California and Napa County are in the midst of a historic drought. Businesses and residents alike are asked to work together to save water. Below we have gathered resources to help everyone conserve water and created messaging tools for our business community.

As of 2021, all 58 counties in California are under a drought emergency proclamation. At the  May 4, 2021, Town Council meeting, Town Council adopted Resolution 21-4054 approving the implementation of modified Phase 2 Water Emergency Regulations in response to the drought and the initial notice from CalVET of only 400 Acre-Feet from Rector Reservoir and Treatment Plant.

In an effort to combat the effects of the prolonged drought the Town of Yountville has implemented several water restrictions. The top of these effecting businesses include:

  • Outdoor irrigation with potable water delivered by the Town of Yountville Distribution system only allowed 6:00 p.m. and 10:00 a.m. to reduce evaporation loss with an odd/even watering schedule (off addresses water Tuesday and Friday; even addresses water Monday and Thursday)
  • No outdoor irrigation Wednesday, Saturday or Sunday with potable water delivered from the Town’s water distribution system
  • Irrigation is not permitted during or 48 hours after measurable rainfall
  • Hotels and Inns must clearly and prominently display notice of option to reuse towels and linens changes only upon guest request
  • Using water to wash any driveway or sidewalk
  • Using water in a fountain or other decorative water feature, unless the water is recirculated
  • Tap water can only be provided to customers upon request
  • Scrape all dishes prior to rinsing

Town of Yountville Water Resource Page


Water is a precious and limited resource, especially in drought-prone Napa County. As a result, water conservation and the efficient use of Napa County’s water supply are major priorities for the County.

We encourage all residents in Napa County to embrace wise water use as a daily habit, whether we are experiencing a year of heavy or meager rain. Start by clicking on one of the links below, which provides water conservation resources, rebates, tips and information regarding your local water agency, including water use restrictions. You can also visit Save Our Water for additional resources and ideas on how to conserve water.

Do we have enough water stored?

In drier seasons, we rely on other sources of water. These include reservoirs and melted snowpack. But we are now facing a historic level of dryness that has gone on for 3 years. And it’s only getting worse: 2022 had the driest January, February, and March in over 100 years.

Preparing for a new, drier normal

Weather extremes brought on by climate change have reduced our water supply. We are in a third year of drought and need to use less water.

When the wells of rural communities go dry or get contaminated, the state has water delivered to them. Here is Jose Aguilar of Self Help Enterprises bringing water to a community in the Central Valley. The State Water Board funds this project, providing water Californians need to survive in areas most stricken by drought.

What the state is doing

Here’s how California government is taking action:

  • Giving agencies the tools they need to tackle the drought emergency
  • Addressing long-standing water challenges
  • Securing vital and limited water supplies to sustain our state into the future

How you can help

Use less water

It is critical that Californians work together to save our water. That’s why we developed the Save Our Water campaign. More clean water makes the world a better place for our children and future generations.

State actions against drought

Governor Gavin Newsom called on local water suppliers to move to Level 2 of their contingency plans. This would help conserve water across all sectors. He also asked that a ban be considered on watering decorative lawns at businesses and institutions.
The State Water Board adopted new regulations to prohibit water waste in response to the ongoing drought emergency. They went into effect January 18, 2022.
Governor Gavin Newsom extended the drought emergency statewide. He further urged Californians to step up their water conservation efforts as the western U.S. faces a potential third year of drought.

Saving Water (Indoors)

  • Take 5 minute showers.
  • Purchase a low flow shower head.
  • Turn off the faucet while brushing your teeth or shaving.
  • Fix all leaky faucets.
  • Check your toilet for leaks. Put a few drops of food coloring into the tank and wait 30 minutes. If the food coloring seeps into the bowl, you have a leak.
  • Wash only full loads in the washing machine.
  • Wash only full loads in the dishwasher.
  • Capture tap water. While you wait for water to get hot in the shower or sink, catch the flow in a bucket or bowl and use this water for your house plants or garden.
  • Avoid taking baths. If you must fill your bathtub, try to fill it only halfway. A full bathtub uses 36 gallons of water.
  • Replace fixtures. Old fixtures tend to be inefficient. There is a good chance you can save water by replacing old fixtures.

Saving Water (Outdoors)

  • If rain is in the forecast, turn off sprinklers two days before the rain and keep them turned off for at least 48 hours after rain has stopped.
  • Check your irrigation system. Repair leaks, replace damaged sprinkler heads, and adjust sprinklers to avoid over-spray.
  • Do not hose down driveways, patios, stairs, or walkways. Use a broom or blower instead.
  • Don’t leave the hose running while washing your car. Use a nozzle with an automatic shut off and a sponge and pail of soapy water.
  • Put a layer of mulch around trees and plants. Two inches of mulch will help hold the moisture in the ground and cool the root systems. Leave a six inch space between mulch and plant.
  • Set your lawn mower blades higher. Set a blade heights at 2 or 3 inches. Longer grass blades will reduce evaporation and shade the roots.
  • Step on your grass and see if it springs back when you lift your foot. If the grass springs back, no need to water today.
  • Use a pool cover for your swimming pool. This can reduce evaporation.
  • Install a drip irrigation system. A low-volume water irrigation system uses less water.
  • In the winter, water your landscape only one day a week.
  • Retrofit your garden with drought-resistant plants or permeable landscapes. A great way to save money retrofitting your garden is with the Town’s Cash for Grass program. View the attached information to find out more.
