Improving Water Collection and Sanitation in San Pablo: Challenges and Solutions

This project addresses the water conditions in San Pablo, where we found a lack of clarity about water quality and quantity. The dry season presents challenges for agricultural water access due to abundant rain in the wet season. We initially proposed a Slow Sand Filter, but upon arrival, determined it wasn't suitable given the local conditions and available materials. We implemented a rainwater collection system, performed extensive water testing from various sources, and identified critical areas for improvement in sanitation practices. Future work will focus on boiling water effectiveness and exploring chlorination methods.

  1. Water Collection and Sanitation Katie Eng Dayton Pickering Jessica Riccio Rury Velasquez and Ian Buck

  2. Our Group

  3. Problem Statement • The conditions of the water in San Pablo are for the most part unknown • There is an abundance of rainwater in the wet season and a lack of water for agricultural purposes in the dry season

  4. Project Challenges • Our proposed problem was not realized upon arriving in San Pablo • After observing the conditions in San Pablo, we discovered that a Slow Sand Filter was not the most appropriate technology for the people here • The materials we needed were not always available • Research and communication were difficult

  5. Water Collection • Gutter system on Casa Guateca • Rainwater collection tank to be used in the kitchen area

  6. Gutter System and Tank • Designed wooden crutches to hold the gutters • Connected the downspout to the collection tank using PVC • Fixed leaks and erosion points caused by system

  7. Water Sanitation • Water sample tests from each source • Water sample tests from house drinking and tap water

  8. Water Testing from Sources • Hiked to the four sources in San Pablo to take water samples • Tested samples taken with test strips and turbid meter

  9. Water Sample Multi Meter Test Data- Sources

  10. Water Sample Coliform Test Data- Sources

  11. Water Testing from Home Sources • Took water samples from each group’s house in San Pablo • Tested water samples with test strips and turbid meter

  12. Water Sample Test Data- Houses

  13. Water Sample Coliform Test Data- Houses

  14. Future Project • Continue testing on boiling water times v. effectiveness • Come up with possible solutions for housing water sanitation • Research Chlorination techniques used and appropriateness for San Pablo
