What’s in wastewater? Waste  human feces and urine  food from sinks  soaps and other cleaning agents  runoff from streets and lawns  industrial discharges

What’s in wastewater? Water  lots of it!  Urinal - 1 gallon per flush  Toilet - 4 gallons per flush  Shower - 20 gallons per use  Overall - 55 gal/person/day

It’s mostly water! There are about 500 parts of waste in every 1 million parts of wastewater; that’s 500 ppm. It’s like trying to find this class at a sold out Packers game! H2OH2O

So what’s the problem? P SNOT: it snot a pretty picture!

Where does it go when you flush the toilet? This is really not something I’ve given a lot of thought to.

It’s a 24/7 thing! The Portage Lake Wastewater Treatment Plant was built in and cost$20M. On average, the plant receives 2.8 MGD of raw wastewater with peak flows >10 MGD. If there are 7.48 gallons in 1 ft 3, how many days of sewage flow would it take to fill Hancock H.S. to the roof? How much?

It’s a 24/7 thing! The Portage Lake Wastewater Treatment Plant was built in and cost$20M. On average, the plant receives 2.8 MGD of raw wastewater with peak flows >10 MGD. The average daily flow to the Portage Lake Treatment Plant would fill the EERC to the roof in 4 days. How much?

Then it snot a problem! P SNOT: it snot a pretty picture!

How do we treat it? Then it snot a problem! Bacteria Protozoa

And where does it go from here? Treated effluent from the Portage Lake Wastewater Treatment Plant is discharged to Portage Lake … an important recreational resource for all of us.
