Sanitary Sewers
In areas where sanitary sewer systems are operated and maintained by
the Oakland County Department of Public Works, final acceptance of the
system must be rendered by the Oakland County Department of Public Works
and the City of Farmington Hills before the system can be used for the
service intended.
One item required for final acceptance shall be the submission of
as-built plans to the City of Farmington Hills by the design engineer.
As-built plans for the sanitary sewer system shall be defined as and
contain the following information:
As-built sanitary sewer system plans shall indicate the offset of
sanitary sewers from property lines and shall include, but not be
limited to length of sewer, invert elevation, rim elevation,
percentage of grade, manhole location, sewer material and joints
used. An as-built profile drawing must also be provided for all
sanitary sewer systems.
Locations shall be shown on the plans with an accuracy of +
one (1) foot. In addition, the location of all building service
leads must be indicated from the downstream manhole. The length of
the lead and any riser information must also be indicated.
As-built sanitary sewer plans shall list the as-built quantities
and the type, brand name and lengths of pipe used.
The City of Farmington Hills and the Oakland County Drain
Commissioner no longer accept record mylars. Digital copies of the
plans in TIFF image files, burned onto a CD/DVD, must be submitted
instead. The project engineer should submit three (3) copies of the
CD/DVD, and two (2) sets of prints, signed and sealed, to our office
for archives. A cover letter, signed and sealed by the registered
professional who prepared the drawings, must be submitted indicating
that the plans on the CD/DVD are the final as-built plans for the
project.
Detention System
Upon completion of construction and prior to the final approval for
the Certificate of Occupancy, as-built plans must be submitted for
approval to the City of Farmington Hills by the design engineer.
As-built plans for the detention system shall be defined as and contain
the following information:
As-built plans of the retention system must include as-built
grade contours, with adequate spot elevations to substantiate these
contours. The high water and freeboard elevation and contour lines
must be clearly indicated. The side slopes of the pond also must be
clearly indicated. Also, as-built volumetric calculations must be
shown to verify that this system was built as designed and approved
by the City of Farmington Hills.

Storm Sewer
Upon completion of construction and prior to final approval of the
storm facilities, as-built plans must be submitted to the City of
Farmington Hills by the design engineer. As-built plans for the storm
system shall be defined as and contain the following information:
As-built storm system plans shall indicate the offset of storm
sewers from the property lines and shall include, but not be
limited to length of sewer, invert elevation, rim elevation,
percentage of grade, manhole location, sewer material and joints
used. An as-built profile drawing must also be provided for all
public storm sewer systems and private systems on sites larger than
one acre.
Locations shall be shown on the plans with an accuracy of +
one (1) foot.
As-built storm sewer plans shall list the as-built quantities and
the type, brand name and lengths of pipe used.

Water Systems
In areas where water systems are operated and maintained by the
Oakland County Department of Public Works, final acceptance of the
system must be rendered by the Oakland County Department of Public Works
and the City of Farmington Hills before the system can be used for the
service intended.
One item required for final acceptance shall be the submission of
as-built plans to the City of Farmington Hills by the design engineer.
As-built plans for water main shall be defined as and contain the
following information:
As-built water system plans shall indicate the offset of water
mains from property lines and shall locate gate valve wells,
hydrants and all water system appurtenances from the nearest
property corner. An as-built profile drawing must also be
provided for all watermains 16" in diameter or larger. Locations
shall be shown on the plans with an accuracy of + one (1)
foot. In addition, all underground appurtenances, such as gate valve
wells, meter pits, pressure reducing valve pits, etc., shall be
located from the nearest hydrant that is connected to the same water
main as the appurtenances. Locations shall be shown on the plans
with an accuracy of + one (1) foot.
As-built water system plans shall list the as-built quantities
and the type, brand name and lengths of pipe used. Hydrants, gate
valves, etc., shall also be listed showing their type, brand name,
and quantity. The location, size, manufacturer and model number of
every restrained joint shall be noted.
