This plant Is up to date modern anu
economical and at present is about Two
thirds loaded at the peak of the loao'
We are basing above figures on the
present prices of material IN par'icu-
lar, wire and cast iron pipe.
The normal supply of water to the
city Is about 100000 gallons per day.
the initial supply Is equal to the pump
ing capacity; the expense of operating
above plants is very light, oas1ng coa'
supply at $3.50 per ton.
The operating expenses are item'zeo
as follows:

We made eleven tests Of the Light
Plant at different points and the great
est variation shown was less than two
volts, between the hours OF p. ILL., a'io
II D. M. Some Of the street lamps ex-
amined showing neglect IN Trimming
and care.
In our examination Of the water
Plant. which was rather extensive
Of discharge disclosed nothing, only
that the high tank was full OF wafer
and with the pump direct on the mains
and one opening at hydrant. the press
IRE at the pump remained normal win
vow little extra exertion on the pump.
The water in the reservoir was IN
no way effected and showed no signs
of sediment after the pull made on
it by the pump, but at one Oh the oeao
,nds. some distance from the plant, the
water showed some effects Of the
nounding, and it was slightly discoA'
ored.
- might be we'll to have The hydrant
flushed occasionally.
We found the following size anu
length of mains in streets and alleys
as follows:
500 feet 3-4-ln. pipe.
1890 feet lain. pipe.
25,540 feet Ain pipe.
$1,000 feet Gin. pipe.
4,460 feet sin. pipe.
1,4O0 feet 10-in. pipe
$40 feet 12-in. pipe.
200 feet 16rin. pipe
6S,O15 feet.
The above. mileage of mains and by
drant connections with specials and Ia
Dor on the $4,000 per ton basis
$18S.ss9.00.
The Heating Plant is valuable as
set to the plant, it might be extendet
to the City Hall, the Schools and Al
other Public Buildings. with no addi
tional care or expense in operating tn
plant. except the cost of the extensions
