  • West Des Moines Water Works Board of Trustees Meeting Communication
    WEST DES MOINES WATER WORKS BOARD OF TRUSTEES MEETING COMMUNICATION DATE: May 20, 2020 ITEM: 5. Recommendations from Committees a. Planning and Regionalization 1. Motion – Approving the Funding Proposal with the City of West Des Moines for the Meridian Development FINANCIAL IMPACT: Total estimated project cost is $1.4 million. The agreement requires the developer to pay the South Area Water Connection Fee District Fee in the amount of $221,218.66 prior to the West Des Moines Water Works commencing any engineering. The agreement proposes the Water Works pay the initial $250,000 towards the project costs and the City will upfront the remaining amount. The Water Works will be committing to paying the remaining principal only over the course of 10 years to the City of West Des Moines. This project is a fee district main but was not planned for within our current 5-year Capital Improvements Plan (CIP). SUMMARY: On February 5, 2020, Hubbell Development Services along with the owner of the property and their engineer requested consideration for moving the water main extension up in our CIP to help with marketing of the distribution center. The planning and regionalization committee at the time concurred with staff’s recommendation that we not pursue amending our CIP and continue to direct funds on identified projects. This was relayed to the developer in a written letter. Since that time, the developer has continued to ask for other alternatives for getting water infrastructure to the site. Another letter was sent to the Board of Trustees and the City Council on May 5th asking how to move the project forward.

  • Agricultural Drainage and the Des Moines Water Works Lawsuit
    REPRINTED AND DISTRIBUTED WITH PERMISSION OF THE DRAKE JOURNAL OF AGRICULTURAL LAW 2017] Agricultural Drainage and the DMWW Lawsuit 109 AGRICULTURAL DRAINAGE AND THE DES MOINES WATER WORKS LAWSUIT Nathan Vos† PREFACE Two important cases have been decided since this Note was completed. First, on January 21, 2017, the Iowa Supreme Court answered the United States Northern District of Iowa’s Certified Questions in Board of Water Works Trustees of City of Des Moines v. Sac County Board of Supervisors.1 As expected, the Iowa Supreme Court held the Drainage Districts of the Iowa counties, Sac, Calhoun, and Buena Vista, were not proper parties to sue under Iowa statute or common law and, therefore, could not be sued for any kind of damages under state law.2 Second, and surprisingly, on March 17, 2017, the District Court3 dismissed the Des Moines Water Works lawsuit in its entirety—both on the state claims and the federal Clean Water Act claims.4 Des Moines Water Works is not expected to appeal this decision. Importantly, none of the water municipal’s federal claims were addressed substantively when the case was dismissed.5 Instead, the federal District Court dismissed the claim on procedural standing technicalities6 due to the limited governing nature of drainage districts.7 Readers interested in this litigation and development of similar environmental litigation, will find this Note helpful as it † J.D., Drake University Law School, May 2017, B.A., Political Science, Iowa State University, December 2013. 1.

Natural resources and landscapes are a result of geological processes that occurred over millions of years. The past of Calhoun County displays some of the county’s history in more recent years as humans have settled in the area. Calhoun County bedrock is similar to other state patterns, but also has a unique area from the Manson Impact Structure. The geology of the state has changed throughout the years and continues to change as a result of human interactions. Some of these interactions have affected the natural resources found within the county. Through the application of the project, students will learn about a unique geological feature and how it has and continues to affect their community. Introduction The Manson Impact Structure is a unique geological formation found in Iowa within Calhoun, Humboldt, and Pocahontas counties. The school district in which I teach and the homes of many of my students lie directly above the impact structure. Although some students are aware of the geological history of the Manson area this activity would provide the opportunity for students to gain a deeper understanding of the previous geologic activity of the area.

  • Aquifer Storage and Recovery Case Study Site: Des Moines and Ankeny, Iowa
    Aquifer Storage and Recovery Case Study Site: Des Moines and Ankeny, Iowa Highlights “DMWW became acutely aware of how reliant it was on a single treatment plant when it was unable to provide water to customers for 11 days during the flood of 1993.” -As stated in Miller and Beaver (1997) ● The Des Moines Water Works (DMWW) is a regional municipal water utility that supplies water to 500,000 people in central Iowa. ● The DMWW expanded its water production capabilities after the 1993 flood to avoid future production crises which included the establishment of five Aquifer Storage and Recovery (ASR) wells in collaboration with the City of Ankeny Water Utility. ● The five ASR wells maintained by the DMWW and the City of Ankeny Water Utility all exceed a depth of 2,500 ft and are some of the deepest ASR wells in the world. ● The recharge water sources for the ARS wells are treated potable water from the DMWW water treatment plants. ● The ASR wells are permitted under the EPA Underground Injection Control (UIC) Program and also must comply with permits required by the state including approval of engineering drawings and specifications, management of stored and recovered water, and a National Pollutant Discharge Elimination Standard (NPDES) permit. Summary The Des Moines Water Company was established as a private company in 1871 to provide a stable supply of water to the city of Des Moines, Iowa. The company continued to function privately with different owners and managers until 1919, when the city bought the water company, changed the name to Des Moines Water Works (DMWW) and converted it to a public utility owned by ratepayers.
