About Our Honolulu Plumbing & Cesspool Company

Our Story

Built on O'ahu, for O'ahu

Alpha Omega Plumbing Inc was founded in 2014 with one goal: give O'ahu homeowners and businesses a plumbing company they could actually trust. Too many residents had experienced the frustration of no-shows, vague pricing, and work that didn't hold up. We set out to be different.

Over the past decade, we've grown into one of the island's most recognized plumbing companies — handling everything from simple drain clogs to complex trenchless sewer replacements, solar water heater repairs, and cesspool-to-septic conversions. Our team is fully insured, and trained on the specific challenges of O'ahu's aging infrastructure and coastal environment.

That local footprint matters: O'ahu's plumbing conditions are different from the mainland. Hard, mineral-heavy water accelerates corrosion inside tanks and pipes, coastal humidity and salt air wear down fixtures faster, and a significant number of older properties are still on private cesspools rather than municipal sewer. We've built our team's experience around exactly those conditions.

We're proud to serve every corner of the island — from Honolulu and Kailua to Pearl City, Mililani, Ewa Beach, and beyond. When you call Alpha Omega, you get a real answer, an honest estimate, and a plumber who shows up.
