Painted on the front of a bright blue shed at the primary school Escuela Taller Santa Maria Josefa Rossello in the Dominican Republic is the phrase \u201cAgua, est\u00e1 en nuestras manos.\u201d<\/p>\n

In English it means \u201cWater, it\u2019s in our hands.\u201d<\/p>\n

Providing clean drinking water for the more than 400 pre-K-8th grade students at the school has been difficult. There are two wells at Escuela Taller Santa Maria Josefa Rosello, but school officials have been purchasing bottled water\u2014a strategy that is both expensive and unsustainable long-term\u2014after there was a fear of ground water contamination on-site.<\/p>\n

Engineers Without Borders USA<\/a><\/strong> pairs individual EWB student and professional chapters with specific community engineering or infrastructure projects such as this one. The Ä¢¹½´«Ã½\u2019s EWB chapter was matched with Escuela Taller Santa Maria Josefa Rossello in 2014.<\/p>\n

During their winter break this past January, six members of the University\u2019s EWB chapter\u2014mechanical engineering majors Grace Caza \u201917, Burak Tuncer \u201917, and Fernando Suarez \u201918, biomedical engineering majors Eva Hansen \u201918 and Dilshawn Gamage \u201919, and Ab Salazar \u201919, a dual major in computer science and economics\u2014along with their professional mentor Dwight Harrienger, a Rochester-based civil engineer at the consulting firm Stantec<\/a><\/strong>, travelled to the rural community of Don Juan, where the school is located. There, they implemented a water disinfection system in preparation for supplying the school with potable water.<\/p>\n

This was the chapter\u2019s third annual trip to the site as part of a five-year commitment to design and integrate the system and educate the community about maintaining it going forward. The project gives University students the opportunity to apply the knowledge and skills they learn in the classroom to engineering problems in developing countries, and empowers the communities to sustain these systems.<\/p>\n

\u201cBeing able to build this thing we had been planning for years was very fulfilling.\u201d<\/div>\n

This third trip was a culmination of years of planning, fundraising, and developing community relations with a school 1,700 miles from Rochester.<\/p>\n

\u201cThe project involved many parts, starting here in Rochester with the planning process,\u201d says Suarez. \u201cOn this implementation trip, being able to build this thing we had been planning for years was very fulfilling.\u201d<\/p>\n

University EWB members first went to the Dominican Republic in 2015<\/a><\/strong>, when they met with community partners and conducted initial water assessments. They inventoried various local hardware stores to determine material availability and the feasibility of transporting these materials along mostly dirt roads to the school. The second assessment trip in 2016<\/a><\/strong> involved more detailed water analyses and bacterial testing. Once they gathered the data, they created three designs, and submitted these, along with the pros and cons of each, to the national EWB headquarters and to their partners in Don Juan.<\/p>\n

Although only a handful of students go on each trip, the University\u2019s EWB chapter includes many more students, all of whom assist with various aspects of the project, from designing the plans and fundraising, to creating an instructional video and manual in Spanish that explains the system for residents.<\/p>\n

COMMUNITY INVOLVEMENT<\/strong><\/p>\n

\u201cThe people in Don Juan are very friendly, warm, and receptive,\u201d Suarez says. \u201cThey didn\u2019t know us, but they received us with open arms.\u201d<\/p>\n

\u201cI had my fluid dynamics textbook from my class with Professor Aluie with me while we were doing the project because we had to do pressure loss calculations and that sort of thing.\u201d<\/div>\n

Team members stayed with host families in the rural town of Don Juan, about an hour from the country\u2019s capital of Santo Domingo, and home to approximately 9,000 people.<\/p>\n

One of the main objectives of EWB is not only to provide solutions to infrastructure and engineering problems, but to teach communities how to sustain these systems themselves.<\/p>\n

\u201cOur goal is to have the community members be completely self-sufficient,\u201d says Gamage. \u201cIf something breaks in the system, we want them to be able to fix it or to understand it enough to be able to tell us exactly what the problem is, and then we can advise them as to how to fix it.\u201d<\/p>\n

To accomplish this goal, the team organized workshops, question and answer sessions, and a tour of the structures to show parents, school staff, and community members exactly how the system worked. They showed the instructional video and left community members with a reference manual on how to monitor the system.<\/p>\n

\u201cWe realized we had to describe fully what we were doing,\u201d says Tuncer. \u201cWe couldn\u2019t just come in and say, for instance, \u2018we\u2019re going to put chlorine in the water.\u2019 We needed to describe to them why we\u2019re putting in chlorine and what it does, because if it isn\u2019t something they understand, then they\u2019re hesitant to apply this.\u201d<\/p>\n

THE WATER DISINFECTION SYSTEM<\/strong><\/p>\n

Before they could even begin designing the system or outlining strategies to purify the water, the students had to determine the exact source of contamination.<\/p>\n

After testing the water at various stages and locations throughout the school, they determined the main source of contamination was bacteria found in water stored in a rooftop \u201ctinaco\u201d\u2014a large water tank that holds the water before it is distributed throughout the building.<\/p>\n

\u201cOne thing I learned that was reiterated in school is that engineering is not an exact science… You can lay out a project on the computer and have all the exact diagrams and calculations, but then you might get there, turn on the system, and have a pipe burst.\u201d<\/div>\n

Water tests indicated that the main bacteria culprits were coliform and E. coli, which can provoke symptoms such as abdominal pain, fever, and vomiting. The team discovered the water in the tinaco contained hundreds of coliform colonies.<\/p>\n

\u201cThe problem was that the water in the tinacos is sitting water where bacteria can easily grow,\u201d Gamage says. \u201cIt was very, very high risk.\u201d<\/p>\n

They addressed the problem by thoroughly cleaning and sanitizing the tinaco, moving a jet pump from the school\u2019s library to the outside shed, and installing the new pump, chlorinator, pressure tank, and piping system. After this construction was complete, the team shock chlorinated the water disinfection system before connecting it to the school\u2019s existing water distribution system. Once the system was complete, the team waited for a time when school was not in session to disinfect and flush it using a chlorine shock.<\/p>\n

\u201cI had my fluid dynamics textbook from my class with Professor Aluie with me while we were doing the project because we had to do pressure loss calculations and that sort of thing,\u201d Tuncer says, referring to Hussein Aluie, an assistant professor of mechanical engineering in the Hajim School.<\/p>\n

In addition to drawing from their classroom knowledge, the group worked with the Rochester Water Bureau to learn, for example, how to put cement around pipes, conduct pressure testing, and properly disinfect a well and plumbing system. They also had help from community mentors, including Harrienger, who assisted the students in evaluating options, designing systems, and integrating improvements.<\/p>\n

\u201cThe role is different than at work, where I\u2019d be in more of a project manager role, which is more directive,\u201d Harrienger says. \u201cHere the goal is to let the students expand their level of comfort with decision making and responding to project challenges.\u201d<\/p>\n

The team also had to be conscious of only purchasing materials that could be found in or near Don Juan, part of a commitment to support local businesses and ensure that community members have available materials.<\/p>\n

\u201cA big part of EWB and what we do is sustainability,\u201d Tuncer says. \u201cEven though we facilitate this project for the community, it\u2019s important that they know what we do, and how to maintain and operate it. All the materials we use in the project have to be locally purchased so they can be replaced locally if anything goes wrong.\u201d<\/p>\n

There were other challenges, such as working around government-mandated routine power outages that shut off electricity in various regions, for hours or even days at a time. On these days, they often worked late into the evenings, sometimes until midnight or into the early morning hours, relying on lanterns.<\/p>\n

\u201cIt was tough to deal with the ambiguities that come with doing projects in developing countries,\u201d Salazar says.<\/p>\n

\u201cOne thing I learned that was reiterated in school is that engineering is not an exact science,\u201d Gamage says. \u201cIt\u2019s a lot of troubleshooting and figuring out things on the fly. You can lay out a project on the computer and have all the exact diagrams and calculations, but then you might get there, turn on the system, and have a pipe burst. I learned how to deal creatively with problems in that sense.\u201d<\/p>\n

The project cost approximately $4,000, excluding travel expenses. University students funded travel and supply costs with University support including a Hajim grant, USEED crowdfunding<\/a><\/strong>, independent donations from individuals and local companies such as KodakAlaris, and various campus fundraisers including dinners and dances.<\/p>\n

A group of students from the University\u2019s EWB chapter will return to Escuela Taller Santa Maria Josefa Rossello in January 2018 for their first of two monitoring trips. As Eva Hansen explains, they\u2019ll do things such as \u201chelp the community understand the necessity of repairing dead ends in the system, such as broken toilets and sinks,\u201d thus reducing the opportunities for bacterial growth.<\/p>\n

HEADING HOME<\/strong><\/p>\n

The bright blue shed at Escuela Taller Santa Maria Josefa Rossello now houses portions of the new water disinfection system. The murals that decorate its walls were part of a community engagement activity in which several school students, the EWB team, and community members put their painted handprints above the quote \u201cAgua, est\u00e1 en esta en nuestras manos.\u201d<\/p>\n

On the last day before the EWB members left the Dominican Republic to head back to Rochester, the school thanked the team for their hard work and continued dedication to the project during a morning ceremony.<\/p>\n

One of the young students, in practiced English, stood in front of the group to give a speech.<\/p>\n

Grace Caza says the student\u2019s words \u201cbrought tears to my eyes.\u201d<\/p>\n

\u201cThis project is something I\u2019ve been working on since I was a freshman. It\u2019s not something where you expect a thank you, or expect recognition. It\u2019s something you do because it\u2019s a learning experience and you\u2019re doing something to make a difference in someone else\u2019s life. EWB is where I found a sense of community on campus, so going on this trip, building this, and seeing the community come together and understand the whole system was incredibly moving.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
