Wastewater Treatment Plant - Fact Sheet 02/04/2020


Indianola Wastewater Treatment Plant

Fact Sheet

February 4, 2020

  • Indianola has awarded a contract to Williams Brothers Construction in the amount of $45,600,000 for the construction of a new wastewater treatment plant. The innovative yet efficient new facility will replace the outdated plant and meet Iowa’s new, stricter environmental regulations for such facilities.
  • The new plant will be named the Indianola Water Resource Recovery Facility (WRRF).
  • The new wastewater treatment plant must meet the Iowa Nutrient Reduction Strategy as required for all large wastewater treatment plants in Iowa.
  • Indianola WRRF will be among the first wastewater treatment facilities in Iowa to meet the new nutrient removal requirements.
  • The plan is an innovative design that not only meets new requirements, but also treats peak flows in real time. The custom wastewater treatment solution selected reduces typical facility costs by $12 million.
  • With tourism events like the National Balloon Classic, Warren County Fair and Des Moines Metro Opera, Simpson College and others such as the Missouri Valley Technical Training facility drawing thousands of visitors to the community, a Local Option Sales Tax, passed in March 2016, will help fund this project.
  • Even with this significant investment, Indianola will remain more affordable than many other communities throughout the greater Des Moines metro area and the State (especially factoring in those facilities that will need to upgrade to meet the costly requirements for the Nutrient Reduction Strategy).
  • The process to design and construct a new wastewater treatment facility is a rigorous one with multiple regulatory requirements that need to be met. The contract award concludes six years of due diligence by the City of Indianola.
  • Completion of the project is expected in the summer of 2022.
