What We Do
Wastewater Services We Provide
Every wastewater system has different needs — we manage them all.
Septic Tank Pumping
Regular septic pump-outs remove accumulated solids and prevent system failure. We completely empty the tank — not just the liquid layer — and inspect the baffles and condition while we're there. Recommended every 3–5 years for a typical household.
Cesspool Pumping
Cesspools require more frequent pumping than septic systems because there's no treatment step slowing accumulation. We pump residential and commercial cesspools across O'ahu and document service for state compliance records.
Grease Trap Pumping & Cleaning
Restaurants, commercial kitchens, and food service operations are required to maintain grease traps. We pump and clean grease interceptors on scheduled maintenance programs to keep you compliant with City & County requirements.
Holding Tank Pumping
Properties without sewer or septic connections use holding tanks that require regular pumping. We service all holding tank sizes and can set up automatic scheduled pump-outs so you never have to think about it.
Service Documentation & Compliance
Hawaii DOH and City & County require documentation for wastewater system service. We provide written records for every pump-out — dates, volumes, condition notes — for compliance and property sale records.
Emergency Pumping
Overflowing systems, sewage backup, and system failures are handled as emergencies. Our line is available around the clock for urgent wastewater situations that can't wait.
