Marana High School has a packaged waste water treatment plant, which presented problems. The Septic crew at Cummings Plumbing, Heating and Coolingconsulted with the original architect to complete the needed design changes for proper function. The system holds 72,000 gallons of product, which had to be removed, the plant was cleaned and numerous modifications were needed. The goal of the project was to add a valve which would allow the plant capacity to be cut in half during the summer, to keep the chemical process working as intended. All was done without major interruptions or delays.
