What is the typical pH range for domestic wastewater?

Explanation:
Domestic wastewater is kept near neutral by buffering substances in the waste and water, which helps the biological treatment processes work effectively. This buffering maintains a pH around 6.5 to 8.0, a range that supports microbial activity and reduces corrosion risks. If the pH were much lower, the wastewater would be acidic and could harm treatment microbes and infrastructure; if it were much higher, the alkaline conditions could also stress the treatment system. So, the typical range you’d expect is about 6.5 to 8.0.
