The city council is looking at an across-the-board fee on all business and residential customer monthly bills to cover the cost of the upgrade.
City Clerk Steven Hicks says the council appeared ready to levy a $5.25 fee.
But due to the protest of a number of homeowners, they felt large commercial water users' should pay more.
The city council is expected to approve an across-the-board fee next month.
That expense has not been set at this time.
