Pyramid of New Water Sources
A conceptual breakthrough for thinking about how to meet our future water needs. Check out the Pyramid of New Water Sources, Jerry Yudelson’s new tool to show future water supply sources, a pyramid with ten steps of increasing cost and complexity.

The Pyramid of New Water Sources ranks the following measures:
- Changing behavior, with better information and codes
- Low-cost/no-cost measures, such as fixing leaks and lower water-using fixtures
- Irrigation measures, including native plantings and drip irrigation
- Hygiene, such as water-free urinals and low-flush toilets
- Appliances, such as water-conserving dishwashers and clothes washers
- “Extreme Makeovers” that include composting (no water) toilets, hardscape landscaping and onsite blackwater treatment and reuse.
- Water heating, one of the biggest energy users in the water cycle, including hot water recirculation loops and solar water heaters
- Onsite reuse, including rainwater collection and graywater for irrigation
- Offsite reuse, using reclaimed water from “purple pipe” systems and even “sewer mining”
- Desalination and new water sources, such as creating potable water with reverse osmosis treatment of reclaimed sewage
I think this is a great new conceptual tool. I’d like your thoughts.
