Professional Grease Trap Cleaning for Food Businesses in Singapore
When grease builds up in the grease trap, it does not stay there for long. It starts to affect the flow, produce odours, and increase the risk of blockages from the kitchen to the sewer connection. At Direct Plumber SG, we provide grease trap cleaning for restaurants, coffee shops, hawker centres, food courts, central kitchens and other food establishments across Singapore.
A grease trap is designed to separate fat, oil and grease from used water before that wastewater enters the sewerage system, and PUB notes that poor grease trap maintenance can lead to odours, flow obstruction and overflow into premises or public areas.
If your grease trap is overdue for cleaning, smells unpleasant, drains slowly, or shows signs of overflow, our team can help. We properly clean a grease trap, remove accumulated FOG, inspect key components, and recommend the right cleaning frequency for your business.
Whether you operate in a mall unit, a standalone restaurant, a food factory or a hawker setting, we deliver a practical solution with a soft-touch, no-pressure quote before work starts.
Common Grease Trap Issues We Solve
Our 4 Step Process
Discover our effective grease trap cleaning process.
Step 1: Inspection and Diagnosis Before Cleaning
Every grease trap cleaning job should start with inspection, not guesswork. We first assess the location of the grease trap, the condition of the surrounding pipes, access covers, and inspection chambers, and the flow pattern from the kitchen fixtures. This matters because different types of grease traps, grease interceptors and layouts behave differently under load. A small under-sink device in the kitchen is not the same as a larger outdoor system serving multiple kitchens or food tenants.
We look for signs of poor flow, hardened fats, oils, food solids, damaged components, unusual odours and overflow marks. We also check whether the grease trap is easy to access for maintenance. NEA’s Code of Practice on Environmental Health requires grease traps to be sited for easy maintenance access and for direct transfer of greasy waste to collection trucks, with vehicle access generally within 10 metres.
This diagnostic approach helps you get the right service, not an incomplete clean.
Step 2: Professional Cleaning Methods and Equipment
Our team uses practical, commercial-grade equipment to effectively clean traps. Depending on the size and installation, we may use suction tools, scrapers, buckets, pressure-flushing tools, absorbent products, and safe degreasing chemicals. We also use rubber gloves, PPE, and containment methods to maintain a controlled, hygienic work area.
During cleaning, we remove floating grease, settled sludge, oils, fats and food debris, then clean the walls, baffles and internal sections of the trap. Where accessible, we also flush the line from the trap to the connected system. This matters because grease traps are only one part of the overall wastewater path. If the trap is clean but the pipes remain coated with grease, the problem can return quickly.
The result is better flow, fewer odours, and a lower risk of damage to downstream sewers and plumbing systems.
Step 3: Maintenance Schedules and Long-Term Solutions
A one-off clean helps, but long-term performance depends on regular maintenance. The right cleaning frequency depends on your menu, cooking style, business volume, operating hours, water usage, and device size. A fried-food concept will usually require more frequent service than a light-beverage outlet. This is why there is no single standard interval that suits every premise.
That said, PUB recommends cleaning grease traps at food establishments at least once every 2 weeks, and cleaning or flushing the private sewerage system at least once every 6 months to eliminate grease accumulation.
We help you set a realistic maintenance rhythm so your grease trap, connected pipes and wider system stay workable, compliant and less prone to emergency call-outs.
Step 4: Grease Trap Cleaning vs Drain Clearing: Which Do You Need?
Trap cleaning and drain clearing are related, but they solve different problems. Grease trap cleaning removes accumulated FOG, solids and sludge inside the device. Drain clearing focuses on restoring flow in blocked drain lines, floor traps or connected pipes. Sometimes you only need one. In many food businesses, you need both.
If some of the grease build-up has already moved beyond the trap and into the line, simple cleaning will not fully solve the issue. In that case, we may recommend flushing, descaling or drain jetting as part of the solution. If the problem is still localised to the trap, a focused clean may be enough.
By checking the entire route from the kitchen discharge point to the accessible sewer line, we can recommend the most cost-effective approach for your business.

Pricing & Estimate Information
Our grease trap cleaning service is priced to stay accessible for both small outlets and larger commercial kitchens, with rates from $35, depending on the size of the trap, the amount of grease and sludge present, access conditions, and whether additional services such as flushing, drain clearing or line cleaning are needed.
We do not rely on vague pricing. Instead, we explain what the job involves, what affects cost, and what solution we recommend for your premises.
For example, a compact grease trap under a sink may require a simpler cleaning process than outdoor grease traps serving larger kitchens, food courts, or multi-tenant systems.
The cleaning frequency, site layout, materials, and the condition of connected pipes also affect the quote. To make things easy, we offer a free quote before work starts and a no-obligation estimate. Call 88661958 anytime for a fast assessment and a transparent service recommendation.
