S&P Global Ratings maintains long-term revenue debt ratings on approximately 1,600 obligors for municipal water and wastewater utilities (as of Dec. 16, 2019). This includes multiple security types and issues, but with the same obligor (e.g. Chicago issues both water and wastewater revenue bonds that are separately secured by dedicated revenue streams). This list excludes debt issued by regional wholesale water and wastewater providers, as well as debt issued by state agencies to fund water and wastewater projects. For a comprehensive view on ratings distribution and national and regional median ratios for the sector, see "U.S. Municipal Water And Sewer Utility Sector Is Stable As Median Ratios Show Improved Finances" (published Aug. 23, 2019, on RatingsDirect).
