Start with separated sewage/wastewater and stormwater drains. Then accredited and highly scrutinised wastewater treatment and discharge into water bodies (or see below for a high-tech solution). As for clean water to the home, direct those stormwater drains to new reservoirs which sustain freshwater aquatic life. Protect aquifers from over-drainage, and build pipelines from water-abundant regions to water-scarce regions.
To reclaim waste water or treat unknown water sources back to potable/semiconductor standards we have ultrafiltration, reverse osmosis, UV treatment, pH adjustment, fluoridation, desalination, softening (which is generally obviated by RO...). This is basically Singapore's NEWater.
Good sanitation is a financial and political problem. The engineering has been solved for decades now.
You just want all your little worker bees to be in massive towers like Hong Kong, without a chance to even grow their own vegetables or have any private space?
I'm not sure if you realize this, but there are a lot of housing options in between suburban sprawl and high-rise apartment buldings. Like townhomes, rowhouses, duplexes, low-rise apartments, or even single family homes built more closely together.
Should everyone have a hydroponics room? Even a basic amount of veggies generally require more land than townhomes, rowhouses, duplexes, low-rise apartments can provide.
??? We don't need any AI for this.
