If Tucson Water determines, after inspection of the customer's system, that a backflow prevention method less restrictive than that required in section 27-75 will provide adequate protection of the public water supply, Tucson Water may, at its sole discretion, modify or waive the requirements of section 27-75 accordingly. In determining, waiving, or modifying backflow requirements, Tucson Water shall consider the hazard potential to the public water system based on the design of the customer's water system.
