The financial burden that a failed septic system creates can be pretty substantial for the majority of folks. The cost to put in a new title 5 compliant septic system can range from $10,000 to $50,000 or more depending on the soil conditions, water table and whether ledge is encountered.he last thing you want is a problem with your septic system! As a Massachusetts Realtor who is involved in numerous few home sales it always amaze me how some sellers are so lackadaisical about getting their title 5 inspection taken care of prior to putting their home on the market.
