Why Septic Systems Matter in Hawaii

Hawaii’s unique geography and climate make septic systems an essential part of many residential areas. With limited access to municipal sewage systems, septic systems provide an alternative solution for wastewater disposal. However, improper installation, maintenance, or design can lead to environmental hazards and costly repairs.

Key Cost Considerations

  • System Upgrade: Upgrading or replacing a septic system can cost between $5,000 to $15,000 or more, depending on the system type and size.
  • Regular Maintenance: Regular maintenance, such as pumping and inspections, can cost between $100 to $500 yearly.
  • Repair Costs: Repairing or replacing damaged or faulty components can add up quickly, with costs ranging from $1,000 to $10,000 or more.

Understanding Hawaii’s Septic System Regulations

To ensure your septic system complies with state regulations, familiarize yourself with the Hawaii Department of Health’s (DOH) guidelines. The DOH regulates septic systems through the Hawaii Administrative Rules (HAR) and the Hawai’i Register.
