1.1 Site Background & DescriptionLas Delicias is a community of about 600 homes and 3000 people situated on the western slopes of Volcan San Salvador about 15 miles northwest of San Salvador, the capital of El Salvador. The community is fairly sparse and anticipates growth to over 1000 families over the next 20 years. The communities residents suffer from lack of employment, but over recent years several NGOs have begun making improvements within the community that are improving living conditions, health, and education.The residences of Las Delicias are Latin American and mostly agricultural. Some are Indigenous. The Village of Las Delicias was disrupted during the civil war, as were many villages, there is no real governmental involvement. There is some military and police presence. Most community event planning is done through the parish council. Unemployment is very high. Those who are employed work in garment factories or agricultural labor. The average income is around $10 a week. Most people are Catholic.Las Delicias has a water supply system that was installed about 20 years ago. This system includes buried piping to individual households, three storage tanks at upper elevations in the community, over 150 valves to control distribution, a well at a lower elevation in the community and a pumping station with two pumps: (1) submersible pump in the well and (2) transfer pump for delivering water to two of the storage tanks. The three storage tanks all receive water by gravity from a spring located several kilometers away on the mountain and two of the storage tanks receive water from the well. The well pump and transfer pump operate about 4-6 hours per day. Water flows by gravity from the tanks to individual households. The valves throughout the community are operated manually by a single operator who walks throughout the community controlling which zones have running water at various times during the day. However due to topology and limitations of the piping system design, the water supply to individual households varies considerably. Some homes receive water almost every day whereas other homes reportedly receive water less than once per week. A culture of scarcity exists in the community so that when the water is running, residents collect water into many available containers so that they will continue to have water until the next time the water is running.1.2 History of Prior Activities At The SiteEWB/MAP was originally contacted by Dave Haeussler, who gave a presentation regarding this project. Dave became involved with the NGO (Project FIAT). He has been working in the community for some time building clinics, roads and dwellings, through his local church in Philadelphia. While working in the community, Dave became aware of an ongoing health problem stemming from scarcity of clean potable water. There is an existing system that pumps water from a well to holding tanks which in turn supply water through a gravity piping distribution system to approximately 500 homes. The supply is sporadic and the cost of pumping prohibitive to the community. Project FIAT recognized the problem and realized that engineering expertise was required to develop solutions. After Dave made his presentation to EWB/MAP we decided to help and submitted the project application which was approved. In 2010 we went on the first assessment trip, tested the existing system, analyzed water samples, and performed a heath survey. The existing system includes a well pump, a booster pump, holding cistern, piping to three storage tanks and a gravity piping distribution system to approximately 500 homes. It has been found that the system generally operates as designed but has some basic deficiencies making it expensive to operate and making water distribution inequitable. The main issue is pumping cost. The residents simply cannot afford it. The way the system operates, all water is pumped to high elevation and then gravity-distributed to the village. If about 50% of water as pumped to an intermediate elevation so serve half of the village located below this elevation, one could save about 30% of the pumping cost or, conversely, supply 30% more water for the current pumping cost. The analyzed well water samples were clean. The issue is the method residents use to store water. Since the water is available for only about four hours per day, the residents store it in all variety of containers for later use. This may contribute to the presence of Dengue fever and to the fact that over 80% of children in the village are infected with parasites (although other causes, such as walking barefoot, are possible). After the first assessment trip we concluded that there are two ways to reduce pumping cost: (a) drill a new well at a higher elevation, (b) add an additional tank at an intermediate elevation. In November of 2012 we went on the second assessment trip. We concluded that the most viable solution is to add another tank at an intermediate elevation and a new dedicated pump to pump about 50% of water to the new tank. We identified the location of the new tank and the necessary tie-in points to the existing water supply and distribution system. We established new contacts, including with office of the Mayor of San Juan Opico, the local public health representative, and engineers working with the local Rotary Club. 1.3 Contractors And Other PartiesWe will do the new tank construction with the help of the local villagers supervised by a local engineer working with Rotary Club – Daniel Rivera Campos. We will have two EWB-MAP people on the ground at all times to coordinate the efforts. We will be driven to the site by drivers from Project FIAT. We will work with the local Water Committee (ADESCO).
