Granted, there may be extra costs involved, but what other solution is there besides changing the way sewage is treated?

The only solution, which is impossible, is to develop drugs that are metabolized into harmless waste products. Otherwise, to declare that human urine is a hazmat that must be collected and handled by certified carriers who will regularly collect it from every home and haul it to a central site where it can be properly neutralized before being disposed of in a lined landfill.

We also have a similar problem with hospital sewage for patients receiving radioactive drug treatments. The isotopes end up in the urine just as easily and therefore down the drain to the municipal sewage plant.
