Saugus sewage into the main sewer in Central street, than to attempt to build a gravity sewer along Prankers Pond. The pumping station is to be westerly of Central street near the small artificial reservoir which was at one time a part of the Lynn water works system. From the pumping station the sew- age is to be pumped through a force main extending south- easterly in an old right-of-way to the upper end of the North Saugus Main Sewer in Central street.
The pumping station will consist of a wet well, dry pump well, pumping equipment and superstructure. The pumps will be two single stage, vertical shaft, contrifugal pumps with a rated capacity of 400 gallons per minute. They will be operated by two 25 H.P. motors automatically con- trolled.
LINCOLN AVENUE MAIN SEWER-EAST SAUGUS TO CLIFTONDALE. The Lincoln Avenue Main Sewer will serve that part of East Saugus and Cliftondale included in Drainage Districts Nos. 14, 15 and 16. It will extend from the Saugus River Intercepting Sewer near the intersection of Chestnut street and Lincoln avenue, southerly in Lincoln avenue, easterly in Vincent street, southerly in Johnson street, easterly in Ballard street, southerly in Greenwood avenue and Walcott road, north- westerly in Guild road and westerly in Lincoln avenue to Cen- tral street it will be 15 inches in diameter from the low end to the junction of Guild road and Lincoln avenue, 10 inches in diame- ter to Lewis lane, and eight inches in diameter to Central street. The upper end of the main sewer in Lincoln avenue, westerly of Guild road, is to be at a normal depth. From Guild road to the lower end the sewer will be comparatively deep. Lateral sewers are planned to enter the main sewer from numerous streets in District No. 14.
"LITTLE ITALY." The Sewage from District No. 15 is to be discharged into the main sewer at the intersection of Guild road and Richard street. District No. 15 is nearly level and only a few feet above tide water. The Lincoln Avenue Main Sewer would have to be much deeper than is otherwise neces- sary, to receive the sewage from this district by gravity, and it will be more economical to build a small pumping station and raise the sewage of this low area than to construct the Lincoln Avenue Main Sewer at a greater depth.
The pumping station for this district is to be at the intersec-

tion of Bristol street and Sussex street. A force main is to extend from the pumping station along Bristol street, Bentley street, Halstead street, and Richard streets, to the Lincoln Avenue Main Sewer in Guild road. This force main will be of cast iron pipe four inches in diameter. The pumping station will consist of a wet well, dry pump well, pumping equipment and superstructure. The pumps will be two single stage, vertical shaft, centrifugal pumps with a rated capacity of 250 gallons per minute. They will be operated by two 10 H. P. motors, automatically controlled.
LEWIS LANE SUB-MAIN SEWER. Drainage district No. 16 includes the easterly side of Baker Hill in Cliftondale and con- siderable area which is only a few feet above tidal waters. Although the general plan shows a large number of streets in this district only a few have been built up. Sunnyside Park, Morton avenue, Endicott street, Fermont avenue, and adjacent streets are fairly well built up and this section is in need of sewers. Lateral sewers have been laid out in these streets with a sub-main sewer extending from Morton avenue, across private property about midway between Lewis Lane and Lincoln avenue, to the Lincoln Avenue Main Sewer at Seagirt avenue.
When sewers are required in the remaining portion of this district it will be necessary to build a pumping station at a central point along Saugus avenue and pump the sewage through a force main in Saugus avenue and Lewis lane into the Lincoln Avenue Main Sewer at Seagirt avenue. It is doubtful if this section will be developed sufficiently to warrant this construction for many years in the future.
INITIAL CONSTRUCTION
The need of sewers at Saugus has been pointed out in the earlier pages of this report ; but it would be a large and expen- sive undertaking to construct sewers for all of the built-up parts of the town at one time. Sewers are, of course, needed more badly in some sections than in others and a sewer system might well be built by piecemeal coustruction, the sewers being built first where most urgently needed. This need is greatest at Clif- tondale, Saugus Centre and East Saugus where the population is most concentrated and where present methods of disposing of the sewage are both unsanitary and unsatisfactory.

TOWN DOCUMENTS.
[Dec. 31
The initial construction of sewers should include the following parts of the proposed system :
(1) Main Pumping Station at East Saugus and suffi- cient pumping equipment to care for the volume of sewage collected in the sewers built at the outset.
(2) Temporary force main from Main Pumping Station at East Saugus to Summer street sewer at Austin Square in Lynn.
(3) Saugus River Intercepting Sewer.
(4) Cliftondale Main Sewers.
(5) Cliftondale Pumping Station, force main in Mt. Vernon street and Whitney street, and Whitney street Sub- main Sewer.
(6) Lateral sewers and service connections at Cliftondale.
(7) Lateral sewers and connections at Saugus Centre.
(8) Lateral sewers and service connections at East Saugus.
Construction of the parts of the sewer system above outlined will serve about 5,000 people in the three most thickly populated communities of the town.
CONSTRUCTION COSTS,
In estimating construction costs due consideration has been given to local conditions and a reasonable allowance has been made for rock excavation and for wet trench work; no allow- ance has been made to cover the expense of land takings or damages. More accurate knowledge of the factors affecting excavation and foundations should be obtained by making bor- ings or by digging test pits along the routes of the sewers pre- vious to the preparation of detail plans for the actual construction work.
In making use of the cost figures given herein, it must be recognized that methods of construction whether by contract or by municipal forces, are apt to have a material effect upon con- struction costs ; it often happens that extensive sewer work can be done most economically, by letting the work to contractors having complete and efficient equipment to handle it. The cost figures given herein are based on the assumption that the work will be built by contract.
1925]
PLANNING BOARD REPORT. 145
Estimated costs are determined from current prices, which are constantly changing; this constant fluctuation in prices may make considerable difference between the present estimated costs and the actual construction costs if the carrying out of the work is long postponed. Estimated costs may be somewhat affected by minor changes in the layout of sewers, found desirable as a re- sult of the more detailed studies which must be made for the preparation of construction plans.
In preparing our estimates of cost for the proposed work we have adopted prices which we believe are high enough to cover the underground and other conditions that cannot be definitely determined in a preliminary investigation of this nature. During the past year bids upon sewer construction work have varied greatly, a difference of 75% being not unusual in the bids for a given job. We have no doubt that prices somewhat lower than those used in our estimates might be obtained if the proposed work was to be contracted for during the coming year.
Preliminary estimates of cost have been prepared for the part of the proposed system recommended for initial construction as well as for the entire sewer system shown on the General Plan, page R-66. These cost estimates are given on the following pages.

PLANNING BOARD REPORT.
1925]
Some municipalities are much more favorably situated for the installation of a sewer system than Saugus is ; this is due largely to the geographical location of the built up parts of the town, to the natural topography, to the soil conditions, and to the large area over which the development is spread.
At Saugus the built up areas are located away from the shore and expensive provisions must be made for disposing of the sew- age ; the natural drainage routes are along flat valleys, where sewers must be built either deep or large to provide the neces- sary capacity ; some areas are too low for their sewage to reach the main sewers without pumping ; considerable rock excavation will be encountered in the trenches and in many sections water will be encountered ; the populated areas are so separated that considerable lengths of sewer extending between these areas will serve only a very small number of people ; for the suggested "Initial Construction" about eleven miles of sewer will be re- quired to serve only 5,000 people in the three most populous communities, and about 57 miles of sewers will be needed to serve the entire area which is built up at the present time.
FUNDS FOR SEWER CONSTRUCTION
It has already been explained that the General Laws of Massachusetts permit a town to incur debt within its debt limit for the construction of sewers, provided this debt is retired within a period of thirty years. This privilege is commonly exercised where extensive construction work is undertaken, involving a considerable outlay of funds.
If a town cannot raise the necessary funds without exceeding its allowable debt limit, special action by the legislature must be resorted to. Such legislative action would have to be obtained by Saugus if the town decided to build the sewers suggested for "Initial Construction."
Chapter 83, Section 23, of the General Laws, provides that part of the expense of laying out, constructing, maintaining and repairing common sewers shall be paid by the town, this part to be not less than one quarter nor more than two-thirds of the cost as above stated, the actual proportion to be determined by vote of the town.
Chapter 83, Section 14, 15 and 16 of the General Laws pro- vide that the remainder of the cost may be assessed upon own- ers of land benefited, by a fixed uniform rate, based on the estimated average cost of the sewers; this assessment may be
154
TOWN DOCUMENTS.
[Dec. 31
according to the frontage of the land along the street in which the sewer is built, according to the area of the land within a fixed depth from the street, or according to both such frontage and area of the land.
The cost of service connections from the common sewer to the property is paid for by the property owner.
COMPARATIVE COSTS OF SEWERS AND CESSPOOLS
Estimates of cost have been made to determine how the aver- age annual cost of the sewers suggested as "Initial Construc- tion," to serve 5,000 peeple, will compare with the average annual cost of cesspools to serve the same population.
SEWERS. The estimated annual cost of the sewers includes both, an allowance for the amount to be paid annually as principal and interest charges upon 30-year serial bonds issued to cover the cost of construction, and an allowance to cover annual operating and maintenance costs. The annual cost figures arrived at are intended to be a fair average for the 30 year period during which the bonds for constuction are being retired.
The construction costs include all the items suggested for "Initial Construction" and in addition an amount of about $43,300 which Saugus might reasonably be expected to pay to Lynn for the privilege of using its Pumping Station and Outfall Sewer Works.
It is assumed that the cost of constructing the Main Pumping Station, at East Saugus, and the Saugus River Intercepting Sewer together with the amount paid Lynn for the privilege of using its Outfall Sewer Works will be borne by the entire popu- lation of Saugus, and that the 5,000 people served by the "Initial Construction" will stand only their proportionate share of the total amount. The proportional share for 5,000 people will of course become gradually less as the total population of Saugus increases, varying from about 40 per cent at the outset to about 20 per cent thirty years later, or an average of 30 per cent throughout the 30 year period. It is assumed that the cost of all other sewers included in the "Initial Construction" together with all operating and maintenance costs charged to the "Initial Construction" will be paid entirely by the 5,000 people served.
The costs are summarized in the following items ;

CESSPOOLS. The estimated annual cost of cesspools includes both an allowance for cleaning cesspools and an allowance for cesspool replacements.
Five thousand people served by cesspools will require 1,000 cesspool installations, on the basis of one installation for every five people. The annual cost of cleaning cesspool installations is taken as $ 8.00 per year as determined by our investigation of cesspools ; at this rate the total annual cost of cesspool cleaning would be $18,000 for 5,000 people. The average cost of build- ing new cesspool installations, including overflow provisions, is $61.00 each. Assuming the average life of a cesspool installa- tion to be twenty years the total annual cost of replacements for 1,000 cesspools would be $3,050. The total combined annual cost of cesspool cleanings and cesspool replacements would therefore be $21,050.
SEWER COSTS VS. CESSPOOL COSTS. Comparing the cost of the "Initial Construction" of sewers to serve 5,000 people with the cost of cesspools to serve the same population, the esti- mated total annual cost for sewers averages $28, 132 and the total annual cost for cesspools $21,050.
The "Initial Construction" of sewers will therefore cost about $7,080 per year more than the cost of cesspools, or $1.42 more per person, per year.
The benefits and advantages derived from the installation of sewers would certainly be well worth their additional cost and without doubt this additional cost would be more than offset, at an early date, by increased real estate values.
CONCLUSIONS
(1) The Town of Saugus, a growing suburban community, has no modern municipal sewer system ; a few unauthorized private sewers have been built, but these are small and of doubtful value as part of a comprehensive sewer system.
(2) Practically all of the "built up" section of the town rely upon cesspools for the disposal of sewage; the dwellings in the outlying sections still make use of the old fashioned out- house or privy.
(3) In many sections of Saugus, the nearness of the ground water to the surface, the imperviousness of the soil and the exis- tence of ledge rock, are conditions which prevent the efficient
