Team Vision for Preliminary Detailed Design Phase

Vision

Our expectations for this phase is to focus on further development of our systems design proposal, with specific attention being made to our high-risk components, the rope pump and water wheel. We plan on expanding upon our feasibility studies for both our high-risk components as well as further development of our architecture and development of the support system for the filter and PVC piping. We also expect to further our prototyping of nitrate cycling by beginning to use live goldfish in our tests and monitor their vitality. By the end of this phase, we plan to have completed feasibility studies of our rope pump and water wheel system and have begun implementing it on our actual system by applying the knowledge we gain through this phase on further developing our systems architecture. We also plan on establishing a preliminary BOM and further develop our project test plan. Through adherence to identified project risks and maintenance of the project deadlines and deliverables, we will successfully complete the preliminary detailed design phase.
