No Fats, Oils, or Greases (FOG) A simple way to prevent sewage overflows is to keep FOG out of your drains. Never pour oil or dispose of fats and grease down the drain. Even when washed down with soap and hot water, when the water cools, the FOG solidifies in your pipes.,
An increase in CSOs could result in increased influx of microbial pathogens and other pollutants into receiving waters. Besides the changes in influx, climate change is also expected to influence river flow rates. In winter time, precipitation will increase river flow rates (Middelkoop et al., 2001).Nov 15, 2016
Under normal conditions, it transports all of the wastewater it collects to a sewage treatment plant for treatment, then discharges to a water body. The volume of wastewater can sometimes exceed the capacity of the CSS or treatment plant (e.g., during heavy rainfall events or snowmelt).Nov 23, 2021
A more direct approach to preventing overflows involves creating an overflow retention basin (ORB) to capture the necessary volume at the collection system's CSO point. Such storage facilities provide an efficient means of reducing CSO occurrences and limiting pollution discharges to receiving waterways.Aug 31, 2003
Sewer back-ups and overflows are frequently caused by improper materials such as fats, oils and grease (FOG) being placed into the sewer system. Since fats, oils and grease are lighter than water; they tend to accumulate at the top and sides of sewer pipes and can build up until a blockage occurs.
