I Don't Know What To Do! Help Me! Water?

I was in the bathroom to freshen up so I masturbated today and after that I wash my penis with water, but I felt like the sleeve of my hoodie touched my penis and since then I have been feeling that my semen is on my sleeve, since I checked there was nothing like that, after that I washed my hands and picked up the 20 liter water tank and put it in the cool cage and during the same time my sleeve touched the back part of the water tank, since then I have been feeling that my semen went into that water and I have committed a sin and my family members will drink that water,  what should I do now, I am feeling very nervous and uneasy! I can't tell this to my family members and also cannot throw a 20 liter water tank! Can someone pregnant by drinking that water?
