FILTER PLANT AT NORFOLK.
The retiring board of water commissioners at Norfolk, Va, having had granted an appropriation of $250,000 for the purpose of acquiring an additional water supply and erecting a filtration plant—the basis of estimate of costbeitig$200,000 for the Little creek extension and $50,000 for natural sand filter beds, capacity to be 5,000,000 gallons per day, the new board, immediately upon coming into office, began an investigation of the two systems of filtration, namely, natural sand filter beds and mechanical filtration Finding estimates in the department as made by the retiring administration showing that $10,000 per million would provide for the cost of construction of the open sand filter beds, before going into the construction, it was thought best to have detailed plans made, showing the cost of such plant, and upon satisfactory reference, Mr. J. W. Ledoux, chie engineer of the American pipe works, was employed by the department to submit detailed plans and the cost. On October 19, 1898, he submitted a very elaborate set of plans, showing tie cost to be $150,000, and, as this amount was far in excess of the appropriation, the water board at once began an investigation of the various mechanical systems, and then asked for bids for a plant capable of filtering 6,000,000 gallons in twenty-four hours, witli floor space in building for an additional 2,000,000 gallons, when there came a demand for more than 6,000,000 gallons a day. Upon receiving the bids and considering the same, it was shown, as stated by the exhaustive report submitted by Mr. W. A. S Taylor, that the system now in the use by tlie New York Filter company, would more effectually meet the requirements of the department, and, after due consideration and a further reference to a epecial committee, the contract was awarded to that company on the 29th day of November, 1898, for tlie instalment of its system—covering improvements over the plans inspected, at the price of $55,000, and the contract for the building to Mr. E. Tatterson, at $23,000.
