MT. VERNON — The city of Mt. Vernon is in year three of its long-term plan to fully upgrade its water and sewer system, and the city is already seeing a drop in leaks in the system.

Mt. Vernon City Manager Mary Ellen Bechtel says about five miles of lines are scheduled to be replaced in 2020.

Bechtel says the city still has about 97 miles of lines to replace in their ongoing improvement effort.
