In April, 1903, by the election of Mayor Hays, the Bigelow faction again came into power and Mr. Bigelow was reappointed director of public works. Councils reorganized. A reform, or Bigelow man, was elected to the presidency of councils, control of committees was secured, and by the middle of 1903, the Bigelow faction was again in full power.
By this time the South Side was demanding filtered water. The new estimates presented by Director Bigelow in September, 1903, included ten filter beds for the South Side, and the raising of the pumping capacity for the first twenty-three wards by twenty million gallons, and included also, new machinery and boilers for the Brilliant pumping station, and a fifty-inch steel main across the city to supply the South Side and the Monongahela River wards of the old city. These brought the total new estimate up to over seven million dollars.
The time between September 21, 1903, and January 12, 1904, was required to get a resolution through councils and approved by the mayor, authorizing the finance committee to employ three experts, Col. Alexander M. Miller of Washington, John W. Hill of Philadelphia, and Rudolph Herring of New York, "to verify and make a report on or before March 1, 1904, to the committee on finance, as to the correctness of the estimates made by the director of public works."
Under this resolution the experts were employed and went to work. In the meantime, councils had received a petition from the Pittsburgh Section of the American Chemical Society, urging the establishment of a sand filtration plant; also a resolution of the Civic Club of Allegheny county, and a resolution of the permanent civic committee of the women's clubs of Allegheny county, urging sand filtration at an early date.
During 1903 there were 450 deaths from typhoid fever.
On February 27, 1904, the filtration experts made their report recommending a receiving basin, three sedimentation basins, a clear water basin, and forty filter beds. They also recommended sand filtration and covers for filter beds, but cut down the capacity of the various parts of the plant sufficiently to reduce the estimated cost by $700,000.
On March 31, 1904, the Bureau of Filtration in the Department of Public Works was created for the purpose of constructing these important works.
No further opposition of a serious character was met, and in July of that year a second bond election for $5,000,000 was held and passed by a vote of nearly two to one. These bonds were issued in September; plans and specifications for the enlarged plant were prepared as soon as possible; bids were advertised; and the contract was let on March 4, 1905.
With the final award of the contract the fight for pure water was practically won. Director Bigelow again stepped out of office in 1900 with the election of a mayor independent of either Republican faction; but the work of pushing the plant forward to completion was carried on by the Guthrie administration under the efficient supervision of Directors Clark and Shepherd, and Superintendent Knowles; so that by October, 1908, the plant was supplying a good quality of filtered water to the first twenty-three wards,—the old city.
