Water Conservation Rebate Tax Parity Act

This bill amends the Internal Revenue Code to allow an exclusion from gross income of the value of any water conservation and efficiency measure or water runoff management improvement (or any subsidy, rebate, or other amount for such a measure or improvement) received from a water department. A "water department" means any entity (including a public or private utility, the federal government, or a state or local government) engaged in the provision of water to the public through pipes or other conveyances or in the collection, treatment, management, or disposal of storm water or waste water generated by the public.
