PSC 185.43(1)(1)
Every utility shall prepare and maintain a record of its utility plant. The records shall include a description of the unit of property, the year of its construction, and its location. They shall be in the form of a map or descriptive table.
PSC 185.43(2)
(2) Class AB utilities are required by the uniform system of accounts to institute a perpetual inventory of their assets known as continuing property records. A continuing property record system shall contain the following criteria and detail:
PSC 185.43(2)(a)
(a) The system shall be arranged by plant accounts as prescribed by the Uniform System of Accounts;
PSC 185.43(2)(b)
(b) All property units shall be described in sufficient detail to permit their identification and shall have location information to allow verification of their physical existence;
PSC 185.43(2)(c)
(c) All property units shall be identified with construction costs to establish their original cost for capitalization and retirement accounting;
PSC 185.43(2)(d)
(d) The age and service life of property units shall be calculable for depreciation studies. The original cost, description, and age of the property unit at retirement shall be converted into mortality records and permanently retained. (See s.
PSC 185.19);
PSC 185.43(2)(e)
(e) Source documents supporting the original cost and quantities of property units shall be preserved for a period of 6 years after the plant is retired. (See s.
PSC 185.19.) An exception is when a utility maintains approved continuing property records and permanent mortality records, then supporting documents need only be preserved for a period of 6 years after construction is completed. This provision meets commission requirements but may not satisfy other record-keeping needs;
PSC 185.43(2)(f)
(f) Maps may be part of the continuing property records if they contain the description of the unit, its location, and the year of its construction. For maps to become the Continuing Property Record, the units shall be referenced to their original cost.
PSC 185.43(3)
(3) A utility may apply for a waiver from any portion of subs.
(1) and
(2). Such application shall state the paragraphs to which a waiver is requested. Also, the utility shall provide the reasons it cannot or shall not have to comply with subs.
(1) through
(2) (f) and the impacts such a waiver would have on the utility's ability to maintain usable continuing property records, if any.

PSC 185.65 Accuracy requirements for meters. PSC 185.65 Note
Note: See AWWA Standards C-700 (Positive Displacement Meters), C-702 (Compound Meters), and C-701 (Turbine Meters).
PSC 185.65(2)
(2) Positive displacement meters shall have a percent registration between 98.5 and 101.5 within the range of normal test flow limits before being placed in service. In addition, new meters shall have a percent registration at the minimum test flow between 90 [95] and 101.5. In all other cases, the percent registration shall be between 90 and 101.5 before being placed in service. These requirements, in addition to flow, are shown in the table below.
PSC 185.65 Note
Note: It is the intent of the commission that new meters have an accuracy limits percent between 95 and 101.5.

See PDF for table 
PSC 185.65 Note* Section
PSC 185.73 (3) provides that at this flow rate the test quantity may be reduced to that equivalent to one-half revolution of the test dial. For the typical 5/8-inch meter the minimum test quantity would, therefore, be 5 gal. or 1/2 cu. ft.
PSC 185.65(3)
(3) Compound meters shall have a percent registration between 97 and 103 throughout the range of normal test flow limits. At flows within the change-over flow range, the percent registration shall not be less than 90%.
PSC 185.65(4)
(4) Turbine meters shall have a percent registration between 97 and 103 throughout the range of normal test flow limits and a percent registration of at least 95% at the minimum test flow.
PSC 185.65(5)
(5) For meter installations with remote reading devices the above accuracy requirements apply to the metering accuracy of the complete installation.

Each utility furnishing metered water service shall own or provide, through contract or otherwise, adequate equipment and facilities to provide for testing all of its water meters in compliance with this chapter.
PSC 185.71(2)
(2) The meter testing facility shall, to the extent practical, simulate the actual service condition of inlet pressure and outlet pressure. It shall be provided with the necessary fittings, including a quick-acting valve for controlling the starting and stopping of the test, and a device for regulating the flow of water through the meter under test within the requirements of this chapter.
PSC 185.71(3)
(3) The overall accuracy of the test equipment and test procedures shall be sufficient to enable the testing of service meters within the requirements of this chapter and regulations. In any event, the inherent overall accuracy of the equipment shall permit tests with an overall error of not to exceed 0.5% at normal test flows and 1.0% at the stated minimum test flow.
