Tours of our facilities are a great way to learn about what happens after you flush!

Our 90-minute outside walking tours let you experience the sights, sounds – and smells – of wastewater treatment. On a tour of our facility you will learn:

Learn the basic concepts of how wastewater is treated. 
See how microbiology, chemistry, physics and environmental science link to important environmental impacts & issues. 
Learn our responsibilities for the household products & chemicals that we use.

Here’s a sneak peek of our tours:

1 The tour begins at the headworks where untreated wastewater enters the Robert W. Hite Treatment Facility. The wastewater goes to bar screens to remove objects ranging from children’s toys to false teeth. Wastewater then goes to grit basins and primary clarifiers to remove solid waste. 

2 Next, it’s on to aeration basins where millions of microorganisms digest the organic waste remaining in the water. The wastewater goes to secondary clarifiers where the microorganisms clump together and settle to the bottom. After further processing to kill harmful organisms, these solids will go to enrich Colorado farmland. 

3 The tour proceeds to the chlorination and dechlorination processes and the outfalls. This is where the cleaned wastewater pours into the South Platte River. It’s easy to see the difference between the raw wastewater that came to the facility and the treated water as it leaves. 

4 The final stop of the tour takes visitors to the cogeneration building where methane gas from the solid digestion process is used as fuel to make enough electricity to power almost 5,000 homes!
