Public Utilities  -  Landscape Watering Calculator

The calculator has been designed to give you a weekly schedule for the maximum amount of water which your plants may need each month of the year. Because everyone's landscape is different, the calculator has been simplified by using average numbers for weather, plants, and soils in San Diego.

IMPORTANT: The Landscape Watering Calculator does not reflect local mandatory conservation measures that may be in effect because of the current water supply shortage. Please read the Mandatory Water Use Restrictions page (or check with your own water supplier if you live outside of the City) to learn your restrictions. For example, current outdoor watering restrictions in the City of San Diego are as follows:

• Residences with odd-numbered addresses Water ONLY on Sunday, Tuesdays & Thursdays
• Residences with even-numbered addressed water ONLY on Mondays, Wednesdays & Saturdays
• Apartments, Condos & Businesses water ONLY on Mondays, Wednesdays & Fridays

• November 1 - May 31: Water between 4 pm and 10 am; for only 7 minutes per station when using a standard sprinkler system.
• June 1 - October 31: Between 6 pm and 10 am; for only 10 minutes per watering station when using a standard sprinkler system.
