Billing Information
Water & Sewer service is billed bi-monthly (every other month). Water charges are based on the usage calculated by automatic meter reads. Sewer charges are based on the water consumption, with the exception of two consecutive billing cycles during summer months in which consumption is billed as a seasonal average due to lawn watering, car washing, etc. This average is applied for residential customers within the city limits only.
