Post Implementation Report Part 2 – Technical Information

Revised 09/2014

1.0 Executive Summary

As part of an ongoing effort to improve water supply, storage, and distribution in Las Delicias, El

Salvador, a team of seven Philadelphia Professional Chapter members traveled to the village.

The primary goals of the trip were to:

(1) Install a cooling system on a variable frequency drive (VFD) controller for the 60-horsepower booster pump supplying water for most of the village

(2) Conduct water quality tests and chlorine tests

(3) Conduct a comprehensive health assessment

(4) Inspect the newly constructed tank and valve boxes

(5) Test the pumping system and determine the power consumption with the VFD in operation

(6) Meet with the local town council and discuss our progress

(7) Train the pump and valve operators on how to use the newly updated system

(8) Document the valve sequencing procedure for the distribution system

Goals (1), (2), (3), (4), (6), (7), were completed in whole. Goal (5) was mostly completed, except providing a final version of the operating manual in Spanish. Goal (8) was modified based on our findings at the site and time constraints (see below).

2.0 Program Background





Water Project

Revised 09/2014

The project is a retrofit of the existing water system (see the diagram above). The existing water production infrastructure includes a 275 foot deep production well, a submersible 15-HP pump, a 2000 gallon cistern adjacent to the wellhead, a 60-HP booster pump, a six inch diameter supply line servicing the previously existing “upper” Tanks 1 and 3 which are about 600 feet above the wellhead, and the newly constructed 18,000 gallon tank and adjacent previously existing 9,000 gallon tank, each of which are about 300 feet above the wellhead.

The system supplies water to a village of about 3000 people. For details see the subsequent sections.

Water Project

Revised 09/2014

Members stayed at the Project FIAT (NGO) guesthouse in San Salvador under the care of the

Handmaids of the Sacred Heart. Project FIAT provided shuttles to the project site in Las Delicias.

Pumping system

Barry, Brian, and Adam worked on installing the cooling system on a variable frequency drive (VFD) controller for the 60-horsepower booster pump. The team installed a cooler heat exchanger (water/fan type) in a “blister” on the cabinet containing the VFD (it involved cutting the original panel), did the trenching for water piping from the pump’s discharge to the exchanger and back to the pump’s sump cistern, installed the piping with the insulation on the cold piping only (it involved necessary penetration on the walls of the cistern and the control room).

After the task was completed the system was tested with the VFD in operation and power consumption determined while pumping to Tank 4 (at low elevation) and Tank 3 (at high elevation). The lower level shutdown on the water cistern was tested and adjusted. Power consumption results indicate we can save about 26% power, as anticipated (25-30%):

Water quality

Kat and Rob performed water quality tests (including coliforms) at several locations, including the well, the cistern, storage tanks, and the school. They also performed a chlorine test.

The E Coli tests were conducted to assess the level of contamination and identify the point of entry of fecal contamination in the community’s water supply. Chlorine demand tests were conducted to estimate the amount of chlorine that would need to be added to various points in the water supply in order to ensure adequate disinfection. When chlorine is added to water for disinfection, it will first react with organic matter, certain meta ls, and other compounds. This ‘demand’ reduces the effective disinfection capacity of the chlorine.

The E Coli tests were conducted at three of the community water tanks (Pump Cistern, New Tank and

Blue Tank), and the school water tank (post filtration). In addition, water stored at multiple homes served by each of the community tanks was tested. This water had been stored at the homes for varying times ranging from fresh (tank being filled when water was sampled) to 6-7 days old. E Coli levels in the community tanks and the school was 0 (i.e. not contaminated). However, each home that was sampled





Water Project

Revised 09/2014 was found to be highly contaminated with E Coli (average sample results ranged from 47 CFU/mL to >

100 CFU/mL).

The chlorine demand tests were conducted at three of the community water tanks (Pump Cistern, New

Tank and Blue Tank), the white school water tank (post filtration) and one home which was served by the

New Tank. The water at the home had been stored for 4-7 days. Chlorine demand was found to range from 0.7 mg/L to > 2 mg/L. The demand generally decreased as the water flowed from the pump to the

New Tank but increased with age at the homes. This suggests that the demand causing compounds are settling or reacting in the community tanks but the water then gets re-contaminated as it travels and/or as it sits in the open storage containers used at the homes.

Health Assessment

Ana and James conducted a water availability and public health assessment of the community by presenting a 35-questioned survey to 23 families/households (approximately 105 members).

Adults 66

Children

Total:

105

Males 42

Females 63

The health assessment questionnaire was implemented to assess water availability, individual household usage/storage of water and the associated health outcomes from those practices. The results of the survey determined the majority of the population receives water frequently. 52.2% receive their water once a week, 34.8% receive water every two weeks and only 4.3% of the community receive water every

3 weeks.

It was discovered that 43.5% of the families surveyed fully depend on the water distribution system for all daily uses such as (drinking, cooking, washing dishes, showering, etc). Of that group 78% of households treat their water via chlorine packets and other methods such as filters, abates (insecticide) and chimbolos (fish). Only 30.4% reported experiencing health sickness, such as diarrhea at least once a month.

Due to the on-going sickness occurred from drinking the water received by the distribution system, 78.3% of the members surveyed reported additionally purchasing bottled or packaged drinking water. On average drinking water is purchased in 5 gallon bottles at a cost of $2.40 per bottle. This translates to

$0.48/gal (last yea r’s number was $0.75/gal), Home use 1 bottle per day. Drinking water can also be purchased in large $1.25 packages consisting of 30, 0.5oz bags of water.





Water Project

Revised 09/2014

About 47.8% of households collect rainwater. Rainwater is mostly used for household chores and laundry.

A combination of Heath Assessment and water quality tests may suggest we should consider point-of-use purification. We are currently performing an alternative analysis of various options.

Flow tests

Ana, James, Kat, and Adam performed flow tests to determine water availability at different nodes of the distribution system. All nodes tested received water in abundance (0.4-0.7 GPM from the tap):

4.0 Project Summary

4.1 Project Description

Project is a retrofit of the existing water supply and distribution system consisting of two water pumps

(submersible and booster) and three tanks at high elevation. We added another tank at an intermediate elevation. Now we can pump about 25-30% more water for the same electricity price. The community was struggling with its water bill.

4.2 Summary

During this trip we installed a water-fin heat exchanger (HX) cooling the previously installed variable frequency drive (VFD) controller on the booster pump. The addition consists of (a) the HX, (b) the “blister” on the cabinet to contain the HX, (c) water piping from the booster pump discharge to the HX, (d) water piping from t he HX to the cistern at the booster pump’s sump. Other tasks included the ones described in

Trip Description.

Revised 09/2014

4.3 Difference Between Planned and Actual Implementation

All physical components were installed and tested exactly as planned. We were also to document the distribution valve sequencing. We could not do it due to time constraints (there was a power outage that delayed the VFD/cooling system commissioning) but it became a lower priority as the Water Committee is to train a second valve operator.

4.4 Drawings

Here is the system’s schematic (not to scale):

Water Project

Revised 09/2014

4.5 Operation and Maintenance

We explained the purpose and operation of the new cooling system to the Water Committee’s president

(Santiago) and the pump operator (Vincente). The O&M is minimal; it is a push-button system that turns with the pump. An important written instruction we provided was how to rewire the system form the VFD to no VFD operation (see the Appendix). It is a fallback position in case there is an issue with the VFD and/or the cooling system.

4.6 Sustainability

The piping leading to/from the HX was purchased locally and can be easily replaced, if needed. The VFD and the cooling HX are expensive components that are harder to replace. However, the energy savings are primarily due to the new water storage tank constructed at the intermediate elevation, built using local labor, materials, and expertise (local foreman). VFD and its cooling system provide a soft start, some additional savings, and a contingency in case the submersible pump flow is too low to match the booster pump. As mentioned previously, the system can be rewired to operate without the VFD.

Level of cleanliness of water storage tanks

Observed evidence of routine maintenance on the system done accurately without EWB-

USA village, and time required to distribute water. Typical pumping time is 3-4 hours about 4 times a week, with water distributed over two days.

In order to lengthen uptime, a detailed manual for the improved pumping system is being prepared The pump operator (Vincente) and the valve operator (Chilo) know how to run the new system.

Water tanks are free of harmful bacteria.

Not yet able to accurately report. However, maintenance was done on old motor and system is back up. The blockage to Tank 1 was fixed; tank is back in operation. The overflow tank next to the new tank was cleaned last spring.

The water committee received tank cleaning instruction from

EWB in May.

Observed method of community members storage of water

The heaths assessment indicates that community mostly stores water at individual households in various vessels (see photo under Photo

Documentation).

Cost of water to user Drinking water is purchased by about 50% of community in 5 gallon bottles at a cost of $2.40 per bottle. This translates to

$0.48/gal. The rest of the community uses water from the well. The monthly electric bill is about $1,200-1,400, for a community of about 3000. This translates to the water cost of about $0.001/gal (compared to

0.0015 in the US). Water from the well is also used for washing, bathing, etc.

8.5 Additional Information

9.0 Next Phase of the Program

In the longer term, the village has a definite need and interest water filtration and purification.

Our partnering NGO, Project FIAT, has offered $10,000 in assistance towards such a project and would again facilitate community involvement and logistics to gather data and later implement our solution. We are considering point-of-use purification and currently performing alternative analysis of various methods.





Water Project

Revised 09/2014

Project FIAT also promoted the need for improved water distribution to some currently underserved areas of the village and a specific group of 9 houses adjacent to the village that are not served at all by distribution. Additional needs and wants include replacing aging water distribution infrastructure, implementing a cleaning regimen for the tanks, adding redundant sensors to help prevent ever running a tank or well dry, replacing the check valve on the booster pump, re-building the valve boxes, and implementing a locking system to help prevent vandalism.

Our next steps as a chapter will be to discuss with Project FIAT, ADESCO on behalf of the community of Las Delicias, and our own members, which tasks to address, and to develop an action plan for each selected task.

We are planning another trip in late 2015 or early 2016 to focus on point-of-use water purification and education (water storage, hygiene,. etc.)
