A Day with the Strong Waste Program

The treatment of wastewater from restaurants, apartment buildings, commercial businesses, car washes, industrial plants, breweries, hair salons, printers, and similar businesses that have wastewater discharges different from the typical household is a significant expense for DPU, which can recover some of the costs associated with treating wastewater from industrial users through the Strong Waste Surcharge Program. The program measures concentrations of biochemical and oxygen demand, suspended solids, total nitrogen, and total phosphorus in annual random wastewater samples from these types of customers and adds surcharges to their utility bill. The tests involve visiting all those businesses at least once a year and taking samples over a 3-4 day period.

A lot of toilet paper in this one. The hose goes in to collect a sample.

Thanks for the demonstrations on what you do, Mr. Newton!
