Another important part of our city services is the management of the Class III Municipal Wastewater Treatment Facility, which is integral to protecting the health and well being of the community and downstream users.
The facility consists of two treatment plants that provide preliminary, primary, secondary and disinfection—at two sites. The overall design flow rate is 4.5 MGD with a peak design flow rate of 9.0 MGD.
(located on the west side of Cedar Creek) has a design flow rate of 2.5 MGD and a peak design flow rate of 4.0 MGD.
(located on the east side of Cedar Creek) has a design flow rate of 2.0 MGD and a peak design flow rate of 5.0 MDG. Tertiary treatment of the combined secondary wastewater effluent and sludge stabilization is provided for the combined sludge at the Plant #2 site.
Important environmental operations occur at these plant facilities. To better understand the types of treatment conducted at these plants, as well as how the Water Pollution Control Laboratory monitors plant discharges and performs process control testing, download these helpful community resources:
The Bio-Solids Division of Water Pollution Control houses perhaps the fastest growing program of the department: N-Viro Soil™. This innovative technology recycles and reuses the sludge by-product generated at the treatment facility.
The addition of the N-Viro Soil™ process has allowed us to discontinue a costly and time-consuming land application program and recycle wastewater sludge and other waste streams rich in organic matter into a safe, valuable product that can be beneficially reused. Most often used as fill dirt for city development and redevelopment projects, this recycled organic matter is an ecologically sound alternative to regular soil. Not only does it respond better to the environment because it contains fertilizer and absorbs water and other nutrients more fully, but it also saves taxpayer dollars because it requires less to help support plant growth.
This program has been effective in reducing pollutant discharge from combined sewer overflows and increasing the overall efficiency of the collection system. Specifically, the program oversees the:
After a heavy rain or snow, water either soaks into the ground or it flows over land and ends up in rivers and lakes such as Cedar Creek. When the latter occurs – called storm water runoff – it can take with it a lot of pollutants. While this is very natural process in urban areas, it causes very unnatural effects that negatively impact the quality of life we've come to value in Auburn. Specifically, storm water runoff:
To preserve our water table and water quality, the city's Storm Water Quality Management Program has several measures in place to ensure proper storm water management that ultimately protects public health, improves water quality, conserves resources and manages risk. Efforts include the Municipal Separate Storm Sewer System (MS4), a system of pipes and ditches for conveying storm water, as well as programs to address storm water control measures required by the United States Environmental Protection Agency's Clean Water Act and Indiana's Rule 13.
Effective storm water management requires active community involvement if it is to be successful over the long term. This support will help maintain our environment and minimize the amount of taxpayer money needed for processing and cleanup of water.
There are a number of ways both residents and businesses can easily support our storm water control efforts:
There are three city ordinances that specifically address storm water control. It’s important to familiarize yourself with these to ensure you are acting within the municipal laws of Auburn.
