A water conservation plan for a wholesale water supplier shall provide information, where applicable, in response to each of the following paragraphs.

1. (1) Minimum requirements. All water conservation plans for wholesale water suppliers shall include the following elements:

   1. (A) a description of the wholesaler's service area, including population and customer data, water use data, water supply system data, and wastewater data;
   2. (B) specification of conservation goals including, where appropriate, target per capita water use goals for the wholesaler's service area, maximum acceptable unaccounted-for water, the basis for the development of said goals, and a time frame for achieving those goals;
   3. (C) a description as to which practice(s) and/or device(s) will be utilized to measure and account for the amount of water diverted from the source(s) of supply;
   4. (D) a monitoring and record management program for determining water deliveries, sales, and losses;
   5. (E) a program of metering and leak detection and repair for the wholesaler's water storage, delivery, and distribution system;
   6.

If the customer intends to resell the water, then the contract between the initial supplier and customer must provide that the contract for the resale of the water must have water conservation requirements so that each successive customer in the resale of the water will be required to implement water conservation measures in accordance with applicable provisions of this chapter;
   7. (G) a reservoir systems operations plan, if applicable, providing for the coordinated operation of reservoirs owned by the applicant within a common watershed or river basin.

(H) a means for implementation and enforcement, which shall be evidenced by: a copy of the ordinance, rule, resolution, or tariff, indicating official adoption of the water conservation plan by the water supplier; and a description of the authority by which the water supplier will implement and enforce the conservation plan; and
   9. (I) documentation of coordination with the Regional Water Planning Groups for the service area of the wholesale water supplier in order to insure consistency with the appropriate approved regional water plans.

2. (2) Additional conservation strategies. Any combination of the following strategies shall be selected by the water wholesaler, in addition to the minimum requirements of paragraph (1) of this section, if they are necessary in order to achieve the stated water conservation goals of the plan. The commission may require by commission order that any of the following strategies be implemented by the water supplier if the commission determines that the strategies are necessary in order for the conservation plan to be achieved:

   1. (A) conservation-oriented water rates and water rate structures such as uniform or increasing block rate schedules, and/or seasonal rates, but not flat rate or decreasing block rates;
   2. (B) a program to assist customers in the development of conservation pollution prevention and abatement plans;
   3. (C) a program for reuse and/or recycling of wastewater and/or greywater; and
