Those customers’ average water use during their respective windows will determine monthly sewer charges beginning April 1, 2027. The city says it will average water usage readings during the applicable period and use that figure to calculate the charge for the following 12 months.
The published calculation for an average below 12,000 gallons per month is a $17.71 base rate plus $5.57 per 1,000 gallons of average use. For an average above 12,000 gallons, the city lists $5.57 per 1,000 gallons for the first 12,000 gallons and $13.37 per 1,000 gallons above that threshold, plus the base rate. These are rates stated in the city’s notice; the notice does not announce a newly adopted rate.
