  Genesee 
  river. 
  In 
  considering 
  the 
  Genesee 
  river 
  as 
  a 
  source 
  for 
  

   a 
  temporary 
  supply 
  for 
  Rochester, 
  the 
  intake 
  might 
  be 
  located 
  

   either 
  in 
  the 
  vicinity 
  of 
  the 
  south 
  end 
  of 
  the 
  Erie 
  railway 
  bridge 
  

   or 
  at 
  Elmwood 
  avenue. 
  The 
  former 
  location 
  is 
  nearer 
  to 
  Mount 
  

   Hope 
  reservoir, 
  but 
  the 
  proximity 
  of 
  the 
  oil 
  works 
  and 
  a 
  storm 
  

   outlet 
  for 
  a 
  new 
  sewer 
  on 
  the 
  west 
  side 
  makes 
  the 
  Elmwood 
  

   avenue 
  site 
  somewhat 
  more 
  desirable. 
  The 
  latter 
  is 
  about 
  1.63 
  

   miles 
  from 
  the 
  reservoir, 
  and 
  the 
  usual 
  low- 
  water 
  surface 
  of 
  the 
  

   river 
  is 
  about 
  128 
  feet 
  below 
  the 
  same. 
  To 
  render 
  the 
  water 
  fit 
  

   for 
  domestic 
  use 
  it 
  would 
  need 
  to 
  be 
  filtered, 
  and 
  in 
  this 
  respect 
  

   it 
  stands 
  on 
  practically 
  the 
  same 
  scale 
  as 
  the 
  water 
  of 
  all 
  the 
  

   other 
  streams 
  previously 
  mentioned 
  and 
  that 
  of 
  the 
  Erie 
  canal. 
  The 
  

   principal 
  advantage 
  of 
  this 
  site 
  was 
  that 
  the 
  pumping 
  station 
  

   would 
  become 
  available 
  for 
  supplying 
  water 
  to 
  South 
  Park 
  as 
  

   soon 
  as 
  its 
  use 
  for 
  supplementing 
  the 
  flow 
  from 
  Hemlock 
  lake 
  

   ceased; 
  also 
  the 
  force 
  main 
  would 
  serve 
  as 
  a 
  future 
  distributing 
  

   pipe 
  for 
  the 
  southern 
  districts 
  of 
  the 
  city 
  on 
  both 
  sides 
  of 
  the 
  

   river. 
  All 
  of 
  the 
  plant 
  except 
  the 
  filters 
  would 
  thus 
  have 
  had 
  a 
  

   permanent 
  value 
  for 
  two 
  city 
  departments. 
  The 
  estimated 
  cost 
  

   of 
  the 
  works 
  with 
  a 
  12-inch 
  force 
  main 
  and 
  including 
  filters 
  was 
  

   about 
  |51,000, 
  but 
  if 
  the 
  force 
  main 
  were 
  increased 
  to 
  16 
  inches 
  

   in 
  diameter, 
  the 
  cost 
  was 
  estimated 
  at 
  f 
  60, 
  000. 
  With 
  the 
  filter 
  

   plant 
  rented 
  for 
  a 
  few 
  years 
  the 
  costs 
  would 
  be 
  about 
  $15,000 
  less 
  

   than 
  the 
  amounts 
  named.
