Field notes
The calculator asks for island, bedrooms served, current system, likely sewer access, and known site constraints. Its cost explainer groups work into engineering and design, system and materials, and construction and site work, while declining to assign statewide dollar add-ons for conditions such as rock or groundwater. A separate assessment request prepares an email and asks for contact details; the form says the request may be shared with an appropriate Hawaiʻi-licensed professional.
