Tulsa water customers used 198.09 million gallons of water Sunday, the highest single-day use so far this summer.
If water use today surpasses 197 million gallons, the mayor will, through an executive order, implement voluntary water use restrictions.
A city ordinance says that if water use tops 197 million gallons per day (mgd) for two consecutive days, Stage 1 voluntary water restrictions will be asked. That means customers are asked to limit outside watering to the hours between midnight and noon every other day, based on odd-even address numbers.
If water use tops 204 mgd for two consecutive days, Stage 2 mandatory restrictions will be imposed. Stage two would make those voluntary restrictions mandatory.
If water use tops reaches 210 mgd for two days, watering would be restricted to the hours between midnight and noon every other day and with the use of a hand-held hose only.
If use grows higher, then outside watering could be prohibited.
The trigger levels for restrictions are based on the capacity of Tulsa’s two water treatment plants to deliver water to customers.
