Metro Vancouver's Food Sector Grease Interceptor Bylaw 268 requires commercial and institutional kitchens to install and maintain a grease interceptor to reduce fats, oils and grease (FOG) in the sewer system. In the last 20 years we have grown from a small regional company to the most widely specified and inventoried (sold through plumbing wholesale) brand of grease interceptors in the U.S. Our expertise in navigating codes, standards, compliance, specifications and installations is unparalleled in the industry. Conceptual drawing of a City of Austin approvedgravity grease interceptordesign, View contact information for grease trap manufacturers. . Manufacturer's want to provide guidance for a broad range of installations without providing detailed drawings for every single installation variable that can exist. As waste water flows through a kitchen's plumbing (3-compartment sinks, prep sinks, mop sinks, dishwashers, floor drains, etc.) L/m, 1 pound = 0.454 kg. A final requirement is that water flowing through a grease interceptor must not have a temperature above 180F. Determining the gpm is tricky since the piping is sized based on fixture units. Model plumbing codes require each fixture discharging into a grease interceptor be individually trapped and vented, and require the installation of a vent downstream of the grease interceptor. GRDs are trickier to size than HGIs. If you do provide a vent, how do you size it? The International Plumbing Code (IPC) 1002.1 (exception 3) allows a grease interceptor to serve as a fixture trap - where it is intended by the manufacturer to serve as a trap - for a single fixture or a combination sink of not more than three compartments so long as the vertical distance from the outlet of the fixture to the inlet of the interceptor is not more than 30 inches and the developed length of the waste pipe from the most upstream fixture outlet to the inlet of the interceptor does not exceed 60 inches. 4. refer to local plumbing code for venting, fixtures, and trap requirements. These take two basic forms, hydromechanical grease interceptors (HGIs) or automatic grease removal devices (GRDs). Manufacturer's are required to identify which Type their interceptor is rated to when certifying to the ASME standard. 2y.-;!KZ ^i"L0- @8(r;q7Ly&Qq4j|9 A grease interceptor shall be provided for proper handling of liquid wastes containing grease.

Protection Agency", or the authority in charge of the sewerage system into If you are designing in the UPC, there is a table in the Code for sizing the interceptors based on pipe size and associated peak flow rate, and then assigns interceptor sizes based on one-minute and two-minute drain down times. Note that HGIs are generally located recessed into the floor or on the floor below if that is possible. hb```Lf yAXarPw`vB/+2[aa&]eL3DT -ke&{:2CFGC`h B j` SD 7.5.5.2. venting ="http://thehandyforce.com/interior/bathroom-renovations/" title ="Toronto Bathroom renovation inspiration">venting of Interceptors.

Grease interceptors must be selected according to our: The service provider can provide advice on how to configure a solution for your specific situation. a) All required grease interceptors shall comply with the following: 1) Material and Covers. @le&exDxX Both HGIs and GRDs are sized based on the flow rate of the waste stream in gpm. A vent shall be installed downstream of hydromechanical grease interceptors in accordance with the requirements of this code. Plus, since our new president was just elected, nobody knows what we have in store for 2017 lets hope it is good! As waste water flows through a kitchens plumbing (3-compartment sinks, prep sinks, mop sinks, dishwashers, floor drains, etc.) Exterior grease interceptors shall receive the entire waste discharge from kitchens or food processing areas. Grease interceptor means a multi - compartment . To separate them from water an interceptor provides a separation chamber which allows FOG to rise to the surface.

For SI: 1 gallon per minute = 3.785 Please turn on JavaScript and try again. As the waste stream flows through the orifice in the flow control device negative pressure is created, drawing in air from the air intake which is intended to mix with the waste water as it enters the grease interceptor aiding in separation efficiency. Generally speaking, most grease interceptors must be serviced at least every 90 days. (5) Every vent pipe that serves an oil or grease interceptor and is located outside a building shall be not less than 3 in. What's important to remember about AAVs is that they only allow for the relief of negative pressure in the drainage system. Or do you size it based on the number of fixture units connected upstream? . HGIs greater than 500 gallons must have a 60/40 split between compartments. dwellings. A grease interceptor or automatic grease removal device shall be required to receive the drainage from fixtures and equipment with grease-laden waste located in food preparation areas, such as in restaurants, hotel kitchens, hospitals, school kitchens, bars, factory cafeterias and clubs.
