River Water Quality 

Combined Sewer Overflows (CSOs) and other sources may contribute to high bacteria levels and river water quality degradation. Water quality is considered to be degraded if levels of bacteria are greater than the standard set by the Indiana Department of Environmental Management (IDEM) for fishing and swimming. The water quality standard set by IDEM for e. coli bacteria is 235 organisms per 100 mls of water.

Weekly River Water Quality Report

Water quality testing is performed weekly between April 1 and October 31 of each year.
Testing of samples as of July 16, 2018
            20 organisms/100 ml at the Ferguson Bridge on the St. Marys 
            29 organisms/100 ml at the Mayhew Bridge on the St. Joseph
           186 organisms/100 ml at the Tennessee Bridge on the St. Joseph 
            26 organisms/100 ml at the Anthony Bridge on the Maumee 
            20 organisms/100 ml at the Landin Bridge on the Maumee
            40 organisms/100 ml at the Spy Run Bridge on the St. Marys


 General River Water Quality Measurements and Conditions

A variety of scientific parameters (chemical and physical measurements) make up river water quality. Bacteria, as noted above, are of particular concern to human health so this parameter is routinely measured and reported here. Other parameters are also routinely measured to help quantify overall river health. More information about these measurements, common values, and overall river conditions are explained on our Watershed Protection page.

Testing for Drinking Water Safety 

City Utilities tests drinking water for safety and quality throughout the water treatment process. Continuous monitoring of the water that comes from the St. Joseph River helps operators at the plant adjust the treatment process to the most effective level based on incoming water conditions.
Chemists at the plant test the water that goes out to customers for more than 120 substances. City Utilities also collects water samples from homes and businesses around the community to make sure the water arriving at the customers' taps remains safe.
Each year City Utilities publishes an annual water quality report showing the levels of substances commonly found in drinking water supplies.

City Utilities Facilities 

IMG 8436Have you ever wondered about the buildings where the City filters your drinking water? City Utilities operates a number of water-related facilities including the Three Rivers Water Filtration Plant, Water Pollution Control Plant, Hurshtown Reservoir, Camp Scott, and others. Read more below about two of the main drinking facilities. 

For more information on drinking water quality or to schedule a tour of the pdfThree Rivers Water Filtration Plant, please call City Utilities by dialing 311 or (260) 427-8311.

Water Distribution and storage

Once the water is treated at the Three Rivers Water Filtration Plant, it is held in a 20 million gallon underground storage reservoir just outside the plant until it is pumped out into the distribution system. Water is distributed to 5 elevated storage tanks around the City where it is stored until needed. The tanks also help maintain water pressure in the outskirts of the distribution system. Water travels through more than 1,160 miles of water mains to the 250,000 customers served by the Fort Wayne water utility.

Fort Wayne City Utilities operates several reservoirs that help to ensure an adequate supply of water for the City. Water can be impounded in the Cedarville Reservoir at Leo-Cedarville at the St. Joe River Dam near Johnny Appleseed Park. City Utilities also has a man-made reservoir near Grabill called the pdfHurshtown Reservoir
