Summary
Chula Vista enforces water conservation measures under CVMC Chapter 20.12 (Landscape Water Conservation) and applicable Sweetwater Authority or Otay Water District regulations. Landscape irrigation is subject to seasonal watering schedules and efficiency requirements.
About 40% of the water Californians use at home is used outdoors. Large water savings can be gained by efficient landscape design, installation, management, and maintenance. This is accomplished by choosing climate adapted plants, improving soil conditions, using, and maintaining high efficiency irrigation equipment and managing the irrigation schedule to fit the plants water needs as they are influenced by local climate. To increase water efficiency and better use a valuable resource, rainwater and stormwater collection and graywater and recycled water can replace or augment potable water use in landscapes. New development and retrofitted landscape water efficiency standards are governed by the Model Water Efficient Landscape Ordinance (MWELO) .

Full Breakdown
Chula Vista's Landscape Water Conservation ordinance (CVMC Chapter 20.12) implements the state Water Conservation in Landscaping Act requirements. New and renovated landscapes must comply with the Water Efficient Landscape Ordinance (WELO), including a maximum applied water allowance based on evapotranspiration rates. The city is served by two water agencies: Sweetwater Authority (western Chula Vista) and Otay Water District (eastern Chula Vista), each of which may impose additional conservation requirements and watering schedules. During drought conditions, mandatory water use restrictions may be enacted under the city's water shortage contingency plan. Standard restrictions include no watering during and within 48 hours of measurable rain, no excessive runoff, no using water to wash sidewalks or driveways (except for health and safety), and irrigation between 10 AM and 6 PM is discouraged. The conservation section can be reached at (619) 409-3893.
