Negative Impact to the Waste Water Treatment System due to Grass Clippings Left in the Street

Grass in road
The City of Ogdensburg and surrounding areas are served by separated and combined sewers systems which convey both sanitary sewage and storm water to the Wastewater Treatment Plant (WWTP) located at Railroad Street before being discharged to the St, Lawrence River.  During heavy rainfall events, the combined sewage and stormwater flows may exceed the capacity of the collection system and/or the WWTP and overflow directly to the receiving waters at permitted locations on the St. Lawrence and Oswegatchie Rivers. These events are known as Combined Sewer Overflows (CSOs).

When substantial rainfall occurs, foreign debris collected in our streets can enter the storm water collection system and combine with the sanitary sewer, placing significant additional organic and inorganic load on our WWTP and local waterways.  Examples of such debris is:  paper, leaves, tree branches, mowed grass clippings, etc.  These items of debris added to our Combined Sewers adds additional costs to our WWTP treatment processes, shortens equipment life and increases collection system cleaning/maintenance expenses.

With the help of our residents we can reduce these expenses by keeping our property street fronts clean of such debris and be ever mindful of the effect these items have on our Treatment Plant/Collection System costs to provide and maintain these services.

We thank you in advance for your cooperation.
