FORT WORTH (CBSDFW.COM) – Lawns across North Texas are already dry and yellow. Now, it could get even worse. The state’s extreme heat and drought have led to new watering restrictions for many cities in Tarrant County. The mandatory restrictions go into effect on Monday.

The Tarrant Regional Water District is implementing the Stage One restrictions just as the county’s storage capacity is expected to reach only 75 percent. The restrictions include residential and commercial customers in places like Fort Worth, Arlington and Mansfield, among many others.

For residents across Tarrant County, watering is only permitted twice a week, with exact days based on the address. Homes with addresses ending a odd numbers can only water on Sundays and Thursdays. Even addresses can water on Saturdays and Wednesdays.

Commercial customers – like businesses and parks – are permitted to water on Tuesdays and Fridays.

No watering is allowed, for anyone, between the hours of 10:00 a.m. and 6:00 p.m. on any day.

Also, the Tarrant Regional Water District is asking residents to make sure that they do not waste water by saturating sidewalks and parking lots. Plus, residents are encouraged to reduce the frequency of refilling swimming pools.

This is the first time that the Tarrant Regional Water District has implemented these tight water restrictions. They will be in place until conditions improve and North Texas sees a signifcant amount of rainfall.
