Which of the following is part of the start-up procedures for a seasonal system?

Disinfection and distribution system flushing is a critical part of the start-up procedures for a seasonal water system. When a seasonal system comes back online after a period of inactivity, it is essential to ensure the quality and safety of the water supply.

Flushing the distribution system helps to remove any stagnant water that may have degraded in quality during the off-season. This process also aids in clearing out any sediment or debris that may have accumulated in the pipes. Disinfection is equally important as it eliminates any pathogenic microorganisms that could pose health risks to consumers. Together, these steps help ensure that the water being delivered is safe, meets regulatory standards, and is suitable for consumption.

While filtration and chemical analysis, sample collection from previous months, and public notification are important in the broader context of water system operations and management, they do not specifically address the immediate concerns of ensuring safety and quality during the reactivation of a seasonal system as directly as disinfection and flushing do.
