Optimizing Use of Non-traditional Waters, Drought Proofing the Electricity System and Improving Snowpack Prediction
Water and Energy Solutions for California
Draft reports for each of the subtasks are under development.
1) Market characterization of non-traditional waters: finalizing assessment of sources of nontraditional waters including identification of water systems affected by drought, and providing a list of treatment technologies and associated energy costs.
2) Recycled water scenarios for direct potable reuse (DPR): Results show that switching to DPR could increase local treatment energy by a factor of 3 but using DPR to offset more energy intensive water supplies will result in a net savings.
3) Characterization of snowpack and snowmelt: results are ongoing and information sharing continues; the real-time snow-water-equivalent diagnostic models for the hydropower plants was completed.
4) High-volume water recover desalination: completed testing bench-scale membrane performance.
This project funds research to reduce the stress on current water infrastructure in California. Research includes: (1) development of high-volume water recovery desalination processes for non-traditional waters, (2) characterizing the potential for non-traditional water use in California, (3) development of recycled water scenarios for use electricity generators and direct potable reuse(DPR) to offset other water sources, and (4) improving the characterization of California's snowpack.
Implementation of project recommendations in the study could provide lower energy costs associated with the treatment of non-traditional waters.
By reducing energy costs associated with treatment of non-traditional water, the project could increase use of this currently wasted resource, especially near the generation source. This could reduce greenhouse gas emissions asso
This project could provide greater reliability by improving forecasting methods used to predict water resource availability for electricity generation.
