Can I get Septic field insurance?

I am not familiar with this particular coverage, but that doesn't mean that it's not available somewhere! I would first ask your current agent if they offer an endorsement for your homeowners policy, or a separate policy for purchase. You may also want to review the warranty for your septic tank, to see if it covers any sort of below ground leakage.

I also recommend doing an internet search for "septic field insurance". I googled the phrase and came up with a few resources that you may want to investigate.

The Powderhorn agency insures oil tanks and septic systems: http://www.powderhornagency.com/ProSept.html I am not sure how good they are, but the do provide insurance.
