Our group made the appropriate calculations and developed an easily accessible rainwater catchment system that captures, filters, and distributes water that can be used by the local community. It is our goal that available rainwater can be captured efficiently and filtered sufficiently to be used for a variety of other purposes, thus providing the community with a cost effective solution to their water shortage, with the cost of the materials listed below.\n\n== Background ==\n\nThis appropriate technology project is located in the Dominican Republic in the Las Malvinas neighborhood of Santo Domingo. The team includes 3 students from Cal Poly Humboldt and 4 students from UNIBE and is taking place in the month of June, 2014. Concurrent to the project, the Humboldt State students are taking classes at UNIBE in Santo Domingo. The classes are focused on appropriate technology and engineering and are paired with one Spanish class. The system in Las Malvinas is a new rainwater catchment system which has been developed using spare parts from the [[Practivistas rainwater 2014|La Yuca System]].\n\n== Objective ==\n\nOur objective for the water project for the 2014 [[Practivistas Dominicana Program]] at the [[Las Malvinas botica popular ecoladrillo 2013|Las Malvinas pharmacy]] is to design a new catchment system using spare parts from previous systems and make non-potable water readily available for the community.\n\n== Literature Review ==\n\nHere is the [[Practivistas rainwater 2014/Literature Review|link]] for the information we collected to help us understand and review information that will allow us to build the appropriate rainwater catchment system in Las Malvinas for the 2014 practivistas dominicana program.\n\n== Location ==\n\nAn Interactive Map for Las Malvinas.\n\n{{Map\n| data = 18.513962, -69.903600 ~ Las Malvinas\n}}\n\n== Construction ==\n\n=== Pictures of Design ===\n\n<gallery title=\"Las Malvinas Pharmacy Catchment\">\nFile:Lasmalvinasgutter2014.jpg|1.

Our team re-poked small holes that were previously clogged in the first flush to make sure water was able to drain out of the system after rain. Make sure the holes are too big that the first flush doesn't fully fill up.\n\n'''Monthly'''\n\n* Clean the first flush system\n* Check for leaks\n* Make sure the roof is clean (no debris on the roof)\n\n'''Yearly/Biyearly'''\n\n* Clean the tinaco\n\n=== Steps to ensure a proper catchment system ===\n\n{{Step\n| number = 1\n| text = Set up a line to follow when setting up your gutter.
