(2)
The fee as determined by the Drain Commissioner for
connection permits shall be $150 which is to cover the cost of the
inspection of the tap.
(3)

the supervision of an inspector from the Drain Commissioner's office
in accordance with approved plans of said connection.
(4)
A minimum of 24 hours' notice (excluding Saturday,
Sunday, and holidays) must be given prior to tap to enable this office
to arrange for inspection.
(5)
Requests for inspection shall be directed to the technician
charged with the responsibility of permit issuance (858-0978).

owner or contractor from the Oakland County Drain Commissioner's Office.
Said connection permit shall show the location of the work, the extent
of the work, information regarding the contractor, the owner and the
engineer, the scheduled date of infiltration test and any other pertinent
information as shall be determined necessary by the Oakland County
Drain Commissioner. A fee shall be charged for said permit to cover
the cost of inspection of the connection and system connected.
(b)
All sewer systems shall be subjected to infiltration,

have a minimum diameter of 3 1/2 inches and a range of 0-10 PSIG.
The gauge shall have minimum divisions of 0.10 PSIG and an accuracy
of plus/minus 0.04 PSIG.
[b]
The sewer shall be pressurized to four PSIG
greater than the greatest back pressure caused by groundwater over
the top of the sewer pipe. At least two minutes shall be allowed for
the air pressure to stabilize between 3.5 and four PSIG. If necessary,
air shall be added to the sewer to maintain a pressure of 3.5 PSIG
or greater.
[c]
After the stabilization period, the air supply
control valve shall be closed so that no more air will enter the sewer.
The sewer air pressure shall be noted and timing for the test begun.
The test shall not begin if the air pressure is less than 3.5 PSIG,
or such other pressure as is necessary to compensate for groundwater
level.
[d]
The time required for the air pressure to decrease
1.0 PSIG during the test shall not be less than the time shown in
the Oakland County Drain Commissioner's Air Test Tables.
[e]
Manholes on sewers to be subjected to air tests
shall be equipped with a one-half-inch-diameter galvanized capped
pipe nipple extending through the manhole, three inches into the manhole
wall and at an elevation equal to the top of the sewer pipe. Prior
to the air test, the groundwater elevation shall be determined by
blowing air through the pipe nipple to clear it and then connecting
a clear plastic tube to the pipe nipple. The tube shall be suspended
vertically in the manhole and the groundwater elevation determined
by observing the water level in the tube. The air test pressure shall
be adjusted to compensate for the maximum groundwater level above
the top of the sewer pipe to be tested. After all tests are performed
and the sewer is ready for final acceptance, the pipe nipple shall
be plugged in an acceptable manner,
(c)
If a sewer fails to pass any of the previously
described tests, the contractor shall determine the location of the
leaks, repair them and retest the sewer. The tests shall be repeated
until satisfactory results are obtained.
(d)
All visible leaks and cracks shall be repaired
regardless of test results.
(2)
Stormwater and groundwater control.
(a)
Yard drains, patio drains, catch basins, downspouts,
weep tile, perimeter and footing drains or any other structure used
for the collection and conveyance of stormwater and/or groundwater
shall not be permitted to discharge into any sanitary sewer connected
directly or indirectly to the county system, except as provided below.
(b)
Perimeter and footing drains installed after
August 22, 2013, shall either be connected to an existing public combined
or separate storm sewer, or shall discharge onto grade at least 15
feet from the nearest property line.
[Amended 8-12-2013 by Ord. No. 2013-13]
(c)
The crock to iron joint shall be sealed by approved
flexible adaptor fittings such as those manufactured by Fernco Joint
Sealer Company, or as approved by the Oakland County Drain Commissioner's
Office. The iron pipe inside the building shall be plugged and leaded
and remain plugged and watertight until such time as the plumbing
is carried on to the first floor, the basement backfilled and the
roof is on the building, thereby providing that no water from the
excavated basement will enter the sanitary sewer.
(3)
Building sewers.
(a)
House connection sewer from lateral sewer in
the street or easement five feet from house shall be:
[1]
Six-inch diameter extra strength vitrified sewer
pipe, manufactured in accordance with current NCPI Designation ER
4-67 Standards, or equal, with Drain Commissioner approved premium
joint; or
[2]
Six-inch diameter ABS plastic solid wall sewer
pipe conforming to ASTM designation D-2751 SDR 35 or 23.5; or
[3]
Six-inch diameter PVC plastic solid wall sewer
pipe conforming to ASTM designation ASTM D-3034 SDR 35 or ASTM D-2665
Schedule 40.
[4]
Other pipes and joints as may be approved by
the Oakland County Drain Commissioner.
(b)
House connection sewers should be six-inch minimum
diameter; however, four-inch pipe of comparable strength and joint
material may be used if permitted by the local unit of government.
All joints shall be tight and, when tested for infiltration, shall
not exceed 500 US gallons per inch of diameter, per mile, per 24 hours.
(c)
The crock to iron joint shall be sealed by an
approved bituminous filler, enclosed in concrete to provide a watertight
seal. The iron pipe inside the building shall be plugged and leaded
and remain plugged and watertight until such time as the plumbing
is carried on to the first floor, thereby providing that no water
from the excavated basement will enter the sanitary sewer.
(d)
The municipality shall issue tap permits for
each structure that is connected into the SOCSDS and be responsible
to see that the above specifications pertinent to materials and installations
are followed.
(4)
The SOCSDS, through its agent, the Drain Commissioner,
shall, at his option, be permitted to set up and operate flow metering
equipment to gauge sanitary flow, either on a temporary or permanent
basis, in any sanitary sewer lying within the said separated areas.
(5)
Plans and specifications covering the construction
of all new sewers, both combined and sanitary (separate), lying within
the SOCSDS service area shall be submitted to the office of the Oakland
County Drain Commissioner for review and approval prior to construction.
(6)
The quality of domestic and industrial waste outletted
into the SOCSDS facilities shall conform to the current City of Detroit
Ordinance pertinent to domestic and industrial wastes. It is the contractual
obligation of the municipality, reference Section 16 of contract with
county, to use SOCSDS facilities to enforce these standards.
(7)
No requirements of the SOCSDS or permits issued hereunder
by said system through its agent, the Oakland County Drain Commissioner,
shall relieve the property owner of complying with all the rules and
regulations of the local unit of government, wherein such property
is located, where such are not in conflict with requirements of the
SOCSDS.
(8)
All sewer construction shall comply with the general
specifications of the Oakland County Drain Commissioner; copies of
said specifications may be obtained from the office of the Drain Commissioner.[2]
