True or False: Operators must maintain records of water usage.

Maintaining records of water usage is crucial for operators as it helps ensure compliance with regulations and allows for effective management of water resources. Operators are responsible for tracking water consumption to identify trends, assess system performance, and detect potential issues such as leaks or inefficiencies. Accurate records assist in water conservation efforts, monitoring for growth patterns, and ensuring that usage remains within permitted limits. This data is also vital for reporting requirements to regulatory authorities and can be crucial in situations where water quality or supply issues arise.

While the other options suggest limitations or exceptions to record-keeping, these do not align with the regulatory expectations for operators. Maintaining comprehensive records without exception contributes to the overall reliability and accountability of water management practices.
