Our water source is purchased, pretreated water from the City of Tulsa, City of Sapulpa and Creek County Rural Water District #1. Water purchased from the City of Tulsa serves the northern part of our District, portions of the southeast part of our District, and some areas of the City of Kiefer.  The City of Tulsa relies on water from two sources.  Lake Oologah on the Verdigris River and Lakes Spavinaw and Eucha on Spavinaw Creek. Water from Lake Oologah is treated at the A.B. Jewell Treatment Plant; Water from Lakes Spavinaw and Eucha is treated at the Mohawk Treatment Plant.  Water purchased from the City of Sapulpa serves the rural Sapulpa area.  The City of Sapulpa relies on surface water from Skiatook Lake and Lake Sahoma.  Both sources of water are treated at the Sapulpa Treatment Plant. The water purchased from Creek County Rural Water District #1 serves the Southern part of our District, including some areas in the City of Kiefer.  Creek County Rural Water District #1 relies on surface water from Lake Heyburn; it is treated at the District #1 Treatment Plant.
