Pressure and Flow Analysis Through EPANET Open source software package for hydraulic simulation of water distribution networks Used to determine impact of system improvements on system pressure To complete the projects, the team had 7 working days and worked 8-12 hours each day. The team worked simultaneously on several projects; some were standalone, while others affected the overall project critical path. As tasks were completed, labor was often shifted to ensure completion of the highest priority projects, listed below: Lot 1 Connection Police Tank Repair High Pressure Zone No. 1 Tank Garbage Shed Overview Water Distribution System Water Storage Tank Design Schedule Pitt Humanities, Engineering and Design Club (Spring 2014) Engineering in Panama: Kuna Nega Water Infrastructure Improvements Garbage Shed Foundation Design School tank piping diagram Rationale Kuna Nega school previously stored refuse in hallways To improve cleanliness and reduce odor, an offsite storage area was required. Design Objectives Produce initial contour map of the hillside. Displace 100 cubic feet of soil to level the work site. Improve Slope Stability factor of safety from 1.19 to Analyze design of foundation Results This will give the school 700 cubic feet of garbage storage. This will reduce the amount of litter in the village and improve the quality of living. Foundation design is adequate Lot 41 Water Storage Tank Lot 41 Tank Design Specifications: Square tank with 12’x12’ inner dimensions Actual storage capacity of 11,500 gallons Composite tank with concrete masonry walls No. 1 Tank Design Revisions Review initial designs Compare designs to existing structure in Panama Monitor construction of structural components while on site to ensure proper installation No. 1 tank, section A-A Construction of tank No. 1, taken CMU block construction is preferred by the local labor A square tank is more constructible than a circular tank when using CMU block Pre-implementation when Panama main line is shut off Post-implementation when Panama main line is shut off PumpLiberty FL150 Flow rate (gpm)41 Operating Head (ft)82 Total head loss (ft)8 Shut off head (ft)110 System and pump curves with operating characteristics Project Manager: Blaise BuchaConstruction Managers: Neal Daley, Jesse Newman-Evans, Mike Poole Water Resources Team: Julie Shearer, Matthew Weschler Structural Team: Caleb Angle, Mike Barnes, Phil Karanovich Geotechnical Team: Nikil Grama, Chris Mautino, Kathleen Staub Supply Yard School Tank No. 1 Tank Police Tank Lot 1 Lot 41 Garbage Shed Stream High Pressure Zone Panama City Water Main Project summary: Creation of a high pressure zone and design of a future 10,000 gallon tank at the highest point in the community to supply water to the area not serviced by the existing tank Continued construction of a 25,000 gallon storage tank to supplement the existing tank Installation and replacement of valves to improve system efficiency and simplify maintenance Construction of a garbage shed foundation for the Kuna Nega school Project Background: The Panama City water main that supplies Kuna Nega is periodically shut off for up to 36 hours. The existing 10,000 gallon storage tank can only provide backup supply for 10 hours. Part of the community that lies at a higher elevation than the existing tank receives no pressure when the Panama City water main is shut off. Location of projects in Kuna Nega Results High Pressure Zone pressurized during periods when the Panama City water main is shut off Entire community pressurized according to EPANET model Lot 41 Tank design to be implemented next semester Design Implementation Installed submersible pump in the school tank to pressurize High Pressure Zone Connected Panama City water main to Lot 1 Connected police station storage tank to distribution system Installed: 700 feet of PVC pipe, 8 ball valves, 4 check valves and 4 air release valves Unexpected valve challenge Lot 41 tank elevation view Lot 41 wall detail Gantt chart of work completed to D rendering of garbage shed footer Section view of forces on retaining wall and slab
