At my office I am getting impure water in taps, it is the mixture of petrol and diesel, Color n smell of water is also same.i am not going to washroom which is effecting my kidney. today I tried controlling but I felt a drop came out of my penis so I check it and a drop was there, is it najis? also what to do in this situation ? as this water won't make najis things paak.

That water don't make things Pak. Also don't stop going to toilet its makrooh. Go to there and dry your self when u finish then if get water do tahaarat after, your cloths won't be najis
