You are factually wrong that Victoria's sewage is untreated.  The final state of Victoria's treatment after source control, maceration and screening, is dispersion through deep undersea diffusion pipes into the oxygen rich, cold, saline marine environment, into an environment that flushes 8 billion gallons of that marine water past the diffusion  pipes twice daily with the tides.

San Diego has virtually the same system that Victoria has, with a population of over 1.3 million people.  San Diego appealed an EPA order for land-based treatment on the basis if its unique receiving environment and was granted an exemption.  It has received awards for it's sewage system.  https://www.sandiego.gov/mwwd/facilities/ptloma
