Oil/sand interceptors contain one to four compartments (basins) where oil separates and floats to the surface, while sand and grit settle to the bottom sludge baffle. Denser, cleaner water flows through the compartment(s) until it is discharged from the interceptor.
What is interceptor maintenance?
Cleaning Oil and Petrol Interceptors One of the primary regular tasks to be undertaken is cleaning the channel drain, and removing any oil and petrol that has accumulated on the surface. … As with the cleaning of the tanks, special care should be taken to prevent any pollutants escaping.
Is a grease trap the same as an oil water separator?
This causes the removal of more oil from the water stream. Oil separators also have higher capacity ratings meaning that they can be used for much higher water flow rates than grease interceptors. … This makes the oil separator ineffective and has the potential to allow oil to escape into the trade waste sewer.
How do you size a sand interceptor?
The size of the interceptor is determined by the GPM discharge rate of the dishwasher as specified by the manufacturer. Many local plumbing inspectors require that grease laden wastewater flowing into floor drains must flow through a grease interceptor before draining into the sanitary sewer system.
Where are sand interceptors used?
Sand/oil interceptors are in-ground tanks designed to capture dirt, sand, sweepings, minor petroleum spills, etc. from car washes and vehicle maintenance facilities to keep these substances out of our wastewater system.
How often should interceptors be emptied?
The Environment Agency recommends that interceptors are cleared every six months to avoid blockages and prevent pollution of your drainage systems and the environment around your site. We can carry out regular, hassle-free interceptor emptying services to help you with you this.
How do you size an oil interceptor?
Oil Interceptors are sized according to the rate of incoming flow, in gallons per minute (GPM). For indoor applications, flow rate can be calculated by adding the maximum discharge rates of all poten- tial water sources. For example, a standard 3/4″ hose connection will discharge approx. 10 GPM.
What is an oil interceptor?
Oil interceptors separate oily waste from interior drainage systems or exterior run-off areas, preventing environmentally damaging and potentially dangerous oil substances from entering septic fields, run-off areas, and wastewater treatment facilities.
What is the maintenance cost of interceptor 650?
The estimated maintenance cost of Royal Enfield Interceptor 650 for 5 years is Rs 9,899 The first service after 5000 km, second service after 10000 km, third service after 20000 km, fourth service after 30000 km, fifth service after 40000 km and sixth service after 50000 km is free of cost.
Do grease traps need to be vented?
Grease interceptors must have a vented waste, sized in accordance with code requirements for venting traps, to retain a water seal and to prevent siphoning. One interceptor to serve multiple fixtures is recommended only where fixtures are located close together.

How many types of oil interceptors are there?
There are 2 main types of Petrol/Oil Interceptor; Full Retention Interceptors, which are designed to treat the full flow delivered by a drainage system up to 50 mm/hr. Bypass Interceptors which, are designed to treat flows of up to 5 mm/hr. This covers 99% of rainfall.
Is a grease trap and interceptor the same?
Whether the unit is a grease trap or grease interceptor, the technology works the same. … The difference between a grease trap and a grease interceptor is the flow rate of wastewater that the device can handle. A grease trap works well with a lower volume of flow; less than 50 gallons per minute.
Do I need a grease interceptor?
A grease trap or grease interceptor is required for any facility that pushes wastewater with fats, oils, or grease into the sewage system.
What is a hydromechanical grease interceptor?
Hydromechanical grease interceptors (HGIs) (formerly named grease traps) treat kitchen wastewater from food service establishments (FSEs) using gravity separation aided by vented flow control. They are typically installed indoors and connected to one to four sinks in the kitchen and can be either above floor or below.
Why do we have gullies and interceptors on the forecourt?
It is typically used in road construction and on Petrol Station forecourts to prevent fuel contamination of streams carrying away the runoff. … However some of the contaminants may by chance enter the second tank. This second tank will not build up as much of the hydrocarbon on its surface.
What is interceptor waste?
What is Interceptor Waste ? Interceptors, are also known as oil, grease and water traps or separators, and are fitted to drainage systems in order to separate wastewater from oil, silt, dirt and any other harmful contaminants and therefore prevent pollution of the local watercourse.
Is interceptor waste hazardous?

What is an interceptor drain?
Drain interceptors or drain separators are seen as the final line of drainage defence. They are designed to stop contaminants from commercial and industrial sites (such as production facilities, storage areas and even car parks) from creating a pollution hazard.
Will there be a Himalayan 650?
At first, the 650 Himalayan project was cancelled but now it has been given a green light. The new motorcycle is expected to launch in the last quarter of 2024. According to media reports, it has been 18 months since the development of Himalayan 650 started.
How does an oil seperator work?
Oil water separators are designed specifically to target oil based on the gravity difference between oil and water, allowing for heavier solids (sludge) to settle to the bottom while oil rises to the top, leaving additional wastewater in the middle layer.
How does a drain interceptor work?
How do drainage interceptors work? Most standard drain interceptors comprise of a series of chambers, or tanks, which hold the water and separate contaminants in two ways: Heavy solids within the wastewater fall to the bottom of the tank. Lighter oils, fuels, and chemicals float on the top of the water.
What is a triple interceptor and what is it used for?
Triple Interceptor Waste Removal and Cleaning You may also find them in car-parks and are used to intercept oil and petrol contained in the storm water run-off. The purpose of a triple interceptor is to separate water coming from the drainage system from any contaminants such as fuel, oil, silt, dirt and brake dust.
Can you wet vent a grease interceptor?
A grease interceptor must not and cannot receive any sanitary waste water (for example, from a toilet). Waste water discharge into a grease interceptor can only be from food service fixtures.
Where do you put a grease trap?
The most convenient place to install a grease trap is beneath your sink but it can also be installed outside your home. Unless your home has several sinks that are regularly used for cooking, setting it up beneath your sink is recommended.
How do you size a grease trap?
L x W x D to give you X as the capacity of the sink then X/231 to give you Y as the flow rate in gallons per minute (GPM). Then Y multiplied by 0.75 to give you the size of the grease trap you will need for your commercial kitchen.
What is a water interceptor?
An interceptor drain, also known as a curtain drain, is a drainage system that is installed to collect, channel and remove surface and subsurface water within permeable soil as it flows across an impermeable soil layer.
