R309. Environmental Quality, Drinking Water.
R309-540. Facility Design and Operation: Pump and Hydropneumatic Pressure Facilities.
R309-540-1. Purpose.
The purpose of this rule is to provide specific requirements for pump stations utilized to deliver drinking water to facilities of public water systems. It is intended to be applied
in conjunction with Rules R309-500 through R309-550. Collectively, these rules govern the design, construction, operation, and maintenance of public drinking water system facilities.
These rules are intended to assure that facilities are reliably capable of supplying quantities of water which consistently meet applicable drinking water quality requirements of Rules
R309-200 and R309-510 and do not pose a threat to general public health.
R309-540-2. Authority.
This rule is promulgated by the Drinking Water Board as authorized by Title 19, Chapter 4, Safe Drinking Water Act, Subsection 104(1)(a)(ii), and in accordance with Title 63G, Chapter
3 Utah Administrative Rulemaking Act.
R309-540-3. Definitions.
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.
