The city of Lakeway, amongst other central Texas communities, requires a common sense schedule for irrigating. http://www.lakewaymud.org/irrigation_schedule.php
For water delivery in Austin and surrounding areas, remember to water before 10 a.m. or after 7 p.m. for maximum water retention and benefit. Lantana also offers irrigation services using rainwater. This can be done on any day despite city restrictions. However, Lantana attempts to water at the most beneficial times of the day.
