The California Water Resources Control Board has eased the mandatory 25 percent statewide water conservation rules, allowing cities and local water agencies to set their own targets.
The state board has adopted a "stress test" approach to water conservation regulations.
The City of Roseville set its goal under the new system, but it is not mandatory.
Roseville has adopted a 10 percent voluntary reduction goal for its water customers from May though January 2017.
The city says even though water supplies have improved, water efficiency is necessary, as drought conditions continue in California.
Between May and August, Roseville water customers are encouraged to maintain a three-day-per-week lawn watering schedule. And outdoor watering is only allowed after 8 p.m. and before 10 a.m.
The statewide water efficiency rules still prohibit washing down sidewalks with a hose, instead of a broom or brush, watering lawns within 48 hours of rain, and washing cars without a shut-off nozzle.
