Oil Interceptor / Oil & Grease Trap
An Oil Interceptor (Oil & Grease Trap) is a wastewater treatment system designed to remove oil, grease, and suspended solids from wastewater before it enters the drainage or sewer system.
These systems are commonly installed in facilities where wastewater contains significant amounts of oil and grease, such as commercial kitchens, food processing units, automobile service stations, and industrial plants.
The interceptor works by slowing down the wastewater flow, allowing oil and grease to rise to the surface while heavier solids settle at the bottom. The separated wastewater then flows out through an outlet chamber.
Greenshield Enviro provides efficient oil interceptor systems designed to improve wastewater quality and support effective wastewater management.

Efficient Separation of Oil, Grease and Suspended Solids from Wastewater
An Oil Interceptor (Oil & Grease Trap) is a wastewater treatment system designed to remove oil, grease, and suspended solids from wastewater before it enters the drainage or sewer system.
These systems are commonly installed in facilities where wastewater contains significant amounts of oil and grease, such as commercial kitchens, food processing units, automobile service stations, and industrial plants.
The interceptor works by slowing down the wastewater flow, allowing oil and grease to rise to the surface while heavier solids settle at the bottom. The separated wastewater then flows out through an outlet chamber.
Greenshield Enviro provides efficient oil interceptor systems designed to improve wastewater quality and support effective wastewater management.
Oil interceptors are widely used as a pre-treatment system before Effluent Treatment Plants (ETP) or Sewage Treatment Plants (STP).
Wastewater containing oil and grease can cause blockages, damage sewer systems, and interfere with wastewater treatment processes.
Installing an Oil Interceptor helps organizations prevent oil and grease from entering drainage systems, reduce blockage and maintenance issues in pipelines, improve wastewater treatment efficiency, protect municipal sewer infrastructure, and improve environmental responsibility of operations.
The system can be customized depending on wastewater flow, oil content, and site conditions
Treatment Capacity
1 KLD – 100 KLD (customizable)
Construction Material
Mild Steel / FRP / RCC / HDPE
Installation Type
Above Ground or Underground
Design
Multi-Chamber Gravity Separation System
Step-by-step operational workflow
Wastewater Inlet
Wastewater containing oil, grease, and solids enters the interceptor chamber.
Flow Reduction
The flow velocity reduces inside the interceptor allowing separation to occur.
Oil & Grease Separation
Oil and grease float to the surface due to lower density compared to water.
Solids Settlement
Heavier solids settle at the bottom of the chamber.
Treated Water Outlet
Relatively cleaner water flows out through the outlet pipe to the next stage of treatment or drainage.
These systems help prevent grease and oil contamination of drainage systems

Operational and environmental value for wastewater management
Prevents grease blockages in pipelines
Helps reduce operational interruptions and improve wastewater flow management.
Reduces maintenance and plumbing costs
Supports easier long-term upkeep of drainage infrastructure.
Improves efficiency of downstream treatment systems
Creates more effective pre-treatment before ETP or STP stages.
Helps protect municipal sewer infrastructure
Supports responsible wastewater management and cleaner discharge practices.
Supporting responsible wastewater discharge management
Facilities generating wastewater containing oil and grease are often required to implement appropriate wastewater management systems.
Environmental monitoring and wastewater discharge standards are regulated by authorities such as the Central Pollution Control Board and respective state pollution control boards including Haryana State Pollution Control Board, Uttar Pradesh Pollution Control Board, and Delhi Pollution Control Committee.
Oil interceptors help facilities manage wastewater effectively and reduce oil contamination in discharge streams.
