Long-Term Capital Improvement Program
In 2004, the Township developed a long-term capital
improvement program for pipe replacement within the older
subdivision areas that contain less than six-inch diameter
water mains. The areas identified for replacement were
evaluated based upon both size and repair criteria. There are
over 39 miles of this piping that existed in the older water
systems built before the Township connected to the City of
Detroit’s water supply system in 1964.
Benefits of this program: Improves water volume,
reliability of fire hydrants, and water supply system
longevity, as well as reduces maintenance and repair costs.
Promotes compliance with the Safe
Drinking Water Act standards.
Sanitary Sewer Rehabilitation Program
Since 2000, Bloomfield Township has been implementing a
program to rehabilitate the public sanitary sewer system. The
purpose of the program is to improve reliability and reduce
excess inflow. As a result, we can eliminate sewer overflows
and reduce cost for treatment of non-waste water entering the
The program varies throughout the Township based upon age
of the system and findings from extensive field
investigations. Field investigations may include in-line sewer
flow metering, manhole inspections, sanitary sewer televising,
smoke testing and visual observation of downspouts and sump
pump connections. Sewer rehabilitation work, performed by a
Township contractor, consists of either open-cut excavated
repairs or trenchless technology such as internal joint
grouting and internal pipe liners.
Private house leads may allow inflow into the system
through open joints, cracks or openings created by tree roots.
Also, footing drains, roof downspouts, and sump pump
connections to the sanitary sewer have been found to be a
primary source of excess flows within the Township.
Homeowners can also help reduce inflow into the public sewer
system by verifying that their house leads are properly
functioning and connected to the appropriate sewer.
Benefits of this program: Reduces sewage volume for
treatment charges; reduces sewer back-ups, overflows, and
maintenance cost; improves sewer system longevity; and
promotes compliance with the Clean Water Act.
