How do you fix land that doesn’t perk?
OPTIONS IF SITE FAILS. Even if your site fails a perc or deep-hole test, all is not lost.

How does rain affect a perc test?

Most commonly the lagoon is one of the most inexpensive types of systems (cheaper the better).
What kind of soil is best for a septic system?
