2 Community Need Background Hand pumped groundwater wells are the primary source of clean drinking water for the people in the villages surrounding Dissin.Women and children travel as far as two kilometers to retrieve water for daily drinking and hygiene.Long lines form at the pump, taking up to an hour to retrieve water.Because of poor food stability in the dry season, children in the communities oftentimes do not get the vitamins and minerals critical to proper development and good health.The community has suggested that automating the pumping process and storing the water in a tank would allow for easier water access from faucets, resulting in:Less time waiting in line.Women and children having more time to work or go to school.Increased water access and ability to irrigate subsistence crops to benefit community well-being.Potential for commercial water uses.
3 Two-Phase ProjectPhase I: Solar powered lighting for community education centersAssessment: January 2007Implementation: January 2008Project Status: CompletePhase II: Solar powered automation of existing ground water pumpsAssessment: July 2007Implementation: June 2008Project Status: Proposal to Implement
4 Phase II Objectives Primary objective: Secondary objective: To increase access to water in communities surrounding DissinSecondary objective:Enable the communities to develop irrigated family gardens surrounding the wells forImproved healthSource of trade and income within the community during the dry seasonImproved hygiene
5 Existing Infrastructure Several types of covered hand pumps; some common designsPumps range from 2-25 years of ageEach pump serves up to 600 people, with ~100 people using the pump dailyHistorically poor maintenanceHigh traffic in the mornings between 8 -11amWait time up to an hourUp to two kilometers walking distance to nearest pumpPoint source distributionHand Crank“Volunta” wheelFoot pump
6 Site Selection I Two sites were identified to be retrofitted: Mou Bormetewserves ~500 people2000m2 available garden space with only 80m2 currently usedNakarserves ~600 people3000m2 available garden space with only 80m2 currently usedAlternate site: Koin Dakoleserves ~240 people1000m2 available garden space with only 100m2 currently used
7 Site Selection II Selection criteria Each community made a commitment for maintenance.Established a project maintenance fund.Personnel are assigned to maintenance.Community members are willing to assist in project implementation.Gardening revenues will go to the families using the garden.Community members will continue to pay for their water use.Gardening already exists at the pump sites, and the community wants to expand their gardens, with the help of local NGOs.Long lines form during common pumping times.All pumps are “Volunta” Wheel style installed in 2004Easiest to retrofit, with some retrofit designs already implemented locally.Most reliable pump style, with least maintenance.Recent installations.
8 Potential Community Impacts Positive:Women and children have more time for school and work – productivity increases.Less energy required to retrieve water.Decreased incidence of famine.Increased household income during the dry season.NegativeChanging community dynamic as women may spend less time at the pumps socializing.Gardening in the dry season may distract from other community activities, such as rebuilding homes and community service.
9 Motor attached to “Volunta” pump (Motor Sub-system) Proposed SolutionThe proposed system consists of three sub-systems. The “Volunta” pump will be driven by an electric gearmotor, powered by three solar panels. Pumped water will be stored in a ferrocement tank, which will be accessible through 4 spigots at a collection site.Motor attached to “Volunta” pump (Motor Sub-system)Tank and Spigot design(Tank sub-system)Panels on top of Tank(Solar Sub-system)
10 Solar Sub-System Objectives: Provide power to a ½ hp DC electric geared motor.Use “current-boosting” technology to allow motor to run longer.Protect the panels from back-emf from the motor.Ensure physical security of solar modules.
11 Solar Panels Physical Characteristics of a BP3160 Solar Panel: Dimension:Length: 1593mmWidth: 790 mmDepth: 50mmWeight: 15.0kg (33.1 lbs)Mounting:Frame: Anodized aluminum alloy type 6063T6 Universal frameEasy attachment with screws/mounting tools
13 Solar Panels – Electrical Characteristics PMax = Maximum power point, the largest amount of power received by the panelsOccurs at a current draw of 4.55 Amps and voltage of 35.1VCurrent Draw vs. Voltage(At full sunlight)
14 Characterizing Captured Solar Energy Model Peak Sun-Hour data and Panel Rating:Peak Sun-hours/Day = 5.0 HoursBP3160Rated at 152 WattsPanels in system = 3Power available in peak sun = 456 WattsPower needed = Hp = 187 Watts (derived from 22ft-lb required torque at 60 rpm)Max draw from the motor = ½ Hp = 373 WattsLimitationsBased on ideal rating dataMay be overestimation
15 Solar Insolation Model Average Solar Insolation in Northern Africa Burkina Faso (Average solar insolation = 5.5 kWh/m2/day )
16 Solar Insolation Model Daily average solar insolation (kWh/m2/day) represented in Figure 1.1.Solar insolation throughout the day changes as a sine curve (approximation). Values are set for sunrise, sunset, and solar noon in Figure 1.2.These data are for January 1st, the day with the lowest solar insolation in Burkina Faso.More power will be received than is needed for three hours each day, at which point the motor will run at full speed.An adequate amount of power will drive the motor at reduced speed for approximately four hours each day.Limitations of this model:The calculations are an underestimation (worst expected conditions).Assumptions:Use 15% panel efficiency (data from BP solar).Panel Area = 1.23 m2Power needed = 187 WattsFigure 1.1Figure 1.2
17 System Losses Only significant in extreme cases Not significant Peak temperature Burkina Faso: 90° F = 32.2° CPower loss at -0.5% / °C (worst case) = -16.1%Would occur during peak time of the day when solar insolation is highest.Panels will be raised to allow air-flow beneath them (recommended by manufacturer).Power losses through wiringWire Gauge = 12 AWGTotal wiring span = 50 ft (maximum)Maximum power loss through system = 4.5 Watts1.8% of desired power (not a significant amount)Only significant in extreme casesNot significant
18 Solar Pump Controller The system will use a solar pump controller to: Provide the required current boost to overcome static forces required to start the motor.Provide enough current to the motor in the morning to begin operation in low-sunlight conditions (“Current-boosting technology” using a toroid transformer). This can extend pumping time by up to two hours daily.Regulate voltage at 90VSolar water pumping system is functional without controller.System designed with bypass switch in case of controller failure.
19 Solar Pump Controller Daily cycle: 7 am on worst day (from previous slide) :Motor needs 6 amps (approximation) to overcome static forces, 3 amps to continue movingSolar array can only provide 110 Watts at this time in dayPanels can only provide 5 amps maximum on their ownController transforms power generated by panels to provide higher current at the expense of voltageCurrent boost enables motor to overcome static resistance of systemP = 110 watts (Maximum power 7am)Current Needed = 6 amps (approximation of required amperage) P = IV 110 = 6*VV = 18.3 volts Voltage is pulled down to 18.3 volts to provide the current needed to start the motor. *Motor has now started moving, very slowly, now only requires 3 amps to continue turning* Power provided = P = 110 watts Current needed = I = 3 amps P=IV 110 = 3*V V = 36.6 volts *Motor is now running at 36.6 volts and 3 amps, at a faster speed*Without the pump controller the motor would not be able to overcome the static forces until much later in the dayCurrent boost not necessary in dynamic steady state
20 Solar Panel Mounting System Theft Proof Mounting SystemAccessible for serviceInaccessible to thievesMain IdeaBolt runs through 4 corners of solar panel through to the inside of tankNut inside of tank tightens panel down to tankDisassembly from inside of tank only (Alarm equipped padlock on the tank manhole)Accessory componentsAluminum pipe sections act as risers to hold panels above tankAir flow under panels increases efficiency (per manufacturer recommendations)PVC conduit runs through tankBolt runs through conduitAluminum riser pipe full of cement outside PVC conduitExtra support against sawingSteel angle channels enclose aluminum pipe and conduit assemblyExtremely difficult to sawHides securing assembly from view completely
21 Mounting Continued Special considerations Long bolt through panel and tank is a threaded rod.Could not place bolt in panel because of dimensions.Threaded rod with a nut on each end acts like a bolt.Special security nut connecting panel to tank breaks away to smooth head.After tightening, nut breaks away, turning into a bolt head.Outer panels actually have five feet, not four.Tank dimensions force rearranging outside corner leg supports to be on the tank.These legs are not critical in terms of security, though they provide additional reinforcement.

27 Motor Sub-System Objectives: The motor will provide adequate torque to spin the existing pump at ~60 rpm as long as there is adequate power from the solar array.The belt system will be simply designed and easily replaceable in country for low cost.The belt system sprag clutch (freewheel) will allow the community to pump with the flywheel without disconnecting the motor assembly.The motor system placement will be non-obtrusive.
29 Preliminary Design 1: Direct Drive (Front Mount) AdvantagesSimple mounting designDoes not obstruct pump outlet pipeDiscounted Because:Unreasonable precision necessary to keep motor shaft and pump shaft in alignmentSystem would have to be disassembled to pump manually (invites damage, proper reassembly is unlikely)Accidental damage could cause misalignment and jeopardize the entire system
30 Preliminary Design 2: Direct Drive (Rear Mount) AdvantagesDoes not engage flywheel (leaves room for manual pumping)Eliminates slippage concern present with beltsDiscounted Because:Unreasonable precision necessary to keep motor shaft and pump shaft in alignmentSupport structure would obstruct pump outlet pipeAccidental damage could cause misalignment and jeopardize the entire system
31 Preliminary Design 3: Drive Wheel – Pump Wheel Spur Assembly AdvantagesRelatively unobtrusiveEliminates alignment concerns present in direct drive systemsDiscounted Because:Irregular eccentricity of the flywheel means that the distance between the ground and the bottom of the wheel varies by ~3cm. This will cause any assembly attached to the wheel’s rim to oscillate considerably, placing undue stress on the system.Motor/Drive Wheel
32 Preliminary Design 3: Belt Drive (Along Rim of Wheel) AdvantagesDoes not obstruct pump wheel or outlet pipeSimilar methods have been used frequently and with successDiscounted Because:Large area assumed by the belt makes the system obtrusiveFlat belts will walk off the pump wheelSafety concerns (fingers can get sucked between the belt and the flywheel
33 Motor Assembly General Description Belt Drive ConceptTwo v-belt pulleys: One on the pump shaft, one on the motor shaftMotor is mounted on a sled that slides along a pair of parallel 80/20 rails; secured using set screwsSprag clutch (freewheel) connects motor to drive pulley
34 Power Requirement Calculations According to a performance sheet provided by Grainger, the gear ratio of the 6Z416 is 28:1. Therefore the motor output torque, motor RPM and gearbox RPM can be calculated as follows:At this performance level, the manufacturer’s charts indicate that the motor will draw 2.54 amps (or 230 watts).
35 Belt Slip Calculations To ensure that the belt will not slip when tensioned to 500 Newtons (250 Newtons on each half), the following calculations can be made.With the considered tension, the belt will be able to handle more than twice the torque load we require
36 Expected Performance Summary Based on the Grainger performance curve for the 6Z416 motor, the motor is expected to perform as follows:Torque (ft-lbs)22RPM65Power (Mech, HP)0.27Current (Amps)2.4Power (Elec, Watts)230
37 Design of the Motor Assembly Concerning: Community Interaction:Mounting is unobtrusive (blocks neither the flywheel nor the outlet pipe)Disassembly is not required to turn the pump manually (function of the sprag clutch)Belt is replaceable in countryBelt and pulleys can be enclosed to prevent injuryRequires little maintenanceSustainability:Motor will power pump at 60rpmThis is the approximate manual pump ratePlaces no extraneous stresses on the pumpUse of nonferrous metals will forestall rustParts are replaceable in country
38 System MaintenanceHistorically poor maintenance of bearings and pump components on existing system.The planned system will require minimal maintenance.Condition of the project is that community must train workers for scheduled, preventative maintenance, and reactive maintenance, such as replacing v-belt.
39 Motor Installation Installation Instructions: Please note that numbers in parenthesis refer to the labels on the figure to the right.Drill screw holes through the 80/20 (4) rails and corresponding holes in the mounting sheet so that the rails will be mounted parallel in a vertical fashion.Drill 4 bolt holes (3/8”) in the four corners of the mounting sheet.Drill 4 bolt holes in the concrete flywheel stand corresponding to those in the mounting sheet (5).Press the mounting sheet against the concrete stand so that the bottom edge is as close to parallel with the ground as possible.Using one of the holes in the mounting sheet as a stencil, drill the first hole into the concrete and secure the mounting sheet to the concrete with a bolt and anchor (so that the mounting sheet is now fixed to the stand at that point). At this point, the mounting sheet may be pivoted around the bolt to reassume a vertical position.Follow the same procedure as stated in step 2 for the next 3 holes, beginning with the hole diagonal to the first.Mount the 80/20 rails on the mounting sheet using screws and the holes drilled in step 1.Drill 4 holes in the motor sled (2) corresponding to those in the motor and 4 holes for mounting the L-brackets (3).Mount the motor and L-brackets onto the sled.Unbolt and remove the pump flywheel from the pump shaft.Slide one pulley (8) over the pump shaft and secure with a set screw.Attach the sprag clutch to the motor shaft and bolt the second pulley (6) to the clutch.Place bolts loosely in the L-brackets so that the bolt head is facing inward.Slide the motor sled into the rails, so that the bolt heads run through the channels in the 80/20.With the motor at the top of the rails, fit the belt (7) over the pulleys.Push the motor down to tension the belt and tighten nuts over the bolts so that the sled is secure.Reassemble the flywheel.

45 Tank Sizing Calculations Maximum observed flowrate on existing pump was 27 L/minAbout to pump for the full time equivalent (FTE) of 5.5 hours a dayTotal water pumped (TWP) is 9,167 LThis allows for water usage of 150 people and up to 600 m2 of garden areaPersonal water usage may increase, decreasing water available for gardening
47 Obtaining Minimum Flow rates Minimum flow rate is 12L/min (what they pump by hand already)A given geometry will dictate required head for minimum headDecision to use 1.5” NPT or metric equivalent to minimize losses9” of head is required to provide minimum flow rateA full tank (~2.25m) provides 38L/min to 4 spigotsWhere “Klosses” is the loss factors for all components in the line. “f” is the Darcy friction factor. “L” is the piping length. “d” is the pipe diameter. “V” is the water velocity. “g” is the acceleration of gravity.
48 Summary of Leach FieldThe Leach field (soak pit) is a trench filled with gravel and lined with newspaper.The purpose is to allow water to soak easily and relatively quickly into the ground back to the water table.Both the purge pipe and overflow pipe will lead to the Leach field.It will be located about 10 meters away from the system to prevent erosion.

54 Structural Integrity of the Tank Mechanical FailuresFoundation CrackingLoad testing for the foundation is being conducted through simulations and results show that it can support the predicted weight with a factor of safety of 10 (tank and water).Undermining of the Foundation by RunoffGravel bed below the tank will allow for water to flow away from the tank without accumulating underneath it or dragging large amounts of soil away in the process. Gravel surrounding the foundation (and even with the ground) will prevent erosion around the tank. A concrete lip on the outer edge of the foundation (extending to a deeper depth than the rest of the foundation) will further prevent water from flowing underneath the tank.Rebar CorrosionCorrosion of the rebar is primarily affected by the diameter of the rebar. Using a smaller-sized rebar (~6.0mm) will mitigate this problem and increasing the number of rebar rods in the walls will preserve their strength.Water Pressure Breaking WallsLoad testing for the walls is being conducted through simulations and results show that it can support several orders of magnitude more weight (water) than will be present.
55 Mechanical Failures Continued Pipes ClogIt is known that the water in the region is quite hard (high mineral content). The length of piping will be minimized and the diameter of the piping will be made as large as feasible to mitigate the chances of clogs and mineral deposit accumulation. The pipes will be designed to remain either wet or dry all the time, so as to minimize deposits. The tap-stand pipe will also be elevated above any silt-levels. The overflow pipe will contain mosquito-netting to prevent contamination.Cracking Around Water Pipes (swelling, people knocking the pipes & temperature changes)In all feasible situations, pipes will be buried or internalized to avoid mishandling (between the pump and tank, drainage from the tank, spigots for water use) and any pipes extending out of the tank (spigots) will be reinforced and made short enough to prevent damage to the tank should they be hit. Temperatures remain well above freezing for virtually the entire year so no additional insulation is necessary to prevent pipes from cracking or breaking.Roof Cave-inLoad testing for the roof is being conducted through simulations to locate areas of large stress/strain and to determine if it will be able to support its own weight. To reinforce the roof the presence of a central support column (PVC pipe filled with concrete) should be able to help distribute the weight of the tank between the walls and the center. Structual analysis is provided in following slidesPeople Cannot Access the Inside for MaintenanceA hatch will be integrated into the roof of the tank to allow for access when cleaning and repairs are necessary. The hatch will be secured with a lock to prevent children from accessing it. Diameter of the manhole is 2 feet

59 Community Ownership and Labor Describe the help that community will be providing.The community will coordinate movement of materials to the site prior to the team’s arrival.Five community members that will later use the system have been recruited to assist with labor. The community will pay them. Implementation of the Phase I project experienced overwhelming community participation and assistance, even when not formally requested.Explain who will own the project once it’s completed.The wells are viewed as communal property of the community, and the retrofit system will also belong to the community. Members using the water will continue to pay for its use, and this money will be administered by an existing committee to ensure proper maintenance of the system, as well as for other community projects.Explain who will be overseeing maintenance once the team leaves and how repairs will be paid for.The existing community committee that oversees usage fees and maintenance of the well will continue to take care of the system.What education will be provided to the community?The Five community members that have been recruited to help build the project will be trained how to do routine preventative maintenance. A manual (with pictures) will also be given to these community members to illustrate reactive maintenance, as necessary.This project aims to facilitate gardening at select pumping sites, such as to set an example for other pump sites at the region – spreading the practice of gardening in the dry season to prevent famine.

64 Safety & Emergency Plan - I Travel Safety Information:Safety PlanTeam members will never travel alone. Ideally, sub-teams of four members will travel together at all times. Some team members will also be able to use their cell phones in case of extreme emergency. A two-way radio will be given to each group so they can communicate with other groups. In case groups get separated or if there is an emergency, a central , accessible meeting location will be chosen every morning.Emergency Plan & Exit StrategyDescribe the evacuation plan for medical emergencies, weather or political unrest.In the case of individual medical emergencies, each team member will be able to use his or her emergency evacuation insurance (which will be purchased before traveling) to reach the nearest adequate medical facility. If evacuation is not possible, team members will be able to access the medical facilities at the capital (Ouagadougou), which is about a 5-hour drive away. For immediate medical attention, the medical facilities at Dissin would be within an hour’s reach of any of the villages, and is minutes walking distance from the town center. There are also adequate medical facilities in Dano that are between those of Dissin and Ouagadougou in terms of location. Team members are already familiar with the exact location of the Dissin and Dano medical centers.Evacuation insurance also could be used in case of weather, political unrest, or other emergencies that could arise. In such instances where the safety of the entire team could be compromised, the team will coordinate via cell phone or two-way radio, meet in Dissin, and immediately drive to the safest airport (likely either in Bobo-Dioulasso or Ouagadougou) from which they could leave the country.Determine whether there are any State Department Warnings for this country.There are no State Department Warnings for Burkina Faso.Determine whether there are any other safety concerns for traveling at this timeChances of contracting meningitis fever are highest during the drier part of the year, from January to June. The rainy season begins in in May, at which point Malaria becomes a major concern. Preventative medications will be taken by each travel member, and the community clinic has capabilities of testing for, and treating Malaria. Each traveling member will be asked to receive vaccinations against Yellow Fever, Typhoid, Meningitis, and Hepatitis A.

The clinic is walk-in only.The Peace Corps uses a clinic in Bobo-Diloulasso in southwest Burkina Faso approximately 2.5 hours away by car. It is called St. Leopold and although several doctors there have varying specialties, the Peace Corps mostly uses Dr. Yameogo, who practices internal medicine. The phone number from within Burkina Faso isThe capital, Ouagadougou, 5 hours away by car, has the most extensive medical facilities. One is a the Centre Medical-Social, which is a French Embassy Clinic. The number is It is located at Rue Nazi Boni, Ouagadougou.Project SafetyPlease refer to the Army Corps of Engineers Health and Safety Manual for any topics that are relevant to your trip.General guidelines for Electrical Work found at:Discuss what Personal Protective Equipment (PPE) you will need.When working with live electrical circuits, we will need to use insulating (e.g. rubber) gloves. Also, safety goggles will be required for any heavy drilling or sawing.Discuss what dangerous and risky situations are possible during your trip and how you will be ensuring everyone’s safety.Proper dress and precaution must be taken for the heat and construction safety. One major concern will be malaria from mosquitoes, and students could get bacterial or protozoal diarrhea, hepatitis A, and typhoid fever from the local water or food. Other major infectious diseases include schistosomiasis and meningococcal meningitis. All members traveling must get immunizations and be cautious of what is eaten within the community.
