Based on recommendations from the North Texas Municipal Water District, the Frisco City Council at its Tuesday regular meeting will consider going back to allowing once a week sprinkler system use through the end of October.

The NTMWD is making its recommendation to ensure water quality is maintained throughout the distribution systems, according to a press release.

"The Texas Commission on Environmental Quality requires that water providers maintain chlorine residuals in transmission and distribution systems to assure water quality so that the treated water supply is safe for use," NTMWD said in the release. "Annually, chlorine residuals are depleted by increases in temperature during summer months. During the summer of 2014, NTMWD consumers have reduced their water usage so well that maintaining chlorine residuals has been compounded by the decreased demands."

NTMWD member cities and customers flush water hydrants to remove water that has decreased chlorine residuals. Once a week water with sprinkler systems will help maintain the required chlorine residuals, improve the circulation and increase the water flow within the system, according to NTMWD officials.

Both summer rain and reduced water usage has allowed the NTMWD to go to once a week watering through the end of October and still keep Lavon Lake's elevation high enough to avoid Stage 4 water restrictions.

"While water quality remains the top priority, water conservation and the wise use of water is still critical to maintain our current available supplies until the drought eases," officials said in the release.
