Approximately 99% of the wastewater stream that enters a treatment plant is discharged as rejuvenated water. The remainder is a dilute suspension of solids that has been captured by the treatment process. These wastewater treatment solids are commonly referred to as sewage sludge.
At present, almost all sewage sludge produced in Pennsylvania has been treated and is of sufficiently high quality to be classified as biosolids. Somewhat less than half of this material is disposed of by landfilling or incineration, while the remaining biosolids are recycled to the soil by use in agriculture, mine reclamation, landscaping, or horticulture.
Dinosaurs, as a taxonomic group, have been around[10] for 230 million years, but their heyday was the mid-to-late Jurassic period. In this period, there were probably around 5 trillion kilograms of dinosaur alive at any given time.[11] (Today, there are probably only a few hundred billion kilograms of living dinosaur,[12] 50 billion of it chicken).
If we assume Jurassic dinosaur water requirements were similar to mammal ones,[13] then this suggests dinosaurs drank something like 1022 or 1023 liters of water during the Mesozoic era—more than the total volume of the oceans (1021 liters).
The average “residence time” of water in the oceans—the amount of time a water molecule spends there before moving into another part of the water cycle—is about 3,000 years,[14] and no part of the water cycle traps water for more than a few hundred thousand years. This means we can assume that, over timescales of millions of years, Earth’s water is thoroughly mixed—and dinosaurs had plenty of time to drink it all many times over.
This means that while the chances are that most of the water in your soda has never been in another soda, almost all of it has been drunk by at least one dinosaur.

“Rejuvenated” is a fancy way to say they dump it into the nearest water way (river, lake, ocean)
You’re mostly drinking water that has, at some point, passed through a dinosaur!
