Section R309-540-3 - Definitions
Current through Bulletin 2024-18, September 15, 2024
Definitions for certain terms used in this rule are given in Rule R309-110. Terms not defined in Rule R309-100 but used in Rule R309-540 include those defined in Subsections R309-540-3(1) through (8).
(1) "Air-Over-Water Hydropneumatic Tank" means a pressure tank with a single chamber in which air and water are in direct contact. Water pumped into the tank compresses the air above it.
(2) "Bladder Hydropneumatic Tank" means a pressure tank that has a bladder in the bottom section of the tank that holds water under pressure. Water pumped into the bladder compresses the air in the upper section of the tank.
(3) "Booster Pump" means a pump that increases pressure in a water distribution system or supplies water to an elevated storage tank. The water supplying a booster pump is provided by a water storage tank or a water distribution line.
(4) "Diaphragm Hydropneumatic Tank" means a pressure tank with a fixed, flexible diaphragm that separates water in the lower section of the tank from air in the upper section. Water pumped into the lower section compresses the air in the upper section of the tank.
(5) "NSF/ANSI 60" - the joint National Sanitation Foundation/American National Standards Institute 60, Drinking Water Treatment Chemicals - Health Effects
(6) "NSF/ANSI 61" - the joint National Sanitation Foundation/American National Standards Institute 60, Drinking Water System Components - Health Effects
(7) "Pump Station" means a structure housing pumps and associated piping, valves, and auxiliary equipment.
(8) "Service Factor" - A multiplier which, when applied to rated power, indicates a permissible power loading that may be carried under the conditions specified for the service factor.
