Since 2005, we have helped to make improvements to two potable water systems in Ecuador, the Panecillo regional system serving five communities, and the La Banda system serving one community.  Collaborating with The Traveling School and Deer Hill Expeditions, we helped to replace inadequate water pipes with larger pipes so that all homes in the communities of Agualongo and San Juan Loma could receive running water.  Visiting student groups worked in mingas with local community members to install the new pipes.  We also coordinated the purchase of a chlorine machine for the Panecillo regional potable water system with donations collected by a Traveling School alumna.  This machine separates salt, creating a highly chlorinated solution that is used to treat the water for the five communities regularly.  In 2012, with the help of an Alternative Spring Break group from Northeastern University, we built a retaining wall to protect a spring that is one of two water sources for this system.  In 2010, working with an Alternative Spring Break group from Northeastern University and the community of La Banda, we built a water filtration tank that settles sediment out of the water before it is delivered to homes in La Banda.
