amount and kind of work done with
iremized cost of same should be kept !
The engineer should be provided with /
all necessary tools. including disks /
and set of pulleys, a set of wooden /
balls and floats and several lengths !
of jointed rods. He should also have |
TWO or three large nozzles and sew
eral sections of fire hose. The lat |
ter can always be taken from the |
fire department, selecting only such as
is unfit for fire service.
5. While line B costs somewhat |
more than line A. I consider the ad-
vantages to be gained by the outlet
being located $500 feet further down
the river and below the principal
wharfs and landings to be much great |
! er than the additional cost.
If you decide to continue the use
of your present system for both house
sewage and storm water strongly
recommend the selection of line b.
| 6. However as your city has done
but little permanent paving | think
the time opportune for you TO consider
the advantages to be derived from in
stalling a separate sanitary sewer 10

yosr present system for drainage of.
saep and storm water | estimate that
for, not to exceed $S5.000.0O you can
build a man outlet sanitary sewer.
and extend same from outlet $500 feet
below Tenth street to railroad track
Just below Fortieth street and also
connect each house with the new sys-
tenn that is now connected to your
present system.
| This Main Sewer is calculated TO al
low a water consumption OF 100000
gallons which is sufficient to give a
population Of 10000 people an average
Of $50 gallons per day.
| This cGntemplates the installation of
a sewage pumping station at the lower
end of town Just inside the levee.
| The pumps 10 be of the centrifugal
type operated with electric motor or
gas engine. preferably the former as
! the city can install plant for light
| ing With but little additional cost
| for boiler capacity and building.
4 give below statement Of some Of
the facts and conditions that occur
to me as worthy of attention in con
sidering of plan to be adopted.
4 (a) You have but little permanent
paving and the installation of a sep
arate sanitary sewer system can pro-
| coed in advance Of street paving and
lat minimum expense.
a tbl The present system is not de-
signed to carry house sewage. The
grades are toe light to prevent de

TOO large to admit of economical reg

The manholes act as catch basins
and cess pools in time of light flow
instead Of providing an uninterrupt
