The total bill, plus a $5.00 service charge for the expenses connected with the disconnect notice must be paid within five working days of the date of the disconnect notice or service will be terminated per order of the superintendent. If a resident receives two disconnect notices within one year, a one time additional deposit of $100 is required.  Once the disconnect order is issued, there is a $25.00 fee added to the balance due.
