New water charges for Iowa customers

Beginning July 1, 2026, Iowa’s rate-regulated, investor-owned water and wastewater utilities can seek approval for new infrastructure charges. These fixed monthly charges depend on meter size and require Iowa Utilities Commission approval of a multiyear improvement plan. Eligible projects address legal requirements, resilience, health, safety, or environmental needs, including certain unreimbursed relocation and nonrevenue work. Recoverable costs include depreciation, property restoration, property taxes, and an approved return on investment—not violation penalties. Projects already included in the utility’s latest base rates are excluded. Annual charges can recover 80% of the eligible, unrecovered revenue requirement calculated before the charge application. The remaining 20% is deferred to the next general rate case. Combined water and wastewater charge revenue cannot exceed 10% of the utility’s latest approved revenue requirement—not each household’s bill. Costs above that cap are deferred to the next general rate case. When approved improvements move into new base rates, the separate charge resets to zero; those costs remain in base rates. Water and wastewater need separate plans and charges, and neither service can pay the other’s costs. Utilities can file one plan per service every 12 months. Plan approval and later cost adjustments require a final general rate order for that service within the past five years. Plans must document costs, engineering reviews, alternatives, schedules, and financial effects. The commission must decide plan filings within eight months, with extensions allowed for cause. Plan and charge filings must be published to inform customers.

Utility buyouts can affect customer rates

Beginning July 1, 2026, qualifying buyers of water, sanitary sewer, or storm water utilities can submit initial rates before closing. If the acquired system fails Iowa Code section 476.84(2)(a)’s requirements, the commission must consider acquisition expenses in the buyer’s next rate case. These include reasonable and customary closing, appraisal, legal, and regulatory costs. Consideration does not guarantee approval to recover those costs from customers. Customer rates can rise if the commission includes those costs in rates.
