Wastewater Treatment Plant Updates

The city's current wastewater treatment plant was constructed in 1978 and designed for a population of 11,600 residents.  With the current facility beyond its useful life of 30 years, aging infrastructure and stricter regulations, replacement of the current plant is necessary.  
This page has been created to provide updates, progress reports, and other information to aid in answering questions regarding the new wastewater treatment plant project.

Commitment



The City will be using 100% of the funds raised by the new Local Option Sales Tax for the wastewater treatment plant project.  Funding from the tax will not be used in courthouse renovations, road repair, or any other project that does not further the construction of a new wastewater treatment plant.  To view a letter from the City Council documenting this commitment, please click here.

With the construction of the new plant scheduled to begin early next spring will come a new name change. The name will change from Water Pollution Control to Water Resource Recovery Facility to reflect a changing paradigm in the water sector, focusing on resource recovery. Part of the treatment process will reduce the nitrogen and phosphorus that gets discharged to the receiving stream. With the DNR approval of Antidegradation Analysis and Facility Plan, the city received approval of the Construction Permit from DNR on December 13, 2019. This was the final step from DNR the city needed to start the construction of the new plant. To view a copy of the approved Construction Permit click here.

Progress Towards the  Future - HR Green met with the City of Indianola and held an informational meeting about a new Wastewater Treatment Facility.

During its study session, the City Council reviewed a financial model for the new wastewater treatment plant. The model is a long-term budgetary tool that allows the council to monitor the financial impacts as the city progresses with this much needed facility. As promised by the City, the financial model dedicates 100% of the local option sales tax towards this project. According to these projections, which will be reviewed on a regular basis, it is likely wastewater rates will remain at their current levels for some time. Click here to see the presentation that was reviewed.

May 2, 2016


The City Council approved the Facility Plan for the new Wastewater Treatment Plant.  The Facility Plan is a document that presents the City's anticipated treatment technology and systems.  This document was submitted for review by the DNR following the City Council approval.  As part of this process, the City is required to provide a separate submittal called Antidegradation Analysis.  This analysis provides technical data on what would be released back into the environment once treated by the new wastewater treatment plant.  In the City's case, the technology that was selected in the Facility Plan is considered to be the most environmentally friendly solution of the options considered by the City.  The regulations for the antidegradation analysis requires that there be a 30 day comment period on the analysis.  As such, the City will be hosting an open house on August 24, 2016 from 5:30 - 6:30 during which our Engineer on this project will provide additional information. To view a copy of the complete Facility Plan click here.

March 28, 2016


The City Council reviewed a draft of the facility plan for a new wastewater treatment plant. The facility plan is an important document that, once approved, will be submitted to the Department of Natural Resources to begin the permitting process.  The draft of the facility plan will be presented for formal consideration at an upcoming council meeting.
