Iowa Governor Kim Reynolds has unveiled a comprehensive water quality funding package that will channel $319 million into water infrastructure and monitoring across the state over the next 12 years.
Announced on 1 May 2026, the proposal was added as an amendment to House File 2771, the state's agriculture and natural resources appropriations budget. The Iowa House passed the bill 65 to 2, with unanimous approval of the water quality amendment.
The package restructures existing funding streams while introducing new programmes. It would eliminate the current Water Quality Financing Programme and redirect those resources, among other changes, to boost the Wastewater and Drinking Water Treatment Financial Assistance programme from $7.7 million to $12.09 million annually, alongside an $8 million one-time injection. The programme funds projects aimed at tackling both point and nonpoint sources of water pollution, with priority given to collaborative initiatives. Maximum grants to communities for infrastructure projects would also double, rising from $500,000 to $1 million.
A newly created Greater Des Moines Watershed Programme would receive $3.72 million per year to support upstream conservation measures such as cover cropping and edge-of-field buffers. The Iowa Department of Natural Resources would also gain $500,000 annually for expanded water quality monitoring.
Among the one-time investments is $25 million directed to Central Iowa Water Works to double its nitrate removal capacity within three years. The funding comes after nitrate levels in the Des Moines and Raccoon rivers reached particularly elevated levels in 2025, prompting a lawn watering ban the following summer. A new Rural Iowa Infrastructure Bank, capitalised at $10 million, would offer loans at 1% or below to small and medium-sized communities upgrading water and wastewater systems.
"Clean water is non-negotiable, and we stand here today to acknowledge that there is more work that needs to be done to modernise Iowa's water treatment infrastructure, in our fields, in our communities and in our utilities," said Agriculture Secretary Mike Naig.
Democratic lawmakers questioned whether the scale of the investment was sufficient, arguing that addressing pollution at source rather than at the treatment stage would be a more sustainable long-term approach.
