➜ Grease Trap Cleaning

Renewable Water Resources requires a grease interceptor to be cleaned once grease and solids together exceed 25 percent of its liquid depth, and Spartanburg Water applies the same trigger or quarterly, whichever comes first. Degler Waste Services handles grease trap cleaning for commercial kitchens across Greenville, SC, including outdoor interceptors, under-counter units, restaurant floor drains, and sink lines. Traps are pumped and scraped rather than skimmed, and service intervals are matched to how hard a kitchen actually runs.

GREASE MOVES SLOWLY UNTIL IT DOES NOT MOVE AT ALL.

Warm fats leave a fryer, a dish pit, or a wok station as liquid and travel the line without complaint. Somewhere past the trap they cool, harden, and start narrowing the pipe from the inside. Nothing looks wrong for weeks. Then a floor drain backs up during a full dining room and the problem is suddenly everyone's.


A trap on a proper schedule catches that material where it can be pumped out cheaply, instead of where it has to be cut out of a line under pressure.

  • Full pump and scrape, not a skim
  • Outdoor interceptors and under-counter units
  • Service intervals matched to your volume
  • Scheduled around your service hours

➜ GREASE TRAP CLEANING

YOUR KITCHEN LINE IS ONLY AS CLEAN AS THE TRAP.

A grease interceptor works by slowing flow enough for fats to rise and solids to settle, leaving relatively clear water to continue downstream. That separation only happens while there is room for it. Once the grease cap and the sludge layer close in on each other, the trap stops separating anything and simply passes the load into the sewer line, where it belongs to you and to your sewer authority.

REWA AND SPARTANBURG WATER BOTH WATCH THE 25 PERCENT LINE.

Kitchens here discharge into systems with published limits, and both authorities enforce them. Spartanburg Water sets outdoor traps at a minimum of 1,000 gallons, caps them at 2,000, requires under-counter units cleaned weekly, and expects maintenance records kept for at least a year. We pump on a schedule that keeps you comfortably inside those requirements and leave you the paperwork that proves it.

WE HAVE SEEN WHAT A SKIPPED PUMP-OUT COSTS.

Kitchens stretch intervals when things are busy, and we understand why. What we have learned across 24 years of Upstate restaurant work is that the saving never survives the first backup. A closed dining room, an emergency jetting bill, a ruined evening of covers, and a sewer authority asking questions add up to far more than the service that was postponed. Which of those would you rather budget for?

WHY CHOOSE US FOR GREASE TRAP CLEANING.

Your kitchen keeps running

Service gets scheduled around prep and service windows rather than through them. Early mornings, late nights, and closed days all work, so a cleaning never costs you a covered table.

The trap is genuinely empty

Pumping the liquid alone leaves the hardened cap and the settled sludge behind, and the trap fills again within weeks. We remove all three layers, which is what restores your actual capacity.

Compliance stops being a worry

Regular service keeps grease and solids under the 25 percent threshold your authority enforces, and you keep the records. Inspections become paperwork rather than a problem to solve.

Odors leave with the grease

Traps holding months of rancid material vent into the kitchen every time the lid moves. Clearing it removes the source instead of masking it, which staff and customers both notice.

The interval fits your volume

A high-fryer kitchen and a sandwich counter do not need the same schedule. We set yours from how quickly the trap actually loads, so you are not paying for service you do not need.

One call covers the whole line

Interceptors, floor drains, sink lines, and the jetting that clears what has already hardened downstream all come from the same crew, so nobody is pointing at another contractor.

➜ WHAT WE CLEAN AND CLEAR

OUR GREASE TRAP WORK

Six services covering the entire path grease takes through a busy commercial kitchen, from the sink line and the floor drain out to the interceptor and the sewer lateral beyond it.

PUMPING

Grease Trap Pumping


Complete removal of the grease cap, the liquid layer, and the settled solids from outdoor interceptors and under-counter units. Walls and baffles are scraped so the trap regains full working capacity, not just headroom.

FLOOR DRAINS

Restaurant Floor Drain Cleaning


Floor drains take the runoff nobody plans for, and they clog with a mix of grease, food solids, and cleaning residue. Clearing them stops the slow standing water that turns a kitchen floor hazardous.

SINK LINES

Kitchen Sink Line Cleaning


Three-compartment sinks, dish pits, and prep stations all feed lines that narrow steadily with fat. Cleaning these before the trap keeps the load moving and stops backups at the fixture itself.

LINE JETTING

Restaurant Line Jetting


High-pressure water scours hardened grease off the pipe wall along the runs a cable simply bores through. This is the option once a line has been narrowing quietly for months rather than blocking suddenly.

SCHEDULED

Scheduled Grease Trap Maintenance


A standing interval built around your kitchen volume, with the visit booked in advance and the records kept. Removes the guesswork and the last-minute scramble when an inspection is announced.

SNAKING

Inlet and Outlet Line Snaking


Blockages sitting right at the trap openings restrict flow long before the trap itself is full. Snaking the inlet and outlet restores the path and shows whether the problem is upstream or downstream.

➜ THE WORD ON OUR WORK

WHAT OUR CLIENTS SAY.

Restaurant operators tend to review on two things: whether we turned up inside the window we promised, and whether the kitchen was usable the moment we left. Those are the two things a service call can genuinely ruin, so they are the two we plan around first.

➜ Common Questions

FREQUENTLY ASKED QUESTIONS.

Kitchen managers ask us the same set of questions, usually while standing over an open trap. Here they are, answered ahead of time so you do not have to.

  • How does a grease trap work?

    Wastewater slows as it enters, giving fats and oils time to float and solids time to sink. Relatively clear water in the middle continues to the sewer while the other two layers stay behind.

  • How do you know when a grease trap is full?

    Measure it. Grease and solids together reaching 25 percent of the liquid depth is the regulatory trigger. Slow drains, odor, and rising water in the trap usually mean you are already past it.

  • What happens if you don't clean your grease trap?

    The trap stops separating and passes grease straight into your lateral, where it hardens. Degler Waste Services gets emergency calls across Greenville, SC for exactly this, and the jetting bill dwarfs routine cleaning.

  • Can my staff clean the grease trap themselves?

    Small under-counter units can be maintained in house, and weekly attention helps. Outdoor interceptors need a licensed hauler, because the waste has to be transported and disposed of at a permitted facility.

  • What is included in professional grease trap pumping?

    Full removal of all three layers, scraping of walls and baffles, a check of the inlet and outlet, refilling with water where required, and a manifest documenting what was hauled away.

  • Are there chemicals or enzymes I can use to maintain my grease trap between cleanings?

    Additives emulsify grease so it flows past the trap rather than staying in it. That looks like a clean trap and creates a blockage further down the line, so most sewer authorities discourage them.

  • Why does my grease trap fill up within 30 days?

    Usually the trap is undersized for the volume passing through it, or a previous cleaning left the hardened layers in place. Degler Waste Services checks both on Greenville, SC kitchens before adjusting the interval.

  • Do all commercial kitchens require the same cleaning frequency?

    No. A fryer-heavy operation loads a trap far faster than a bakery or a coffee shop. Frequency follows your actual grease output, bounded by the quarterly minimum your authority may impose.

➜ HOW WE WORK 

FROM A FULL TRAP TO A CLEAR LINE, HERE IS HOW.

STEP 01

Look at the kitchen, not just the trap

We ask about menu, covers, fryer count, and the last service date. Volume and cooking style decide the interval far more than trap size alone does, and that is what sets an accurate quote.

STEP 02

Book around your service hours

Cleaning is scheduled for a window that does not touch prep or service. For most kitchens that is early morning or after close, and the timing is agreed before the truck is assigned.

STEP 03

Measure and open safely

The grease and solids depths are recorded before anything moves, so you have a number rather than an impression. Lids come off with the surrounding floor or ground protected against spillage, and the area kept clear of staff.

STEP 04

Pump and scrape all three layers

Grease cap, liquid, and settled solids all come out. Walls, baffles, and the floor of the trap are scraped clean, which is the difference between restoring capacity and simply making room for the next few weeks.

STEP 05

Check the flow path

Inlet and outlet are inspected while the trap is empty. If either is restricted we snake or jet it there and then, so the trap is not filling early because of a problem outside it.

STEP 06

Refill, document, and rebook

Your trap is refilled where required, the lid resealed, and the area washed down so the kitchen is ready to use. You get the disposal manifest for your records and the next service date set before we leave
