Water and Wastewater Rates	Note 9 Water and Wastewater Rates During the first nine months of 2011, the Company's operating divisions in North Carolina, Ohio, Indiana, Pennsylvania, and Maine, were granted base rate increases designed to increase total operating revenues on an annual basis by $6,087.
