The document discusses how water utilities can reduce greenhouse gas emissions and costs through optimizing pumping operations. It notes that water utilities are large energy users and pumping accounts for most of their energy consumption. The Global Warming Solutions Act of 2006 (AB 32) sets emissions reduction targets for California. Adaptive optimization software can dynamically schedule pumps for maximum efficiency, reducing energy use by 6-9% on average across various utility case studies. This leads to significant cost savings and reductions in greenhouse gas emissions to support California's climate change goals.

7. Typical Power Use in Water Distribution Up to 95% of energy consumption is used for pumping

8. Pump Life-Cycle Costs Electric motors driving pumps are not necessarily efficient Purchasing decision lead by lowest up from cost, not efficiency
