SB 606 and AB 1668 FAQs


On May 31, 2018 Gov. Jerry Brown signed into law two new bills that will require urban water providers throughout California to set new permanent water use targets for their service areas by 2022. Senate Bill 606 (Hertzberg) and Assembly Bill 1668 (Friedman) provide a framework for setting water use targets, as well as implementing and enforcing the new water use requirements. There are no immediate impacts to customers from these new laws.


While many details for implementing the new water use requirements will be determined over the next several years, the overall framework includes:

·         A standard for indoor residential water use of 55 gallons per person per day—dropping incrementally to 50 gallons beginning in 2030.

·         A standard for outdoor water use (to be determined) based upon and the amount of irrigable landscaped area for a residential or dedicated irrigation commercial account and the community’s climate.

·         A standard for water loss due to leaks in water system pipes (to be determined).


These three standards will be calculated and added together to represent an overall water use target (in gallons) for the water provider. Although some local water providers in California base their rates on a water budget for each customer, the new state laws do not contain water use targets applicable to individual residents or businesses.


These laws outline an overall framework to guide water providers in setting water use targets, which must be approved by the State Water Resource Control Board (State Water Board). However, each water provider will determine how it can best achieve the new water use target for its service area. Water providers will set and monitor targets for their service area as a whole (not on an individual customer basis) and will determine how to help their customers collectively reach the new targets. Water providers who do not meet their targets can be fined by the State Water Board (up to $1,000 per day during non-drought years and $10,000 per day during drought emergencies). Fines apply to the water provider and not to individuals.


The Regional Water Authority and Sacramento-area water providers were very active in helping to shape these new laws and will continue their work to define the details of its implementation. In California, droughts are a part of life, and the next dry year is always right around the corner. Local residents have consistently shown their willingness to do their part to use water efficiently during the drought and beyond. Water providers look forward to continuing their partnership with customers to implement these new laws and to make water efficiency a way of life.



Frequently Asked Questions


How will the new laws impact customers?

There are no immediate impacts to customers. Over the next several years, specific water use targets will be set for a water provider’s overall service area (not on an individual basis) based upon the standards outlined in the laws. Once water provider-level targets are established in 2022 and implementation begins in 2023, water providers may choose to work with individual households and businesses to increase their water efficiency through available rebates, services and programs.


Will it be illegal to take a shower and wash clothes in the same day, as some media have reported?

No. There is nothing in the laws that specifies when or how often a person may shower, do laundry, or use water for any other purpose. The new laws outline an overall framework for setting and meeting water use targets at the water provider level. While the framework outlined in the laws does include a goal for individual water use of 55 gallons per person per day beginning in 2022, this applies on an overall system-wide basis (and not an individual basis).


How hard will it be to meet the indoor target of 55 gallons per person per day?

It’s important to note that the target of 55 gallons per person per day is not a goal for individual water use, but will be measured across a water provider’s entire service area. That said, water industry experts are projecting that many people are already meeting this target or do not have far to go.


The Alliance for Water Efficiency has an online water calculator that can estimate how much water a household uses indoors. You can find it at In the Sacramento region, individuals currently use about 66 gallons of water per person per day inside their homes.


To help people reduce their indoor water use, many water providers offer rebates for upgrading fixtures to high-efficiency toilets and clothes washers. Be sure to look for the WaterSense and ENERGY STAR labels. You can learn more about rebates at


Will water providers be monitoring and evaluating individual water use as part of the new laws?

No. There is no requirement in the new laws that individual households must meet a specific target. The new laws provide a framework for setting targets, but those will be applied on a system-wide basis, and progress toward achieving targets will be reviewed on a system-wide basis. 


How will the new laws impact businesses in California?

While the new laws do not set specific water use targets for business, they do outline a framework for creating new water efficiency performance measures for businesses—these are recommended actions for specific business sectors to improve water efficiency over time. Performance measures will be determined over the next several years, and the process will include opportunities for public input.


Will individual residents and businesses be fined for not meeting water use targets?

The regulations and associated water use targets are required for the water provider as a whole (including all customers) NOT at the individual resident or business level. Therefore, individuals and businesses will not be fined by the state for not meeting the water provider water use target. However, individuals and businesses may be fined for violating current local water provider water waste ordinances and guidelines.
