The proposals were made following a rate study conducted by financial firm Umbaugh and Associates. That review took into account infrastructure needs for maintaining both services at an appropriate level.
Knox Mayor Rick Chambers has previously noted the two rates proposed for amendment have not increased in eight years.
Under the proposals, changes in water rates will take effect immediately following approval. Sewer rates will be implemented in two phases: the first anticipated to take place in 2016, and Phase Two scheduled for implementation in January, 2017.
According to a minimum bill comparison for total water and sewer rates, consumers can expect to see a nearly $13 increase in 2016. Prices would increase another $7 the year after.
Knox Clerk-Treasurer Jeff Houston says the ordinance amendments will see a public hearing, and perhaps approval on second and third reading, in January.
The ordinance amendments were approved on first reading, Tuesday night.
