The average per capita consumption.
based on an estimated population Of $1,000
was 9S5 gallons divided as follows: Man
ufacturing industries, 5s gallons; domestic
service 6s.5 gallons.
The total number Of meters in use on
June 30, 1908, was 4949 showing an in
crease Of SOC for the fiscal year, about $500
Of which are on private residences. The
metered service represents SIT per cent.
Of revenue received for water rents; 51.1
per cent. of the quantity consumed, and
27.6 per cent Of the number Of services in
use.
During the year 1892 feet Of new mains
were laid Of which 1868 feet were for the
high service. and 6939 feet new for low
service. OF the above quantity 7022 feet
were to replace smaller mains. In addition
to the ordinary extension Of mains, there
were laid during the past two years 9l22
feet Of 42 and 43-inch. and 1O.sls feet OF
4S-inch mains.
Including the larger mains as part OF
the permanent distribution system. makes
a total Of 1857 miles of mains laid in the
city, of which 51.1 per cent are S-inch in
diameter or over.
There were 50 new gate valves placed on
mains. 81 replacing old ones. making the
total number Of gate valves in use. There
were IL new fire hydrants added during
the year, and IA old ones were replaced.
the total number Of FIRE hydrants in SER
vice being sO2.
A total of S86 new services were laid.
and 1OS old services were renewed.
Water has been supplied from the new
reservoir, and through the new system
since the early part Of 1908. during which
time the water supplied has had the bene-
fit of the partial or preliminary filtration.
The thirty-flve million gallon reservoir; ;
the 43-inch forcing main, and 4S-inch dis
tributing main, the new pumping station
and the two twelve million gallon pump
ing engines, the new boiler house equip
ped with four 800 horse power boilers. to-
aether with the coal storage vaults. and
the preliminary filter, have all been COM
pleted and put in successful operation.
AS was to have been expected there were
a number of very small joints leaks along
the steel mains. confined almost exclusive
ly to these portions Of the mains which
had not been tested prior to placing in ser
vice. AS such leaks have been discovered.
they have been repaired with but slight
trouble.
Complete the Filter.
While the new system is in active oper-
alton, and doing effective service, It must
I not be considered as complete until the
final sand filters are constructed. Every
step in the designing Of this plant has
been taken as part of a filtration sys-
tenn having in view the use Of slow sand
filters for the final publication Of the
water supply. and until these filters are
built and in operation, IT must be looked
upon as an uncompleted design and as
such it may be open TO the criticism OF
either OF the two classes Of individuals

Attention should be called again to the
possibility of utilizing the power develop
ed from the flow of water from Porter to
Cool Spring Reservoir. This proposition
was clearly set forth in the report for
1906, and it is hoped that the scheme
therein outlined will be carried out event
ually.
A new gate house at Cool Spring Reser-
voir is necessary under the new system.
and plans have been partially prepared
for this work with a view TO having all
the gate valves operated by gecVed stand
ards from the main floor. Space in the
gate house was provided for accommodate
ing the turbine for developing the water
power to which reference has previously
been made. and also for accommodating
the generator and switchboard necessary
for utilizing said power. Provision is also
made for set of steps in combination
with the gate house leading up to the top
Of the reservoir embanlkment.
In Connection with this work an emerg-
ency overflow should be provided for Cool
Spring Reservoir; draining into the sewer
at that point
The question of the purchase Of the Lea
water rights being still in abeyance. moth
ing definite has been done. relative to de-
veloping the available water power at
Brandywine pumping station. The present
water wheel has very nearly outlived its
usefulness and it viii be incumbent In this
department 70 replace it with more mod
ern machinery in order to attain the fun
benefits which the water power win af-
ford. The main question to consider is
whether the development is to be made
for all OF the water of the Brandywine,
or for half OF it, and as soon as this is
definitely decided, the designs for the
work SHOULD be completed and Ene new
turbines and pumps installed without
delay.
