What should be done to vent openings on reservoirs and clear wells?

Venting openings on reservoirs and clear wells are essential for the proper functioning of water systems. Screening these vent openings is crucial to prevent contamination from external sources, such as insects, debris, and other pollutants, while still allowing for the necessary exchange of air. Proper ventilation helps alleviate pressure buildup, which can occur due to temperature changes or water level fluctuations, thus ensuring the structural integrity of the reservoir.

Screening serves as a barrier that allows air to flow in and out but keeps harmful contaminants from entering the water supply. This practice not only enhances water quality but also contributes to the overall safety and reliability of the water distribution system. Therefore, it is critical to maintain these vent openings with screens to promote sanitary conditions and protect public health.
