- MathCAD Automated Materials List (Adela)
- Fixing Small MathCAD code issues (Adela & Reiko)
- Switch programs that refernce nominal diameters to calculate areas, hopper drain, width to depth ratio for sed drain. (Adela)
- Valve sizes: sludge drain, hopper drain?, floc drain (Adela)
- Flocculator design, after you figure out how many baffles that are ideal for a channel, figure out how many actually fit and put them in uniformly. Ports that go under the walls? Do the engineers care? That affects how the tank is drained (Reiko) (Reiko)
- Floc Drain Algorithm (Reiko)
- Sludge drain width needs to be adjusted (Reiko)
- Check needs to be added so that the length below the slope is at least 2.5cm
- Gap between slope plates and wall needs to be calculated (Reiko)
- Number of ports/plates in sed tank are overestimated (why?) The number of ports/plates were calculated based on the max sed length. Changed to be calculated based on the actual length now.
- Plates stay at 30cm
- Slope plate length need to be adjusted so the opposite corner rests against the wall (the length will decrease) Floc Drain Algorithm (Reiko)
AutoCAD
(Heather R, Sara & Heather H)
- Update Code with MathCAD variable Changes (could be a task spilt between people taking the programs below). (Heather R & Heather H)
- Check and Debug Flocculator Program(Heather R)
- Check and Debug Entrance Tank Program (Heather H)
- Debug basic Sed tank program (just the outer tank walls (exclude the inner pieces)(Sara)
- Scripts to Draw Drain Valves
- Drop chimneys
- Add 15cm false bottom
- Slopes and the rest of the fill are then drawn as one element
- Lamella need to be adjusted to incorporate pipe frame
Later Tasks
- Stream Line Sed tank code into modules
- Change pipe Drains into Channel Drains
- Change Drop pipe chimmmeys connecting inlet channel to sed manifolds to rectanglular channels
- Adjust the sed bays program to build dividing walls and be accurate
...
- Drain to have minimum dimension of 12cm (OD 4" pipe = 12cm)
- Exit pipe that connects to valve needs to fit under the drain plate
- 3" gate valves are used in Honduras
- Check that 3" or 4" pipe will fit without alteration under the drain
- Count number of Valves needed
- Walls between bays are 15cm thick
- Send drawing of new drain cover
- Floc Ports are cut in the tops of the channel dividing walls
- Lamella Pipe Frame Table 1.5" pipe sitting on ledge, possible concrete frame instead
- Thickness of floc baffles: 4cm
- Baffle dimensions/area needed to determine thickness (sent to Tamar)
- For Gracias:
- AutoCAD drawings for all 3 designs--concrete layout OK
- Chemical Storage Tank Dimensions
- For Altima:
- Send out Design
- Complete Design for Alquteca (same as 4 communities)
