A public hearing was held Tuesday and the rate change was approved unanimously by the four board members who attended the meeting.
The rate change means residential customers will see their monthly bills rise from $42 to $47.
The change is effective this month. Coupon books will be updated and distributed to customers with the new rate, said Clerk-Treasurer Kent Adams.
Sewer service for Winona Lake is provided by the city of Warsaw, which recently adopted a rate change intended to fund a two-part $41 million overhaul of the treatment plant and related infrastructure.
The first phase of construction involves a $10 million effort to repair and replace many sewer lines and some manholes in the city later this year.
Some of the sewer lines are more than 100 years old and many are deteriorating.
The second phase involves expansion of the treatment plant, which is near capacity.
Warsaw’s rate hike was approved last year and will support phase one.
Another rate hike will be initiated this year by the city to fund the second phase.
Winona Lake Town Council will consider another rate hike after Warsaw City Council takes action later this year.
Only one member of the public attended Tuesday’s public hearing, but he did not speak.
