Spring Protection & Water System Project Terreritos, Honduras Project Report as of November 2006 PENN | EWB EWB – USA www.seas.upenn.edu/~pennewb www.ewb-usa.org Context - PennEWB Mission and Purpose Mirroring EWB-USA's mission, PennEWB's seeks to partner with developing communities worldwide to improve their quality of life through implementation of environmentally, socially, and economically sustainable engineering projects, while also developing internationally responsible students and professionals. PennEWB seeks to collaborate with communities to find solutions that address the roots of any challenges preventing residents from achieving a baseline standard of living. PennEWB projects can involve the design and construction of water, sanitation, energy, education, and shelter systems. These projects are initiated by, and completed with, contributions from the host community, which is trained to operate the systems without external assistance. In this way, PennEWB ensures that its projects are appropriate and self-sustaining. The projects are conducted by groups of students under the guidance of faculty and professional engineers from partner engineering firms. PennEWB is dedicated to giving Penn students the opportunity to reach out to developing communities and to their own backyard. Our foreign involvement is a mutually beneficial process. The partner community is provided with needed assistance to improve quality of life and plan for their future. Students are exposed to new cultures, obtain experience planning and implementing an engineering project, and are made aware of outstanding engineering challenges in developing communities. PennEWB's local projects fulfill a similar role. Locally, we work with area high schools and other Penn student organizations to complete educational and outreach initiatives related to sustainable engineering and sustainable development. Project Background Location Village of Terreritos, Municipality of Nueva Frontera, Department of Santa Barbara, Honduras. Problem Identified and History Terreritos (“little piece of earth”), Honduras is amongst the poorest communities in the Municipality of Nueva Frontera within a country that is one of the three poorest nations in the western hemisphere. A growing farming village home to 225 inhabitants, one third of the houses in Terreritos were not connected to a running water supply in early 2006, and most of those that were did not receive an adequate amount of water. This condition has been the norm over the past several years, and has resulted in a lower quality of life than warranted, inadequate sanitation, and health problems such as a skin condition that affects many of the children in the community. The dry seasons during the summer have been especially hard on the villagers of Terreritos. At the time of the community’s founding, residents extracted water from small wells nearby. This solution supplied water to the initial twenty-five households, but it became clear that this would not be a sustainable source as the community grew. In 1995 water was routed from a water spring providing 2.5 gallons per minutes about two kilometres away through a distribution tank and on to the existing houses. Within a decade however, this system was proving insufficient for the 46 current households. In response, the community purchased land containing a water spring located about five kilometres from the village, estimated to provide eight gallons of water per minute. When added to the existing water supply, the new source will provide the community with sufficient water to meet PENN | EWB EWB – USA www.seas.upenn.edu/~pennewb www.ewb-usa.org current needs as well as ample surplus for the projected future growth of the community. The community needed assistance to complete a distribution system from this new source. Working in partnership with a local non-governmental organization, FUCOHSO, PennEWB commenced work with Terreritos in the fall of 2005 to make the system a reality.

Water System Follow-up and Latrine Assessment On-Site Team Nicholas Blanchet, Thomas Macrina, Priscilla Matos, Hong Truong, Tony Sauder Local Participants The villagers of Terreritos; FUCOHSO, a Sustainable Harvest International regional nonprofit Project Progression Initial Steps and Research Phase In February 2004, PennEWB founder Arthur Chan initiated contact with FUCOHSO, a Honduran non-profit devoted to providing small agricultural communities with the resources to adopt sustainable farming practices. He learned of the existence of an existing partnership between FUCOHSO and EWB-USA and learned of the needs of several communities for an improved water supply. For the next year, PennEWB members conducted research into the available options for a sustainable water transportation, storage, and distribution system and continued the work of establishing EWB as a permanent student organization. In the Fall of 2005 direct communication was established between PennEWB and Terreritos in preparation for a site assessment visit. Also in preparation for this trip, preliminary design plans were submitted to and approved by the technical advisory committee of EWB-USA, a group of 30 professionals involved in engineering, sustainable development, and other areas of expertise relevant to the project. Site Assessment Trip Dates: January 12-17, 2006 Accomplishments: - Identified and corrected flaws in mapping data provided by SANAA, the Honduran PENN | EWB EWB – USA www.seas.upenn.edu/~pennewb www.ewb-usa.org national water authority –Assessed local suppliers of necessary building materials –Established a strong working relationship with community leaders –Conducted a baseline health and community needs assessment –Carried out preliminary water purity testing, revealing that the village’s existing water supply may be contaminated with bacteria and pesticides from nearby coffee fields Implementation Trip Dates: May 6-20, 2006 Accomplishments: - Excavated spring source and built protection system - Constructed collection tank at beginning of pipeline - Reassessed pipeline path - Laid Pipe and dug trench at early stage of pipeline - Installed supports at ravine crossings - Participated in community events including weekly soccer match, mother’s day celebration, and church services - Provided health education skits for children Water System Follow-up and Latrine Assessment Dates: October 20-25, 2006 Accomplishments: - Reviewed pipeline completed over the summer by the community and measured 4x increase in water flow due to the new system Assessed new storage tank location and requirements for new pipes to households. - Conducted focus groups to assess community needs and effects of Phase I of system; learned of perceived decrease in diarrhea and scabbies due to increased water supply - Assessed future community needs, sanitary practices, and evaluated the feasibility of helping the community expand the availability of pit latrines - Conducted second round of water purity testing - Discussed at community meetings the tasks necessary for maintenance of the system including regular cleaning of the collection and distribution tanks, routine checking of vulnerable points such as ravine crossings, and installation of additional pressure release valves. System Components Schematic Diagram of Water Distribution: PENN | EWB EWB – USA www.seas.upenn.edu/~pennewb www.ewb-usa.org Spring Protection and Collection Box In order to minimize infiltration of groundwater at the source, the area around the spring eyes was excavated and a spring protection structure was erected above it. Earthwork to divert surface water was placed above this to minimize soil erosion and prevent contamination from run-off. Water emerging from each side of the Spring Box was routed through a concrete collection box and into the pipeline. Pipeline Primarily used buried 1½ inch PVC. Galvanized steel piping used for areas where trenching was impractical. Corrections to the original SANAA survey were made by members of the May implementation team and by GeoConsult, a local surveying company o The section north of the main road (red and white dotted line) is ~1,300m in length and represents the most challenging section of pipeline o 3 deep ravine crossings requiring galvanized pipe with reinforced concrete end supports The ~3,700m section south of the main road follows along a smaller dirt road. o more straightforward section of pipeline o Mostly buried PVC with small gully crossings that may require some galvanized pipe Ravine Crossings At several locations along the pipeline the sloped and rocky nature of the terrain is not suitable for buried PVC. At these points galvanized pipe crossings held at each end by reinforced concrete supports. Distribution Tank The October follow-up team helped determine the location for a new water distribution tank to be constructed by residents with funding and design support from PennEWB. The new tank can be placed at a higher elevation than the existing tank, and this combined with the greater rate of flow from the new spring will allow the community to provide water to several households disconnected from or underserved by the old system. In the meantime, water from both the old and new spring source has been routed through the existing tank. PENN | EWB EWB – USA www.seas.upenn.edu/~pennewb www.ewb-usa.org Team Accommodations and Logistics While in Terreritos, the assessment and implementation project teams stayed at a FUCOHSO agricultural training camp located about a half a kilometer from the center of the community, as well as in the homes of villagers. Though still partially under construction, the FUCOHSO facility allowed the team to live together as a group in close proximity to the community. Three students were offered housing by host families in the village. During implementation, as dictated by the project agreement, the first week of meals were provided by the community and purchased at cost for the remainder of the trip. Cooking was provided by volunteers in the community at the camp every morning and evening. During the day community food was brought to the worksite. Staple items included beans, corn tortillas, chicken, fried plantains, and coffee. Throughout the trip bottled water was purchased for drinking and all students had water purification tablets. Limited spring water was brought to the camp for washing and a small spring near the camp provided a convenient location for bathing. Relationship with Terreritos Working with the residents of Terreritos is a very rewarding experience, and we feel that at each step of the project they have contributed resources and effort to the maximum extent of their ability before requesting assistance from EWB. Coordination of work on the water system was arranged through the local patronato system, the village’s democratic system of governance. Mauricio, elected leader of this group, served as our primary contact in the village and coordinated mandatory work contributions and a monthly usage fee of twenty lempiras from each family who will benefit from the completed system. During both the assessment and implementation trips, community meetings were held at the local schoolhouse, the largest structure in the community, in order to allow for input from all interested community members in the planning. Arrangements for the future management of the water project have been made and a water board has been established to oversee collection of dues and the execution of regular maintenance.
