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.

Common Questions

Frequently Asked Questions

How often does a cesspool need to be pumped vs. a septic tank?

Cesspools typically need pumping every 1–3 years depending on household size, because waste accumulates faster without the treatment stage of a septic system. Conventional septic tanks average 3–5 years between pump-outs. We'll assess your specific system and recommend a schedule.

Are there regulations about cesspool conversion in Hawaii?

Yes. Hawaii has a state mandate requiring properties within 500 feet of state waters to convert cesspools to compliant systems by 2050, with phased requirements. We handle cesspool decommissioning and new system installation for properties going through the conversion process.

What happens if I don't pump my grease trap?

Grease overflow clogs the sewer lines downstream, which can cause sewage backup into your kitchen and result in fines and mandatory closures from the Health Department. Commercial grease traps should typically be serviced monthly to quarterly depending on volume.

Can you set up automatic recurring service?

Yes. We offer scheduled maintenance programs for septic, cesspool, and grease trap pumping so you don't have to track it yourself. We send reminders and handle the scheduling.
