Drought Update

Drought Regulations remain in effect. In the face of the drought, City Council updated our Moderate Water Shortage Regulations in July 2021. City of Napa water customers must adhere to Water Waste Prohibitions in accordance with Napa Municipal Code Section 13.10 as we seek a 20% community-wide demand reduction.

NEW: Under State law effective June 10, 2022, watering of non-functional turf at commercial, industrial, and institutional sites is prohibited. Trees should continue to be irrigated appropriately. Violations of the turf irrigation ban can be reported online at savewater.ca.gov. Please visit the State Water Board's Water Conservation Emergency Regulations web page for more information.

Great job in 2022 City of Napa water customers.  We contained our irrigation last summer and it’s time to make sure those automatic sprinklers are off. With beneficial rains, our local surface water supply in Lake Hennessey is currently full. While we are thankful for that local recharge this winter season, our imported State Water Project supplies are currently allocating just 15% of our total water entitlements for 2023.  The current drought recovery will continue to be a multi-year process.  Keep it up Napa and thank you for using water, our precious resource, wisely!

In the drought of 2015 and 2016 our community reduced daily water usage by changing outside irrigation habits. We need to do it again.

Some easy steps to help reach our goal:

  • Limit lawn watering to two days per week to meet the regulations:
    • Even-numbered addresses may irrigate on Mondays and Thursdays only.
    • Odd-numbered addresses may irrigate on Tuesdays and Fridays only.
  • As always, avoid overspray and runoff. Sidewalks do not need to be watered.
  • Hand water dry areas rather than running sprinklers to excess.
  • Transition to one day per week watering in early fall, shut off irrigation for the rainy season.

Water Saving: How are we doing?

Water Consumption Trend

Small changes around the home can make a big difference. Save water now by:

  • Learning how to reset your controller. Remember to limit lawn watering to the prescribed days per week.
  • Applying mulch to planted areas to retain moisture in the soil.
  • Running only full loads of laundry or dishes.
  • When loading the dishwasher, skip rinsing and scrape food scraps into a compost bin instead of using the garbage disposal.
  • Turning off the water while you lather with soap, shave, or brush your teeth.
  • Not using the toilet as a trash can. Never flush wipes, tissues, masks, gloves, or paper towels.
  • Replacing an old inefficient toilet (>30 years old) with a new high-efficiency model.
  • Using a broom instead of a hose to clean off patios, decks, sidewalks, and driveways.
  • Finding and fixing leaks! Learn how to read your meter.
  • Getting an instant $100 rebate on the Flume 2 Smart Home Water Monitor!
  • Asking our Water Conservation Specialist for a free Water-Wise Home Survey.
