Why my urine smell like sewage in between water?

Infection?: Sounds like a possible urinary tract infection. Sometimes urine can smell foul due to foods we eat. Asparagus contains a sulphurous compound called mercaptan (which is also found in rotten eggs, onions and garlic). When your digestive system breaks down mercaptan, by-products are released that cause the strange smell. When it's an infection usually you have burning or other complaints. Go see MD

Infection: is a good possibility so see your doctor and get checked.
