You probably know the devastating effects of a blocked drain system on your health and environment: stagnant pools of water, the dreadfully musty odor, and the possible mosquito infestation all lining up to make living in your home an uncomfortable experience. These effects are avoidable and usually limited to the household, but it would seem not everyone is fully aware of how they can disrupt the daily flow of an entire region. Metro Vancouver reports that, the considerable amounts of grease entering the sewer is leading to big complications for their drainage systems, hindering normal movement and causing it to backflow or spill out into the streets. Also, it costs the city over 2 million dollars each year just to remove accumulated grease.
