The authority recommends watering plants three days a week, one time a day for 12 minutes at a time during those months.
Recommendations are for high-flow sprinkler heads.
Starting today, homes and businesses are barred from watering lawns and plants between noon and 7 p.m. in Las Vegas, Henderson and unincorporated Clark County, and between 11 a.m. and 7 p.m. in North Las Vegas. The watering restrictions are key elements of a Southern Nevada Water Authority plan to save billions of gallons of water a year by 2010. The authority missed its annual conservation goals in 1999 and 2000, which prompted grave predictions Monday and an advertising campaign, also starting today, that promotes water conservation as a social responsibility. The Las Vegas metropolitan area is the driest large city in the nation. But it has some of the cheapest water and one of the highest rates of per capita water consumption.
