Water customers are limited to two outdoor watering days per week on assigned days for lawn and landscape irrigation. In addition, during the hotter months from May to September, daytime watering by automatic irrigation or hose-end sprinklers between the hours of 10 a.m. to 6 p.m. will be prohibited in most cases. The restrictions will apply to all City water customers.  

Lewisville purchases water from Dallas Water Utilities, and is required to adopt conservation provisions that are consistent with those applied in Dallas. Similar restrictions already have been adopted in Dallas, Fort Worth, Arlington and many other cities in the region.

In the future, if needed, additional conservation measures could be added.  This could include once a week outdoor watering or a complete ban on outdoor watering.

So when can I water?

Residential Customers:
Year-round watering schedules for residential customers will be determined by their street address:

  • Even-numbered address (ending in 0, 2, 4, 6, or 8) or no street address are allowed to water only on Tuesday and Saturday.
  • Odd-numbered address (ending in 1, 3, 5, 7 or 9) are allowed to water only on Wednesday and Sunday.

Commercial Customers:
Commercial and multi-family customers will are allowed to water only on Monday and Thursday.

What else do I need to know?

Hand watering, drip irrigation and soaker hoses are allowed on any day at any time.

All customers are asked to avoid watering during the hottest hours of the day when seasonally high temperatures will cause evaporation of water being applied by sprinklers.

During the peak summer months of May 1 to September 30, landscape watering by automatic irrigation or hose-end sprinklers will not be allowed between 10 a.m. and 6 p.m.

There are provisions for variances in certain circumstances, including:

  • Properties with irrigation systems that do not tap into the City water supply. This includes properties with their own water well, and properties that have an approved detention system that recycles the irrigation water.

  • Properties that are too large for all irrigation zones to be watered within the allowed time. Those properties can request a variance allowing them to spread their watering into additional days, but with each zone only being watered the approved number of times per week.

  • Properties that install new sod or landscaping. A variance can be requested to allow more frequent watering for a set period of time to allow the new plantings to become established.
