In the Merchants' Association report it is stated that an 

 additional water supply for Xew York city, adequate until its 

 population shall increase to 18,000,000, can be obtained from, 

 the Hudson river above Poughkeepsie, at which point it is pro- 

 posed to build pumiping sin l ions and filter beds on the cast side of 

 the river, together with an aqueduct to the northern limits of the 

 city, where a reservoir would be constructed. This plant should 

 be capable of supplying 250,000,000 gallons daily, although it is 

 not proposed to build a plant capable of delivering at first more 

 than 100,000,000 gallons daily. 



In order to prevent the water above Poughkeepsie from becom- 

 ing brackish, by reason of taking so large an amount of water 

 from the river at this point, it is proposed to build in the Adiron- 

 dack a number of the reservoirs discussed on a preceding page, 

 in which may be stored Mood-flows during the spring months. 

 This water is to be delivered into the river during the dry season, 

 thus keeping the How uniform throughout the year. 



As incidental benefits, the navigation of the Hudson from Troy 

 down will be considerably improved, together with a prevention 

 of floods at Albany and places in the vicinity, as well as pro- 

 vision for a uniform flow for mill owners at various points 

 higher up. 



It is also suggested that water be taken from the Hudson at 

 Hadley, as indicated in the discussion of the Schroon valley 

 reservoir. 



The annual cost of taking water at Poughkeepsie, including 

 operation and maintenance, will be |28.33 per million gallons 

 for 250,000,000 gallons daily. The annual cost for the same 

 amount from the Adirondacks, including interest, operation and 

 maintenance, will be $30 per million gallons, while to furnish 

 500,000,000 gallons from the Adirondacks, the yearly cost after 

 construction will become |29.25 per million gallons. 



The Committee on Water Supply of the Merchants' Association, 

 however, considered that there are certain advantages in the 

 Poughkeepsie plan over either the Cats-kill or Adirondack in 

 that: 



1) The ultimate first cost of the Poughkeepsie plan would 

 be less.
