G.P.M. Associates Inc. ("GAI") assisted Aqua Illinois, Inc. in a rate increase proceeding for 9 of its 10 water divisions and all 6 of its sewer divisions. In addition to receiving a rate increase from the Illinoix Commerce Commission ("ICC"), approval was granted to reduce the number of tariff groups for these divisions from 15 to 6 as Aqua Illinois moves toward single state wide rates for its water and sewer divisions.
GAI provided cost of service and tariff design studies for each division and the consolidated groups. GAI provided expert testimony and worked with Aqua Illinois in getting the final Compliance Tariffs approved by the ICC.
