A deposit will also be added to active utility accounts if service is disconnected for non-payment. The deposit shall be applied to the closing bill upon the discontinuation of services and any remaining credit will be refunded. The Residential deposit is $200 and the Commercial deposit is based on average monthly billing of location.
