Per engineering Bulletin No. 10, Chapter 5, D.3. AIR RELIEF VALVE.
An air relief valve should be provided in all air-charging pneumatic systems. The air relief valve
shall be located at the low water level setting of the tank, unless alternative design concepts are
provided. This function prevents excessive air from entering the distribution system in the event
the water seal is lost. |

Per engineering Bulletin No. 10, Chapter 6, E.9. VENTS.
Finished water storage units shall be vented. Overflows shall not be considered as vents. Open
construction between sidewall and roof is not permissible. Vents on all storage units:
a. Shall prevent the entrance of surface water and rainwater.
b. Shall exclude birds and animals.
c. Shall exclude insects and dust as much as this function can be made compatible with
effective venting. Must be screened to prevent insects and small birds in search of water
from entering the tank and contaminating the water. |

except for properly constructed vents, manholes, overflows, risers, drains, pump mountings,
control parts or piping for inflow and outflow. Other provisions are:
a. Any pipes running through the roof or sidewall of a finished water storage structure
(metal tank) shall be welded or have proper gaskets.
b. Openings in the roof top designed to accommodate control apparatus or pump columns
shall be curbed and sleeved with proper additional shielding to prevent the access of
surface or floor drainage into the storage unit |
