Cross Connection Control Program

The purpose of this backflow prevention and cross-connection control program is to protect the
City’s water system from contaminants or pollutants that could enter the distribution system by
backflow from a customer’s water supply system through the service connection. As a supplier of
public drinking water, the City of Aspen has the authority to survey all service connections within
the City’s water distribution system to determine whether any connection is a cross-connection; to
control all service connections within the distribution system that are cross-connections; to charge a
fee for the administration of the cross-connection control program; to maintain records of surveys
and the installation, testing and repair of all backflow prevention assemblies permitted or required
under this program; and to administer, implement and enforce the provisions of this cross-connection
control program.
