LINN COUNTY, Iowa — As conversations about future growth and potential data centers continue across Eastern Iowa, both Linn County and the City of Cedar Rapids are investing in projects designed to better understand and protect local water resources.
Linn County is launching a new groundwater monitoring program that will track water levels in wells throughout the county.
The initiative will utilize existing bedrock wells and 16 new shallow wells near the Cedar and Wapsipinicon rivers, creating a network that provides real time information about groundwater conditions. The goal is to gather better data that can help guide future decisions about water resources.
“We don’t want to just be reactive. We want to be able to make decisions that are based on solid data,” Cara Matteson, Sustainability Director for Linn County, said.
The monitoring system will feed information into a public dashboard, allowing residents, researchers and government agencies to track groundwater levels and observe long term trends.
“It’s ultimately going to be a decision making tool. It’ll also show us over time, over many years, it’ll show us trends of if water levels are staying the same, going up, going down,” Matteson said.
County leaders say the project was not created in response to any specific development proposal but could provide valuable information as the region continues to grow and water demands evolve.
Meanwhile, Cedar Rapids is moving forward with its Aquifer Storage and Recovery, or ASR, well project. The system will store treated drinking water approximately 1,500 feet underground in the Jordan Aquifer and allow the city to recover that water later during periods of higher demand or when river conditions are challenging.
Cedar Rapids Utilities Director, Roy Hesemann, says the project essentially creates an underground reserve of drinking water.
“It’s really just like a big storage reservoir underground. Only this one’s 1,500 feet underground, and it’ll be there for our disposal whenever we need that resource,” Hesemann said.
The project has been in development for about a year and is expected to take several years to fully complete as infrastructure is built and tested.
The project is part of a broader effort to prepare for future water needs rather than a response to proposed data centers.
“We just want to be proactive, make sure that we have adequate water for whoever. We don’t care if it’s a data center, an extension of one of our existing industries that’s already here, or someone totally different that’s knocking on our doors and want to make Cedar Rapids their home,” Hesemann said.
Both projects are focused on long term planning and ensuring the region has the tools needed to maintain a reliable water supply for residents, businesses and future growth.
