OmiDrop Africa — Waste Management Operations Team
"We've cleared overflowing grease traps for Nairobi CBD restaurants 45 minutes before a health inspection. We've serviced oil-water separators at petrol stations that hadn't been touched in three years. We've put hotel kitchens in Upper Hill on monthly FOG contracts that haven't triggered a NEMA warning since. Oil interceptor cleaning isn't a once-in-a-blue-moon job — it's a compliance rhythm, and OmiDrop keeps yours running."

What Is an Oil Interceptor — and Why Does It Need Regular Cleaning?
An oil interceptor — also called a grease trap, grease interceptor, or oil-water separator — is a plumbing device that captures fats, oils, and grease before they enter the drainage system. Without regular cleaning, interceptors block, produce foul odours, and cause sewage backflow, leading to NEMA compliance failures and costly emergency repairs.
Oil interceptors work by slowing wastewater flow so that grease, fats, and oils — which are less dense than water — float to the surface of the trap chamber, while solids settle to the bottom. The separated water exits through the outlet into the main drain. Over time, the accumulated grease and solids layers build up until they consume the trap's capacity entirely.
There are two main types OmiDrop services. Grease traps (or grease interceptors) are designed for food-service environments — restaurants, hotel kitchens, canteens, and fast food outlets — capturing kitchen fats, oils, and grease. Oil-water separators are the broader category used at petrol stations, car washes, and vehicle workshops to capture petroleum-based oils and fuel runoff before they reach drainage or groundwater.

Related services: OmiDrop's oil interceptor cleaning is a natural complement to our exhauster and septic tank siphoning and drain unblocking services — many commercial properties benefit from all three on a coordinated maintenance schedule.
Which Businesses Need Oil Interceptor Cleaning in Kenya?
Any commercial premises that produces cooking waste, processes oils, or handles fuel and vehicle fluids is legally required to manage its oil and grease waste. In Kenya, this includes restaurants, hotels, petrol stations, car washes, hospitals, schools, and industrial facilities — all of which require regular, documented interceptor maintenance to remain NEMA-compliant.

"Our petrol station oil-water separator had never been professionally serviced. OmiDrop's team inspected it, cleaned it fully, and gave us a maintenance schedule. They explained NEMA requirements we weren't even aware of. Thorough, professional, and the paperwork was ready the same day."
Frequently Asked Questions About Oil Interceptor & Grease Trap Cleaning
An oil interceptor (or grease trap) is a plumbing device that captures fats, oils, and grease before they enter the drain or sewer system. Over time, intercepted grease solidifies and builds up. Without regular cleaning, it causes blockages, foul odours, sewage backflow, and NEMA compliance failures. Regular cleaning restores the interceptor's capacity, protects your drainage system, and keeps your business legally compliant. See also our exhauster and septic siphoning services for the broader waste management picture.
For commercial kitchens in Kenya, oil interceptors should be cleaned every 1–3 months, depending on cooking volume and fat usage. High-volume restaurants typically need monthly cleaning. Petrol station oil-water separators are usually cleaned quarterly. A practical rule: when grease and solids together fill more than 25% of the trap's depth, it needs servicing. OmiDrop can inspect your interceptor and recommend the right schedule for your operation. WhatsApp us for a free assessment.
An uncleaned interceptor will eventually block, overflow, and allow grease and oils into the main sewer system. This causes drain blockages, sewage backflow into your business, foul odours, pest attraction, and can result in NEMA enforcement action, fines, or temporary closure orders. The cost of regular scheduled cleaning is significantly lower than emergency call-outs and compliance penalties combined.
Yes. NEMA (National Environment Management Authority) regulations under the Environmental Management and Co-ordination Act (EMCA) require commercial premises to manage and dispose of grease, oils, and wastewater responsibly. Unmaintained oil interceptors can result in NEMA enforcement notices, fines, or licence complications. OmiDrop provides NEMA-compliant disposal and can supply written service documentation for compliance records and audits. See also our compliance and certifications page.
Yes. Petrol stations are required to have oil-water separators that capture fuel and oil runoff from forecourts and service bays before it reaches drainage or groundwater. These separators require regular emptying and cleaning — typically quarterly — to remain effective and NEMA-compliant. OmiDrop provides oil-water separator cleaning for petrol stations, vehicle workshops, and car wash operators across Kenya.
The terms are often used interchangeably, but there is a distinction. A grease trap (or grease interceptor) is specifically designed for food-service environments — capturing fats, oils, and grease from kitchen drainage. An oil interceptor (or oil-water separator) is a broader term covering devices at petrol stations, car washes, and industrial sites that capture petroleum-based oils and fuels. OmiDrop cleans both types across all sectors.
A standard grease trap cleaning takes 1–3 hours, depending on interceptor size and condition. Heavily neglected or large industrial interceptors may take longer. OmiDrop technicians arrive fully equipped and handle the job from start to finish — including responsible off-site waste disposal — so your team can continue operations with minimal disruption.
Yes. OmiDrop offers scheduled FOG (fats, oils, and grease) management contracts for hotels, restaurant groups, commercial kitchens, and property managers. Contracts include regular cleaning at agreed intervals (monthly or quarterly), priority emergency call-out, and service documentation for compliance records. Contact us to build a maintenance schedule suited to your business — contracted clients receive 10–15% lower rates than ad-hoc bookings.
