As shown below, significant savings <br />can be realized with the use of the Desalting Plant. Delivery <br />charges are virtually eliminated, power costs are reduced by <br />about 50 percent, and during years of desalting (60 percent of <br />years), the incremental labor costs are eliminated as only minor <br />work would be involved to discharge and monitor the supply to <br />Yuma. <br /> <br />By proportioning the Desalting Plant operating costs to account <br />for the 40 percent/60 percent split in operations the operating <br /> <br />29 <br />
