This past winter break five EWB-RPI members traveled to Panama to finish implementing a water treatment system on Isla Popa II. Upon arrival, we found the previously built rainwater catchment system in disrepair, an unexpected hurdle. With the limited amount of days we had to work, we repaired the system, installed a chlorination treatment system, and educated the community on how to use the new system and about the importance of water treatment. With the coming year, we hope to wrap up this six-year project successfully with one last trip to Isla Popa II.
