Wainiha sits between Hanalei and Hāʻena along Wainiha Bay and the Wainiha Valley — a 2030 Act 125 priority zone with dense legacy cesspool inventory on parcels close to the river and shoreline.
Working on the ground in Wainiha
High water table near the Wainiha River mouth, heavy North Shore rainfall, one-lane bridge access limiting truck size, and SMA overlay across most coastal parcels.
What we run here
Cesspool-to-IWS conversions ahead of the 2030 deadline, drainage retrofits, driveway grading on valley parcels, and foundation excavation for rebuilds.
Your cesspool priority zone

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.
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.
