Odd/even system is mandatory effective immediately.
Oklahoma City officials have implemented a mandatory odd/even watering program effective immediately. The rotation program includes residents and businesses and will remain in effect until further notice. "Oklahoma City's water-supply lakes, Hefner, Overholser and Draper are just over half full," said Utilities Director Marsha Slaughter. "We don't know how long the drought will last, but it's important that residents consider water conservation when they plan their landscaping, choose plants and renovate their home." Cities that use Oklahoma City water are also required to comply with the outdoor watering restriction as a minimum. Those cities include Blanchard, Edmond, El Reno, Moore, Mustang, Newcastle, Norman, Piedmont, Yukon, Canadian County Rural Water District #3, the Deer Creek Rural Water Corporation, Tinker Air Force Base and Pottawatomie County Rural Water District #3.
