I live in a mobile home that I own on a rented lot. Can My landlord charge me for a sewage back up that ended up to be in his line?

We had a bad rainstorm and had 12 " of standing water on my lot. There was raw sewage shooting out of the lid on the lift station directly behind my house. I started having a back up in my sinks, shower, and toilets. I called a plumber and they ran a snake through my clean out and said the blockage was beyond my lines !! The park manager told them to fix whatever needed to be done and send him the bill to get me back on line, which took them 10 days by the way !! Now he is trying to charge me for the repairs.
