The San Francisco Public Utilities Commission is asking customers to voluntarily reduce their water usage by 10% because of ongoing drought conditions in the region.
The SFPUC provides water service to 2.6 million people in Alameda, San Francisco, San Mateo and Santa Clara counties. The announcement follows Gov. Jerry Brown's proclamation of a drought state of emergency early last week.
Brown called on all Californians to cut their water usage by 20% because of significant drops in water levels at local reservoirs and in mountain snowpacks.
SFPUC spokesman Tyrone Jue said the agency is asking for a 10% reduction instead of 20% because customers are already "very conscious about their water use."
San Francisco's water use is about 88 gallons per capita per day -- less than half of the statewide average of 197, according to the SFPUC.
The agency plans to make a formal announcement about the 10% percent voluntary reduction request on Friday.
The SFPUC encourages residents to take shorter showers, noting that each minute of shower time equals about 2.5 gallons of water. Clothes and dishwashers should also be used with full loads only, according to the agency.
