, <br /> Because none of the 24 project components considered could individually meet future water <br /> demands,it was necessary to combine various project components into"portfolios of <br /> projects" to provide a long-term water supply solution.Each of the seven potential project <br /> portfolios included phased implementation of selected projects to meet the City's increasing <br /> water demands.Project phasing was based on meeting projected dry year water demands at <br /> least five years before the demand occurs. <br /> Figure 1 below shows the portfolio that was determined to best meet the evaluation criteria. <br /> The evaluation shows that the first project that should be constructed to meet near term <br /> water demand is the Prairie Waters Project.The Prairie Waters Project will put the City <br /> ahead of the demand curve for several years and provide"drought hardening" of the <br /> existing system. <br /> Platteville Project <br /> Platteville Exchange i,+, <br /> Brighton Gravel Lakes 1 d a yl V,•,, I 1 g1 ..a • 1i + <br /> 140.0 .'

Aurora Water will <br /> accomplish this goal using reusable effluent from its existing portfolio of decreed reusable <br /> water rights,supplemented by lawn irrigation return flows and junior water rights. <br /> 4 <br />
