Septic Tank Installs

Working across Southern Idaho, we can install septic systems for new home construction and replace old systems.

In order to install a septic system, customers need to fill out the application from Southwest District Health or Central District Health (depending on which county you live in).  We’ve made it easy and included links below to each of these forms.  If you have questions, don’t hesitate to give us a call or send us a message.  We’re happy to help.
