  1. Update Variable Naming Guide (by semesters end)
    • Update naming guide based on programs currently being used. Each variable should be complete with the definition, where it is used, and where it is calculated.
    • Team members: Reiko
  2. Edit Flocculation program (By end of Feb)
    • Rewrite program from an energy dissipation approach.
      •  Overall flocculation potential of the flocculator is now based on Θ*ε^(1/3) rather than on G*Θ.
      • We might need to increase the flocculation potential for future plants to improve performance under low turbidity conditions.
    • Correct placement of baffles for AutoCAD drawing. The algorithm needs to determine where the baffles start based on the entrance tank.
    • Add checks for port hole placement vs water level and baffle placement vs port hole.
  3. Edit the Sedimentation Slopes program (End of Feb)
    • Correct arbitrary assumptions - velocity ratio.
    • Automate the program to check for reasonable values--add calculations that a reviewer can use as checks.
      • Compare average velocities in channels, ports, manifolds, and orifices--these should be similar.
    • Update slopes program variables to incorporate triangular and trapezoidal geometries in the other programs.
      • Create a critical design parameter that will be the maximum length of the sedimentation tank as a function of the inlet manifold geometry.
      • Inlet manifold geometry will be determined based on the length and velocity through the sedimentation tank.
    • Changes made for 4 Communities need to be incorporated into the general program.
    • New sludge drain design for the sedimentation tank.
    • Incorporate floc weir design upon confirmation that it works.
  4. Update AutoCAD method of drawing sedimentation tank and floc tank  (Complete by end of March)
    • Draw the sedimentation tank so that it is possible to see order of construction.
      • Begin with the rectangular tank, and then fill in the additional items (bottom slopes containing sludge channel, drop tubes, sludge weir, sludge port plates, manifold sloped plates).
      • Group related objects so they can easily be manipulated in the CAD drawing
        • For example, group all plate settlers in each sedimentation tank, group baffles similarly.
    • Add construction details including ledge that supports the plate settlers, inlet manifold plates, sludge drain channel, sludge drain plates, sedimentation tank inlet drop tubes, inlet channel port covers, etc.
    • Check AutoCAD dimensions to make sure the plant is being drawn correctly
    • Make sure code includes geometry-specific dimensions for the Sedimentation Slopes program.
    • Make sure all components draw correctly for Sedimentation Tank--location of plate settlers, exit launder.
    • Incorporate change from sludge pipe to sludge channel.
    • Inlet pipes into slopes need to be changed to concrete voids--no longer pipes. Make sure to change corresponding layer.
  5. Update Algorithm Documentation for MathCAD programs (by end of semester not to begin until programs are complete)
    • Make sure rendered images are shown with dimensions.Team members: Reiko
    • Make sure variable list is updated.Team members:
    • Edit for clarity. Each member needs to review.
  6. Organization (by April 1)
    • Programs for each design need to be filed (possibly on the Wiki) for easy review at a later point.
    • Detailed dimensions of each plant need to be posted on the Wiki with AutoCAD drawing.
    • Document the design of the existing facilities (as built) in a table format.
      • Should include tank dimensions, residence time for flocculator, and Vup and Vc for sedimentation tank.Team member: Reiko
  7. AutoCAD Documentation (ideally by semesters end, might get pushed to next semester)
    • Update documentation for current programs--make sure variables are correct.
    • Finish adding pictures to Sedimentation Tank documentation page.
  8. Work on plant designs as presented throughout the semester (Gracias by March 15, Ecuador by March 1)
    • Create a series of designs and post them on the wiki to demonstrate automated design capabilities. Show the effect of changing different user inputs.Team members: Reiko
    • Complete Gracias design.
    • Ecuador university pilot plantTeam members: Reiko and Heather Hunter
    • Pakistan pilot plant
  9. Develop a plan to create the detailed documentation that the partner organization needs to build the facilities (rough draft with Gracias design, final with semesters end)
    • Materials list
    • Fabrication method for the plate settlersTeam members: Reiko
    • Possibility to add these details to AutoCAD?
    • Greater design detail for new partner organizations especially since it is possible that an AguaClara plant will not be on site.Team members: Reiko and Heather Hunter
  10. Provide continuity training and recruitment (on going)
    • Recruit students for summer program.
    • Train students who will be continuing on the design team during the summer and next fall.
