The best fit cost curve is y= $4.3975x 0.7491 ; this has an R 2 correlation of 0.9981. Note this<br />

equation estimates the capital construction cost (in millions of 2007 dollars) excluding the<br />

impact of escalation. Escalated cost is a more accurate representation of future project costs.<br />

This curve is statistically valid over a range of 60-170 mgd.<br />
