The City of Grimes Water Utility operates and maintains three shallow alluvial wells, two Jordan Aquifer deep wells, an ASR well, two water treatment plants, a 1.5 million gallon above ground water storage tank, a booster station and a water distribution system consisting of underground piping, valves, and fire hydrants to accommodate the water needs of the residents of Grimes. On average, the City of Grimes uses anywhere from 2.2 to 3 million gallons of water per day depending on the time of year and weather conditions.

Water Treatment Plants

The City of Grimes has two drinking water treatment facilities.  These two plants produce water that is blended in an in-ground storage reservoir and then stored for use in the water distribution system to supply water to the Grimes community. 

Lime Softening Plant 

The lime softening plant was built in 2001.  This facility utilizes lime to disinfect and soften the water.  The water is then filtered and chemically disinfected.  The Lime Softening Plant can produce up to 1.7 million gallons a day.  

Reverse Osmosis Plant 

The reverse osmosis plant came online in 2021.   This plant utilizes pre-filters and pressure membranes in 4 reverse osmosis trains.  After the water leaves the Reverse Osmosis trains, it gets disinfected.    The Reverse Osmosis plant can produce up to 3.57 million gallons a day.  

Water Softeners

Grimes water is already considered soft. Adding a water softener to your home may overly increase the softness of your water.
