Septic and sewer systems are one of the most overlooked aspects of land investment. In this episode, I speak with civil engineer (and fellow land investor) Mitch Klein. We delve into everything you need to know about perc testing, soil types, engineered septic systems, sewer access, and all the hidden dangers that could destroy your business.
If you’ve ever asked, “Can I put a septic system in here?” or “What happens if the perc test fails?” this episode is for you. Mitch discusses key red flags, cost estimates, jurisdictional pitfalls, and even how wastewater treatment actually works. This is essential information for anyone planning to build on virgin land.
