Today PPI employees had a Tour of the Wastewater Treatment Plant at Cedar Village. They learned the details about the plant, starting with the EQ (Equalizer tank ) to the digester tank, Aeration tanks, Clarifier, Chlorine, and De-Chlorine, and finally to the V box and the creek. Theywalked the plant and had a chemistry class at the lab.Thank you, Spencer! Evergreen Village resident of the month! Emerson Farmer’s Market
