I have a sincere mistrust of engineering solutions for extending carry capacity. I can't blow-up a river, but I sure could blow up a dam. Or a water tower. Or a treatment facility. Leveraging technologies is called leverage because it puts one thing on the far end of a lever to effect great action. That relationship, over the long-term, is precarious. History books are full of stories of failed cities that leveraged a critical infrastructure that failed. Cities that over-extend their population on the back of engineered solutions find themselves hostage to a "right-sized" solution suitable 30-50 years in the past.
Sand hogs in New York and the trash carrier strike are cautionary tales. 80% of Los Angeles electricity is used to move water. Use of technology without redundancy and resilience is a disaster, it just may not have happened yet.
