PLANS

FOR

SYSTEMS OF SEWERAGE

AND

SEWAGE DISPOSAL

MASSENA, N. Y.

Separate sewer system

Plans providing for a separate system of sewers were approved by this Board February 14, 1900.

Both the Raquette and Grasse rivers flow through the village in an almost due easterly direction, and so as to have almost half the village area between them.

The sewage of the northerly half of the village will be discharged by gravity into the Grasse river, and that of the southerly half by the same means into the Raquette river.

Provision has been made for a chemical precipitation disposal plant at each outlet whenever their installation may become necessary.

The present population of the village is, approximately, 1800, but on account of the location here of the power plant of the St. Lawrence power company's canal-the largest power plant in the United States except that at Niagara-it has been deemed expedient to plan the sewer system for a population of 30,000. The engineer's report follows:

REPORT

MASSENA, N. Y., September 12, 1899 To the Honorable the Board of Health of the State of New York: Gentlemen-I herewith submit plans for a system of sewerage for the village of Massena for your approval.

When the matter was first taken up with the village trustees, after carefully looking over the ground, it was decided to submit plans for a separate system as being the most advantageous and economical, the village having a natural drainage into the Grasse and Raquette rivers, which dispose of the surface water.

In designing the system it has been divided into three districts, designated on the plans as A, B and C.

District A, on the north bank of the Grasse river, has a population of approximately 500, and the main sewers are designed for an estimated population of 10,000. The outlet for this district is through a 12-inch pipe, and it discharges into the Grasse river below the upper dam.

District B, on the south bank of the Grasse river, has a population of approximately 1000, and the main sewers are designed for an estimated population of 12,000, for in this district, on account of the large population and more rapid growth, the outlet has been carried to a point below the lower dam, where it discharges into the Grasse river through an 18-inch pipe.

District C, on the north bank of the Raquette river, has a population of approximately 300, and the main sewers are designed for an estimated population of 8000. The outlet for this district is into the Raquette river through a 15-inch pipe.

No system has been designed for that section of the village situated south of the Raquette river, as there seems to be no immediate demand for sewers, it having a comparatively small population; and as it would call for a separate outlet, it did not seem necessary to include it in this plan.

Sewers have not been shown on certain proposed streets in Districts B and C, as there is some uncertainty regarding their final location.

All lateral sewers are designed for an estimated population of 30 to an acre, and all sewers to dispose of 30 cubic feet per person in 24 hours.

The sewers are intended for house sewage only, all roof and ground water being excluded.

Very truly yours

SAG HARBOR, N. Y.

Amended plans

Plans providing for a change of location of the outlet of the system from that shown on the plans originally approved by this Board were approved February 14, 1900, with the understanding that in case disposal works are later deemed necessary, the orig inal plan or another equally satisfactory to the State Board of Health will be demanded.

MOUNT VERNON, N. Y.

Change of plans

On February 14, 1900, plans were approved for a temporary change of the outlet sewer of the Vernon Park district so as to discharge the sewage into Eastchester creek, temporarily, by a shorter route than was originally planned and approved.

CANAJOHARIE, N. Y.

Separate sewer system

Plans for a separate sewer system and disposal works were approved by this Board February 14, 1900.

The plans provide for the purification of the sewage during the dry months by means of a septic tank. At other times, or when the flow of water in the Mohawk river is of sufficient volume
