New sanitary sewers and all extensions to sanitary
sewers owned and maintained by the Village Utilities Commission shall
be properly designed in accordance with the Recommended Standards
for Sewage Works, as adopted by the Great Lakes - Upper Mississippi
River Board of State Sanitary Engineers and in strict conformance
with all requirements of the New York State Department of Environmental
Conservation. Plans and specifications shall be submitted to and approval
obtained from the Engineer and New York State Department of Environmental
Conservation before construction may proceed. The design of sewers
shall anticipate and allow for flows from all possible future extensions
or developments within the immediate drainage area, being compatible
with the Master Sewerage Plan adopted by the Village.
[Amended 2-12-1991 by L.L. No. 1-1991]
A. All gravity sanitary sewers, extensions to sanitary
sewers, manholes, service connections or sewer laterals shall be tested
for leakage and shall satisfy requirements of a final exfiltration
(or leakage) test before they shall be approved and wastewater flow
permitted by the Commission. The labor, testing materials and equipment
for the exfiltration test required herein shall be provided and performed
by the property owner, builder or developer under the supervision
of the Engineer or his designated representative, who shall have the
responsibility for making the proper and accurate measurements required.
B. This test consists of filling the pipe with water
to a line or mark to provide a head of at least five feet above the
top of the sewer pipe or five feet above groundwater, whichever is
higher, at the highest point of the pipeline under test, and then
determining the loss of water from the pipeline by measuring the amount
which must be added to regain the original water level in the standpipe.
In this test the line must remain filled with water for at least 24
hours prior to taking the initial measurement of water level. The
test period for taking measurements shall not be less than two hours.
Total leakage of any section tested shall not exceed the rate of 100
gallons per mile of pipe per 24 hours per inch of nominal pipe diameter.
This is roughly equivalent to approximately 2.424 ounces per linear
foot of pipe per inch pipe diameter per day or 0.202 ounces (six milliliters)
per linear foot of pipe per inch pipe diameter per two-hour period.
C. Exfiltration shall be measured by the drop of the
water level in a standpipe with the lower ends of the sewer pipeline
closed, or in one of the sewer manholes for convenient measuring.
When the level of the groundwater table is of such height that the
manholes cannot be used for convenient measuring or if the vertical
distance between the top of the pipe and the manhole rim is less than
five feet, the pipeline shall be tested separately from the manholes
utilizing the standpipe method, including plugs, hoses, etc., to establish
the required head of water. Manholes shall then be examined for visible
leakage due to infiltration of groundwater, and such leaks shall be
plugged to the Engineer's satisfaction.
D. Should the test results be unsatisfactory, the owner,
builder or developer shall make all necessary repairs or replacements
and shall repeat the final leakage test(s) until the minimum leakage
requirements are met. For purposes of determining the maximum allowable
leakage, manholes are considered as sections of forty-eight-inch or
sixty-inch diameter pipe, depending upon the type of manhole included
in the test. The equivalent leakage allowance shall be 4.5 gallons
per manhole per 24 hours for forty-eight-inch diameter manholes, and
shall be 5.7 gallons per manhole per 24 hours for sixty-inch diameter
manholes.
All sanitary sewers and extensions to sanitary
sewers constructed at the property owner's, builder's or developer's
expense, after final approval and acceptance by the Engineer, shall
become the property of the Village and shall thereafter be maintained
by the Commission. Said sewers, after their acceptance by the Village,
shall be guaranteed against defects in materials or workmanship for
one year by the builder or developer. The guaranty shall be in such
form and contain such provisions as required by the Village, secured
by a surety bond or such other security as the Village 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 disposal
of wastewater is proposed and approved by the Village. All new housing
or building developments shall be provided with an approved system
of sanitary sewers.
Any person constructing or causing to be constructed
sewerage works (or any part thereof) or private wastewater disposal
facilities must present to the Clerk a certificate of insurance showing
suitable liability insurance before a permit will be issued for construction
of the same, said certificate to be written for the benefit of the
Village and to hold the Village harmless for any damages and claims
which may arise as a result of construction of said facilities.
