Water is Life. Water covers two-thirds of the Planet Earth, and makes up nearly two-thirds of our bodies. And there is no new water! All the water on the planet is constantly being recycled. We must take care of this resource.
City employees work long hours to keep Tulsa's drinking water and storm water safe and clean. Employees staff our treatment plants 365 days per year, 24 hours per day. These trained professionals not only monitor the results of computerized tests but also conduct tests themselves every two hours.
Pipes bring raw water from our source lakes Eucha, Spavinaw, Oologah and Hudson. Professionals test this water before it enters our two drinking water plants. Those tests provide information that tells us the quantities of chemicals needed for treatment.
Sediment in our source water is a major problem. The turbidity (cloudiness) of the water is monitored throughout the treatment process. Employees even monitor finished water as it travels through the distribution system. The City of Tulsa works hard to ensure that the water that comes out of the faucet is safe for drinking, cooking, bathing and other purposes.
Tulsa has two water treatment plants, Mohawk and A.B. Jewell, that can treat 220 million gallons of water per day (MGD). Our water distribution system consists of 2,237 miles of underground water lines, thousands of valves, 145,933 water meters, 15,927 hydrants, 12 pump stations and 12 treated water storage reservoirs in the Tulsa city limits. (December 2009)
Average daily pumpage is 102 million gallons per day. In 2011, we set a new record for maximum pumpage, 209.03 million gallons on July 16 of that year.
Each year the City of Tulsa provides a Water Quality Report for those who are using water treated by our Treatment Plants. This report meets a federal reporting requirement. Residents can view reports for previous years through the following links.

Water is referred to as hard or soft because of the presence of minerals in the water. In eastern Oklahoma, much of the water used for public water supply comes from lakes (surface water). This water has flowed over the ground in streams or rivers until it reaches a lake where it is stored and eventually consumed. Another type of water - groundwater - flows through soil and permeable rock before it trickles out into a stream and eventually a lake. As water moves, it picks up minerals from the rocks and soil. Two of these minerals, calcium and magnesium, accumulate and create the "hardness" rating of your water. This rating is measured in Parts Per Million (ppm) or Grains Per Gallon (gpg). The more minerals present in the water, the "harder" it is.
Water hardness is not a safety issue. Water is safe to drink no matter what the hardness rating is.
|Grains Per Gallon (gpg)||Parts Per Million (ppm)||Rating|
|less than 1.0||less than 17.1||
|1.0 - 3.5||17.1 - 60||
|3.5 - 7.0||60 - 120||
|7.0 - 10.5||120-180||
|over 10.5||over 180||
