Unlike Plano and Frisco, Flower Mound and Lewisville’s water supply does not come from the almost dried-up Lake Lavon. Both cities purchase water from the Upper Trinity Regional Water District, Lewisville Lake and the Dallas Water Utitilities.

Although Flower Mound purchases 41 million gallons of water a day, only 29 million gallons are typically used, the city is already a month into its water conservation program. The restrictions started May 1 and remain effective until Oct. 1. The town implements the restrictions every year at the same time each year regardless of a water crisis.

The restrictions, although less stringent than other North Texas communities, prohibits residents and businesses from watering their lawn between 10 a.m. and 6 p.m. The town-enforced restrictions also state residents are not allowed to wash their cars during those hours. Certain businesses, such as golf courses, and city property are exempt from the restrictions.

The code enforcement department, the group that will enforce the water violations, can fine an offender up to $500. The group responds to complaints from residents and surveys the town.

“We’ll make every attempt to correct the issue before issuing a citation,” said Flower Mound communications specialist Juan Parra.

The town also has a program to reward citizens who use less than a certain amount of water per day. The plan lowers the amount of money a customer pays per gallon. The average customer uses about 13,000 gallons of water per day.

Lewisville has not implemented any water conservation program at this time. The city is asking residents to practice “responsible water use” by only watering their lawns on garbage collection days.

“Trash out, water on,” said Lewisville’s Public Services Director Carole Bassinger.

Lewisville has a three-stage plan for conserving city water, which is obtained from Lewisville Lake and purchased from the city of Dallas. The stages fall in line with state-wide water conservation and emergency management guidelines. Lewisville officials are recommending citizens to control water use during peak hours.

“We are closely and continuously watching water usage,” Bassinger said. “At this point, it’s sufficient for now.”
