Community Utilities of Indiana

Community Utilities of Indiana's (CUII's) service territories include:

  • Indiana Water Service, Inc. in Merrillville,
  • Twin Lakes Utilities, Inc. in Lakes of the Four Seasons, and
  • Water Service Company of Indiana, Inc. near Roselawn.
  • Pending Distribution System Improvement Charge (DSIC)

    CUII is seeking IURC approval of a Distribution System Improvement Charge (DSIC) in Cause No. 45998. The filing proposes adding a flat monthly charge of $1.47 to a residential customer's bill. On Feb. 5, 2024 the OUCC filed testimony (Compton, Parks, Willoughby) recommending limiting the increase to $0.61. The OUCC and CUII reached a settlement agreement that would limit the increase to $0.67 and the OUCC filed settlement testimony on Feb. 14, 2024.

    Indiana law (IC 8-1-31) allows water and sewer utilities to seek expedited rate recovery as often as once per year to replace infrastructure (such as aging distribution lines) that has exceeded its useful life.

    • The DSIC law allows a water or sewer utility to impose a surcharge to recover costs for replacing aging distribution or collection system infrastructure since its last rate case. Without this law, a utility would be required to wait until its next rate case to begin earning this return.
    • A surcharge may not be imposed for plant additions used to connect new customers.
    • Under the law, total surcharges cannot exceed 10 percent of the base revenue amount approved in the utility’s most recent general base rate case.
      • Certain costs can be recovered through the DSIC and not count toward the 10-percent cap. They include replacements of customer-owned lead service lines and galvanized steel service lines, costs for improvements placed in service due to road construction, and property taxes associated with eligible infrastructure improvements.
    • The surcharge requires IURC approval to take effect. A Commission order is required within 60 days of the utility’s filing.
    • By law, the OUCC must file its report within 30 days of the utility’s request. The OUCC’s review is statutorily limited to whether the infrastructure additions qualify under the statute and whether the surcharge has been calculated correctly.
  • 2021-2023 Rate Case (Current Rates)

    The IURC issued an order approving new rates for CUII on Feb. 1, 2023, in Cause No. 45651.

    The IURC also issued an order on reconsideration on May 3, 2023.

    CUII has appealed the rate case order, with the matter now pending before the Indiana Court of Appeals. Consumer parties, including the OUCC, have filed their brief asking the Court to uphold the Commission's order.

    UPDATE 1-18-24: The Indiana Court of Appeals issued an opinion on Jan. 16, 2024 upholding the Commission's order.

    The IURC dismissed CUII's 2020 request for a system integrity adjustment for its water utility. The adjustment would have added $1.63 to a monthly residential bill for 5,000 gallons.
