Cesspool compliance,
excavation support.
Hawaiʻi state law requires every cesspool to be upgraded, converted, or connected to a sewer by January 1, 2050. We help you screen the property, run the excavation, and coordinate the path through Hawaiʻi's conversion process.
What's included.
Site Evaluation
Soil percolation, setbacks, cesspool location, and access review on your property.
SMA Screening
Special Management Area review for properties near the shoreline before design begins.
Engineering & Design
Sized septic or ATU design stamped for DOH submittal.
DOH Permitting
We file the IWS permit application with the Wastewater Branch and respond to comments.
Septic / ATU Installation
Tank set, drainfield install, electrical and controls for ATUs.
Cesspool Decommissioning
Pump-out, crush, and backfill per Hawaiʻi Administrative Rules.
Final Inspection
We meet the inspector on site and turn over the certificate of completion.
Property Restoration
Finish grading, topsoil, and proper exit so your yard looks like we were never there.
Kauaʻi Excavation operates as GroundUp Pacific Construction Inc.'s (HI Lic. #BC-37905) Kauaʻi excavation and site-work team — together we hold the license, pull the permits, and complete the work on island.
Built for your site, not a catalog.
Gravity Septic Systems
The standard conversion for most Kauaʻi homes where soil and setbacks allow — septic tank plus a gravity drainfield.
Aerobic Treatment Units (ATUs)
Required where lot size, soil, or proximity to water won't support a standard drainfield. ATUs treat effluent to a higher standard before dispersal.
Advanced / Alternative Systems
For sensitive sites — shoreline, high water table, or constrained lots — we design to whatever DOH approves for your specific property.
We don't disappear after install.
Scheduled Pump-Outs
Routine pump-out service to keep your tank in spec and protect the drainfield.
System Inspections
Periodic inspections, ATU servicing coordination, and documentation for resale or refinance.
Long-Term Care
We stay on island. After install, you keep one local point of contact for service calls, troubleshooting, and follow-up.
Permitting takes weeks. Install takes days.
Be honest with yourself about the calendar. Once engineering and SMA review (when applicable) wrap, DOH approval could take up to several weeks. Once the permit is in hand, our crew is typically on and off your property in a few days. The earlier you start, the more options you have.
If financing matters for your project, ask us — we'll point you to our private lending and federal-program referrals so cost isn't a blocker to getting compliant.
READY TO START YOUR CONVERSION?
Free site assessment, no obligation. We'll walk the property, flag any red flags, and give you an honest read on timeline and cost before you commit to anything.
