In-Ground Gravity Interceptor Installation in Maili, HI
Larger restaurants and high-volume kitchens often need an outdoor gravity interceptor. These concrete or polyethylene tanks typically range from several hundred to over 1,500 gallons. We excavate, set the tank on a stable base, connect inlet and outlet piping and install manhole risers. Homes are commonly built on slabs or on post-and-pier foundations, and raised homes keep much of the plumbing exposed and easier to inspect. We plan excavation equipment around the ground conditions we find on site. A properly installed interceptor can go far longer between pump-outs than an indoor trap.

HKL Plumbing installs a wide range of reputable grease trap brands known for their durability and effectiveness. We work with leading manufacturers like Zurn, Big Dipper, Schier, and Rockford Separators, among others. Our team in Maili can help you select the best brand and model that fits your specific needs, budget, and local code requirements for your commercial kitchen.
Gravity Grease Interceptor Installation in Maili, HI
Gravity grease interceptors, or GGI units, are larger, typically located outdoors, and rely on the natural difference in specific gravity between FOG and water. These are common for high-volume commercial kitchens. Our team handles the involved excavation, concrete work, and plumbing connections required for proper GGI installation, maintaining compliance with all local Hawaii ordinances for waste management.
New Restaurant Build-Out Grease Traps in Maili
If you are opening a new restaurant, the grease trap is often a key part of plan review. We work with your architect or contractor to size the unit and show it on plumbing plans. We then install it during rough-in so it is ready for inspection. Getting the trap right early avoids costly changes after the slab is poured. We also coordinate with the city's pretreatment staff when they require a review.
Hydro-Mechanical Grease Interceptor Installation in Maili
Hydro-mechanical grease interceptors, often called HGI units, are compact and designed for indoor use, typically under a sink or on the floor.
