Las Vegas Has More Restaurants Per Capita Than Almost Anywhere — And More Grease Trap Failures
Las Vegas’s hospitality economy means the city is packed with food service operations at every scale: Strip megaresorts with industrial-scale kitchens, neighborhood Chinese and Mexican restaurants that have operated for decades, food courts in every major casino and mall, ghost kitchen warehouses in North Las Vegas, and a rapidly expanding fast-casual corridor along the major suburban thoroughfares in Summerlin and Henderson.
Every one of those kitchens produces fats, oils, and grease — FOG — that cannot legally enter the municipal sewer system without being intercepted first. That’s what a grease trap or interceptor does. And when it’s not maintained, it doesn’t just stop working quietly. It backs up drains, floods kitchen floors, and triggers the kind of Southern Nevada Health District inspection result that puts a restaurant’s operating permit at risk.
Drip Doctors is a licensed commercial plumber serving the Las Vegas Valley with grease trap installation, cleaning, repair, and compliance documentation. We understand the stakes for a food service operation — a failed grease trap during dinner service on a Friday night is not an inconvenience, it’s a crisis.
Grease Trap vs. Grease Interceptor: What Clark County Requires
The terminology matters because the regulatory requirements differ significantly.
Grease Traps (Indoor)
Indoor grease traps are smaller passive devices — typically between 35 and 100 gallons — installed directly beneath a sink or on the floor drain near kitchen prep areas. They use gravity separation to capture grease before it enters the drain line. Indoor traps are commonly specified for lower-volume operations: coffee shops, small delis, bars with limited food preparation, and concession-style outlets.
Because of their small capacity, indoor traps fill quickly and require frequent service — often every two to four weeks for active kitchens. Neglecting an indoor trap leads to grease bypassing the device entirely and accumulating in drain lines, which eventually causes a full blockage.
Grease Interceptors (Outdoor)
Outdoor grease interceptors are large precast concrete or fiberglass vaults buried outside the building in the parking lot or service area. Sizes range from 750 gallons to 2,500 gallons or larger for high-volume kitchens. A full-service restaurant with a hood system, fryers, and multiple prep sinks will almost always require an outdoor interceptor.
Clark County Environmental Health and the Southern Nevada Health District use a sizing worksheet based on your kitchen’s total fixture drain flow rate (gallons per minute) and a retention time factor. Getting this calculation right at buildout prevents the expensive and disruptive process of replacing an undersized unit two years into operations.
Installation: New Restaurant and Tenant Improvement
For new restaurant buildouts or conversions of existing commercial space, grease trap or interceptor installation is part of the tenant improvement plumbing scope. Drip Doctors handles the full installation:
- Sizing calculation based on your kitchen plans and menu concept
- Permit submittal with Clark County Building Department and coordination with SNHD plan review
- Excavation and vault placement for outdoor interceptors (we coordinate excavation)
- Connection to kitchen drain lines and sewer lateral
- Access riser installation for easy future pumping
- Inspection and documentation for your certificate of occupancy file
We install both concrete and fiberglass interceptors and have completed installations for independent restaurants, franchises, food halls, and ghost kitchens throughout the Las Vegas Valley, including the dense restaurant corridors along Rainbow/Flamingo in Spring Valley, Green Valley in Henderson, and Downtown Summerlin.
Pumping, Cleaning, and Compliance Service
Once installed, a grease trap or interceptor requires regular pumping by a licensed waste hauler — and in Clark County, it also requires documentation that your device was serviced and that the waste was disposed of at an approved facility. SNHD inspectors ask for service manifests during routine inspections.
Drip Doctors coordinates pumping through licensed grease waste haulers and handles the plumbing side of grease trap service: inspecting the device after pumping, checking inlet and outlet baffles, cleaning the pipe connections, and noting any structural issues that need repair. We can set up a recurring service schedule so you receive a reminder before your trap is due — rather than discovering the problem when your kitchen floor drain starts backing up.
When a grease trap fails mechanically — a cracked baffle, a damaged lid, a broken inlet connection — we repair or replace the affected components. For drain cleaning of the lines downstream of a grease trap that have accumulated FOG buildup, we use high-pressure hydro-jetting to restore full flow. If you’re concerned about the condition of your lateral between the interceptor and the city main, a sewer camera inspection gives you a clear picture.
For Las Vegas food service operators opening a new location, expanding a kitchen, or dealing with a compliance notice, call Drip Doctors for grease trap service that keeps you operating — and keeps SNHD off your back.
