Food Establishment Plumbing Requirements Guide
PLUMBING FIXTURE REQUIREMENTS
Utensil Washing Sink ‐ A utensil washing sink, normally one or three compartments, with all
compartments/basins sized to immerse the largest item to be washed, must be provided.
Three compartment sinks are routinely required for all food facilities preparing potentially
hazardous food. An exemption to a three‐compartment sink may be granted based upon
individual review of menu and complexity of operation. Plumbing Code requires a direct
connection for a utensil washing sink which may or may not have a grease trap.
Grease Trap or Interceptor ‐ The mandatory installation and sizing of grease trap units are
regulatory requirements governed by the Industrial Waste Unit of the Water Department.
The piping to the grease trap is regulated by the Plumbing Code. A sink plumbed to a
grease trap may not have the normally required trapped drain. In particular food
processing applications when significant quantities of grease or fat may be discharged a
grease trap may precede the required indirect waste connection. The installation of a
grease trap must allow for adequate clearance, at least six inches, between it and adjacent
equipment or walls so as to facilitate cleaning of the area. In addition, the location of the
grease trap must allow for easy servicing and maintenance of the unit itself.
Hand Washing Facilities ‐ Conveniently located hand washing facilities are required for all food
service areas. Hand washing sinks in toilet rooms are not approved as a means of meeting
this requirement. Approval for the use of a sink other than a specific hand wash sink, i.e.
utility sink, janitorial sink, garbage grinder sink, for meeting hand washing facility
requirements may be considered upon review of the operation and facility design.
Food Preparation ‐ A separate food preparation sink plumbed with an indirect waste
connection to the plumbing system is required when menu or food preparation practices
indicate the need for such equipment. Typically, full service restaurants, salad bar, and
seafood operations require food preparation sinks.
Installation Location Criteria ‐ Food preparation sinks as well as other food contact surfaces
must be protected from potential sources of contamination. Example: A minimum
separation space of two feet is required between a food preparation sink and adjacent hand
wash or utensil sink. An approved physical barrier may be considered as an alternative
means of protection.
Garbage Grinders ‐ Food establishments installing garbage grinders in accordance with the
Streets Department requirements must comply with Plumbing Code and Health Code
requirements. Due to physical plumbing requirements for the installation of commercial
grinders their installation is normally limited to being provided in a separate dedicated sink
or as part of an automated dishwashing system‐‐i.e. scrap sink or scraping trough. When
