To me it's surprising how many people have no idea
Where their drinking water comes from or where it goes after they flush the toilet?
When I open up a faucet I taste and smell the water to make sure that it's up the standards. Yeah, I'd monitor that
The hill engineering was formed in 1898 it's one of the oldest engineering firms in the country
It was acquired by GPI in 2016, hill engineering pretty much does the same thing that we're doing for GPI today
We do water and wastewater
Treatment plants they've built a number of facilities throughout western PA & western NY
This was the original treatment plant built in 1903
It was pretty much a glorified septic tank called an Imhoff tank so it treated all the wastewater in the town
It was just one large tank and in the last hundred years. We've gone from this to all this
Wastewater is collected in sanitary sewer pipes
Conveyed to a central location where the wastewater treatment plant is. One basic type of treatment process is what we call activated sludge
Which is what we have here at Northeast. We're at the Northeast, Pennsylvania
site one wastewater treatment plant
We're at the head end of the plant so when you flush the toilet
It comes into this tank. This is the first part of the process when we look at wastewater capacity
We look at flow and organic loading it treats 30,000 pounds per day of B.O.D.
Which is an equivalent service population of about a hundred and twenty-five thousand.
We have aeration tanks where we add air to break down the the organic waste through
Bacteria that we grow in those tanks the next step is here at the wastewater aerated lagoon
We have about four million gallons of wastewater under aeration in these aeration tanks
We grow bacteria that break down the wastewater and remove the organics we settle out that bacteria and clarifiers
The water is pumped into this clarifier tank
this is about a hundred foot diameter tank and we settle out the wastewater solids we take the settled sludge and send it to a
Digester to break it down further we pump those solids to anaerobic digestor where with the aeration
further breaks down the solids prior to dewatering there's about 700 thousand gallons of
solids under aeration in these two tanks
Then that digested sludge is then dewatered and the solids are typically sent to a landfill or maybe land applied
This is our sludge dewatering building the solids from the aerobic digester are pumped to here and we dewater
Those solids into a cake that goes to the landfill
We have a centrifuge and a belt press in this building that dewater the solids we send a 28 ton
Tri-axial full of dewatered sludge to the landfill about every three hours
GPI is up to speed with all the latest treatment technology including meeting tertiary standards familiar with all the state and federal
regulations pertaining to water and wastewater
