This study suggestion ties to VE I.1.10 (Proposal No. 2????). A bonded coating with EP is the best corrosion protection system for DI pipe if costs are not considered. Use of such a system would make DI pipe much more costly and steel pipe may become least cost pipe material in many sizes and pressure classes.  The Design Team should have soil investigations preformed (as discussed in their March 1995 draft report) and chose a recommended alternative. It is recommended that one or more qualified corrosion engineers assist the Design Team in this effort. It is recommended that the client be advised of the alternatives as well as advantages and disadvantages of each.(    PE alone without bonded joints (Original Preferred Option).       PE with Impressed Current CP (with bonded joints).      PE with Sacrificial Anode CP (with or without bonded joints).G" G"     Bonded coating with Impressed Current CP (with bonded joints).'% '%   G"  Bonded coating with Sacrificial Anode CP (with or without bonded options).( ( %0*0*0*  '%  Imported sand backfill of "Pipe Zone."    0   Evaluate the use of steel pipe as an alternate to DI pipe. $3,000 for study. Potential significant savings in bids.  Experience during the 1980's on the Southwest Pipeline Project in North Dakota and the WEB Rural Water Project in South Dakota indicates that steel pipe may be cost competitive with DI pipe in 24 and 30inchdiameter (and possibly even smaller diameters) if cathodic protection of DI pipe is provided. Steel pipe is available from a company in Denver, Colorado. DI pipe would probably come from Birmingham, Alabama, thus, transportation costs may make steel relatively more competitive on the Mni Wiconi Project. However, pressure class DI pipe was not available at the time of the aforementioned projects and its availability makes DI pipe more cost competitive. Steel pipe is available with rubber Oring joints. CP System costs (initial and O&M for steel pipe are significantly lower than for DI pipe. Information on CP System costs for steel pipe has been provided to the Design Team. Information on construction costs of 12 through 36inchdiameter DI pipe and steel pipe has been provided to the Design Team. H0*A"A" 0 H   Modify LifeCycle Cost (LCC) model used to evaluate core pipeline transmission system configurations to take into account variation in water use over life of project. 500 40 modify model. Potential significant savings in LCC due to better alternate evaluation and selection.  Design Team and VE Team LCC models both determine present worth of pumping energy costs based on pumping flow for design population every year. It is understood that the current population to be served is only about half the design population. Thus, because of the exponential relation between flow and headless, energy consumption would be well under half in the early years of the project. Because early year dollars do not discount nearly as much to present value as later year dollars do, the reduction in calculated pumping energy cost would be significant. It would be necessary to develop an estimate of the growth rate of water use to implement this proposed change.  This change in the LCC model would be necessary to evaluate proposed additional item for study related to staging of pump sized installed in pump stations.H P    P P H   P P  8 8 P P    P P 8   P    X X    Z?X VEOTHER.STY 3'3'Standard3'3'StandardHPLAS4DA.PRSx  (  X   H X` hp x (#%'0*,.8135@8:
