As a (now former) wastewater engineer, I'd take sanitary sewers over septic tanks anyday. With septic tanks you run into many more maintenance issues with things like clogging, overflowing, cleaning, etc. Not to mention this cost is borne onto the homeowner and not the municipality. There's also persistent groundwater issues. Even if you have good soil permeability and aren't impacting an aquifer, multiple septic systems can really start causing environmental harm on surrounding waterbodies. For many people, having sewerage isn't an option, but there's a good reason many municipalities are investing millions into moving their residents off of septic systems.
