In-Ground Gravity Interceptor Installation in Wailuku, HI
Larger restaurants and high-volume kitchens often need an outdoor gravity interceptor. These concrete or polyethylene tanks usually 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. Some valleys and lowland areas have clay-rich soil that swells with heavy rain and can stress slabs, foundations, and buried pipes. We plan excavation equipment around the ground conditions we find on site. A properly installed interceptor can go much longer between pump-outs than an indoor trap.

Ensuring your restaurant's grease trap system in Wailuku, HI meets all local and state plumbing and environmental codes is crucial. HKL Plumbing is familiar with Hawaii regulations concerning FOG discharge and commercial kitchen waste. We guarantee that every grease trap installation we perform is fully compliant, helping you avoid penalties and maintain a clean, responsible operation.
