The Sewer Utility is solely funded through fees from sewer ratepayers. The Utility does not receive any funds from County tax revenue and cannot provide any financial assistance to other public works divisions or county departments.
98% of the Sewer Utility's revenues comes from residential customers. Annual applications are made for grants and low interest loans to help extend funds and maintain reserves. The focus of the Sewer Utility is to protect public health and the environment while providing cost effective service for our customers.
