This serritory, which is properly the future
Seattle. comprises some forty-six square miles
As was seen by the preliminary outline Of the
proposed works. there will be- to reach the ter
ritory within the city, as described, three dis
tisct services, supplying a. many districts. ly-

three different service districts grows out of its
topography. considered In relation to the source

reucers IL inexpedient, and almost impractic-
able to make one system OF distribution mains
cover the low and high territory alike In the
low regions the pressure would be too areaf, and
in the high regions too small 1t could have
been made into two districts instead OF three,
only for the fact that the extreme high eleva-
tons cannot be reach from the Swan lake re-
scryoir and Cedar river source, without going
much farther mp the river, and abandoning the
proposed use OF Swan lake, and vastly incress-
lug the expense II becomes cheaper to pump
from the hish-service gravity reservoir for the
small territory which II will not reach, rather
than TO have tried TO reach 1t sll by gravity.
The present corporate area is divided about -
follows between the three service di-tYicts:
Low-eravisy service district, comprising the
area below 20o feet elevation, $500 acres
High-srayity service district, comprising the
area between zoo feet and $50 feet elevation. $500
acres
High.pumping service district, comprising the
area above $50 feet elevation. go acres.
The low-gravity service district, which viii
generally include all the territory Of the city
lying below a level OF 200 feet, will embrace
part Of the depression extending from Jackson
and Sixteenth streets southeast to Lake WASH
ington, but its main territory follows the water
front from the south. reaching Is high as Fifth
and Co'umbia streets, widening like fan as We
60 north, and finally stretching from the eastern
shore OF Lake Union to Elliott bay. II
will follow around both sides Of Lake
Union. and one branch trends north
westward around the west side OF the
ridge west of Lake Union. these various
branches finally uniting in the Salmon bay de-
preston. To distribute water to this area from
the Iow-servce res ryoir, the mains viii have
"a pass through the central portion of the city.
and should be CAPABLE OF delivering su1dcient
water TO meet the requirements Of the low
grounds to the north. In making plans for this
district have kept this In view.
In the low-service district will be located man.
arteries aud large business houses, and In
ftct nearly all OF the large industries requiring
the most water Its service, therefore, becomes
the more important OF the three.
The high-gravify service district, - stated,
generally includes all territory lying between
100 and $50 feet elevation II comprises four de-
tached areas. separated from each other by the
low service strict The larger one OF these
areas lies mostly north OF Jackson street,
and extends from sixth AMI Columbia
streets 20 the Lake Warrington bluffs
1t also skirts the eastern bluffs OF Lake Union
Another one IL Q narrow strip of land, upon
which the iow-service reservoir 10 located
another, the hill upon which the Denny hotel
stands, aud stu another one 10 IN anuular-
shaped area In the extreme northern part OF the
city west Of Lake Union. These detached areas
are to be supplied from the high-gravify service
reservoir.
As before stated. the main supply pipe bctws
the two reservoirs will answer for distribution
main for this dis riot. II passes through the two
areas first mentioned. To reach the second two.
IL is proposed 70 lead as.x;een-inch pipe of from
the main supply at broadway aud Madison
streets and to follow Madison. Ninth, seventh,
Fourth Poplar and other streets 70 the area west
of Lake Onion. supplying in its course the Denny
hotel ridge.
The high pumping service district comprises
two distinct areas; one being the upper portion
Of the ridge upon which the hish-service reser-
voir II TO stand, and extending south of Mad
.son street into section 50; another being the
top Of The rligc west Of Lake Union.
To supply this service, 10 Is proposed, after the
new wo.ks are pnr into operation, 70 remove
portions OF the pumps. boilers. etc, from tue
pumping works on Lake Washington to the
hixh-scrysce reservoir. and establish pumping
works there. taking water from that reservoir
To reach the part OF the district west OF Lake
Union, pite will have u be laid across the
