Long-Term Capital Improvement Program

Long-Term Capital Improvement Program The Township has 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.

The long-term capital improvement program will be multi-phased over several years. Water main replacements will be prioritized based upon the ranking of the areas by the most frequent repair history. Each phase consists of multiple projects that will be grouped into separate project areas to be constructed over several years. The first phase has been completed in the Hickory Heights Subdivision located west of Adams and north of Wattles. Construction for the next phase of the project is expected to begin Summer 2008.

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 system.

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.
