Excavation in Hāʻena
Hāʻena sits at the end of Kūhiō Highway on Kauaʻi's North Shore, an area with legacy cesspools near the coast and Limahuli watershed. Under Hawaiʻi Act 125, every cesspool in the state must be converted, upgraded, or connected to sewer by January 1, 2050.
Working on the ground in Hāʻena
Saturated coastal and alluvial soils, one-lane bridges limiting equipment size, frequent road closures from rain or surf, and strict SMA (Special Management Area) review on every job near the shoreline.
What we run here
Cesspool-to-IWS conversion site work, elevated foundation pads, drainage and french-drain installs, and limited-access excavation on end-of-road parcels.
Planning urgency categories near Hāʻena
The Hawaiʻi Department of Health groups cesspools into planning urgency categories based on proximity to drinking water, streams, the coastline, and sensitive ecosystems. These categories help homeowners and agencies decide where to convert first. They are not legal deadlines for individual properties.
A planning urgency category (not a legal deadline). These systems are generally closest to drinking-water sources, streams, wetlands, or the coastline, so the Hawaiʻi DOH prioritization tool flags them to plan first.
The only enacted statewide cesspool deadline under Act 125 and HRS 342D-72 is January 1, 2050. Priority 1 and Priority 2 are planning urgency categories, not legal deadlines or property-specific determinations. For your parcel's category, consult the Hawaiʻi Cesspool Prioritization Tool or the DOH Wastewater Branch.
