- Brad Talley (765) 807-1800
"2006 Collection System Award for Large Facility" was awarded to the City of Lafayette Water Pollution Control Dept. by the Indiana Water Environment Association. Awarded for innovative practices of maintaining the City's Collection System.
"Best Operated Wastewater Treatment Plant for Secondary Large in Region 5" was the title awarded to the City of Lafayette's Wastewater Treatment Plant by the U.S. EPA in 1995. The Administrators and employees of the Wastewater Treatment Plant, along with the Citizens of Lafayette, strive to address issues of health and environment.
* Design Capacity: 26 Million Gallons/Day (52 Million Gallons/Day Peak)
* Average Daily Flow: 16.9 Million Gallons/Day
* Usage fee per 1000 gallons to treat: 3.27
* Primary Treatment Facility upgrade in 2004
* Secondary Treatment Facility upgrade in 2004
Waste arrives at the treatment plant by way of an interceptor sewer, and with the help of Lift Stations. There are approximately 465.75 miles of combined sanitary and storm sewers. 25 Lift Stations, placed throughout the City, with a continuously monitored alarm system, keep the flow moving in order to complete the journey to the treatment plant. The sewers, Lift Stations, and all equipment involved, require regular maintenance.

Waste is treated at the Plant in a similar manner to that which occurs in nature. The objective in preliminary treatment is to remove the large debris, sand, and grit. During primary treatment, we remove a large percentage of the floatable and settleable material by physical methods. With secondary treatment we remove, and convert , biologically, contaminants remaining in the wastewater. The flow is then treated with chlorine to disinfect our effluent prior to discharge to the Wabash River.
During primary and secondary treatment, the removed solids (biosolids) are further processed by anaerobic digestion and prepared for land application. After a period of 15 - 30 days in the digester, the biosolids are forwarded to holding tanks and await land application.

An average of 16.9 Million Gallons per day of wastewater causes the generation of approximately 10 million gallons of biosolids. This biosolid material is applied to agricultural land to be used as a fertilizer supplement.
Currently the Land Application Program utilizes approximately 5,000 acres of agricultural land. These acres belong to 25 different landowners. The biosolid material is transported by tanker truck to the field. It is transferred to a floater type application unit, and finally either injected into the soil or applied to the surface. Application timing and method are in coordination with the farmer.
The Land Application Program exists so that the City can recycle the biosolids. In turn, the program is very beneficial to landowners and farmers because of the free source of nutrients that enables them to cut fertilizer costs. The City has lime applied to the fields to achieve a proper pH of 5.5. The sites are soil sampled on a regular basis, and information forwarded to the landowners and farmers. The Environmental Protection Agency and Indiana Department of Environmental Management regulate applications to protect soil and water quality.
A spirit of cooperation prevails between municipal government and agricultural producers to the mutual benefit received by both parties. If you are interested in additional information, you may contact the Wastewater Treatment Plant.
Combined Sewer Overflows (CSOs) are a major water pollution concern for the approximately 900 cities in the United States that have combined sewer systems. This includes our own Lafayette, which currently has 11 overflow points permitted by the Indiana Department of Environmental Management. Learn more about CSOs...
