<strong>Systems</strong> <strong>Analysis</strong> <strong>of</strong> <strong>Zaragoza</strong> UWS<br />

Otherwise it won’t be possible to monitor the trends <strong>of</strong> the system towards<br />
sustainability.<br />
6.7 Priorities for urban water sustainability would be: 1) continuing on reducing<br />
water withdrawal and unaccounted for water, 2) optimizing energy consumption<br />
and its indirect impacts on atmospheric emissions 3) reducing phosphorus loads<br />
to the Ebro. The impact <strong>of</strong> heavy metals and other persistent pollutants also<br />
deserves attention since such impact is not necessarily linear to the scale <strong>of</strong><br />
loads. Storm water does not seem to be a major problem for <strong>Zaragoza</strong>, but the<br />
results presented here are not reliable enough. Further studies concerning this<br />
matter are required.<br />
6.8 Major drivers for water management in <strong>Zaragoza</strong> are population increase,<br />
National Policies on water and environment and climate change. Combined<br />
effects are expected to worsen problems <strong>of</strong> water management for <strong>Zaragoza</strong> in<br />
the future.<br />
6.9 <strong>Water</strong> from the new source, the Yesa reservoir will be able to fulfill <strong>Zaragoza</strong>’s<br />
water requirements during the next 50 years, even under worst possible scenario<br />
for climate change and irrigation. However in the future might experience some<br />
negative changes on water quality. Ebro River will be even more unsuitable for<br />
drinking purposes. Therefore <strong>Zaragoza</strong> will have to completely relay on the Yesa<br />
reservoir to fulfill its water demand.<br />
6.10 Comprehensive strategies to cope with such problems are to be set by all<br />
important stakeholders in <strong>Zaragoza</strong> and the <strong>SWITCH</strong> project would contribute<br />
with important initiatives to the process. The parameters presented here as<br />
sustainability indicators will contribute to assess the success <strong>of</strong> the set strategies.<br />
