Today the system has 20 wells providing raw water to three treatment facilities. Continued growth required the expansion of the first plant in 1965 to 1.0 million gallons per day (MGD), construction of a second plant in 1971 with expansion to 3.0 MGD in 1975 and the purchase of a third 2.0 MGD plant in 1981. In April 2002 the Utility purchased 2,300 customers from Hamilton Western Utility.
In June 2006 the Utility purchased 8,300 residential customers and some commercial customers from Indianapolis.
Treatment in all plants includes iron removal, softening, disinfection and fluoridation.
With internal usage the system currently can produce approximately 36 MGD for distribution.
In 2012 opened a new water treatment plant at 106th & Gray Road.
