My landlord has promised to fix the sewer pipes to our house. He has dug up the sewer line and has taken the line out, so the waste from the house and the toilets are going into a hole in the back yard and you can see the waste and toilet paper. Is this a health concern that I should be worried about with having animals and children playing in the backyard? How can I report my landlord with out any retaliation from my landlord?
