I’m spending a week in La Jolla, CA, USA, about 15ft above sea level and I’m wondering where the sewage goes? There’s no room between here and the sea for a treatment plant. There’s pretty big apartment complexes and hotels that would need enormous septic tanks. How does it work?
Don’t have the link handy, but there’s a video out there about Chicagos approach to this and it’s absolutely nuts. The amount of infrastructure they’ve put in place, and sewage still ends up in the lake.
Not at all the video you’re referring to (probably), but my first thought was this wonderful gem.
