1. Build another prototype possibly working with Hancock Precision who anodized and engraved it. They said they could build the whole thing for us but it would be rather expensive. Alternately work with the CEE shop to fabricate a new unit.
2. Figure out a good way to do the constant head tank for larger flow rates. It requires a bigger float/float valve.
3. Better Float. Some of the floats in Honduras move around excessively because of a lack of a heavy enough counterweight and because of poor entrance tank design. Explore options for better floats including buoys and floats that are shallow (more like a cake pan).
4. Anodizing didn't work great, because it was turning purple. Either figure out why it changed color so it can be prevented or paint it. Assess the durability of the anodized surface in a wet environment.
5. Develop a better method to zero the constant head tank - minor height adjustments to the lever or constant head tank were difficult and cumbersome.
6. The lever arm is big and might not fit in all the plants (This may be fixed by the better entrance tank geometry in the future)
7. Figure out if we can build the dosing tubes directly to specifications and expect them to work. This would minimize calibration time. The main concern is the dosing tube length
8. Create a better manifold system that is chemical resistant.
9. Document how all of this is to be done in clear concise product data sheets. Right now this knowledge is in David, Andrea, Rudy, Tim and Paul's heads' not written down anywhere. This could include documentation for fabrication and calibration.
10. Figure out retrofits for existing plants.
11. Determine how the doser systems should be fabricated in the future. Should they be produced and then sold by AguaClara LLC or should they be produced locally in each country?
12. Further performance testing.

Small Scale Plant Model

Understanding the layout and processes of AguaClara plants can be difficult if one has never seen a plant.  This team will design and create a small scale plant that can be used to demonstrate how the plant is laid out, where each process takes place and how it can be taken apart for cleaning.  Potential donors and partners, in particular, will benefit from the small scale plant as they will be able to more easily understand the plants and thus give AguaClara more money to provide clean water.

• Design and construct a small scale plan that can be used to present the AguaClara design.
• The final product should look like a model from the design tool.
• Include labels and features to distinguish between different processes in the plant. 
• Be able to take up square footage of a laptop and be easily portable.
• Can be taken apart in the same way as a full scale plant.
