The Paso Robles City Council voted to lighten up on the city's water conservation rules during fall and winter.
Earlier this year, Paso Robles issued mandatory water conservation measures to customers because officials expected demand to exceed what the supply.
Hot weather, a state drought and stressed water supplies all played a part, officials said.
Paso Robles' roughly 10,000 water accounts -- representing about 29,950 people -- saved 20 percent of their typical summer usage from May to September compared to the same periods in 2008 and 2007, officials said.
Now, as hot days cool with fall and winter, the measures - such as limiting lawn watering to three days per week between 7 p.m. to 9 a.m. - will become voluntary Oct. 15 through April 1, 2010 and then return to mandatory when the heat picks up again.
