Ma,Ston, Se,ccr Committee, Gentlemen"
Having completed the work entrusted to my
charge in the construction of town sewers sub
nit the following report for your examination
and approval.
After an examination If the work done last
season, the ground to be operated on this season,
and the plans prepared in 1886 it thought
necessary to enlarge the size of the pipe as pro-
posed for the North st. section from inch to IL
and 10 inch, which was accordingly done Also
it was thought better to abandon the proposed
brick main sewer from the corner of North and
Water SITS. across private property to Court St,
substituting in place of it pipe sewer Of suitable
dimensions by way Of Water and Court SITS
The reasons for this change are LIST 10 obtain
better service, as pipe is from 10 per cent. to
30 per cent. superior to brick in point of clcanli
ness I'd to avoid the construction of Il sewer
under dwellings, and the expense Of land dam
ages Bird an estimated saving i'll expense ofcon-
s,ructOn Of $500, as pipe can he laid at "A less
expense than brick, and the building Of the II
inch sewer in Water ST., as laid out, is now OBJ
waited.
As the brick outlet sewer built last season,
does not correspond with the line laid out
upon the plan, touching it only at the extreme
outlet it has been necessary to establish IA new
line and new grade from Water to High st. and
the Water st. line is made about 40 #. longer
than necessary. This has involved extra
expenditure on the work Of this season of prob
ably $500, and has Obliged us to cross private
property for short distance.
The amount of work done this season is
follows. the streets severed are North st. to
Leayitt, Leavitt to the schoohouse, and Fast
Water st. from North to Court st. Amount of
excavation in ledge, Water ST., AS Gu. yds.,
North St, y Gu. yds.; in earth, Water ST., 766
Gu. yds, North St, 1927 Gu yds., Lcayitt ST., $40

North st. Coz #. II in, Lcayitt st. 3iS #. in.
Total pipe laid, 1908 #. Man-holes built, b,
Catch basins built, II.
The man-holcs are covered with strong CRATES
SCI in : lnic, instead of with tight covers and
will provide ample ventilation TO the sewer.
The cat III basins are connected with the main
sewer by 4 inch pipe, thoroughly trapped to
prevent the escape of foul gases, by the side
walks.
The amount of money expended is as follows
Ter pipe, brick, granite, cement and CRATES,
Sls9a. 80
For labor as per pay roll and time bills, 356i.i6
For sun1ry expenses and supplies, a3i.l2
For engineering, 432.OO
Total, $6i26.T
Received from sale Of stone, 1900
Value = pipe, tools, ETC., on hnsd, l21.0O
Total, $l5l.0O
Actual cost Of sewer, G272.77
Amt Of appropriation, 5000 90
Oyerdrawn Sl272.77
TIN, amount will be reduced By the proceeds
of entrance fees for house connections, Of which
| c1nno' give an accurate account, as that mat
tel is in the hands Of the municipal authorities.
There have also been furnished about 200 loads
of broken stone, etc, to the street commissioner,
of which no account is made here, as the repairs
toithe street necessitated by the settling of the
trenches will come under his department.
The average cost of eNeayatng, back filling, |
grading, etc, has been, for ledge, 500 per Gu.
yd, fol earth, Sl.l0 per Gu. yd. The nature of
the ledge encountered has been very refractory, |
such THAI it could not be drilled by steam, and
-hc cost Of handling it has been somewhat above
the average, although by no means excessive.
The average cost Of construction per running
foot has been, for Water st. $500, for North &
Payitt sts SID
The capacity of the sewer on North st. is
5000 #. per hour, or 432 600 feet per day of
a hours. The capacity Of the Water st. sewer
IS 36 36O Gu. #. per hour, S72,6lO feet per day
If u hours. Their combined capacity is sutfi-
nch pei day from an area of three hundred acres,
with population of 5000. Although heavier
ain-falls are frequent, the above amount is all
hat will find its way into the sewer under ordi-
lary circumstances,
More than ordinary care and attention must
,e given to the cleanliness of these sewers, until
he designed system is completed, asithey will
lot be called upon to do the full amount of work
Or which they designed, and will become
oul quite rapidly in consequence. Especially
this true Of the 20 inch sewer on Water St,
'hich has low grade, and will only be required
/ present to do the work of an s inch sewer.
The material used in construction has been of
superior quality. The pipe furnished BY the
'ortland Stoneware Co., has been of an excel
'nt grade and was subjected to rigid inspect
IN. None has been accepted which was not
ound, smooth and Of perfect shape All other ,
laterial has been of a character entirely suitable
n the work. According to my best knowledge ,
nd belief, the construction has been thorough, !
nd in accordance with the most advanced prin- ,
piles of sanitary engineering.
| would beg leave to recommend here that a
roper set of regulations be adopted in regard to
Il house connections and strict compliance :
18th them be enforced by the municipal author /
les also that all entrance fees be fixed at a .
ertan rate per foot of street frontage.
In conclusion, | would urge the necessity of '
irrying forward the work Of sewerng the town, c
} speedy completion, many sections yet
main in absolute need of proper drainage. h
