IWS, Septic Tank, Aerobic Treatment Unit
APTA will develop a plan for your Individual Wastewater System (IWS) on O‘ahu, Maui, Hawai‘i Island / Big Island, or Moloka‘i.
Our process includes site evaluation, proposal of environmentally-responsible wastewater treatment system, engineering drawings, and handling the permitting process for the Hawai‘i Department of Health (DOH) IWS Permit.
The State of Hawai‘i has currently approved septic tanks, aerobic treatment units, passive aerobic systems (e.g., Eljen, Presby), bioreactor gardens (e.g., Ridge to Reefs), composting toilets, and incinerator toilets as Individual Wastewater Systems (IWS).
