DORSEY STREET INTERCEPTOR Carry the Maple street main sewer along the left bank of the Saranac river to the head of the Dorsey street interceptor, entering it at the foot-bridge. Change the sizes of the Dorsey street interceptor, making them as follows: From the center of Broadway to the foot-bridge, 15 inches; from the foot-bridge to the interseection of Maple and Lake streets, 12 inches in diameter. Change the grades on the Dorsey street interceptor to correspond to those shown on the accompanying profile thereof. MAPLE STREET MAIN SEWER Change the grade of the Maple street main sewer to correspond with the grades shown on the accompanying profile of the Dorsey street interceptor, and use a rate of fall on Maple street of .20 feet per 100 feet on Maple street from Lake street to the foot of the interceptor on the west bank of Lake Flower. The changed grade elevations will be as follows: Maple street and Lake street, 1457 feet; Maple at foot of interceptor on west bank of Lake Flower, 1460.6 feet. To carry out the idea of keeping the interceptor on the west side of Lake Flower as high as is practicable in order to avoid expensive work below the water level of the lake, the same rate of grade should be used on that interceptor to the third manhole east of Maple street continued. At that manhole a sewage lift should be built to raise the sewage collected from the streets in that vicinity up to the grade of the interceptor, using the sewage itself as power. SPECIFICATIONS The specifications accompanying the general sewer plan, a copy of which is hereto attached, shall apply to the proposed changes. SARANAC LAKE, N. Y. Description of a sewer to be built in Trestle street, Saranac Lake, N. Y., referred to in the recommendation of the board of health of said village, dated November 8, 1899, and in the rec ommendation of the board of trustees of said village, and in recommendation of the board of sewer and water commissioners of said village dated November 17, 1899, and presented to the State Board of Health February 1, 1900. Beginning at the intersection of Trestle street and the Saranac river, thence north on said street a distance of 450 feet to a flush tank. The sewer is to be six inches in diameter and to be laid on the grades shown on the general sewer plan for said village. FISHKILL LANDING, N. Y. Separate sewer system Plans providing for a separate sewer system for the entire village were approved by this Board April 27, 1900. The sewage from the main system is to be collected by gravity at the foot of Main street, whence it will flow under the waters of the Hudson river 1300 feet to the channel bank. A small portion of the southerly part of the town will be sewered directly into the Hudson river through the Denning avenue outlet, which is about 4200 feet south of the Main street outlet. The plans contemplate the possibility of a disposal plant at some future time, to be located at a point on the Main street outlet at the river shore. The engineer's report follows: SEWERS OF FISHKILL LANDING, N. Y. ENGINEER'S REPORT, TOGETHER WITH ESTIMATE OF COST, CONTRACT, SPECIFICATIONS, ETC. To the Honorable President and Board of Trustees of the Village Fishkill Landing, N. Y.: Gentlemen-I herewith transmit plans and specifications of a sewerage system for your town. This system contemplates the removal of household sewage and to some extent the subsoil water. It does not provide for nor contemplate the admission of any storm water. Several of your members have expressed their desire that some provision be made for the removal of storm water in certain localities. The localities where the storm water has been found troublesome can be drained more economically by an entirely separate system. The topographical conditions existing in your town divide it into two general slopes. One toward the west, the Hudson river slope; the other toward the east, toward the Matteawan creek. However desirable the removal of the storm water may be, still as a menace to health and soil pollution it is not commensurate with the sewage from the household. Having a limited population and assessed valuation I fully appreciate your determination to practice the most rigid economy. Hence one of the first requisites is to eliminate the idea of an extensive system of storm-water sewers, which seldom need be coextensive with those required for the removal of house sewage. On the western slope at the present time there is not a pressing need for the removal of the storm water, except possibly on Beekman street and Main street. A storm-water sewer on Beekman street need not be expensive, and the present outlet near the railroad bridge can be utilized, which would not be the case if the wastes from the household were admitted to the sewer. Main street has a cement sewer of from 12 inches to 20 inches in diameter which is now used as a partial combined sewer. With a small expenditure for inlets and the elimination of the house sewage, this sewer, while of limited area, could neverthe less be made to do good service. On the eastern slope, which has a much less rate of inclination, there has been considerable annoyance from storm water. This storm water, however, can be conducted by several short sewers into what is called the ditch, a small stream tributary to the Matteawan creek, much more economically than enlarging the long trunk line sewer on South Chestnut street, West Center street, Newburgh avenue, River street and Main street oulet sufficiently to carry off the storm water from the extended area. Again, in case at some future time it became necessary for the river towns to treat the sewage before its admission into the river, it could be done much more economically with the storm water excluded. Hence from both sanitary and economic conditions it has ap peared advisable to limit the plans to a separate system, leaving the storm water for an after consideration. As to scope, these plans make provision for the entire territory within the limits of the corporation, consisting of approximately 780 acres, except a small area at the extreme north and south. These sections are open country, with no immediate prospect of becoming transformed into town property. Should they, however, become thickly settled in the future, both are on the western slope, and each will require a separate outlet not conflicting in any way with the present system. It is not likely that you will desire to construct all the sewers laid out on the plan at the present time. It is quite essential, however, that the plan and estimate be made for the whole village in order that any part you may elect to construct now or at any future time may be constructed in conformity to lines laid down in a general plan. Elsewhere you will find a tabulated statement of the sizes, depth and grade of the sewer, with the velocity and discharge for different depths of flow, together with an estimated tributary population which the sewer will amply provide for, still leaving a large margin for safety, ventilation, etc. We note here that the present population is approximately 5000. This sewer, when running half full, will provide for a population five times as great. A brief description of the main system is as follows: The outlet is at the foot of Main street, extending 1300 feet to the channel of the river. At the intersection of Main and River streets the two main branches of the system are brought together. The northerly or Main street branch provides in general for all the territory north of Main street and west of Cross street, together with a small area on South avenue. The southern or Newburgh avenue branch provides for the remaining territory on the western slope, except the small southern section provided for by Denning avenue outlet. The Newburgh avenue sewer runs easterly on Newburgh ave. nue nearly to South avenue; thence along private lands to West Center street; thence easterly on West Center street or its probable extension, cutting through the divide between the eastern and western slopes to South Chestnut street; thence northerly on South Chestnut street to Main street, continuing northerly on North Chestnut street to Church street; thence westerly on Church street to North Cedar street; thence northerly on North Cedar street to Verplanck avenue. This line after reaching South Chestnut street is entirely to the east of the village and almost exactly follows the corporation line. It will intercept or provide an outlet for every sewer which may become necessary on this slope. As before stated, these two branches (Main street and Newburgh avenue, with the small southern section having an outlet at the foot of Denning avenue and having tributary only to Hudson, Smith and John streets, with provision also of a part of the south side of Newburgh avenue) will provide for the entire territory within the corporate limits, with the exception of the extreme north and south. There are already laid sewers on Main street from the river to Cottage place, also sewers (12-inch) on Willow street from Main to Oak street, and the entire length of Cottage place. The Main street sewer can be utilized as a storm-water sewer exclusively. The Willow and Cottage place sewers have been incorporated in this system. An automatic flush tank is placed at the north end of Cottage place sewer. On Willow street the sewer is extended to Verplanck avenue. |
