this morning synopsis Of the report Of Engineer
Elicit and ell and Superintendent Davis, made
the Watering Committee Of the City Council, q
| TO the best mode OF enlarging the City Wate
Works The first and most jadicious plan for oh
tanning the best results with the smallest outlay
| contains the following recommendations:
To divide the distribution into an upper and
lower service. TO construct a new reservoir, o
ample dimensions, on Oregon Hill, to receive ant
hold the supply fer all that portion Of the city
which will be within the lover service, and which

sut face OF the reservoir, and ITO feet above mean
tide. To lay down q 20 inches main from point
north OF the canal, the line Of the present al,
cending mains, through which the water will be
forced into the receiving reservoir Oregon Hill;
and 10 inches ser7cs main, from the receiving
reservoir TO the lower service pipes To raise the
surface of the present reservoir 10 feet and at
some future, but very remote period, construct a
new reservoir along side Of it, of greater dimen-
sions than the present, for the supply Of the up,
per service.
OF THE BELviDEHE RESERVOIR.

The report in speaking of the effect which will
be produced by this Reservoir on the upper SER
vice, says:
By means of the proposed division of the service,
We shall relieve the mains which now supply the
whole city. of about three.fourths of the present
will be that the pressure the pipes in the pper
service will be increased. and the water will c0rise
guently ri.e on the highest parts of shockoe Hin
But allowing for possible errors In the estimated
consumption of the lower SERVICE nay still safe
~ assume that the increase of head which will be-
gained for the upper service by this separation. vii
be not less than Is feet.
The upper part of the city will thus be 30 far re-
lieved that every consumer there will be able to OBJ
tain an ample supply of water ut all times; though
t will not be drawn anywhere at as great an eIeva
ton a. would be desirable.
The water will be delivered. also, by This improve
ment alone ia much better condition than 1t is now
since it will stand our times as long in the reservoir

large main 600 feet shorter than the small mainI
through which 1t is now all lifted, will much re

considerable time to come

re1uced lift will be about % per cent and they will
certainly be capable, with the aid of the large res

ENLAR0aaENT OF TIE PRESENT REssKyoIR
But after the completion of the new reservoir on
Oregon Hill the works will still he imperfect in on
particular This reservoir will only serve to increas
the elevation at which water will be furnished I,
consumers in the upper portions of the city from
to l9 feet; which. to avoid possible disappointment
We estimate at Is feet-while greater increase 0
the height of delivery is all hands, admitted tt
be desirable. This additional elevation can only b,
obtained by raising the present or building q new
reservoir.
We propose therefore. as involving the least ex
penditure that can be made, compatible with the
condition that AL parts of the city shall be furnished
an abundant turply of pure water at an ample Gle
ovation. to raise the present reservoir ten feet
This increase in the height of the reservoir added
to what we shall gain for the upper service by the
construction OF the new reservoir ON ORE gon Hill
will enable us to deliver water tn those consumers
who now suffer most on the highest parts of shoc
