Combined sewer overflows and sewer systems

Yes, regarding CSO (Combined Sewer Overflow)
During rain events, the combined rain runoff (or “stormwater”) from the streets along with wastewater from homes and buildings can overwhelm the capacity of the combined sewer mains. To prevent this excess capacity from backing up into streets or basements, the systems were designed with outfalls that empty this excess capacity into waterways. Each discharge event into a waterway is known as a “combined sewer overflow,” or CSO.
