PUMPS AND MACHINERY
a letter from Mr.. George w. Wright
engineer at the pumping works. stated
III ustdli me condition of the various
machinery and the capacity of tho
pumps and engines. some of them ned
repairs lie recommends that an addi-
tionai engine be bought for the filter
pant; The pumping capacity there
now is oOo0, 200 gallons daily. If any
accident should happen the filter plant
would be out of service until repairs
could be made.
TO STOP WASTE.
city Engineer Brooke spoke of some
appliance TO stop the waste of water.
| He told of experiments made in New
York among % houses where the con-
| sumption of water had been over 100
gallons OF water per capita. Meters
We're put in and the consumption of
water decreased TO 60 gallons. That is
| u.
| capita.
METERS OR MORE WATER.
Mr.. E. l.. Mayer spoke of the cost of
meters for this place as being 100000
FOR the piston meter and $4,000 for the
disc meter. He said that nearly all of
| the large cities used the disc meters
| because they are much cheaper and
with filtered water do equally good SER
| vice
MIR. Mayer said the practical cues
amount of money. say. $500, 900 to allow
citizens to waste all the water they
wish or To put i'm meters to stop the
waste. Now we are pumping 6,00e. 200
be sufficient.
COST OF MAINS.
The meters are not made of perisha-
BILE materials, therefore they are not
short lived but viii last longer than
the pipe connections will last, or - to
10 years.
AS one of the elements of cost of the
other method of remedying the low
pressure by other means than stopping
the waste of meters, he said that a
piper line at 100000 a mile would cost
$50 600 exclusive of the right of way
MIR. Brooke mentioned the case of At
lanta as having used 100000 gallons
of water before putting in meters and
less than one-half Of that amount
afterwards.
AN EXPERT NEEDED.
Capt w. w. Old said the committee
is called TO decide whether to employ
an expert to report on the condition of
the water supply and some means of
stopping the waste.
MIR. PENDER'S PROPOSITION.
Mr.. Beaman moved that the commit
| toe should decline to entertain the
| proposition to sell the city water works
| or Ia consider a proposition TO buy the
| Norfolk County Water Company's sup
ply. This was the proposition of Mr..
