seat, additional foot traction, an entrance ramp, and widened entranceways for tricycle access.
  • To create more ergonomic handle extensions for shallow water table pumps which will allow users to pump from a more efficient orientation.
  • Create a Phase 2 outline as well as concluding our research from Phase 1.
  • Create a stress analysis for and build a virtual model of the India Mark II Pump.
  • Finish statistical analysis of time lapse photography from previous site team trips

History

  • The Pumps and Associated Structures Subteam was formed in Fall 2006 as part of the Mali Water and Disabilities Study.
  • We work closely with World Vision, also known as WAWI or West Africa Water Initiative, and with Handicap International.
  • Our support comes from donations to the Collaboratory and grants from the Conrad Hilton Foundation.

Site Team Trips

Summer 2007 Site Team Trip

Students Kay See Tan and Stevie Baum implemented the groundwork for building relationships and demonstrating the difficulties faced by handicapped users with the pump.

  • Founded initial research and created Survey for handicap types with disabilities in Tominion and San Regions
  • Created relations with many handicapped clients and also with World Vision Mali
  • Addressed problems with World Vision Pump Superstructure
  • took part in survey results discussion conference

January 2008 Site Team Trip

Students Emily Howell and Jim Davis served with adviser Dr. Ray Norman

  • Began testing new seat and step designs and gathered data on pump usage
  • Received data to help complete new pump superstructure blueprints

Summer 2008 Site Team Trip

Student Adam Lenon aided alongside Dr. Ray Norman, Dr. Barbara Ressler, and Dr. Lamar Widmer in trip research.

  • Began time lapse photography testing on different well environments
  • Started construction on Madiakui test site
  • Designs reassessed for seat and steps
Construction of the revised pump superstructure in Manidiakuy, January 2009

January 2009 Site Team Trip

Students Sarah Jarnecki, Elizabeth Sussman, and Zachary Crane worked with adviser Dr. Norman on this site team to help culminate the years of research as Phase 1 came to an end. The J09 trip was one of our last opportunities to have a site team test our designs.

  • A major oversight was found in the pump superstructure that was addressed in future blueprints.
  • After series of three incorrect wells built, the final pump superstructure was created with a seat, ramps, and a new dimensional layout. :*Continued time lapse photography in new geographical areas such as Koro

Summer 2009 Site Team Trip

Advisors Dr. Barbara Ressler and Dr. Ray Norman

  • Final pump superstructure design implemented (old seat removed and side seat created)
  • Testing of new handle prototype implemented
  • Time lapse photography testing continued
  • New project areas found in Ghana and Niger visits
