<br />r <br /> <br />3 <br /> <br />estimated to cost $2.25 per cubic yard or $10,900 <br /> <br />per acre of surface area. <br /> <br />.~ <br /> <br />~ <br /> <br />3. <br /> <br />As an alternative to the earth blanket, it was <br /> <br />assumed that a 20 mil flexible membrane liner would <br /> <br />] <br /> <br />provide the same protection. The liner would require <br /> <br />a subbase of 6 inches of sand to lay the liner on and <br /> <br />] <br />.~ <br />, <br /> <br />J <br /> <br />9 inches of earth cover over the liner to protect it. <br /> <br />The liner will cost approximately $0.20 per square <br />foot for materials and installation and the subbase <br /> <br />and earth cover will cost $2.00 per cubic yard to <br /> <br />place for a total cost of $12,700 per acre of sur- <br /> <br />] <br />~ <br />] <br />] <br />~ <br /> <br />, <br /> <br />] <br /> <br />face area. <br /> <br />4. <br /> <br />The pipeline from the lower diversion structure on the <br /> <br />Virgin River to the Purgatory Flat evaporation ponds <br />will be sized (24 inch diameter) to carry 12 cfs and <br /> <br />to flow by gravity. <br /> <br />Due to the difficulty of in- <br /> <br />stalling the pipe along the Virgin River for several <br />miles, the cost was estimated at $60.00 per foot for <br />a total cost of $3,000,000. <br /> <br />5. The cost estimate for the rest of the facilities <br /> <br />required to complete the project was taken from the <br /> <br />"LaVerkin Springs Uni t" Concluding Report, December <br /> <br />1981, prepared by the Bureau of Reclamation. <br /> <br />(' (, 'l r:' 8 ,') <br />"'~ ...,1 '- ,J ...- <br /> <br />~ <br /> <br />I <br /> <br />P6/L8 <br /> <br />CREAMER AND NOBLE ~N,.CONSUL TING ENGINEERS <br />
