How do i get my alcoholic daughter out of my house?

My daughter is an alcoholic. During the past three years, I have tried everything to help her - paying for 3 months rehab, paying for a course of psychotherapy, letting her live rent free, paying her bills etc. but nothing stops her drinking and she is not capable of holding down any job. She is living on state istance (which all goes on booze). When she is drunk she is violent and abusive. I have got to the point where I can't stand it anymore and i want her out. I don't want to put her on the streets but I want her out.
