Post Implementation Report Part 2 – Technical Information

1.0 EXECUTIVE SUMMARY

The Philadelphia Professional Chapter performed a second implementation trip from May 20th – 27th, 2014 for the Water Distribution Project, Las Delicias, El Salvador. The scope of this second implementation trip was to continue the program of providing reliable, potable water for the Las Delicias community by testing and assessing the success of the water distribution system extension and new storage tank flow rates. This extension and new storage tank were previously implemented on the first trip taking place from January 11th – 18th, 2014. The specific goal was to ensure that clean, potable water was being distributed throughout the village. In addition, the Temple travel team began progress for a potential Senior Design project that will answer the problems of the local school, being stormwater management, soil erosion and retaining wall failure. The goal of the Temple team was to obtain enough topographical data of the school in order to develop a base plan to be used as a reference in the future of the project.

The community of Las Delicias is and consists of approximately 3000 residents. The program was initiated in response to the previous assessment trip, providing a follow up to the valve box implementation and addressing issues raised about the infrastructure of the school.

In the end, our group successfully confirmed that the new storage tank was not properly sealed, the new storage tank and distribution system can provide water to the entire village and that there is no measurable chlorine in the tap water. We also submitted water samples to a lab, where the results confirmed that the school water was not contaminated by coliform bacteria, salmonella or legionella. A topographical survey was also completed as well as a base plan to be used for future reference for the Senior Design project.

2.0 INTRODUCTION

3.0 PROGRAM BACKGROUND

The water supply system of Las Delicias was installed around 20 years ago. The system consists of buried piping to individual households, three storage tanks at upper elevations in the community, two storage tanks at the midsection of the community, over 150 valves to control distribution, a well at a lower elevation in the community and a pumping station with two pumps, one submersible, the other to transfer water to two of the tanks. Some residents leave the faucets in their homes open constantly so that they do not miss an opportunity to collect water. The community has a water committee, ADESCO, to promote a healthier society within the community.

4.0 TRIP DESCRIPTION

The trip occurred from Tuesday May 20 through Tue May 27. Travelers included Jonathan Campos (EWB-Phila Prof Chapter), Dr Robert Ryan (EWB-Temple Student Chapter, Advisor), Kenneth Paszek (EWB-Temple Student Chapter), Torin Johnson (EWB-Temple Student Chapter) and Paulina Olmedo (EWB-Temple Student Chapter). The main purpose of the trip was to (1) check the status of the newly



installed water storage tank and water distribution system extension; (2) test the water flow rates achievable from the new water storage tank; and (3) meet with the School Director to discuss water quality and other issues at the school (stormwater management, soil erosion, retaining wall failure, etc). These issues were raised by the School Director in our previous trip in January 2014..

Upon arrival in San Salvador, the team was picked up at the airport by a driver hired by Handmaids of the Sacred Heart, the local NGO we have been working with. We settled into our accommodations and later met to discuss and review our plan for the week. The Temple students set up and practiced using the surveying equipment.

On Wednesday May 21, we traveled to Las Delicias and we met with the Treasurer (Cecilia) and Secretary (Sergio) of ADESCO, the water committee and agreed to meet with the full ADESCO board on Wednesday. After our meeting, we walked through the community with Sergio to locate the valve boxes we will need to access in order to test the distribution system. In addition, the team inspected the new storage tank and confirmed the presence of cracks and evidence of seepage through the tank wall. The organization that had designed and constructed the tank indicated that it was sealed. However, the presence of cracks and seepage suggest this was either not done or not done properly. ADI, the company that makes the sealant, was contacted and agreed to develop a cost estimate, including materials, labor and warranty, to properly seal the water tank.

On Thursday May 22, the Temple team went to the school to meet with the Director and discuss the issues or problems he deems most important. The discussion was very fruitful and based on this, the team is interested in formally pursuing a project at the school to address the issues with stormwater management, soil erosion and retaining wall failure. The three issues are all directly related to the deteriorated condition of the existing stormwater collection channels within the school yard and a lack of proper stormwater management around the school property. The Temple team began a topographic survey of the property using a Topcon Total Station, lent to the team by Temple University Department of Civil and Environmental Engineering.

Other members of the travel team met with the full ADESCO board as well as with Chilo (responsible for operating the water distribution system) and Miguel (employee and liaison of local NGO). We discussed our plans for the trip in the morning, including testing the water distribution system, new storage tank and flow rates achievable at various homes. In the afternoon we worked with Chilo to test the water distribution system. The new tank was filled and water was distributed to the southern leg of the system (Tramo 6 in Figure 1). All homes visited were receiving water at a rate of 1.7 L/min to 27 L/min (a greater than 10 fold difference). The difference can be attributed to several factors including total head in the storage tank at the time of testing; elevation at test point (homes at higher elevations will have lower flow rates); friction loss in distribution system (homes further from storage tank or being served by smaller diameter pipes will have lower flow rates) The lowest flow was observed at a home near the end of the tested distribution system and the ground elevation at the tap was approximately 10 ft higher than the elevation at the main road (See Fig 2). The most distant homes were not tested (these homes were later tested on Monday). In addition, we learned that the distribution system is slightly modified from our original understanding. As shown in Fig 3 below, several homes that we believed were connected to the northern leg of the system are in fact connected to the southern leg.

On Friday May 23, while the Temple team continued surveying the school property, other travel team members met again with Chilo and Miguel to discuss the next phase of water distribution testing. Water is normally distributed to different parts of the community on Mondays, Tuesdays and Wednesdays. The northern portion of the community normally gets water from another storage tank on Mondays. It was agreed that on Monday, Chilo would fill the new tank and use that to deliver water instead of the older storage tank and we would then be able to test the flow rates from the new tank.

We then met with the community health professional (Morena) and Chilo after our discussion with Miguel and Chillo. Morena told us there are 700 viviendas (homes) in Las Delicias with a total population of 2556 persons. Morena sees about 20 cases permonth of water-related bacterial and parasite infections. She said out of 22 recent and current pregnant women, 18 have urinary tract infection, 3 had premature births, and 1 miscarriage. She believes some of these infections may be related to impure water. The government provides anti-parasitic medicine, influenza vaccine (Vaxgrip), and pneumococcal polysaccharide conjugate vaccine.

Morena uses a colorimetric chlorine test kit, ortotolidino, on a regular basis but says she does not find any presence of chlorine in the water. She tested the water from the sink in her office and there was no indication of any chlorine. Chilo claims he adds two tablets (each 3 inch diameter, ~300 g and 70% active chlorine) to Tanks 1 and 3 each time the tanks are filled (Tank 2 is spring fed and thought to be a non-issue).. We then went to the home where he keeps the chlorine. The chlorine he showed us was, manufactured in 2008. They receive the chlorine in 2009 and the container is still 1/4th full. Based on this, it is doubtful that the chlorine is being added as indicated. However, if the chlorine is being added as claimed, the lack of measurable chlorine at the tap may be due to a mixing problem, a high chlorine demand in the water or old chlorine which has lost its disinfection capacity. In any case, additional training will need to be provided on the use, storage and disposal of chlorine tablets.

At the end of the day, we picked up sample bottles from the local analytical lab (LECC) to be used to collect samples to be tested for bacteria, salmonella and legionella. The samples were collected on Monday from the School water tanks and submitted to the lab.


Tramo 6


On Saturday May 24, the Temple team conducted a shortened day of surveying because the school was only open until noon. The remainder of the travel team met again with Chilo and Miguel. We discussed the issue of sediment in the storage tanks. The older storage tank which served the community day care does not have a proper cleanout and so it was not be flushed on a regular basis. Sediment built up over the course of approximately one year to a depth of about 20 cm. This sediment caused taste and color issues (and potentially pathogenic concerns) at the day care. The older tank was cleaned out and the sediment problem appears to have been resolved. The community will need to continue cleaning this tank by hand on a regular basis until a proper cleanout port can be added.

On Sundays very little work can be accomplished in the community so we used the day to visit some cultural and tourist sites. .

On Monday May 26, the Temple team completed the topographic survey of the school property. More than 200 survey points were shot and a photograph was taken for each shot and for each survey station. In addition, samples were collected from two of the three water tanks on the school property (one of the tanks was empty). The water samples were immediately put on ice and delivered to the analytical lab (LECC) in San Salvador for analysis (note, the lab results have now been received and the water is not contaminated with coliform bacteria, salmonella or legionella). The rest of the travel team completed the testing of the water distribution system. The new storage tank was filled and water was then distributed to the northern leg of the system to be served by this tank (see Fig 4). All homes that were tested received water with flow rates ranging from 2.1 L/min to 22.7 L/min. One home reported that they do not receive water at all, but we could not verify this because they would not allow us onto their property. Here, again, the 10 fold variation in water flow may be due to several issues such as actual head in the storage tank at time of testing, distance from storage tank, pipe diameter serving home, and elevation difference between water tap and storage tank.

In addition to testing water flow, we interviewed seven households about their use of cooking fuel because Morena indicated that the community members often have health concerns with breathing. All 7 households use both gas and wood: wood to cook food that takes more time such as beans and tortilla; gas for making coffee or boiling eggs. Most households had gas inside of the house and wood fireplace outside in a semi-open enclosure. A bundle of wood cost $20/bundle. The use of wood outdoors will help minimize exposure to wood smoke, but cooking in general generates significant amount of smoke and this may be any area of future investigation.

Tramo 6


Figure 4. The northern leg (Calle Principal) of the water distribution system and the far end of the southern leg (Tramo 6) are shown in blue. Both of these segments were tested on Monday May 26.

We talked with Dr. de Paz, who staffs the community clinic (he works independently of Morena, the community nurse) about his impressions and the health concerns he sees. He sees maybe 20-30 people a day (Morena sees many more). Dr. de Paz says that most parasite infections are amoeba. He thinks this is because many people go to the bathroom behind the house, without using the latrine, and the amoebas remain in the soil and then reinfect people, especially children who don't wash their hands. It is possible that the amoebas enter water containers via dirty hands. He says e. coli are not an issue. He is going to send us an updated heath assessment.

On Tuesday May 27, the team headed home.

In summary, the trip accomplished the following:1) Confirmed that the new storage tank had not been properly sealed2) Confirmed that the new storage tank and distribution system are capable of providing water to the entire design area3) Confirmed that the school water is not contaminated by coliform bacteria, salmonella, or legionella4) Completed a topographic survey of the school property that can be used in the future to address a multitude of issues, including stormwater runoff, soil erosion, and failure of retaining walls5) Confirmed that while chlorine is supposed to be added to the water supply tanks, there is no measurable chlorine in the water at the tap.

5.0 COMMUNITY INFORMATION

5.1 Description of Community



Las Delicias is a community of about 600 homes and 3000 people situated on the western slopes of Volcan San Salvador about 15 miles northwest of San Salvador, the capital of El Salvador. The community is fairly sparse and anticipates growth to over 1000 families over the next 20 years. The communities residents suffer from lack of employment, but over recent years several NGOs have begun making improvements within the community that are improving living conditions, health, and education.The residences of Las Delicias are Latin American and mostly agricultural. Some are Indigenous. The Village of Las Delicias was disrupted during the civil war, as were many villages, there is no real governmental involvement. There is some military and police presence. Most community event planning is done through the parish council. As stated previously, unemployment is very high. Those who are employed work in garment factories or agricultural labor. The average income is around $10 a week. Most people are Catholic.

Las Delicias has a water supply system that was installed about 20 years ago. This system includes buried piping to individual households, three storage tanks at upper elevations in the community, two storage tanks at the midsection of the community, over 150 valves to control distribution, a well at a lower elevation in the community and a pumping station with two pumps: (1) submersible pump in the well and (2) transfer pump for delivering water to two of the storage tanks. The three high storage tanks all receive water by gravity from a spring located several kilometers away, higher up on the mountain and two of the storage tanks receive water from the well. The two tanks can receive water from the higher tanks but will normally receive water from the well. The well pump and transfer pump operate about 4-6 hours per day, Monday Tuesday and Wednesday. Water flows by gravity from the tanks to individual households. The valves throughout the community are operated manually by a single operator who walks throughout the community controlling which zones have running water at various times during the day. However due to topology and limitations of the piping system design, the water supply to individual households varies considerably. Some homes receive water almost every day whereas other homes reportedly receive water less than once per week. A culture of scarcity exists in the community so that when the water is running, residents collect water into many available containers so that they will continue to have water until the next time the water is running. Some homes leave their faucets open constantly so that they do not miss an opportunity to collect water.

The community has a water committee, ADESCO, which meets to discuss the issues that arise due to the lack of clean water. The group has had their share of problems keeping peace and member attendance, as most groups do, but they have been helpful for the community to progress into a sustainable healthy society. They have met with the EWB group numerous times and are willing to help move forward helping Las Delicias.

The community is centered by a school that is mostly directed towards kindergarden through 9th grade. Approximatly 600 students attend this school during the week adults looking to become literate or learn specific subjects attending during weekends. The school is consumed with dangerous terrain and poorly kept facilities. The toilets in the bathrooms must be flushed with a bucket of water that the children stick their hands in each time they use the lavatory.

5.2 Community Relations

The Las Delicias community has been involved with the Las Delicias Water Project from the very beginning, even before implementation. Community members such as Miguel LastName and ADESCO PRESIDENT, who are members of the community water counsel. This counsel monitors the different aspects of the water system throughout the community. The EWB-Philadelphia Chapter has been in constant contact with these members to monitor the status of project, weekly. Other community members such has Chilo LastName have aided the project during the implementation trip. The community has completed a great deal of the manual labor while the EWB-Philadelphia Chapter was not present, in-country. Members work daily to complete the tasks that ADESCO and other community leaders set in coordination with EWB-Philadelphia.



During the several implementation trips community members have been present working in all conditions digging trenches, carrying supplies and discussing ideas. During the past two implementation trips there have not been any serious arguments between EWB-Philly and the community. There have been issues within the community regarding leadership and responsibilities but all issues have seemingly worked out over time.

The community treats the projects as it should be treated. It is their responsibility and we are there for added guidance and support for them. Between trips is the time most of the work is completed and during these times, many different groups from the community band together to complete tasks; men, women, and even the young are all involved.

6.0 PROJECT SUMMARY

6.1 Project Description

The community identified a need for improved water distribution. We found out that families were receiving water __ times per month. Thus, our goals are to distribute water to the entire community and minimize the pumping energy cost for distribution in the community through construction of a tank at an intermediate elevation that will serve __% of homes and installation of a Variable Frequency Drive (VFD) on the pump to optimize operation.

6.2 Summary

January 2013

The ground was prepared and the concrete was laid to build the new 16,500 gal tank.

Piping was laid for distribution from the new tank.

Valve boxes were built to control distribution from the new tank and filling the new tank.

May 2014

No implementation, testing and system analysis.

6.3 Difference Between Planned and Actual Implementation

We planned on using the Sika Flex concrete sealant to seal the tank noted in the 525 submitted April 2012, however we ran out of time during the trip. We asked an NGO representative to apply the sealant, but it was not applied and got lost.

Please check for accuracy and add other differences.


Operation: The valve opening and closing sequence in the valve box for filling and emptying the new tank was demonstrated. It was also shown that the new tank empties into the tank next to it when overfilled.

Maintenance: The valves and piping must be monitored for leaking and potential bursting—the community has experience doing maintenance on these components. We also became aware of how the community removes sediment from the tanks that builds up overtime. Once per month the tanks will be partially filled with a floor level outlet pipe open to flush out sediment on the tank floor.

Operation and maintenance costs are covered by ADESCO, which collects funds from the community.
