What must be done to all openings of a septic tank?

1. Left open

2. Sealed

3. Screened

4. Valved

The correct answer is: Sealed

Sealing all openings of a septic tank is essential for several key reasons. First, it prevents contaminants and foul odors from escaping into the environment, which is crucial for maintaining public health and environmental safety. Septic tanks can harbor harmful bacteria, viruses, and chemicals, and sealing the openings helps to contain these threats. Moreover, sealing openings protects the system from inflow of groundwater, which could dilute the wastewater and disrupt the operation of the septic system. Keeping the system sealed also helps to ensure that no debris, leaves, or unwanted materials can enter, which might lead to clogs or malfunctions in the treatment process. While options like leaving the openings open, screening, or valving are not suitable practices. Openings must be properly sealed to ensure a functioning and safe septic system, aligning with best practices and regulatory standards.
