Three hundred and twenty-eight deaths in the districts not supplied with filtered water, 328 funerals, 2,952 cases recovered, 2,952 loss of time. If the foregoing were calculated at the rate usually fixed by law, the money loss would be $2,022,448. A correspondent writes that “no progress has been made on the filtration work since Major Gillette was called in, and from present appearances none will be made until he goes out. The services of an engineer skilled in works of public water supply are needed to complete the filters. An army engineer, devoid of training or capabilities in this line of work, is bound to fail in his effort to complete a work wholly outside his line of study and experience. * * * Whatever fault may be found with the previous management, it at least had the merit of progress, and sought within the means at command to push the work to early completion. * * * Under the most favorable conditions the Belmont filter works cannot furnish more than 33,000,000 gallons a day, with difficulty in obtaining this quantity during the most adverse periods of the raw water. The consumption of water in West Philadelphia at times has reached nearly, if not quite, 40,000,000 gallons a day; and, aside from the present inadequate pumping capacity at the river station, the filters, as plaiti sand filters, cannot meet the present maximum demands. The preliminary filters, which are an absolute necessity, are held up. At the lower and upper Roxborough filters the like unfortunate condition prevails. The lower Roxborough filters have a daily capacity of 12,000.000 gallons, but lack of pumping capacity. The upper Roxborough filters have a capacity of 15.000.000 to 20,000,000 gallons a day, provided the raw water could be furnished from the Schuylkill river. This will require extra pumps and boilers, as recommended by Chief Hand in his report of operations for 1903—made to Maypr Weaver early in 1904. Tf the Roxborough filters were now being worked to their full capacity, at least 60,000 more people could be supplied with filtered water. This would meet the full requirements of the Thirty-eighth and Twenty-eighth wards.”
