DeKalb County, which touts itself as the greenest urban county in the nation, is reminding residents that some conservation products are tax-exempt this weekend.

WaterSense-labeled toilets, showerheads, faucets and other products use at least 20 percent less water than conventional models. Products of up to $1,500 carrying the label are exempt from state and local sales taxes in Georgia between Friday and Sunday.

A list of labeled projects is online at www.epa.gov/watersense.
