Water And Wastewater Rates [Abstract]
Water And Wastewater Rates	Note 10 Water and Wastewater Rates During the first six months of 2012, the Company's operating divisions in Texas, Ohio, Illinois, Florida, New Jersey, Pennsylvania (wastewater), and Indiana were granted base rate increases designed to increase total operating revenues on an annual basis by $20,451. On June 7, 2012 the Pennsylvania Public Utility Commission granted the Company's operating subsidiary in Pennsylvania a water rate increase designed to increase total operating revenues by $16,700, on an annualized basis. The rates in effect at the time of the filing included $27,449 in Distribution System Improvement Charges ("DSIC") or 7.5% above prior base rates. Consequently, the total base rates increased by $44,149 since the last base rate increase and the DSIC was reset to zero. In addition, the rate case settlement provides for a flow-through provision allowing the book recognition of certain income tax benefits in the event the Company adopts a change to its tax accounting method related to expensing costs for utility assets that are presently being capitalized and depreciated for book and tax purposes. The Company is presently evaluating this adoption for its operating subsidiary in Pennsylvania for application in 2012 or 2013. During the first six months of 2012, the Company's operating division in Pennsylvania received infrastructure rehabilitation surcharges of $2,764. Infrastructure rehabilitation surcharges are capped as a percentage of base rates, generally at 5% to 9% of base rates, and are reset to zero when new base rates that reflect the costs of those additions become effective or when a utility's earnings exceed a regulatory benchmark. The Company's other subsidiaries received infrastructure rehabilitation surcharges of $1,390 during the first six months of 2012. In June 2012, the New Jersey Board of Public Utilities approved a rulemaking to implement an infrastructure rehabilitation surcharge for regulated water utilities; as a result, the Company's operating subsidiary in New Jersey is in the process of implementing an infrastructure rehabilitation surcharge. In October 2010, one of the Company's operating divisions in Texas began to bill interim rates in accordance with authorization from the Texas Commission on Environmental Quality ("TCEQ"). The additional revenue billed and collected prior to the TCEQ'S final ruling is subject to refund based on the outcome of the rate case. The rate case concluded with the issuance of an order on May 20, 2012, and no refunds of revenue previously billed and collected were required.
