== Description of final project == The final solution implemented at Redwood Coast Montessori, the P.V.C. System, was chosen because it meets the stated criteria and satisfies the client's needs and specifications best. The P.V.C. System follows the basic design of most of the other considered alternative solutions with a few variations namely the storage tanks, the conveyance components, and the filtration mechanisms. It is comprised of mostly upcycled materials, with the exception of the PVC piping. Rainwater flows down the school's sloped roof and travels through the existing gutter system into a first flush diverter. This component collects the first bit of rain containing most of the contaminants then, when it is full, the rest of the water is diverted down another section of the piping through screens and into the 55 gallon food drums. Once the students are ready to use the collected rainwater a supervisor must unlock the system and the spigot can be turned on to allow water to flow out. Materials such as the food drums, PVC piping, and cinderblocks are up cycled or purchased cheaply, minimizing our costs. === Costs === The following charts illustrate Team RainBeaus' costs analysis with respect to both time spent designing the system as well as money spent on creating the system. <gallery> File:AutoCadEntirePVCSystem.PNG|thumb|Diagram of the P.V.C.
