Mobile Home Park Well and Septic

[Chris Bruni]

I've been evaluating a couple of mobile home parks for sale near me, both with well and septic, both a couple miles outside of the nearest municipality.  Financials look very good (cap rates ranging from 12 -16%) and I'm OK with further evaluating those, but have concerns about aging infrastructure.  I have first-hand experience with well and septic systems for a private residence and know that there are requirements in my state to have them pumped periodically, but am curious about the tests that a MH park might have to endure.  Does the EPA or a similar state (Wisconsin) governmental entity test and report on private sewage systems like these?

Thanks in advance for any guidance!
