Septic installation FAQ

How much does a new septic system cost on Whidbey Island?

Most new systems run $10k–$60k+. It depends on soils, system type (gravity, pressure, or advanced treatment) and site access. We'll give you an itemized estimate once we see your design.

How long does a septic installation take?

It depends on the system and the site. Some installs wrap up quickly, while larger or more complex systems take longer. We'll give you a clear timeline with your estimate and keep you updated along the way.

Do I need a permit before you can install?

Yes. A new or replacement septic system needs a design and an approved Island County permit before installation. If you already have one, we can get started. If not, we can connect you with a designer and walk you through the process.
