Lewisville does not split watering days by a railroad or a creek. The published two-day pattern uses the street number. Even addresses, ending in 0, 2, 4, 6, or 8, and lots with no street number, are Tuesday and Saturday. Odd addresses, ending in 1, 3, 5, 7, or 9, are Wednesday and Sunday. Commercial, multifamily, and HOA properties are Monday and Thursday.
On the controller those are watering days, not start times stacked through the afternoon. From May 1 through September 30 the city also bars automatic irrigation and hose-end sprinklers from 10 a.m. to 6 p.m. A program that is legal in April can water at noon in June and draw a complaint. Hand watering and a soaker hose you place yourself are outside that daytime ban. A drip zone wired to the clock is not. It is automatic, and it takes the same days and the same hours as the spray zones.
The city posts the stage that is in effect on its outdoor watering page. Read that page before you leave a summer program running. This note describes the published day split. It does not declare that Lewisville is locked on one stage this week. Enforcement, including the city’s own complaint line and the OurLewisvilleTX app, is the city’s. It is not the repair desk.
Flower Mound, Highland Village, The Colony, and Coppell publish different days. A clock copied from a Lewisville neighbor is wrong across the city line. If you want the program set on site, the page is controller repair and the number is (940) 239-0007.
