Current through Register Vol. 54, No. 28, July 13, 2024
(a)
Variations in pressure.
The utility shall maintain normal
					 operating pressures of not less than 25 p.s.i.g. nor more than 125 p.s.i.g. at
					 the main, except that during periods of peak seasonal loads the pressures at
					 the time of hourly maximum demand may be not less than 20 p.s.i.g. nor more
					 than 150 p.s.i.g. and that during periods of hourly minimum demand the pressure
					 may be not more than 150 p.s.i.g. A utility may undertake to furnish a service
					 which does not comply with the foregoing specifications where compliance with
					 such specifications would prevent it from furnishing adequate service to any
					 customer or where called for by good engineering practices. The authority of
					 the Commission to require service improvements incorporating standards other
					 than those set forth in this subsection when, after investigation, it
					 determines that such improvements are necessary is not hereby
					 restricted.
(b)
Pressure
					 gauges.
Within 2 years after the effective date of this section, each
					 utility shall obtain one or more recording pressure gauges for each separately
					 operated pressure zone for the purpose of making pressure surveys as required
					 by this section. These gauges shall be able to record the pressure experienced
					 on the zones and shall be able to record a continuous 24-hour test. Each
					 utility serving 1,000 or more customers or 1,000 or more customers in any
					 separately operated zone of a multi-zone utility shall maintain one or more of
					 these recording pressure gauges in service at some representative point or
					 points in each of the pressure zones of the utility.
(c)
Telemetering.
An utility
					 may make the pressure surveys required by this section by means of telemetered
					 information electronically transferred to printed copy instead of using
					 recording pressure gauges.
(d)
Pressure surveys.
At regular intervals, but not less than once
					 each year, each utility shall make a survey of pressures in its distribution
					 system of sufficient magnitude to indicate the pressures maintained at
					 representative points on its system. The surveys should be made at or near
					 periods of maximum and minimum usage. Records of these surveys shall show the
					 date and time of beginning and end of the test and the location at which the
					 test was made. Records of these pressure surveys shall be maintained by the
					 utility for a period of at least three years and shall be made available to
					 representatives, agents, or employes of the Commission upon request.
