Septic Systems & Wastewater Planning

Many properties on Kaua‘i rely on septic systems rather than public sewer infrastructure. Hawai‘i’s cesspool conversion mandate is also requiring many property owners to evaluate wastewater upgrades and replacement systems.


Papa'iki Engineering Inc. provides septic and wastewater planning focused on:

Cesspool conversion support
Site-specific wastewater solutions
Drainage coordination
Infrastructure planning
Permitting support

Early coordination helps reduce delays during review, permitting, and construction.
