Oct. 24, 1873 Commissioners of works and public buildings of Her Britain and Ireland Statement showing amount of tax for laying water-mains assessed against church property, and remaining unpaid on the water-tax books November 15, 1876. Exempt under acts of Congress approved June 17, 1870, and March 3, 1875. See supplement to annual statement of taxes for laying water-mains remaining unpaid under head of “ churches.” WATER-REGISTRAR'S OFFICE, DISTRICT OF COLUMBIA, November 15, 1876. WATER-SUPPLY. The engineer of the Washington Aqueduct, in his last annual report, estimates the quantity of Potomac water used in the District of Columbia every twenty-four hours at 25,000,000 gallons. Approximating the population of both cities, Washington and Georgetown, at 146,000, would give 165 gallons to each inhabitant thereof; 2,000,000 gallons a day (24 hours) more than in 1875; 8,000,000 more than in 1873; 13,000,000 more than in 1870, and 17,000,000 more than in 1864. This increase can in part be accounted for by the large number of water-takers, both in new and old houses, as also in the waste of water both in private and public buildings. The following table illustrates the number of water-takers from July 1st, 1859, to date: January 1, 1864, to January 1, 1865.. 444 162 359 85 January 1, 1865, to January 1, 1866. Total number of takers. In private buildings, during the past season, measures were taken to check the evil, and with success, so far as to give parts of the city on the higher elevation, heretofore without water, a fair supply. This subject, "waste-water," is fully discussed in another part of this report. As to public buildings owned and occupied by the General Government, this department has no control either to regulate the water-supply or to check the waste that is daily observed. The following table illustrates approximately the quantity of water used every twenty-four hours in nineteen public buildings: Treasury Amount of water used by Government buildings every twenty-four hours.
