Spring 2016
Meeting Minutes (01/31/16):
Today, we have finally decided that we will be working on building the tank this summer since we still don’t have sufficient data for the pipeline. For fundraising, we may need to start asking our relatives and communities for donations. There will be a personal contribution requirement of $500. An email for grant applications will be sent out.
For project fundraising, we will be setting up a Panda Express on Thursday the 18th. We will need to flier. We are hoping to raise enough money through fundraising for one full ticket.
For next week, everyone should try to get two articles with brief descriptions from the Literature Review Google Drive. We will be starting preliminary ideas for the tank so everyone should have ideas.
Fall 2015
Meeting Minutes (11/21/15):
Today, we decided not to do the pizza fundraiser this semester since the date coincided with midnight breakfast. We decided to do the Panda fundraiser on the last week of class on December 3rd; a spreadsheet will be sent out to sign up for giving out fliers.
Our advisor doesn’t like the idea of building the tank first this summer; he suggested doing the pipeline, but we might not have the information to build that this summer. The water tank should fit the peak time of the year and be big enough to always have water. We need to perform a cost analysis of the 3 day tank versus the 1 day tank. We also need to keep in mind the fact that the community has grown. For water treatment, we’ll have either sodium or calcium hypochlorite tanks. We’ll use a pressurized tank instead of a pump system. There needs to be a smaller tank on the side where people live so that water can get to homes.
If you want to take a class where you can work on designing the DEID project, you can take CE 314. Travel team applications will be sent out after exams to be filled out over winter break. Interviews will be set up afterwards.
Meeting Minutes (11/14/15):
Today, we further discussed fundraising for this semester. We are still planning to sell pizza to people coming back from Shooter’s, as well as fundraising through Panda Express. We will likely sell pizza on December 2nd and sit at East bus stop with the pizza and a card reader. Having two one hour shifts (12-1am and 1-2am) is probably ideal.
As for the project itself, the application for a grant from UC Berkeley has been submitted. We are still waiting on a meeting with Shazad to move forward with the design, although it is moving forward nicely.
Meeting Minutes (11/7/15):
First of all, we discussed possible fundraised ideas. After voting, we decided that we’d definitely sell pizza at the East campus bus stop to students coming back from Shooters. We’ll also organize a Panda Express fundraiser.
One of our potential issues is that we don’t have a soil sample for analysis from the site where the tank will be set up. Once we find out from the professor whether this sample is necessary, we’ll decide whether to figure out how to get the sample sent here or to put off building the tank for next summer. We also need to decide whether to use PVC or galvanized iron pipes. PVC pipes cause pressure to be lost, which means that we won’t reach all the houses. We also discussed creating a STEM workshop with high school students in the town.
The bulk of the meeting was spent discussing the pros and cons of different tank sizes. The tank can be built for 1 day storage, 2 day storage, or 3 day storage. While a smaller tank means less materials, money, and labor, it also means less emergency storage, and the sediment accumulated inside the tank would need to be cleaned more often. A larger tank would mean more storage for the expanding population of the town, and less variable chemical concentration for the water treatment. However, it would make it more difficult to deal with water contamination, and lead to more sediments to clean. It’s unclear which tank size would require more maintenance overall.
Meeting Minutes (10/31/2015):
Today, we discussed the possibility of a training program for children in the town of El Pital. We suggested ideas such as workshops and competitions to train the children to maintain the infrastructure we will be building. Fundraising may also possibly happen this semester. Working with companies like Panda Express or Red Mango would be easy to organize.
We also discussed DEID Honduras’s entering into a grant competition called “Big Ideas” hosted by Berkeley. We want to stress our innovation in being collaborative with the community itself to help maintain the water systems we will be building over the long term.
As for the design itself, it has started to come together. The main concern is creating a basic tank design in order to build a rough budget needed. We discussed the need to consider break pressures, which are contraptions placed every 100 meters or so that will allow the water to return to atmospheric pressure. We will also need to figure out how much water storage is wanted by the community. Finally, we discussed the location of the tank. We would like it to be at a high altitude to maintain water pressure.
Meeting Minutes (10/17/2015):
We talked about scheduling appointments with the advising professor. We also discussed the following fundraiser ideas- Krispy Kreme, pizza, renting students to teachers, and a Super Smash Bros tournament. At the moment, we’re favoring the Krispy Kreme fundraiser and the Wii tournament, although we’ll have to wait for codes from the professor in order to start organizing the fundraiser
We discussed our topics of research. We went over guidelines on how to cross a river without a bridge, keeping in mind that we wouldn’t have the resources to dig underneath the river. We also discussed how galvanized pipes, unlike PVC pipes, come with the risk of corrosion in water, which could trap lead present in the water. It’s most likely that the project will end up using PVC piping. With respect to water filtration, we discussed two types of filters- ceramic water filters and biosand filters. The water doesn’t need to be filtered to drinking quality; it only needs to be clean enough for showering.
We agreed to post all our research notes and links onto the Google drive for everyone to access.
Meeting Minutes (10/3/2015):
Today, we went over a basic outline of what we will be doing for the project going forward. If you haven’t already, go to www.dukegroups.com, search for DEID, and add yourself to the group.
We reviewed the research document concerning the project in El Pital. The water source has been confirmed to be in a national park in order to prevent contamination from deforestation or other activities that could potentially cause contamination. The fourth design in the document has been decided upon, although the water usage amount may need to be looked at again. We will also be working closer with Project HEAL this year and within the next few weeks, we will have a Skype call with the water board in the village.
We also gave each member a topic to research over the next few weeks. If you missed this meeting, pick one to look over. The topics are water filtration, damming effects, effects on ecosystem, crossing the river with pipeline, tank material, and PVC vs. iron piping.

- Sign up for tabling on Tues/Thurs on Google spreadsheet
- Flyers for East, posters on West
- Design – Meeting with Ross
- Filtering through a layer of topsoil/mulch will be doing most of removal
- Need to have a constant slope for water to flow in pipes
- 1.5-2 inch pipes suggested so that particles are not clogging pipes or collecting on the bottom
- Could have a holding tank (but wouldn’t want water to sit longer than 24 hours) incase only one house was using water, with valve that opens once there is a certain volume of water
- Better to be discharged into soil rather than straight into the river
- Will need spreading system at end to reduce pressure of water coming into filter system
- Can be as simple as a bucket with holes in it
- Food scraps wouldn’t necessarily be a detriment but may clog system
- Could use barriers where water flows in the middle (dense particles sink to bottom, light particles remain on top)
- Sand on bottom, gravel, and then mulch layer on top
- As long as water is being absorbed by soil, not much of environmental issue
Meeting Minutes 2/8/15
- Daniela came into talk about filtration
- Plate settler system
- Needs slow flow rate
- Water slowed down by plates (heavy particles fall onto plates and collect on bottom)

- Has had some bad publicity due to isolated incidents, but Elly has not seen any worsening of safety conditions
- Considering traveling in June
- Grants
- Plan to come next week with an outline of research topic and possible grants
Meeting Minutes 2/1/15
- Call with Elly Goetz
- Former DEID student coming in next week and Environmental Engineering graduate student coming in the week after to talk about design for filtration
- Sketch: preliminary design to determine costs
- Main part of community has two sides
- River side: water that sometimes go straight into the river; main issue is river contamination
- Hill side: a few of the homes have their water piped underground to the river & rest of water gets dumped onto the road which sits on the side of the street; main issue is sanitation
- Main part of community has two sides
- Type of graywater: bathing water, largely water from washing clothes and dishes (minimal amounts of organic matter)
- Elly will send labels of major brands of soap and detergent
- Individualized vs. Centralized Community System
- Individualized: more costly and higher maintenance, which may cause people to not use them
- Idea of underground system along the road that has two main filter points (can be seen on the design) with some kind of filtering device
- Ultimate goal: to keep water off the streets and to make sure graywater is not contaminating river water
- One filter point is right by a football field (plenty of area for a wetland system) but issue of digging up areas of the field
- Filter point on the left of design is not populated, but not much land
- Filter point in the center is very close to the homes and the river, so minimal amount of space
- Water source would be pumped from the right hand side
- Community on top right side has minimal access to water & more on the mountains, so would have to hold off development of graywater system until later
- In current water system, piping crosses at a high point in the community
- High school is located by pipes labeled “10 meters” and “11 meters”
- Graywater is placed in a dugout from the school
- Planning on water to be pumped to a tank near the school (highest point), and then use gravity for water to flow to the rest of the homes
- General goal of beginning with central houses on the river side, because no concern of graywater pipes intersecting with future water distribution pipes
Meeting Minutes 1/18/15
- DEID Exec
- Began meeting with more information on other DEID projects
- Obtained funding for Defy Gravity! Around 39 spots available, so look out for an email later to sign up first come, first serve
- Discussion with Dr. Schaad updates
- Reassured that area we will be traveling to will be safe
- Living situation: most likely living in the community and will go into the city for food and water
- May consider home-stay in the beginning (~1 week)
- Will ask Elly about availability of staying at a community center
- Will try to set-up a phone call with EWB and/or Elly
- Add any questions for EWB and/or Elly to the Drive
- Probably will be doing most of the design on our own with the help of Dr. Schaad and another professor
- Design
- Went over literature review for greywater system
- Considering tackling greywater system first, and then the water distribution system
- Trip this year can be viewed as an implementation trip for greywater, and an assessment for water distribution project
- Fundraising
- Dodgeball
- Tentative date: February 21st
- More discussion on assigning roles next week
Meeting Minutes 1/11/15
- Research
- Literature review on Google Drive under Design folder: try to find links relevant to greywater system or water distribution system and write a few sentences as a summary
- Greywater system: probably easiest to design self-contained systems in each house, but not much available space so systems would have to be compact
- Overall goal for design this year is to get everyone up to speed on design logistics/calculations, so everyone can contribute
- Information from EWB research on Drive: 4 plans
- Water to El Pital and not La Lucinda
- PVC pipes
- 3 beak pressure boxes to slow the speed of water
- No pumps
- 1 large tank above school (highest point in community) in El Pital
- Water to both El Pital and La Lucinda
- PVC pipes
- 1 pump
- 2 tanks (one above school, and one at La Lucinda)
- Water to El Pital and La Lucinda
- 2 tanks (one above school and one at La Lucinda)
- No pumps (just use gravity of water coming from source)
- Galvanized iron pipes (can withstand higher pressure so longer longevity but more difficult to install)
- Water to El Pital and some of La Lucinda (evaluated as best in document)
- 1 tank above school
- PVC pipes
- No pumps
- Break pressure boxes on the way down
- May be modified to have a holding tank in LL and use an electric pump that can provide water for houses that are not serviced
- Water to El Pital and not La Lucinda
- Ram Pump
- Water source would be much more elevated than El Pital, slightly more elevated than La Lucinda
- Might need a pump because break pressure boxes will cause water to not have enough energy to flow back to La Lucinda
- Matt and DEID exec are compiling a document that compiles various sources on the safety of traveling to and working in Honduras
- EWB team had positive experience with home stay
- Group would be spit up into different homes but in close vicinity

- Check out google drive for the email correspondence with Elly Goetz, director of El Mundo
- Recap of projects: need to figure out which 1 out of 3 projects to prioritize on for this year
- 1st year: composting toilets, greywater system, trash collection infrastructure(2nd year: river crossing device; 3rd/4th year: water redistribution)
- All staff members are Honduran, so basic proficiency in Spanish would be very useful in communication (one helpful app is DuoLingo)
- Most likely will have an assessment trip, but uncertain if enough time to prepare for an implementation trip
- Will pick travel teams early next semester
- Keep hometown fundraising opportunities and grants in mind
- Since designing the houses for Brazil and designing for the project(s) in Honduras is a lot to take on, Dr. Schaad will propose the projects to his class next semester to help in design
- Finals Week Study Break: Sunday during the reading period
- Planning to apply for Flex Webpage next semester

- Honduras:
- Phone call with Ellie Goetz from “Un Mundo”
- Community very involved in projects (tends to be slower process, but all board members are locals from Honduras)
- Project would occur at site which is collection of 28 communities, an hour outside of the city
- We would be working in the community with highest need
- EWB couldn’t implement design because of liability, but we can use EWB’s topographical data
