Recycling Treated Municipal Wastewater for Industrial Water Use

Pipeline Capital Cost
Appendix B
Reclaimed Water Transmission Main Capital Cost and Pumping Cost Analysis
Capital costs by distance are developed based on the unit project cost for pipeline and
distance of the industry from the wastewater treatment facilities (1-10 miles). Annualized
capital costs are also developed based on a 20-yr debt service and presented as a cost of
service, in $/1000 gallons. Regression analysis was performed to find the best fit line to
estimate pipeline capital costs for a given pipe length. Exhibit 2 provides the details of these
analyses for urban areas and rural areas.
Power Cost for Pumping
Annual power costs were developed for average flows of 1 to 30 mgd over transmission
lengths of 1 to 10 miles, based on the total friction head and a residual pressure of 40 psi. A
regression analysis was used to provide the relationship of power costs to flow for various
pipe lengths. Exhibit 3 documents the details of these analyses.
