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

Page 4: KATIE ENG DAYTON PICKERING JESSICA RICCIO RURY VELASQUEZ AND IAN BUCK Water Collection and Sanitation

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

Water Collection

Gutter system on Casa Guateca

Rainwater collection tank to be used in the kitchen area

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
