A portion of the condition around is a combined sewer program one to delivers both violent storm drinking water and you may hygienic sewage in one single tubing.

Shared Sewer Overflows . A remedy
During the 1972, the staff of one’s Section out-of Absolute Waters is significantly improved. Personnel had been put into brand new Department getting design government, having functions, and believe and you may construction really works. Just after becoming guilty of the newest operation and you can restoration of your Rochester sewerage program in the summertime off 1972, the fresh new section began to gauge the dilemma of combined sewer overflows (CSOs) by way of an in depth writeup on the brand new procedure of one’s overflow system and of currently accomplished degree.
