Why treated waste water is collected in guard pond?

Treated wastewater is collected in a guard pond to allow for further settling of any remaining particulates and to provide additional treatment through natural processes, such as filtration and microbial activity. This holding area also serves as a buffer to manage fluctuations in water quality and quantity before the water is discharged or reused. Additionally, the guard pond can help prevent potential contamination of surrounding water bodies by ensuring that only adequately treated water is released. Overall, it acts as a critical step in ensuring environmental protection and compliance with regulatory standards.
