Infrastructure and Utilities

Information

Saginaw Township operates and maintains several hundred miles of water mains and sewer lines.  Growth and density has traditionally followed the availability and/or required the installation of public utilities, in particular water and sanitary sewer.  As such, both are prevalent through the vast majority of the Township.  Public water is available throughout the Township and there are existing water mains along every street.  If water is not directly accessible to a particular parcel, it is available in close proximity.  There are only two primary roads that lack a public water main for any portion:  Center Road, south of Michigan Avenue to the River and Gratiot Road, west of Midland Road to the River.  Sanitary sewer is also generally available throughout the Township with the exception of most property in the northwestern portion of the Township, south of Tittabawassee Road, west of Midland Road and north of the Sawmill Subdivision.

The Department of Public Services (D.P.S.) maintains the potable water distribution system within the Township.  The distribution system is composed of approximately 235 miles of water main, 2400 water main valves, 2200 fire hydrants, and a 750,000 gallon elevated storage facility. 

Storm Water and Waste Water
Saginaw Charter Township has been managing storm water runoff under the existing ordinance since 1980 in an effort to reduce the risk of overloading the storm drainage systems located within the Township.  The Township initially adopted a storm water ordinance in 1980, and then, with the adoption of a formal storm water management plan, updated this ordinance in 1998.  The Township’s storm water management plan is implemented and operated by the Saginaw Charter Township Department of Community Development. The Department is responsible for the review of new development and redevelopment plans and for the installation and maintenance of measures within the Township to accomplish the plan. The Department works in conjunction with Township Administration, the County Public Works Commissioner, the County Road Commission, architectural and engineering consultants, landowners, and developers within the Township.

The Township's wastewater collection system and treatment facilities are maintained by employees of the Department of Public Services.  The Saginaw Charter Township wastewater collection and treatment system is composed of the following facilities: 

• *4.8 to 14.6 million gallon day (MGD) extended aeration wastewater treatment facility
• *6.0 million gallon (MG) combined sewer retention basin
• *landfill leachate treatment facility, and
• *Nine (9) wastewater collection pumping facilities. 

The wastewater collection system in Saginaw Charter Township is divided into four districts:  Northeast Sewer District, Weiss St. District, Southwest District, and Center Road District.  The wastewater collected from the Northeast and Weiss St. Districts is processed and treated at the City of Saginaw Wastewater Treatment Facility located at 2406 Veterans Memorial Parkway and discharged into the Saginaw River.  The wastewater collected from the Southwest and Center Rd. Districts is processed and treated at the Saginaw Charter Township Wastewater Treatment facility located at 5790 W. Michigan and then discharged into the Tittabawassee River.  There are nine pumping facilities (lift stations) that are strategically located throughout the four districts to aid in the collection process.  In addition, the Center Rd. District has a 6.0 MG Combined Sewer Retention Facility that is utilized as a storage and treatment facility during above normal precipitation periods.

The Saginaw Charter Township Wastewater Treatment Plant purifies wastewater from the Southwest and Center Road Districts in Saginaw Township as well as from Thomas Township.  Wastewater from Thomas Township is pumped to the site where it is metered and introduced into the process.  Wastewater from Saginaw Township arrives at the plant site in gravity sewers and is merged with Thomas Township's wastewater.  The combined wastewater then receives primary treatment.  Chlorine is also added at this point for odor control.  Primary treatment is provided by two mechanically cleaned bar screens and two aerated grit tanks.  Screenings and grit materials are disposed of into a dumpster and hauled to a landfill.  Primary effluent treatment is accomplished in two circular primary settling tanks.  Sedimentation is pumped from the settling tanks into two high rate anaerobic digesters.  Secondary treatment consists of extended aeration with activated sludge in two oxidation ditches.  Ferric Chloride is then added to the waste stream for the removal of phosphorous, followed by the addition of polymers to aid in settling. 

Secondary clarification occurs in two circular final settling tanks.  Sedimentation from these two tanks is returned to the oxidation ditches and transferred as needed to another process for additional settling and disposal.  The clear effluent that is discharged from the final settling tanks then enters the last purification stage of the treatment process.  Chlorination/Disinfection is applied using chlorine gas and jet mixing.  The treated effluent is then dechlorinated and further polished in a 6.1 million gallon polishing pond.  Sodium Thiosulfate is also added to aid in the dechlorination process prior to the discharge to the Tittabawassee River.  Sludge digestion and decomposition is a natural biological process that occurs throughout all phases of the wastewater treatment process.  Mechanically controlled environments in the anaerobic digesters, oxidation ditches, and sludge holding tanks enhance microorganism activity and sludge decomposition.  The biosolids that are generated from the sludge digestion process are then hauled to agricultural fields and land applied.
