I have contacted to the local department of environmental quality and they advised me that they could come and visually inspect the park and give a letter of compliance but that it is in effect worthless. They said things could change tomorrow. They cant guarantee how long a septic system will last. I asked if a septic inspection would help and they advised that either the system is working or its not and its a waste of time and he would not suggest it. They have stated it is a creeping failure and proper maintenance is the key and no inspection is going to give me that piece of mind or insurance. The department had records of a few violations in the last 30 years and they were repaired by adding more drain field line. The department stated they will work with landlords to allow them to repair septic systems and its very rare than a system can not be repaired.
The department stated the owner has been on top of it or there would of been more complaints or repair permit requests.
I have called a few septic inspection companies and they all say to inspect 35 tanks would be a waste of time and money and if there has not been issues in the past or recently that its unlikely to uncover anything. They said the only way to really inspect would be to pump all 35 tanks and then still they will not get into the drainfields because they do not want to disturb a functioning drainfield.
I have talked to the septic company currently maintaining the park and he has not had any issues since he has taken over pumping 5 years ago. He stated they are on a pumping schedule depending on usage.
The cost to dig up and pump a tank is around 300 per tank x 35= over 10k. That 10,000 could be put into a reserve for actual septic problems down the road. From everything I have read, I should have every last inch of septic inspected. However, what am I expecting to uncover? I don't see the owner doing anything unless it was apparent there is an issue with a septic tank or drainfield. If it was something critical it should be obvious or would of been in the environmental department records?
I am kind of lost at this point regarding getting a septic inspection. What should I do here?
