Warren Water Recovery Facility
The City’s Water Recovery Facility was originally designed in 1957, since that time it has undergone considerable changes and become one of the leaders in wastewater treatment in the state. The City now has a state of the art treatment plant that has a design capacity of 50 MGD per day and can handle a peak flow during a wet weather event of 100 MGD. The City of Warren Water Recovery Facility regularly treats 22 MGD of wastewater. The average resident creates 350 gallons a day of wastewater. The City’s plant treats that water and the water used by our industries to produce a quality effluent to the waters of the state.
At the City of Warren our IPP staff is committed to identifying and eliminating pollutants from our water ways. One new emerging pollutant that our staff is currently dealing with is called PFAS (Polyfluoroalkyl Substances). The City of Warren is currently in full compliance with the State of Michigan’s discharge levels. For more information please use links below.

We encourage our residents to take a tour of our Water Recovery Facility. This tour is offered at no cost. This is a great way to learn about the water treatment process from start to finish. If you are interested in a tour please contact us at 586-264-2530.
The City of Warren is currently constructing a 21 MG Detention basin at 14200 Stephens. This basin is being constructed to correct the deficiencies in the sewer collection system. These deficiencies in the sewer system contribute to sanitary sewer overflows as well as the occasional basement backups. For more information click on information provided below.
What You Need to Know About Clean Water
Whether it’s keeping fats, oils, and grease out of drains, supporting upgrades to local wastewater facilities, putting trash in the trash can instead of the toilet, or even picking up after your pet, everyone can play an important part in protecting the world’s water resources.
These Public FAQs offer information on topics ranging from wastewater treatment to water quality protection.
Many of these water quality topics are also covered in WEF’s inexpensive series of brochures and bill stuffers, which can be purchased for distribution at environmental fairs and other public venues. Shop WEF to learn more.
When Did Wastewater Treatment Begin?
Treatment of wastewater is a relatively modern practice. While sewers were common in ancient Rome to remove foul-smelling water, it was not until the 19th Century that large cities began to reduce the amount of pollutants in the wastewater they were discharging to the environment. Since that time, the practice of wastewater collection and treatment has undergone substantial engineering improvements, and many state and federal regulations have been enacted.
How Does Wastewater Treatment Work?
Most homes, businesses, and institutions are connected to a sewer system that conveys their wastewater to a public wastewater treatment plant. Sanitary sewer systems carry only domestic and industrial wastewater, while combined sewer systems also carry stormwater runoff. At the plant, the wastewater is cleaned and returned to the environment to be used over and over again.
Wastewater flows by gravity with occasional help from pumps until it reaches the treatment plant. What happens in a wastewater treatment plant is essentially the same as what occurs naturally in a lake or stream. The function of a wastewater treatment plant is to speed up the process by which water is cleaned naturally. Treatment plants are operated 24 hours a day by a treatment team that is committed to protecting public health and the environment.
How Is Wastewater Treated?
Wastewater is typically treated through a series of five major steps followed by processes to reuse or to dispose of the remaining products. This treatment requires an intricate balance of physical, biological, and chemical processes. They include:
• Preliminary Treatment includes screening to remove large objects (such as sticks, rags, leaves, and trash) and the settling of grit (heavy, sandy, abrasive matter). The material is collected and discarded, and the remaining flow moves on to primary treatment.
• Primary Treatment involves the reduction of the wastewater flow to remove easily settleable and floatable solids using primary tanks known as clarifiers. Solids removed from this process are often sent to the solids handling portion of the plant.
• Secondary Treatment is designed to grow naturally occurring microorganisms to digest organic material, sometimes remove nutrients, and then to settle to the bottom of a secondary sedimentation basin. After secondary treatment, 85% to 90% of solids have been removed from the wastewater.
• Tertiary (or Advanced) Treatment is used to improve the quality of the water even more, especially if the plant’s permit requires more stringent effluent limits. Usually, this entails lower effluent solids and nutrients, such as nitrogen and phosphorus levels.
• Disinfection destroys pathogenic organisms in the effluent before it discharged into the receiving water body to help protect the public from exposure to pathogens. Alternatives for disinfection include chlorination followed by dechlorination, exposure to ultraviolet light, and the infusion of ozone.
• Solids Handling involves the treatment of the solids removed from the water treatment processes for beneficial use or to be made acceptable for landfills.
What Happens to the Products of Wastewater Treatment?
The two main products of the wastewater treatment process are clean water and the collected solids that, after treatment, are known as biosolids. Some communities further treat clean water for recycling so it can be used in ways such as golf course and landscape irrigation, and even groundwater recharge programs. Biosolids can be reused in a variety of ways: applied as a fertilizer/soil conditioner (for agricultural, land reclamation, or horticultural use), burned to produce energy, or used as a component of other useful products.
What Can Consumers Do?
A community’s quality of life and economic vitality depend on wastewater systems that work. Consumers can make a difference by supporting initiatives to protect and improve the nation’s aging clean water infrastructure. (Water Is Life link.) And they can learn how to dispose of household wastes properly so that only human waste and water enter the sewer system. (Link to household waste chart.)
