The essentials

How often does a Corpus Christi restaurant need its grease trap cleaned?

Texas rules give you two triggers, whichever comes first. Pump when grease and solids reach 25 percent of the total liquid depth, or at least once every 90 days. Most Corpus Christi kitchens with an indoor 40 to 100 gallon trap land on a 30 day cycle because that 25 percent line arrives long before the 90 day calendar does. High volume seafood and fry houses on Water Street or Padre Island often run every two to three weeks.

What is a trip ticket and why does it matter?

A trip ticket is the transport manifest a registered grease hauler fills out for every load. It records the generator, the volume removed, the date, the transporter registration number, and the permitted disposal site that accepted the waste. If an inspector asks how your trap was serviced and where the grease went, the trip ticket is the answer. Keep them on site, and make sure you get a signed copy before the truck pulls away.

Should the whole trap be pumped, or just the top skimmed?

A proper service pumps the whole trap. Skimming means vacuuming the floating grease cap and leaving the water and the settled solids behind. It is faster, it is cheaper for the hauler, and it is the single most common way Corpus Christi kitchens get shorted. A proper service removes all contents, scrapes the walls and baffles, back flushes the inlet and outlet, then inspects the baffle for damage before refilling with clean water.

My trap is backing up right now. How fast can you be here?

Send the form with your address, trap size if you know it, and what you are seeing. Say it is an emergency in the first line. A backed up trap in the middle of dinner service is a health department risk, a slip risk, and a possible sewer overflow, so it should not wait for the next routine route day.

Are enzyme or bacteria additives a substitute for pumping?

No. Additives emulsify grease so it passes through the trap instead of being captured. That is the opposite of what a trap is for. The grease does not disappear, it moves downstream into the city collection system where it hardens. Additive use is not accepted as a substitute for mechanical cleaning. Pump the trap.

What does grease trap cleaning cost in Corpus Christi?

An indoor under sink unit in the 20 to 100 gallon range typically runs about 150 to 500 dollars per service. An outdoor in ground interceptor from 500 up to 2,000 gallons typically runs 300 to 1,500 dollars or more, driven by gallons pumped, access, and how long since the last full service. Send the trap size to get a price before any work starts.

How long does a grease trap cleaning take in a working kitchen?

An indoor 40 to 100 gallon under sink unit is usually 30 to 60 minutes door to door. An outdoor in ground interceptor between 750 and 1,500 gallons runs 60 to 120 minutes depending on how much solid has set up on the bottom and whether the lid opens cleanly. Most Corpus Christi kitchens book service between the lunch push and the dinner push, or early before prep starts.

Do I have to shut the kitchen down during the work?

No. You need to stop putting water down the lines that feed the trap while the tank is open, which in practice means the three compartment sink, the mop sink, and any floor drains tied to it. Cooking, plating, and service on the other side of the kitchen carry on. If your trap is under a prep station, you should be told which station to hold before anything is opened.

Can a trap that has not been serviced in over a year still be cleaned?

Yes, and it helps to say so up front. A neglected trap has a hardened grease cap and a compacted solids layer that has to be broken up and worked out, which takes longer and sometimes needs water added to mobilise. It prices higher, but it is a one time catch up. Once you are on a proper cadence, routine visits go back to normal length and normal price.

Can more than one location be serviced on the same day?

Usually, yes. If you run several restaurants around Corpus Christi, ask for them to be built into one route day so you are not chasing separate appointments across a week. Send all the addresses and trap sizes at once to get the group priced.

Scheduling and access

How much notice do you need for a routine clean?

For a routine visit anywhere in Corpus Christi, a few days is usually enough, and less than that is often possible. For island sites through the summer peak, for large interceptors that need a bigger truck, and for anything in hurricane season, book further out. The one time notice genuinely matters is when a named storm is in the Gulf, because availability across the whole Coastal Bend collapses within hours of a watch being issued.

Can the work fit around my service windows?

Usually, yes. Most Corpus Christi kitchens book service early before prep starts or in the gap between the lunch push and the dinner push. For strip centre interceptors on SPID, an early morning or a quiet Sunday when the parking lot is empty is faster and safer for everyone.

Does someone from my team need to be on site?

Someone should be there to let the crew in and to sign, and ideally somebody who can stop the fixtures feeding the trap while the tank is open. Beyond that no supervision is needed. For outdoor interceptors with parking lot access the work can often happen with very little contact, as long as somebody is reachable and the lot is accessible.

What if my trap lid is blocked by equipment?

Mention it in advance. In kitchens where a walk in, a prep bench, or a new equipment run was installed over the trap lid, a genuine full clean is difficult or impossible until something moves. It is worth solving properly rather than accepting bad cleans indefinitely.

Coastal and seasonal

Why do you keep mentioning lid corrosion?

Because it is the single most Corpus Christi specific thing in this trade. Cast iron manhole frames, lids, and fasteners on outdoor interceptors within a mile or two of the bay corrode far faster than inland equivalents. North Beach, the bayfront, Padre Island, and Flour Bluff all show it. The consequences are a seized lid that doubles service time, a failed gasket that puts odor into a patio, and eventually a frame that is a genuine failure risk under vehicle load.

Should my interval change with the season?

On the island and the bayfront, almost certainly. A Padre Island restaurant doing several times its winter volume through the summer is effectively two different kitchens on one tank. Running tighter through the peak and stepping out in the off season is more accurate and usually cheaper than one flat schedule held all year.

What should I do about my trap before a hurricane?

Pump it, and call early rather than waiting for a watch. An empty tank refilled with clean water is a neutral object during a closure. A full one is a sealed container of decomposing organic matter about to lose power and airflow in coastal summer heat. Also check that outdoor lids are seated and secured, and get your service records photographed and stored somewhere that will not flood.

Paperwork and compliance

Should the hauler give me the manifest or keep it?

Both. The trip ticket should be completed and signed for every job, with a copy left on site before the truck departs and one retained by the hauler, so a lost copy can be resent. The volume removed goes on the ticket, which is what makes your records auditable rather than decorative.

How should I file my trip tickets?

One physical folder, kept on site, every ticket in date order with the most recent at the front. Add a single cover sheet listing tank size, tank type and location, current interval, and when that interval was last reviewed. That folder is the entire compliance system for most restaurants and it takes five minutes to set up.

Should I be told if my trap has a structural problem?

Yes, ideally with a photo. A cracked or missing baffle is the most common one and it is serious, because a trap with a failed baffle stops separating entirely and passes grease straight into your lateral. That is a plumbing repair rather than a pumping job, but you want it identified before a line blocks rather than after.

Does a grease hauler need to be registered?

Grease trap waste is a regulated stream in Texas and transporting it requires state registration. That registration number belongs on every manifest you receive, from any hauler. If you cannot find a registration number on your current tickets, that is worth asking about.
