Assessment and Sewer Use Billing

Assessment bills are mailed out once a year in the month of July. The assessment is considered a lien against your property until paid in full. Should you sell or transfer your property, the assessment including any suspended amount becomes due and payable in full.

At the June, 2016 meeting, the Sewer Commission voted to change to an annual billing that can be paid in quarterly payments. Residential sewer use bills will be mailed each October. The quarterly due dates with grace periods are as follows: 1st quarter due 10/31 grace period 11/14, 2nd quarter due 1/31 grace period 2/14, 3rd quarter due 4/30 grace period 5/14 and 4th quarter due 7/31 grace period 8/14. 

As of July, 2025 the residential rate is set at $700.00 per dwelling unitl per annum which breaks down to $175.00 per unit/billing. This rate shows on the bill mailed in October 2025.

Commercial/Industrial sewer use bills are mailed out quarterly and are based on water consumption readings. Bills are mailed in February, May, August and November. The rate is currently set at $123.10 per 1,000 cubic feet.  

Failure to receive a sewer use bill/assessment bill does not excuse anyone from paying these bills plus penalties. Bills are due and payable on the last day of the current month of the bill. Penalty is assessed from the 15th day of the next month.
