The Cuatro Communidades design was smaller than other recent designs completed. Single width sedimentation tanks were used for the design, and were made to be shallower than previous designs. This plant will be the first to be designed to include the sedimentation tank slopes, and an exit channel, and a hopper for the floc blanket. Details of the design can be found below.

We began the semester trying out new set-ups for the Gracias community which required a flowrate much higher than previous designs. Quanititatively, the flow rate for our plant designs have increased from 500 gal/min in Marcala to 1600 gal/min in Gracias. The design results can be seen below.
It Due to the large flow rate, it was ultimately decided that Gracias would have a triple width sed tank. The variable widths of the sed tank will later be automated to account for higher flowrates. Experimental setups are included below that discuss the different alternatives we considered.
