Daytime outdoor watering restrictions, enacted as part of Lewisville’s Emergency Water Management Plan, go into effect May 1 and will run through the end of September. Automated and manual sprinklers are not allowed between the hours of 10 a.m. and 6 p.m. during the summer months. Hand-watering and use of soaker hoses are not restricted.
The summertime restriction, which became mandatory in 2014 after being voluntary for many years, is intended to help conserve the city’s water supply by reducing water waste and evaporation that is common to daytime outdoor watering.
The city’s Emergency Water Management Plan is in effect year-round, limiting water customers to outdoor watering on two assigned days each week. Outdoor watering restrictions were made mandatory by the City Council in 2014 in response to the years-long statewide drought and its damaging impact on the North Texas water supply.
There are provisions for variances in certain circumstances, including properties with irrigation systems that do not tap into the city water supply, properties too large for all irrigation zones to be watered within the allowed time and properties that install new sod or landscaping.
Lewisville purchases water from Dallas Water Utilities and is required to adopt similar conservation provisions to those applied in Dallas. Similar restrictions have been adopted in Dallas, Fort Worth, Arlington and many other cities in the region.
Active water conservation efforts are a recommendation of the “Sustainability” Big Move in the Lewisville 2025 vision plan.
