Hi Lee,

Just sending you some information on the diffuser system the City purchased to add aeration to Lagoon #1. We will obviously need to sit down and go through the specifics with Jason, the Lead Plant Operator. We purchased a 6 diffuser system capable of 11 surface Acres. The pond typically operates at 9-ft and recently confirmed using GIS mapping lagoon #1 to be to be 11.91 Ac at that elevation. However, we are primarily focused on the build of solids at the inlet on the west end.

Just want to get the ball rolling.

Thanks,
