Fat, oil, grease bad for health of sewer system


WILLMAR -- Just as plaque buildup in arteries restricts blood supply and can cause a heart attack, accumulation of fats, oils and grease in sewer lines can cause health hazards, damage home interiors and threaten the environment.

"Think about it like heart disease,'' says Chris King, an operator at Willmar's Wastewater Treatment Plant. "If you put a lot of fats, oils and grease in your body, it's going to clog your arteries. The same thing with sewer lines.''
