Excavation in Wailua
Wailua is the river corridor between Kapaʻa and Līhuʻe — one of the densest legacy cesspool zones on Kauaʻi, with parcels that sit right on top of the Wailua River and its tributaries.
Working on the ground in Wailua
Very high water table along the Wailua River and Opaekaʻa, soft alluvial soils that fail percolation tests near the bank, and SMA + cultural review near every coastal and riverfront parcel.
What we run here
Cesspool-to-IWS conversions ahead of the 2030 Act 125 deadline, raised drain-field designs for high water-table sites, foundation pads, drainage retrofits, and trenching for water and sewer runs.
Your cesspool priority zone
the hawaiʻi department of health classifies every cesspool on the island into a priority zone based on proximity to drinking water, streams, the coastline, and sensitive ecosystems. here is what shows up inside Wailua.
working target: convert by 2030
high-priority zone, these cesspools sit closest to drinking water wells, streams, the coastline, or sea-level rise zones. flagged for fastest conversion.
working target: convert by 2035
elevated-priority zone, close to sensitive water sources but not at the highest exposure tier.
2030 and 2035 are working targets recommended by the hawaiʻi cesspool conversion working group and reflected in kauaʻi county's grant prioritization. the only deadline in current law is january 1, 2050 under act 125. zone assignments are read from the doh prioritization tool.
