Req 7a6 — Waste-Treatment Plant
7a6.
Make a trip to a waste-treatment plant. Write a report of more than 500 words about the soil and water and energy conservation practices you saw.
If you liked Req 6, this option brings it to life. A waste-treatment plant shows how a community removes solids, breaks down organic waste, and protects rivers or lakes from untreated sewage.
Look for screens, settling tanks, aeration basins, clarifiers, disinfection, sludge handling, odor control, and monitoring equipment. Also pay attention to energy use. Treatment plants often try to save energy with efficient pumps, process controls, methane recovery, or other upgrades.

What to Notice on a Plant Tour
These details make your report stronger
- What enters the plant: household and business wastewater, stormwater, or both
- What gets removed first: trash, grit, and large solids
- What the biological stage does: breaks down organic waste
- How the plant protects the environment: testing, disinfection, and safe discharge
A drinking water plant is the mirror image of this process: instead of cleaning used water for release, it prepares raw water for people to drink.
