Long story but please read

So I’m 15 and my mom and step dad just split up and we (no Steph dad)are still staying in the rent house we all lived in together well when he moved out h started to do stupid things like cut our water off (his friend works at the water department) well this last time he cut our water off my mom went up to the water department to get it turned on and his friend that works there said that we need to home owners permission to turn the Water back on so they called the hoe owner and she said “do not turn the water back on I want them out of my hosue anyways because one of my friends is looking for a rent hosue so I can just give that one to her when they move out” WE HAVE 1 AND 5 YEAR OLD BABIES IN THIS HOUSE WITH NO WATER this has to be illegals right? You can’t just cut your renters water off just to get them out right?
