The City of Philadelphia has enacted the Twenty-Eighth Supplemental Ordinance to its Restated General Water and Wastewater Revenue Bond Ordinance of 1989. This ordinance authorizes the Bond Committee to issue and sell up to $1 billion in new money water and wastewater revenue bonds. The proceeds from these bonds will be used to finance the construction, acquisition, reconstruction, and renovation of wastewater treatment plants, water treatment plants, water, wastewater, and stormwater pipes, pumping stations, and related facilities and equipment for the sewer and water systems. It also covers stormwater management and mitigation improvements related to the Green City, Clean Waters Program and the purchase of capital equipment and vehicles. Additionally, the ordinance authorizes the issuance of refunding bonds to refinance existing debt. The bonds are secured by pledged Project Revenues and do not pledge the City's general credit or taxing power.
