Generally speaking, most grease interceptors must be serviced at least every 90 days. We can help with questions about the technical requirements of the regulation. (1) Every oil interceptor shall be provided with 2 vent pipe s that, (a) connect to the interceptor at opposite ends, (b) extend independently to open air, (c) terminate not less than 2 000 mm above ground and at elevations differing by at least 300 mm, and (d) do not connect to each other or any other vent pipe. Manufacturer's want to provide guidance for a broad range of installations without providing detailed drawings for every single installation variable that can exist. Both HGIs and GRDs are sized based on the flow rate of the waste stream in gpm. Most inspectors would say yes because the unit itself is trapped and a trap needs a vent, but if you ask the inspectors in Los Angeles City, they would say no, due to the fact that each fixture upstream of the trap is individually vented. 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. Hydromechanical Grease Interceptors (HGI). @le&exDxX 0 Extremely large volume GIs may have three compartments; While operating at the GI's rated flow capacity, the first compartment must provide a retention time of no less than seven minutes, and the second compartment must provide a retention time of no less than five minutes (~60/40 split); GI inverts and vents shall be external to the compartments. h[YoG+hc` @ek= K;ZoR[&&yTVvUeA3+C+iJ This is best done with an empty grease interceptor.

Schierlocated in Shawnee, Kansasis a privately-owned, 100% USA-made manufacturer of a premier lineup of high-capacity, lifetime guaranteed grease interceptors for commercial kitchens. It depends on which model plumbing code applies to the installation. Standards also come into play when it comes to determining the type and location of vents upstream of a grease interceptor. 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. These large central units are often buried outside or hidden in a parking garage. If you would like Metro Vancouver to review your grease interceptor installation plan, replacement plan, or fixture connection plan, please fill out this form: If the grease interceptor contained greater than 25% fats, oils, grease, and solids, you must have it pumped out and cleaned immediately, then provide us with the documentation from your service provider.

(c) terminate not less than 2 000 mm above ground. There are no moving parts, but there is a series of baffles that catch the grease in the waste stream creating a hydromechanical process. Grease interceptors must be selected according to our: The service provider can provide advice on how to configure a solution for your specific situation. To separate them from water an interceptor provides a separation chamber which allows FOG to rise to the surface. Metro Vancouver respects the diverse and distinct histories, languages, and cultures of First Nations, Mtis, and Inuit, which collectively enrich our lives and the region. The location of gravity grease interceptors is critical. Austin Waters Office of Industrial Waste (IW) modified its grease interceptor policies in April 2021. The purpose of a grease interceptor is to catch and collect fats, oils, grease, and solids (FOGS) from commercial and restaurant kitchens. Exterior grease interceptors shall receive the entire waste discharge from kitchens or food processing areas. As with the gravity grease interceptors, the sizing of the vent is ambiguous. HGIs are generally made from lined steel and are much smaller than gravity grease interceptors. I would size it as half the size of the inlet with a 2-inchminimum, but your AHJ might want you to use the connected fixture units so it is worth checking with your AHJ.

As waste water flows through a kitchens plumbing (3-compartment sinks, prep sinks, mop sinks, dishwashers, floor drains, etc.) Most jurisdictions would say no because the interceptor is trapped internally. These take two basic forms, hydromechanical grease interceptors (HGIs) or automatic grease removal devices (GRDs). If such is the case, they should be piped to the vent system and not left plugged, otherwise it may void the interceptor warranty. Some years ago, I was successful in getting a sizing table written in to Chapter 10 of the UPC relating fixture units to grease interceptor size, but the IPC still does not have such a table so it remains a mystery in that code. %PDF-1.5 % Wastewater leaving the grease interceptor must not exceed 300 mg/L of oil and grease and 600 mg/L of solids. PDI G101 mandates the installation of a vented external flow control. The sizing of common venting is specified in Table 911.3. The code does allow the interceptor to serve as a trap (assuming that this interceptor is intended to serve as a fixture trap) thus adding a trap to the fixture upstream of the interceptor creates a double trapped fixture installation. (8) Where an acid waste dilution tank is installed, it shall be provided with a vent pipe connected at the top of the tank and that is sized in accordance with Article 7.5.7.7. State regulations are updated quarterly; we currently have two versions available.

Manufacturer's want to provide guidance for a broad range of installations without providing detailed drawings for every single installation variable that can exist. Both HGIs and GRDs are sized based on the flow rate of the waste stream in gpm. Most inspectors would say yes because the unit itself is trapped and a trap needs a vent, but if you ask the inspectors in Los Angeles City, they would say no, due to the fact that each fixture upstream of the trap is individually vented. 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. Hydromechanical Grease Interceptors (HGI). @le&exDxX 0 Extremely large volume GIs may have three compartments; While operating at the GI's rated flow capacity, the first compartment must provide a retention time of no less than seven minutes, and the second compartment must provide a retention time of no less than five minutes (~60/40 split); GI inverts and vents shall be external to the compartments. h[YoG+hc` @ek= K;ZoR[&&yTVvUeA3+C+iJ This is best done with an empty grease interceptor.

Schierlocated in Shawnee, Kansasis a privately-owned, 100% USA-made manufacturer of a premier lineup of high-capacity, lifetime guaranteed grease interceptors for commercial kitchens. It depends on which model plumbing code applies to the installation. Standards also come into play when it comes to determining the type and location of vents upstream of a grease interceptor. 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. These large central units are often buried outside or hidden in a parking garage. If you would like Metro Vancouver to review your grease interceptor installation plan, replacement plan, or fixture connection plan, please fill out this form: If the grease interceptor contained greater than 25% fats, oils, grease, and solids, you must have it pumped out and cleaned immediately, then provide us with the documentation from your service provider.

(c) terminate not less than 2 000 mm above ground. There are no moving parts, but there is a series of baffles that catch the grease in the waste stream creating a hydromechanical process. Grease interceptors must be selected according to our: The service provider can provide advice on how to configure a solution for your specific situation. To separate them from water an interceptor provides a separation chamber which allows FOG to rise to the surface. Metro Vancouver respects the diverse and distinct histories, languages, and cultures of First Nations, Mtis, and Inuit, which collectively enrich our lives and the region. The location of gravity grease interceptors is critical. Austin Waters Office of Industrial Waste (IW) modified its grease interceptor policies in April 2021. The purpose of a grease interceptor is to catch and collect fats, oils, grease, and solids (FOGS) from commercial and restaurant kitchens. Exterior grease interceptors shall receive the entire waste discharge from kitchens or food processing areas. As with the gravity grease interceptors, the sizing of the vent is ambiguous. HGIs are generally made from lined steel and are much smaller than gravity grease interceptors. I would size it as half the size of the inlet with a 2-inchminimum, but your AHJ might want you to use the connected fixture units so it is worth checking with your AHJ. Code 4101:3-10-01 - Traps, interceptors and separators. If you are installing a grease interceptor, use our online tool for correct sizing.

As waste water flows through a kitchens plumbing (3-compartment sinks, prep sinks, mop sinks, dishwashers, floor drains, etc.) Most jurisdictions would say no because the interceptor is trapped internally. These take two basic forms, hydromechanical grease interceptors (HGIs) or automatic grease removal devices (GRDs). If such is the case, they should be piped to the vent system and not left plugged, otherwise it may void the interceptor warranty. Some years ago, I was successful in getting a sizing table written in to Chapter 10 of the UPC relating fixture units to grease interceptor size, but the IPC still does not have such a table so it remains a mystery in that code. %PDF-1.5 % Wastewater leaving the grease interceptor must not exceed 300 mg/L of oil and grease and 600 mg/L of solids. PDI G101 mandates the installation of a vented external flow control. The sizing of common venting is specified in Table 911.3. The code does allow the interceptor to serve as a trap (assuming that this interceptor is intended to serve as a fixture trap) thus adding a trap to the fixture upstream of the interceptor creates a double trapped fixture installation. (8) Where an acid waste dilution tank is installed, it shall be provided with a vent pipe connected at the top of the tank and that is sized in accordance with Article 7.5.7.7. State regulations are updated quarterly; we currently have two versions available.
