The report of Water and Sewer Bond Sales in the United States contains data which are basic and necessary to the orderly and efficient management of water supply and pollution control programs. The tables supplement the annual publication of contract award data, last reported in Sewage and Water Works Construction 1963. (PHS Publication No. 758.) Similar tables which describe bonds sold between July 1956 and December 1962 are available. The basic information from which these tables were developed was obtained from the Investment Bankers Association by special arrangement. Data are presented in three categories according to the use of the proceeds from the sale: (1) WATER when the bonds have been sold to finance water facilities; (2) SEWER, to finance sewage facilities; and (3) COMBINATION, to finance jointly water and sewage facilities where the portions attributable to each type are not designated. These data describe only those sales reported to the Investment Bankers Association or assembled by that Association from available documents.
