The NYC Department of Environmental Protection (DEP) Bureau of Water & Sewer Operations has issued a comprehensive guide for property owners on setting up backflow prevention plans, a critical aspect of safeguarding the city's water supply. This guidance is an essential supplement to the New York State Department of Health Handbook for Cross Connection Control, aimed at preventing the potential risk of contamination. Owners of a wide variety of properties, including but not limited to bakeries, auto repair shops, beauty salons, and medical offices, are required to install backflow prevention devices. These devices ensure that contaminated water does not flow back into the city's drinking water system. The process of compliance, as outlined by the DEP, involves the preparation and submission of plans by a licensed Professional Engineer (PE) or Registered Architect (RA), installation by a licensed plumber according to these plans, followed by testing and annual inspections. For owners seeking exemptions or navigating the complexities of installation, professional consultation is advised. This initiative, enforced through specific sections of the State Sanitary Code and the Rules of the City of New York, highlights the DEP’s commitment to maintaining the integrity and safety of the water supply, thereby protecting public health.

BUREAU OF WATER & SEWER OPERATIONS
REVISED SUPPLEMENT TO THE NEW YORK STATE DEPARTMENT OF HEALTH HANDBOOK FOR CROSS CONNECTION CONTROL
This supplement was last revised on (6/10)
Introductory Note:
This supplement will help you prepare backflow prevention plans for submittal. It is a guide only and should not be used as a substitute for experience in the planning and design of backflow prevention device installations. If you are not experienced with this type of work, we suggest that you consult with a professional.
To avoid the expense and delay necessitated by the removal and reinstallation of containment devices, we suggest that you have your plans approved by DEP before proceeding with installation.
For new facilities, aesthetic considerations and architectural design is an unacceptable reason for granting exemptions. The architectural design must accommodate the containment devices, not the other way around.
Please note that the filing Professional Engineer or Registered Architect is expected to review the potential for hazard posed by the occupancy of the premises.
Based upon this review, the filing Professional Engineer or Registered Architect should select an appropriate containment device in accordance with the latest revision of the DEP Cross Connection Control Risk Assessment.
