Mangiang Water Initiative

This project aims to provide clean water to underserved communities in Papua New Guinea through the implementation of water initiatives. The team will be responsible for logistics, project management, design, community impact communications, and tank stand design. The project will focus on existing wells, previous solar pumping projects, and technical advice from Neil Higa.

  19. Assumptions

  20. Structure

  21. Connections

  22. Footings

  23. Construction At Unitech - Cut members to size, drill holes, cut slots - Weld plates to beams - Weld L-brace to beams - Assemble two frames Truck materials to Mangiang At Maniang site - Dig holes for 4 column bases - Place frames in holes and lift - Bolt the X-braces in place - Bolt the 2 remaining perimeter beams - Bolt the interior beams - Widen the base holes - Make footing forms - Start mixing concrete - Insert rebar to column - Add concrete -Cover with tarp for several days -Place and secure tank with chains/straps

  24. Hydraulic System

  25. Design Overview • Population Serving: 500 people in village center • Daily Demand/Person: 20 L -Drinking, cooking, sanitation • Total Demand: 10,000 L/day • System: Non-battery powered, will pump when appropriate solar insolation • Pump/Controller: Lorentz PS200 HR-14 • Storage Tank: 9000L Tuffa Tank • Assumed Pumping Day: 5 hrs (conservative) • Design Pumping Rate: 33.3 L/min (9 gpm)

  26. Pump/Controller • Lorentz PS200 HR-14 • Helical Rotor Submersible Pump • PS 200 Controller • Controls Pump System • Two inputs: Well Probe (Dry Running Protection) + Float Switch (tank) • Adjustable Pump Speed • Time Delays for Low-Water Level, Full Tank, Insufficient Sun • Indicator Lights: System Power, Pump On, Source Low, Tank Full, Insufficient Sunshine, Pump Speed • Over Current Protection • Clear Casing to be covered
