"The Monterey Regional Water Pollution Control Agency claims to operate the world’s largest water recycling facility designed for raw food crop irrigation, using 25 pumping stations to treat 20 million gallons of wastewater every day. Pumping, treatment and conveyance are a few of the most expensive and energy exhaustive processes for regional municipalities, comprising more than 30% of their budgets, according to a case study provided by Candi Controls.
