Grease cutting preventative maintenance concentrates on identified / designated problem areas. Grease is a major problem in the City and takes considerable man and equipment hours. This flushing and cutting effort maintains approximately 36,000 meters of line as part of the annual grease control program, cleaning lines where stoppages or significant problems occur, in an attempt to ensure that sanitary sewer lines remain clear. The additional cleaning of locations with chronic blockage problems is performed monthly. These blockages are typically caused by or aggravated by reoccurring grease accumulations in the sanitary sewer pipes. A program to implement a City program targeting high grease accumulation areas is currently under development. If significant grease is discovered within the service connection the City will issue a letter to the owner giving notice of the by-law infraction and request the necessary action be taken to prevent the further discharge of grease into the system.
