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 Water Resources
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.
