The Quatro Communidades plant is serving these 4 communities: Los Bayos, Rio Frio, Las Jaguas, and Aldea Bonito. By design, the plant is relatively smaller - the plant flow rate is 100.4 gal/min. However, this plant will be the first plant to include the sedimentation tank slopes (inlet triangular manifold), and exit channel, and a hoper for the floc blanket. each sedimentation tank has 2 inlet slopes. Given the specific energy dissipation rate, velocities for the entrance channel, connections to the manifolds, and manifolds, are all constrained to not break up flocs and minimize the floc sedimentation. Single width sedimentation tanks were used for the design, and were made to be shallower than previous ones.
