Research Questions
What is impact of climate change on Salt Lake Citys water supply system performance?
Future reliability and vulnerability of SLC water supply system?
What impact will Rainwater Harvesting (RWH) have on SLCs integrated urban water system performance?

Cost Analysis
(5-year Period) (60-year Period)
-
SLCDPU Conclusions (so far)
Salt Lake Citys surface water sources show significant sensitivities to increasing temperature
Earlier runoff timing presents challenges in meeting late summer demands
Sources have different vulnerabilities
RWH can benefit broader IWRM goals
