Look for new bills this year for water usage. Though metering will not take effect until 2013 (when California requires the city to comply with the law), Folsom will begin showing you how much you will be paying next year. We will get a flat-rate as well as pay for water usage beginning 2013. If trends continue, this year looks to be a dry one – conserving water may soon be a necessity. Folsom Lake is at 40% and dropping.
