Sustainability• Extra materials supplied for maintenance and replacement.

• Locals will be educated on water conservation and proper system maintenance.

• Water Board willcollect usage tax to fund future repairs.

• Simple design and construction


Community Involvement


• How has the community been involved in this project?– During the site assessment we inquired about the community’s wishes and took

their input into consideration during the design process. Letters have been sent to the villagers for approval of the design.

• Was a second, follow-up assessment conducted once the initial designs were completed?

– No, there was no follow-up assessment, but this trip will serve as a follow-up assessment before designing the second phase of the implementation of the system.

• How did everyone agree on this design?– We discussed the tentative initial plan with the villagers and formed our design

based upon these original discussions.

• How many people will this project impact?– This project will impact the quality of life for approximately 350 people.

• Has the NGO been helpful?– ACTS, the NGO in the area, has been extremely helpful in the progression of this

project. Since they already have a traveling infrastructure set up in the area, it has been much easier than expected to secure safe places to stay, guides to the area, and reliable sources of information. In addition, the wealth of knowledge that the group has about the history of El Rosario and the surrounding area has been beneficial in understanding the culture and social dynamics of El Chaguite.

Community Ownership & Education


• What kind of help will the community be providing?– Labor (digging trench, laying pipe, mixing cement, transporting

materials).– We will coordinate a schedule of construction with El Chaguite’s

Water Board.

• Who will own the project once it’s completed? – El Chaguite will own the water system upon completion of the

project. The El Chaguite Water Board will manage the communally used infrastructure.

Community Ownership & Education


• Who will be overseeing maintenance once the team leaves and how will repairs be paid for?– El Chaguite’s Water Board will be overseeing the maintenance

of the system. We will leave extra materials with the villagers to take care of any immediate necessary repairs. Hopefully, with improved health, the villagers will be able to establish community funds and pay for repairs further in the future.

• What education will be provided to the community?– The community will be educated on the maintenance of the

system, and we also plan to provide information about health and sanitation. In order for this to be a successful effort we will be working with the community Water Board and local organizations to ensure that the people understand the situation and are well informed about health and sanitation issues.

information which may be useful.

Project Background


• The need for EWB-NEU’s previous project, Los Planes water supply project was realized by EWB-NEU and ACTS, a non-profit organization that has been working in the area for over 15 years.

• ACTS has been working on improving the quality of life in the area by implementing medicinal and educational programs in the village of El Rosario as well as several of the surrounding villages.

• EWB-NEU has completed two projects in the area working with the villages of El Tecuan and Los Planes. During this time EWB-NEU realized the need for a similar project in El Chaguite.

• EWB-NEU was approved for an assessment trip that occurred in December 2007. During the assessment all the data that was necessary to design the system was collected

• Due to the shear size of the village, amount of work and materials needed, the design will need to be implemented over at least two phases.

• The following presentation outlines the final design for the El Chaguite water project, design alternatives, logistics of travel, and budget for Phase One.

Accommodations


Dates, transportation, and lodging• Fly out of Boston on June 11, 2009. Pick up rental truck at the airport in San Pedro Sula and drive to the Hotel

Ejecutivo in the city.• Leave San Pedro Sula the next day, after securing materials, food and water. Travel 3.5 hours to the village of El

Rosario (location of the bunk house and ACTS clinic)• From June 11 to June 26 – travel between El Rosario, and surrounding villages, focusing our implementation

efforts on El Chaguite. Also travel to El Tecuan, La Reinada and Los Planes to check status of past projects.• Travel back to San Pedro Sula on December 28 and spend another night in the Hotel Ejecutivo in San Pedro

Sula. • Return Rental trucks and fly out of San Pedro Sula on December 29

Contact Information of accommodations• For the first and last nights the team we will be staying at the Hotel Ejecutivo in San Pedro Sula ( 011-504-552-

4289)• During the rest of the trip the team will be staying in a bunk house in El Rosario which is next to the health clinic.

There will be no way of directly contacting the team by phone during this phase of the project, however two households in this village have phones. (Santiago 011-504-608-6942, and Rosa Castro 011-504-608-7219)

Sources of food and water for the team• The first morning in San Pedro Sula, the team will shop for groceries. The team will also purchase all bottled

water needed for the trip. When in the villages the team will buy more, locally grown, food from the villagers, such as corn and beans. Food will be prepared by cooks in the bunk house.

State whether the team be visiting surrounding areas.• The majority of time will be spent in El Chaguite implementing the first phase of the project. For a few days

during the trip, the team will visit villages that EWB-NEU has worked with in the past, including El Tecuan, Los Planes and La Reinada.

Safety & Emergency Plan


Safety PlanEl Rosario and the surrounding villages are rural and the crime rate is very low. When crimes do happen it is very rare that they involve foreigners. The team will always be traveling in groups and two individuals from the village will be accompanying and guiding the group. There is a medical clinic in El Rosario with a well stocked pharmacy that ACTS has worked with for years. The bunk house will serve as a meeting place and the trucks will be available for emergency transportation.

Emergency Plan & Exit StrategySOS evacuation insurance was strongly suggested by the ACTS group in case of emergency. Political unrest is rare in Honduras. The country is considered one of the most politically stable countries in Central America. In case of emergency the team will exercise good judgment and use advice from the local guides to leave the country in the best way possible.

Are there any State Department Warnings for this country?As of March 19, 2009 there are no State Department Warnings for this country (information retrieved from US Department of State website)

Are there any other safety concerns for traveling at this time? Heavy rain and hurricanes have hit this area in the past. In case of extreme weather the team will stay off the roads and use best judgment with counsel from the locals

Implementation Metrics


Technical:

• Give a detailed description of the future monitoring of the impacts of your project

– Once the project is completed, the continuation of the monitoring of the system will be carried out by the community water board.

– We will initiate an education campaign to provide necessary water safety and sanitation information.

– Our chapter will remain in contact with the community to ensure that things are going smoothly, to provide any support that becomes necessary, and to ensure that the water availability issue has been fully addressed.

• What are the future plans for visiting and following up with any problems that might arise?

– We plan to implement this project in two phases, so the implementation trip for the second phase will also serve as a follow-up to the first phase.

– Since EWB-NEU plans on remaining active in the area around El Chaguite in the future, the group will check up on the village on any trips to the area. In addition, ACTS has a constant presence in El Rosario and the surrounding villages and can act as a liaison between El Chaguite and EWB-NEU.

Implementation Metrics(Health)


Health:

• Give a detailed description of the baseline health assessment

– In January 2008 a standard EWB 509 Health Assessment Form was completed for the community of El Chaguite by one of the village elders on behalf of EWB-NEU. It is the intent of EWB-NEU to distribute additional forms for completion by other villagers during the implementation trip. The additional responses will allow for a cross-section of the community and provide greater insight into the village health situation.

– Our team conducted a health assessment of the village of El Chaguite. Interviews were made house by house to determine the public health status of the residents. All comments were recorded along with the number of people in each household, gender, and age

Implementation Metrics(Health)


Health (continued)

• What health metrics were identified to measure the effect of this project on the community?

– We, or ACTS, will conduct another health survey after implementation to see if the number of cases of illnesses decreases after we improve the water availability in the village. We will be conducting water usage education and hope to improve basic sanitation practices in the village, such as encouraging hand washing. Through communication with ACTS in the future we can ask if spread of illnesses has decreased.

• What are the current health data findings? – The most common illnesses are malnutrition, headaches, common cold, diarrhea and fever.– Most of the illnesses listed are caused and/or spread more easily by the lack of clean and

reliable water in the village.

• What additional data is needed? – We may conduct more in depth water quality tests during the implementation trip to see if

water quality should be the focus of a future project in El Chaguite

Assessment for Future Project Phases


• Will this trip be used as a site assessment for future projects? – This trip will be used as an assessment for the second phase of this project.

Because of the scale of the project, we have decided to implement it in two phases. The second phase will focus on the reservoir tank, completion of the distribution system and setting up taps at all of the houses.

• What are the community’s main concerns?– The main concern is to obtain a reliable source of water. We hope to increase

serviceability with a new transmission main. After the first trip, the main concern will be getting water to each house.

• Site Assessment Data Needs: – Verify location for reservoir tank.

• This information will be obtained by collecting GPS and survey data of potential locations and doing soil stability analysis.

– Determine locations for all of the taps to be installed. • This information will be obtained by collecting GPS data of the village and

working with the families to determine where the taps will go.

Assessment for Future Project Phases: Methodology


• Describe the potential impacts to the physical environment that the project may cause.

– This project will affect the plant and animal life in the direct surroundings of the source box, float valve tank, reservoir tank, and water tap. We will attempt to make this effect as positive as possible.

• Describe what training your team has undergone/will undergo for this project.

– The team has knowledge in surveying and water systems, and will use the information gathered for the first phase of the design to help prepare for the project. In addition, the group has been educated by ACTS in regards to the cultural issues that exist in the area.


Assessment for Future Project Phases: Metrics

Technical:• What metrics will be used to determine the technical success of this project?

– This project will be successful if the village has full access to clean drinking water. The success will be measured as follows. Water pressures were measured at many places in the existing system. The proposed design strives for a minimum pressure of 20 pounds per square inch (psi) and a maximum pressure of 80 psi. Tap pressures within this range will be considered successful.

– The quality of the water is also important to the success of the system. Water tests were conducted by the EWB-NEU travel team in December 2008. For a successful implementation, all the taps in the community should test negative for contaminants. Each of these tests will be conducted at representative locations throughout the distribution network.

Economic:• What additional metrics will be used to measure the effect of the next phase of this

project on the community?– This project will significantly increase the health and quality of life for the people of El

Chaguite, primarily the families who were not served by the original system.– The villagers will have the opportunity to invest their energy into different things which can

only bring about a bright future forr thecommunity. – Moreover, the health problems in El Chaguite will reduce. Having a plentiful supply of clean

water for drinking, cooking and bathing will undoubtedly improve the health of these people.


Assessment for Future Project Phases: Metrics

Health:• What additional metrics will be used to measure the effect of the next phase of this

project on the community? – A health assessment has already been performed for the village of El Chaguite so we will

not need to collect another one at this time. After the project has been implemented, we may conduct a follow-up health survey to determine the effects of our system.

• What data is needed and from where will your team collect the data?– We have already gathered the necessary health information for this project.
