Grinnell is upgrading its treatment plant. Its city project page compares 22 grains with a future 7-grain estimate and now lists January 2027 operation in the project table. We size equipment for today’s tap reading and plan to adjust it when the supply changes.

The City of Grinnell’s improvement page compares a current 22-grain figure with a future 7-grain estimate. Its project table now expects the nanofiltration plant to operate in January 2027; other FAQ timing on the page differs. Treat the lower figure as a future estimate, not a present tap reading.
For a purchase or repair today, measure your home’s hardness. We can plan capacity and regeneration for current conditions, then recheck settings when the city confirms the new supply is in service. Related: note on what limescale does to appliances · signs you need a softener.
For a Grinnell installation, we check people in the home, bathrooms, simultaneous water use, measured hardness and available flow. Then we review pipe size, existing equipment, a suitable drain, electrical access, bypass position and space for tanks and salt access. Under-sink RO also needs cabinet room, a faucet position and a drain connection; tankless equipment needs power. This makes the written recommendation useful before installation day.
Grinnell publishes a municipal report and updates on its treatment project. If you have a specific concern, keep the relevant test date and sample location with the result so we can match treatment to the actual issue.
For a nitrate or other specific drinking-water concern in Grinnell, we start with a current certified lab result and plan treatment from it. For nitrate, that lab test covers nitrate and arsenic, and we choose the system from the results and test again after installation. The free home screening measures hardness, iron, total dissolved solids and a nitrate screening reading. Additional laboratory testing is chosen for the concern.
The recommendation identifies the treatment goal, the selected equipment’s documented performance and the follow-up check. Aesthetic carbon filtration and a general TDS reading do not establish reduction of a particular contaminant.

We confirm pretreatment needs, model operating limits, service access and any additional plumbing in the written scope. Related: well water system · free well water testing
If an existing softener in Grinnell stops using salt, leaks, runs constantly or leaves hard water, start with diagnosis. Share the brand, model, error code and an optional photo of the valve or plumbing. We assess bypass position, brine draw, controls and the condition of serviceable components, then explain repair versus replacement, parts availability and the cost before proceeding. After a Grinnell installation, keep salt above the water level as directed, watch for salt bridges and have the regeneration settings checked if water use changes. Carbon media and RO filters need replacement on the selected system’s schedule; RO membranes are checked for output and performance. Whole-home warranty terms include lifetime parts, five-year media and one-year labor coverage under the written terms. RO coverage is confirmed for the selected model.

Grinnell’s project page compares a current 22-grain figure with an estimated 7-grain result after its new plant starts. Verify your present tap reading; the future figure is a target. Softening targets hardness, carbon filtration addresses appropriate taste and odor, and RO adds a drinking-water outlet. We connect your tap results with household use and the result you want.
Size treatment for your current tap reading, then recheck hardness and regeneration when the city confirms the new plant is in service. The lower hardness estimate on the project page describes planned future water; it is not a measurement at your home today.
