Visit here to see what S&T has to say about what our teams have been working on the past few months!
The Kansas City Professional Chapter of Engineers Without Borders is hosting an annual fundraiser volleyball tournament “Sandtastic” on Aug 24th in Shawnee, Kansas. We are looking to send a team, which half to the team entry cost will be covered. The link for more information is here.
Our students put in incredible amounts of time and effort to make our projects successful, but without funding it’s hard to make it happen. Visit the link below or text NoBorders1 to 71777 to donate now. All money raised will go towards our Montana Cahill Challenge Grant and will be matched 1:1.
The EWB Faculty and Staff Talent Show is back! This is a great way for our students, faculty, and community to share a fun night and learn some of the lesser known skills at our university.
On January 3rd-11th, the Ecuador team took their first ever assessment trip to the community of Agua Fria. The purpose of the trip was to find out what the community wanted from a water system, their capacity to maintain it, and technical data on where the team could get water from. The students and mentors collected data on water quality and quantity at all nearby water sources, conducted community interviews, held community meetings, and did a topographical survey to find elevation differences within the community. The river, which is the community’s main source of water, is contaminated by both total coliforms and E. Coli, a bacteria that can cause illness when ingested. The team did an educational program at the community meeting and for the children at the community school to show that the river water is contaminated and what they can do to treat it. The team will use the data collected on this trip to design the first phase of the project, and hopes to travel again in August for implementation.

This summer a team of eight students and two mentors traveled to Puerto Pando, Bolivia to implement the second phase of the water distribution system. A surveying team began to survey from the current dam and worked towards the storage tank. A wooden stake was hammered into the ground as a temporary benchmark to survey the construction site day to day without having to start from the dam. After tank locations were chosen based off previously calculated elevations, clearing and digging began for the sedimentation tank and slow sand filter.
The collection dam was constructed using concrete and two small pieces of plywood as forms. The forms were laced together using tie wire and wooden “ribs”. Six pieces of rebar were keyed into the surrounding clay and into the concrete to help hold the dam in place.
The sedimentation tank was rectangular in geometry and utilized wood framing for all concrete pours. Plywood and locally available lumber and bamboo was used to create the forms. Once the concrete cured for long enough, the forms were taken off and work began to install the flow control device, baffle, and effluent launderer. The plywood was not thick enough to sufficiently support the concrete, leaving the walls bowed. The tank also experienced leaks, which the community plans to fix using the same type of mortar as for the slow sand filter.
The slow sand filter was a tall, cylindrical structure. Rather than using wooded forms, the rebar was wrapped in two layers of wire mesh and then mortar was plastered on. The plaster had to be applied one layer at a time, giving the previous layer at least one night to cure before adding the next layer. To accommodate the 3+ meters of height, scaffolding was erected around the perimeter of the structure. It is up to the discretion of the community members whether they want to leave the scaffolding up or take it down until maintenance is needed.
There is also a bypass system which the community still needs to install. This will allow the community to direct water around one or both of the structures for any reason they need to. Once the community finishes the last few construction steps, the water project will be considered complete and EWB-S&T will move into the monitoring phase.
This summer 6 students and 1 mentor from EWB-S&T returned to Erquiz Oropeza (10 de Abril) to assess the current situation in community and gather more data. The team conducted a topographical survey, taking over 900 points, to gather pertinent data needed to design a water system in the community. EWB-S&T also took many pictures and gathered information about the serious erosion problems in the community. Over the school year the community had implemented two water tanks and a basic distribution system. While there the team connected a third tank to the system and changed out some of the HDPE pipeline for PVC.
EWB-S&T also received the electrical resistivity test report from COFADENA and met with them to discuss the possible location and drilling of a well in the community. The team met with the San Lorenzo Municipality to discuss political matters about land rights. Hopefully this will allow for a continued relationship with the municipality.
Overall, the trip went smoothly and both returning and new students learned valuable information about 10 de Abril. EWB-S&T is excited to begin designing a water system and erosion control solutions for the community.
After a summer full of hard work and preparation, our Puerto Pando team is ready to travel in just a few weeks! Sarah Smedley, the program lead, let us know what will be going on during their trip.
“We will be making our journey to Puerto Pando, Bolivia on August 4th and will return on August 18th. While in Puerto Pando, the team and community will be working together to implement the second phase of our project: a sedimentation tank and slow sand filter. This will provide the community with water to drink and carry out their everyday tasks like cooking, laundry, and washing. We would greatly appreciate your thoughts and support as we step into this amazing journey.”
