Gwinnett County will expand its toilet rebate program to multi-family units in 2012.

The county offers rebates of up to $100 to homeowners to replace up to two original toilets in homes built before 1993 because the older toilets use more water. Gwinnett residents have replaced nearly 9,500 inefficient toilets through the program.

On Tuesday the county Board of Commissioners agreed to continue the rebate program in conjunction with the Metropolitan North Georgia Water Planning District. For more information on the program, visit www.northgeorgiawater.com.
