Appendix D Technology Cost Curves Technologies and Costs for Control of Microbial Contaminants and Disinfection Byproducts D 1 June 2003 Appendix D Unit Costs Graphs Costs for independent flows are presented in the main text of this document. This appendix provides graphs of those points and displays the lines that were used to predict costs for flows other than those costed. This appendix provides the following information:

° Capital unit cost estimates for a wide range of design flows ( in tabular and graphical forms) ° O& M unit cost estimates for a wide range of average daily flows ( in tabular and graphical forms)

The range of design and average flows is intended to cover all possible system flows. When flows fall in between the design or average daily flows used to estimate unit costs, straight line interpolation can be used to estimate the capital or O& M cost. Design costs were calculated for points ranging between 0.007 MGD and 520 MGD. For plants with flows less than 0.007 MGD the value for 0.007 MGD was used. For plants with flows greater than 520 MGD, the costs are calculated by extrapolating a straight line between the last two calculated cost points. Points are included in the graphs at 0.0001 MGD and 1500 MGD to show these assumptions. Likewise for average daily flows, points were calculated between 0.0015 MGD and 350 MGD. Points outside this range show the assumptions used to extrapolate costs.

The Appendix D Contents ( shown on the next page) describes the exhibits in this appendix. Each exhibit lists the constraints and design criteria for the technology, presents a table showing the unit cost estimates for each design or average flow point, and graphically displays each point to illustrate the way in which the costs increase with flow. All graphs are in Log Log scale.
