The following report by superintendent Valid

ment, was read:
In obedience to your instructions to present
70 70 you report touching upon the installation
vi the new o,oOO,0OO-gallon Holly pumping en-
CINE at the Lake Washington station, together
with the necessary cost 10 the city in eonnection
herewith. we beg TO report:
In order TO clearly present the matter you will
permit US 10 review the system in its present
state, and then consider the addition of the new
HOLY pump, with a guaranteed daily capacity
OF 100000 United States gallons in twenty-four
hours. $500
THE PRESENT sYsTEM
we now have at the Lake Washington pumping
station the following pumping capacity:
Dow pump $50, 900 United States gallons per
gay, ortwenty-four hours.
Worthington pump, 100000 United States
salIons per day, or twenty-four hours.
a. ne nave pipe capacity from said station to
the supply system, to deliver the product OF the
ABOVE pumps, as follows: A twelve inch force
main from said station to reservoirs, into which
lne DOW pump can deliver 2,500,000 gallons per
cay Then we have one other force main from
said station, sixteen inches in diameter, leading
70 70 iesler avenue, into which the two Worthing-
TON pump can deliver 100000 gallons per day.
AS shown above, we have q carrying capacity
70 reservoir, viz:
Gallons.
Through twelve-nch force main direct 2. SOC. 600
Ahrough slxteen-ineh force main, direct
oAu ihoifecs,.......... 4,0OO,OOO
Total maximum capacity. $500, 600
ms Is all these force mains should ever be
called upon to carry.
The delivering capacity through the thirty
men main from the reservoir to the city is
ao,Ooo,oco gallons per day. The foregoing is the
present condition of our system. Now, the new
hoiy pump, with It's guaranteed capacity of
2p;oooOo0 gallons per day, must be accommodated.
Hence the
The first thing necessary for the city to fur
nlsh in connection with the new Holly pump,
Is thirty-six inch pipe from deep water to sup
ply its suction. Length thereof about SS5 feet
SO as to reach out where water is ninety feet
deep. This pipe together with the necessary
inlet IN lei, well both complete for pump will cost
other pumps If desirable).s
Assuming these pipes and inlet well finished
and the Holly pumps suction connected there
with and ready for duty, we are then prepared
to pump daily L, 100000 gallons, but we have
only carrying capacity to the reservoir from
Lake Washington pumping station of 6,500,00O
gallons as shown.
Additional pipe capacity to reservoir to carry
the increase OF new Holly pump must therefore
be furnished by the city. This will require a
twenty-inch main from Lake Washington
pumping station to the reservoir, distance of
1900 feet costing $4,000 This force main can
also serve as distributing main for the south
portion Of the city.

Or Sal $40 being the amount required to be
expended by the city to utilize the additional
capacity of the new Holly pump.
The above expense is not without source of
ultimate and in fact almost immediate profit to
