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?
Not at all the video you’re referring to (probably), but my first thought was this wonderful gem.
