Therefore, the remainder of the analysis will focus on Bullet 2. <br />The evaluation of alternative transmission alternatives included: <br />- The ECCV Northern System <br />- Aurora's Prairie Waters Project (PWP) system <br />- Dedicated SMWSA transmission system <br />The PWP is expected to be online in 2010. The attractiveness of this alternative would be <br />dependent on sharing/allocation of capital, and operations and maintenance costs, operational <br />terms, peak off-peak deliver schedules and quantities, raw versus treated water deliveries, <br />inclusion/exclusion ofwater rights and other details. Due to these significant uncertainties this <br />alternative was screen from detailed cost analysis. <br />8 <br />
