tOput In a Filtration PIant-COmmtt
 to Adopt.
 The directors of the New Haven Wa.
 ter company have decided that the
 water supply from Lake Whitney shall
 be filtered and plant will be installed
 as soon as it can properly be done II was learned last evening that the com mittee on filtration, which consists of
 Messrs Whitney, MerWin, Watrous and DeWell who have seen and inspected filtration plants in other cities, will make their report to tn board of direc- 1 tors soon, probably ill a week, as to what filtration system they consider best and most feasible and effective
 The directors will act at once upon the report and decide what system to use and the work of putting in the plant will be started as soon as possible. It will take year or less to get the plant ill operation. The sand and mechani- cal systems are both under considera- | ton.
 | In the one, slow filtration through
 
 the dangerous pathogenic germs, and from the filters the water is pumped to the distributing reservoir. By this method the water flowing on to the sand leaves a depost--a sort of gelatin ous ubstance forms on the surface of the beds which restraints the entrance of all harmful matter and the effiuent from the filter analyses as nearly pure or at least free from harmful germs. It is the custom to have several of these sand beds so that while one is being cleaned, the others keep up the supply. This system is the oldest and is in use in many continental countries, and is generally more familiar to the average citizen than any other.
 The other system, known as the Am erican or the mechanical system, is more modern and is being used and de- veloped in this country especially. By this plan a coagulent Is introduced which is mixed with the water before it is put through the filter and which hastens the formation of the substance on the sand that restraints the entrance of the bacteria. There are also me chanical systems about to be operated at Binghamton, N. Y.; Kankakee, Ill.,. and other places, all operating under the coagulant plan. The cost of either system Is very considerable. } It is un- derstood that the directors of the water company will install a filtration plant upon the Whitney supply, but un- til the report of the committee is for mulated nothing will be given out as tn hn Ic tO ha informed estimate the cost of q sand pant for the Whitneyville supply as about S900OOO If decided upon it would be located at the west of the trolley line at the foot of the Lake Whitney hill. The water would then flow by gravity on to the filters, and from thence also by gravity to the l pump chambers. from which it would | be forced to the reservoir.
 The we'll known expert George w. | Fuller, recommended the early filtra- ton of the Whitney supply, but upon the Saltonstall, Maltby and Winter green sheds there are at present no and these sources of supply Mir. Fuller considered ideal The Daw- son supply, from which 1t was claimed the typhoid epidemic originated has since that time been very much inn proved, and the most of this shed is absolutely in the possession or under he control of the water company, and Mr. Fuller considered that at present { was impracticable to introduce any modern filter system there that would ,e satisfactory. In Boston, under the Metropolitan water board, whole owns have been removed and reser- 'oirs built with settling basins, etc., ut they do not filter any of their sup dies, relying upon the sedimentation 'asins and a careful supervision of heir water sheds
