New sanitary sewers and all extensions to sanitary sewers owned and operated by the Village shall be designed in accordance with the recommended standards for sewage works, as adopted by the Great Lakes-Upper Mississippi River Board of State Sanitary Engineers (Ten State Standards) and in strict conformance with all requirements of the NYSDEC. Plans and specifications shall be submitted to and written approval shall be obtained from the Superintendent, the County Health Department and the NYSDEC before initiating any construction. The design shall anticipate and allow for flows from all possible future extensions or developments within the immediate drainage area.
When a property owner, builder or developer proposes to construct sanitary sewers or extensions to sanitary sewers in an area proposed for subdivision, the plans, specifications and method of installation shall be subject to the approval of the Superintendent and the County Health Department, in accordance with § 135-22. Said property owner, builder or developer shall pay for the entire installation, including a proportionate share of the treatment plant, intercepting or truck sewers, pumping stations, force mains and all other Village expenses incidental thereto. Each street lateral shall be installed and inspected pursuant to Article VI and inspection fees shall be paid by the applicant prior to initiating construction. Design and installation of sewers shall be as specified in §§ 135-25 through 135-28 and in conformance with Paragraphs 3 through 6 of ASTM Specification C-12. The installation of the sewer shall be subject to periodic inspection by the Superintendent, at the Superintendent's discretion. The Superintendent shall determine whether the work is proceeding in accordance with the approved plans and specifications and whether the completed work will conform to the approved plans and specifications. The sewer, as constructed, must pass the infiltration test (or the exfiltration test, with prior approval), required in §§ 135-29 through 135-33, before any building lateral is connected thereto. The Superintendent shall be notified 30 days in advance of the start of any construction actions so that such inspection frequencies and procedures, as may be necessary or required, may be established. No new sanitary sewers will be accepted by the Village Board until such construction inspections have been made so as to assure the Village Board of compliance with this Part 1 and any amendments or additions thereto. The Superintendent shall report all findings of inspections and tests to the Village Board.
Plans, specifications and methods of installation shall conform to the requirements of this article. Components and materials of wastewater facilities not covered in this Part 1, such as pumping stations, lift stations or force mains shall be designed in accordance with § 135-22 and shall be clearly shown and detailed on the plans and specifications submitted for approval. When requested, the applicant shall submit to the superintendent and to the County Health Department all design calculations and other pertinent data to supplement review of the plans and specifications. Results of manufacturer's tests on each lot of pipe delivered to the job site shall be furnished, upon request.

U. 
The pipe shall be in straight alignment.
V. 
The remaining portion of the trench above the pipe embedment shall be backfilled in foot lifts which shall be firmly compacted. Compaction near/under roadways, driveways, sidewalks and other structures shall be to 95% of the maximum moisture-density relationship, as determined by ASTM Specification D-698, Method D.
W. 
Consideration shall be given to the disposal of groundwater which collects in the pipe bedding. This water will flow to a low point where it may collect and appear on the ground surface or follow along sewer laterals.
A. 
Manholes shall be placed where there is a change in slope or alignment and at intervals not exceeding 300 linear feet.
B. 
Manhole bases shall be constructed of 3,500 pounds per square inch (seven-day) concrete 12 inches thick or shall be precast bases properly bedded in the excavation. Field constructed bases shall be properly reinforced.
C. 
Manhole walls shall be constructed using precast minimum four-foot diameter manhole barrel sections and an eccentric top section, conforming to ASTM Specification C-478. All sections shall be cast solid, without lifting holes. Larger diameters may be required by the Superintendent for junction holes.
D. 
All joints between sections shall be sealed with an O-ring rubber gaskets meeting the same specifications as pipe joint gaskets.
E. 
All joints shall be sealed against infiltration and filled with mortar, both inside and outside, after the manhole barrel installation.
F. 
Aluminum steps, of drop-front design, shall be set in manhole walls.
G. 
All precast sections shall be produced at a plant which is approved by the NYSDOT for the manufacture of concrete pipe.
H. 
The elevation of the top section shall be such that the cover frame top elevation is 0.5 feet above the one-hundred-year flood elevation (in a field), 0.5 feet above a lawn elevation, or at finished road grade.
I. 
The manhole frame cover shall be heavy-duty cast iron.
(1) 
The cover shall be 24 inches in diameter. The minimum combined weight of the frame and the cover shall be 400 pounds. The mating surfaces shall be machined and painted with tar pitch varnish.
(2) 
Covers shall have "sanitary sewer" cast into them. Covers shall have two pick holes 180° apart. The pick holes shall be designed so that infiltration is prevented.
J. 
Benches shall be level and slope to the flow channel at about one inch per foot.
K. 
The minimum depth of the flow channel shall be 3/4 of the nominal diameter of the larger pipe. The channel shall have a steel trowel finish.
L. 
Manhole frames shall be set in a full bed of mortar with no less than two nor more than five courses of brick underneath to allow for later elevation adjustment.
M. 
Interior and exterior manhole walls and bottom of cover slabs shall be coated with an approved coating system.
A. 
All sanitary sewers or extensions to sanitary sewers, including manholes, shall satisfy requirements of a final infiltration test before they will be approved and wastewater flow permitted by the Village. The infiltration rate shall not exceed 100 gallons per 24 hours per mile per nominal diameter in inches. An exfiltration test may be substituted for the infiltration test; the same rate shall not be exceeded. The exfiltration test shall be performed by the applicant under the supervision of the Superintendent, who shall have the responsibility for making proper and accurate measurements required.
B. 
The exfiltration test consists of filling the pipe with water to provide a head of at least five feet above the top of the pipe or five feet above groundwater, whichever is higher, at the highest point under test, by the amount of water which must be added to maintain the original level. In this test, the test section must remain filled with water for at least 24 hours prior to taking any measurement. Exfiltration shall be measured by the drop of water level in a standpipe with closed bottom end, or in one of the sewer manholes serving the test section. When a standpipe and plug arrangement is used in the upper manhole in the test section, there shall be some positive method for releasing entrapped air prior to taking any measurements.
The test section shall be as ordered or as approved, but in no event longer than 1,000 feet. In the case of sewers laid on steep grades, the test length may be limited by the maximum allowable internal pressure on the pipe and joints at the lower end of the test section. For purposes of determining the leakage rate of the test section, manholes shall be considered as sections of forty-eight-inch diameter pipe, five feet long. The maximum allowable leakage rate for such a section is 4.5 gallons per 24 hours. If leakage exceeds the allowable rate, then necessary repairs or replacements shall be made and the section retested.
The test period during which the test measurements are taken shall not be less than two hours.
Prior to testing, the section shall be lamped. Any joint out of straight alignment shall be realigned.
A. 
In lieu of hydrostatic testing (exfiltration or infiltration), air testing may be employed. Low-pressure air tests shall conform to ASTM Specification C-828. All sections to be tested shall be cleaned and flushed and shall have been backfilled prior to testing. The air test shall be based on the time, measured in seconds, for the air pressure to drop from 3.5 pounds per square inch to 2.5 pounds per square inch. Acceptance is based on limits stated in ASTM Specification C-828. Before pressure is applied to the line, all connections shall be firmly plugged. Before the test period starts, the air shall be given sufficient time to cool to ambient temperature.
B. 
If the test section is below groundwater, the test pressure shall be increased an amount sufficient to compensate for groundwater hydrostatic pressure; however, the test pressure shall not exceed 10 pounds per square inch.
C. 
The test gauge shall have been recently calibrated and a copy of the calibration results shall be made available to the Superintendent prior to testing.
All sanitary sewers and extensions to sanitary sewers constructed at the applicant's expense, after final approval and acceptance by the Superintendent and concurrence by the Village Board, shall become the property of the Village and shall thereafter be operated and maintained by the Village. Said sewers, after their acceptance by the Village, shall be guaranteed against defects in materials or workmanship for one year, by the applicant. The guaranty shall be in such form and contain such provision as deemed necessary by the Village Board, secured by a surety bond or such other security as the Village Board may approve.
No property owner, builder or developer shall be issued a building permit for a new dwelling or structure requiring sanitary facilities unless a suitable and approved method of wastewater disposal conforming to this Part 1 is available. All housing construction or building development which takes place after this Part 1 is enacted shall provide for an approved system of sanitary sewers, unless the Village Board shall find, by resolution, that installation of such system of sanitary sewers cannot presently be accomplished in such instances where one single building lot is to be improved with a dwelling and the point of connection to said system of sanitary sewers is located more than 700 feet distant from the nearest lot line. No exception shall be made if any property is to be subdivided or if more than one dwelling is to be erected on a lot.
A. 
All contractors engaged in connecting house laterals with sanitary sewers who perform any work within the right-of-way of any highway shall file a bond in the amount of $5,000 with the Village Clerk to indemnify the Village against loss, cost, damage or expense sustained or recovered on account of any negligence, omission or act of the applicant for such a permit or any of his, their or its servants or agents arising or resulting directly or indirectly by reason of such permit or consent or of any act, construction or excavation done, made or permitted under authority of such permit or consent. All bonds shall contain a clause that permits given by the Village Board may be revoked at any time for just cause.
B. 
Before commencing work, the above contractor shall file with the Village Clerk insurance certificates for the following: public liability limited to $50,000 for injuries and including wrongful death to each person limited to $100,000 on account of each occurrence; and property damage for $100,000 for damages on account of any occurrence and $300,000 aggregate. The policies shall cover motor vehicle operations and the use of explosives and blasting. All insurance policies must provide for five days' notice to the Board before cancellation and must cover all liabilities of the Village Board and be in a satisfactory form approved by the Board.
C. 
Where it is necessary to enter upon or excavate within any right-of-way or any highway or cut any pavement, sidewalk or curbing, permission must be obtained from the Superintendent if a Village highway is involved, from the County Department of Public Works if a county highway is involved and the New York State Department of Transportation if a state highway is involved.
