The City of Grimes was in need of water treatment improvements in order to meet the water demands of their growing community. The project includes the construction of a new 23,000 square feet Reverse Osmosis Water Treatment Plant, with a new administration area, four (4) RO treatment trains, chemical feed, and high service pumping. The new plant can produce 3.0 MGD of finished water upon completion, with room to expand capacity up to 6.0 MGD. The plant treats Jordan Aquifer water utilizing a direct RO treatment scheme, with finished water being blended with water from the existing lime softening plant.
