Nothing downstream is being dosed while that light is on. ### Wet ground at the field edge Effluent surfacing at the downhill end of the field or at a trench end usually means solids have carried over from an overdue tank. ### No record since the last inspector If nobody can produce a dated pump-out receipt, the health inspector will treat the system as unmaintained regardless of how it looks. Last updated: September 17, 2026 [Alcovy Septic](https://septictankpumpinglawrenceville.com/) handles commercial septic pumping in Gwinnett County, along with Rockdale and western Walton, for the buildings that never got a sewer line: churches, daycares, offices, machine shops, farms, small strip centers and event venues. Roughly 27 to 30 percent of Gwinnett is still on septic, one of the heaviest concentrations in the country according to [Gwinnett County](https://www.gwinnettcounty.com/government/departments/water/get-educated/septic-tanks), and plenty of that is commercial property on large lots. A commercial system is not a house system with a bigger lid. It is usually more tanks, more pumps and more things that fail on the day you have the most people in the building. ## What happens on a commercial visit The crew starts with what is actually in the ground, not what the last contractor assumed. That means locating every lid on the property: the primary tank, any second tank in series, the pump or dose chamber, and the grease interceptor if the building has a kitchen. If lids are buried, [risers](https://septictankpumpinglawrenceville.com/septic-tank-locating-and-risers/) usually pay for themselves by the second visit, because digging time is charged on every trip. Every compartment gets pumped. Georgia requires residential tanks to be two-compartment with the first holding at least two-thirds of the volume ([Rule 511-3-1-.05](https://regulations.justia.com/states/georgia/department-511/chapter-511-3/subject-511-3-1/rule-511-3-1-05)), and commercial tanks are commonly two tanks in series on top of that. Pumping the first one and calling it done leaves half the solids in place. With the tank empty, the crew checks the inlet and outlet baffles, pulls and cleans the outlet [effluent filter](https://septictankpumpinglawrenceville.com/effluent-filter-cleaning/), and records sludge and scum depths. Those two numbers are what set your next interval. ## Your interval comes from flow, not bedrooms Residential advice is written in bedrooms. That measure is useless for a daycare or a fellowship hall, so commercial systems are designed and scheduled on estimated daily flow for the use type. Georgia’s design criteria put offices and factories at **25 gallons per person per day**, restaurants at **50 gallons per seat per day**, hotels at 75 gallons per guest and residences at 150 gallons per bedroom ([Georgia DPH](https://dph.georgia.gov/document/document/design-criteria-peak-sewage-flow/download)). Run the arithmetic and the picture changes fast. A 30-person office moves about 750 gallons a day. A 60-seat cafe is designed around 3,000. The same state document notes that restaurant wastewater is two to three times stronger than residential wastewater in oxygen demand and suspended solids, which is why food service clogs soil absorption fields faster even when the volume looks modest. A church is the opposite problem: near-zero flow Monday through Saturday, then a spike. Tanks sized for the spike sit under-loaded all week and still fill with solids, so the interval is set by measured sludge depth rather than a calendar habit. Our [pumping frequency guide](https://septictankpumpinglawrenceville.com/guide/how-often-pump-septic-tank-georgia/) covers how that measurement works, and the [cost estimator](https://septictankpumpinglawrenceville.com/tools/septic-pumping-cost-estimator/) gives you a residential baseline to start from. ## What a commercial system has that a house doesn’t **More tank volume, often split.** Two or three tanks in series, sometimes 2,000 to 5,000 gallons each. Each has its own access and its own sludge profile. **A pump or dose chamber.** Flat or clay sites usually dose the field with a pump on floats rather than relying on gravity. That chamber needs pumping too, and a failed float looks exactly like a full tank from inside the building. **A grease interceptor.** Any building with a commercial kitchen has one ahead of the tank. It is a separate vessel on a separate schedule — see [grease trap pumping](https://septictankpumpinglawrenceville.com/grease-trap-pumping/) for what that service involves and how often it is expected. **An aerobic treatment unit.** On tight clay lots where a conventional field would not perc, the permit often required an ATU. Those have blowers, media and a maintenance contract behind them; [aerobic system service](https://septictankpumpinglawrenceville.com/aerobic-septic-system-service/) is its own visit. **Long runs of pipe.** Commercial buildings put more distance between fixture and tank, which is where grease, sludge and pine and water oak roots collect. When the tank is empty and the building still drains slowly, the line is the problem and [septic line jetting](https://septictankpumpinglawrenceville.com/septic-line-jetting/) is the tool. ## Records the inspector actually asks for A health inspector reviewing a food service or childcare property will ask when the system was last serviced and want a document, not a memory. Every visit should leave you with the date, the company, the gallons removed, the tank size, what was found and where the septage went. Keep them together in one file on site. The same records support a [Gwinnett stormwater fee credit](https://septictankpumpinglawrenceville.com/guide/gwinnett-stormwater-credit-septic-pumping/) — the county allows a 10 percent credit for five years on a dated receipt from a licensed hauler — and they are the first thing a buyer’s [inspection](https://septictankpumpinglawrenceville.com/septic-tank-inspection/) will request if you ever sell the building. ## What it costs Published local pricing is written around houses. [Homeyou’s June 2026 data](https://www.homeyou.com/ga/septic-pumping-lawrenceville-costs) puts a standard Lawrenceville-area pump-out at **$280 to $520**, with a full observed range of $196 to $789. Commercial work scales from there on volume, tank count and access, and after-hours work typically carries a 50 to 100 percent premium. One cost driver is not obvious from the outside: disposal. Gwinnett charges **$130 per 1,000-gallon ticket** for septage at its receiving sites in the 2026 [DWR fee schedule](https://www.gwinnettcounty.com/documents/d/gwinnett-county/dwr-rates-fee-schedule-2026), so a 5,000-gallon property carries real disposal cost before a truck moves. You hear the range before anything is scheduled. Our [Lawrenceville pumping cost guide](https://septictankpumpinglawrenceville.com/guide/septic-tank-pumping-cost-lawrenceville-ga/) breaks down the residential baseline. ## Who is allowed to pump it In Georgia, septic tanks must be pumped by a certified pumper working for a company that holds a county septage removal permit, per the [Georgia Department of Public Health](https://dph.georgia.gov/environmental-health/onsite-sewage/how-become-certified-installerpumper). Certification requires passing an exam with a score of at least 70. Ask for both — the individual certification and the company’s county permit — before anyone opens a lid. The [vetting guide](https://septictankpumpinglawrenceville.com/guide/who-can-pump-septic-tanks-georgia/) explains what to ask for. ## The US-29 corridor Commercial septic clusters where older commercial zoning outran the sewer. The [Lilburn](https://septictankpumpinglawrenceville.com/service-areas/lilburn/) stretch of US-29 is the clearest example in our area: 1960s to 1980s buildings, some of the oldest tank stock in Gwinnett, and enough businesses searching for commercial septic tank services in Lilburn GA to show up in the keyword data. The same pattern runs through [Snellville](https://septictankpumpinglawrenceville.com/service-areas/snellville/) along US-78 and out into [Loganville](https://septictankpumpinglawrenceville.com/service-areas/loganville/), where Walton County has no sewer planned at all.

The process ## How commercial pumping works, _step by step_ 1. 01 ### Flow and site review We ask what the building does, how many people use it on a peak day, and what is already in the ground. That sets the tank volume in play and a first interval to test. 2. 02 ### Written interval and price range You get a service interval, a price range per visit and a scope that names every tank, chamber and interceptor on the property before anything is scheduled. 3. 03 ### Scheduled pump-out The crew pumps every compartment, checks baffles and filters, services the interceptor if there is one, and measures sludge and scum before closing the lids. 4. 04 ### Record and interval check You get a dated record for your file. If the sludge depth says the interval is wrong, we change it rather than repeat a schedule that is not matching the flow. Put your building on a schedule instead of a crisis. Tell Alcovy Septic what the building does and how many people use it, and you get an interval, a price range and a record you can file.

A small office of 20 people at Georgia's 25 gallons per person design flow moves about 500 gallons a day, while a 100-seat restaurant is designed at 50 gallons per seat. Most commercial tanks land somewhere between two visits a year and one visit every two years, and measured sludge depth settles it. ### Do I need a grease interceptor if my building is on septic? + If you cook, yes. Kitchen grease that reaches a septic tank floats on the scum layer, carries out of the outlet and blinds the drain field trenches. A separate interceptor keeps it out of the tank, and it needs its own pump-out schedule. See our grease trap page for how that service runs. ### Can you pump around our operating hours? + Yes, and for most food service, daycare and church properties that is the point. Work outside operating hours normally carries a premium of 50 to 100 percent over the business-hours rate, which is worth it against closing on a Sunday morning or a lunch rush. ### What records does a health inspector expect to see? + A dated record for each visit showing the date of service, the company, the gallons removed, the tank size, what the crew found and where the septage went. Keep them in one file on site. The same paperwork supports a Gwinnett stormwater fee credit application. ### Who is allowed to pump a commercial septic tank in Georgia? + A certified pumper working for a company that holds a county septage removal permit, under the Georgia Department of Public Health. Certification requires passing an exam with a score of at least 70. Ask any contractor for both before they open a lid on your property. ### Do you give a price before you start? + Yes. You hear a price range on the phone, and the crew confirms the final price once the lid is uncovered and they can see the tank. If anything changes the price, such as a deeper dig or a lid under concrete, they stop and ask before continuing.
