MINUTES OF CALLED MEETING OF THE BOARD OF WATER WORKS TRUSTEES PURSUANT TO NOTICE Tuesday, April 28, 2026 Present (or Participating by Video or Audio Conference Link): Board Members: Chairperson Mr. Alec Davis, Ms. Andrea Boulton, Mr. David Gross, Ms. Diane Munns, and Ms. Emily Kessinger (online) Staff members: Pat Bruner, Michelle Watson, Shirley Howard, Nathan Casey, Kyle Danley, Donna Heckman, Amy Kahler, Tami Madsen, Kelly Meiners, Nicole Nevarez, Jenny Puffer, Laura Sarcone, Melissa Walker, Lindsey Wanderscheid, Mike Zach, David Carroll, Doug Garnett, Ben Fitzgerald, Scott Ayres, Caitlyn Lloyd, and Rick Baldon Also in attendance: Amy Beattie, Suzanne Behnke, Bradley Johnson, and John Lande (Legal Counsel) Meeting Called to Order A motion was made by Ms. Munns, seconded by Mr. Gross, to resolve to approve Consent Agenda Items A through E, including the minutes from the March 24, 2026, Board of Water Works Trustees Meeting; the minutes from the April 7, 2026, Finance and Audit Committee Meeting; the minutes from the April 14, 2026, Planning Committee Meeting; the Financial Statements; the List of Payments for March, 2026; the Summary of CEO-Approved Expenditures in Excess of $50,000; and confirmation of May 26, 2026, as the next Board meeting date. Ms. Boulton was not present for this motion. It was noted that Ms. Kessinger’s name was missing from the minutes as a present member of the February Board Meeting. It was acknowledged by Ms. Kahler and will be corrected. Kelly Meiners provided financial highlights for the month ended March 31, 2026, noting that overall results from the Statement of Earnings were very strong. Water sales totaled $5.1 million, which is better than budget by $695,000. Operating expenses for March were $4.6 million, and this was better than budget by $432,000. The net change in earnings for March was a positive $656,000, and this is $932,000 better than budget. Year to date, we have experienced a positive change in net earnings of $486,000. Ms. Meiners discussed the net change in investment values for March of negative $765,000, which is called unrealized loss because none of the loss has been realized. We are required to value our investments at fair market value. We now have more than $70 million in investments because of our capital project funds, and those funds are invested in US Government securities. These have longer maturity because we're looking to use those project funds over several years. Their volatility changes with the interest rates so we will see a little movement month to month, but that is unrealized as we hold our bonds to maturity. Upon vote, the motion for resolution to approve Consent Agenda Items A through E was adopted with each member of the Board identified above as present (minus Ms. Boulton) voting in favor of the motion. Ms. Boulton was not in attendance for the motion to start the meeting or to approve the Consent Items.

Board Committee Reports The following reports were provided: • Finance and Audit Committee: The Finance and Audit Committee met on April 7, 2026. Discussion involved customer collection process, procedures, and information. • Planning Committee: The Planning Committee met on April 14, 2026. Tami Madsen, CIWW Executive Director, talked about the CIWW Water Use Plan with comments by Kyle Danley. • CIWW Board Highlights: •  Adoption of the Water Use Plan – with discussion of the 28E Agreement and waiver for Grimes. •  Authorization of the Technical Committee to initiate Phase 1 and Phase 2 (voluntary reductions) on an as-needed basis. •  Entered into an agreement with Aqualytics, a firm out of Omaha, to put together a smart irrigation project. • Des Moines Water Works Park Foundation Board: The Des Moines Water Works Park Foundation Board did not have a formal meeting in April 2026 but instead used the time for a strategic planning session. CEO and General Manager’s Comments Ms. Kahler welcomed Amy Beattie from the Stowe Foundation. Details are being worked out between the Stowe Foundation and the Park Foundation regarding coordination of work and permit requirements. Ms. Kahler shared that Quarter 1 Metrics were included in the packet due to the completion of the previous strategic plan time span and the current request for proposals for the new plan. There is a goal for DMWW to do more performance measurements and performance management. Ms. Kahler shared regarding her opportunity to go to Washington, D.C., for the Association of Municipal Water Agencies (AMWA) policy conference and DC fly-in and met with Congressional delegation staff and Congressman Nunn. Congressman Nunn recommended our lead service line project for congressionally directed spending. We have applied for $2.5 million to his office and team, which he supports and will forward to the House Committee for approval. Ms. Kahler shared a legislative update that DMWW is continuing its efforts for water quality monitors. We had requested an appropriation of $500,000 in accordance with previous years, but the current appropriation is $300,000. We will continue to support and monitor this carefully. We will also monitor legislation regarding The Iowa Public Agency Investment Trust (IPAIT) as we would oppose any caps placed on these investments. Ms. Kahler provided an operational update, noting that water usage was 46 million gallons per day as opposed to 60.5 million gallons per day, noting this is primarily due to cooler and wetter weather. Nitrate concentrations are persistently above 10 milligrams per liter in both rivers and the infiltration gallery. Current levels are approximately 12 milligrams per liter, and we are running 5-6 out of 8 nitrate removal vessels, which is nearing capacity as one is always off-line in maintenance mode. As the McMullen plant does not have nitrate removal, we rely on blending water sources or using the backup water supply, Maffitt Reservoir. We are both filling and withdrawing from Crystal Lake currently. Estimates show we have used 40% capacity from our backup supply at Maffitt Reservoir. Injections have resumed at ASRs to take advantage of this time of lower demand. We remain at Stage 0 for water use and are communicating that customers should follow water use best practices and delay lawn watering. Ms. Kahler offered congratulations to our new union leadership due to recent elections: Chair Justin Aalbers, Vice Chair Taylor Gruis, Secretary Luke Johnson and Treasurer Tonia Smith. Bill Blubaugh and Lori Leo were also recognized for their many years of service. Ms. Kahler recognized Mr. Gross for receiving the Business Record “Forty under 40” honor. Utility Updates • Safety Update: There have been three injuries and four vehicle accidents to date. There was also information about the reset of the Safety Committee, with more information to come. • Public Affairs Update: The Board received an April 2026 public affairs update highlighting recent activities. • Contract Status and Professional Services Agreements: Active construction and professional services contract summary was attached to the Board packet.
