Water Treatment History

More than six decades ago, the completion of the Pensacola Dam in Disney, OK created the Lake O’ the Cherokees, better known as “Grand Lake”. Before the completion of the mile-long, 15-story-tall dam that would impound the 1,672,000 acre feet body of water, an Intake structure was constructed at Honey Creek State Park on Grand Lake that provided water to the City’s Water Treatment Plant for over 60 years until 1994 when a new floating Raw Water Intake structure was built next to the “old intake structure” which made the old structure obsolete.

A new Water Treatment Plant and pumping station was built in 1991 with a design capacity of 2.2 mgd (million gallons per day) to serve the rapidly growing City of Grove and the surrounding area. Over the years, treatment capacity has increased to 4.4 mgd with eventual capacity to reach 6.6 mgd. During the expansions and upgrades, improvements were made to the chemical feed facilities. In addition, a “state of the art” computerized SCADA (Supervisory Control and Data Acquisition) system was installed. A comprehensive process control alarm system was updated in 2004.
