DEC 111979 BOOK 42 PAGE 25 the total adjusted flow against the design capacity of the plant, we established that the sewage treatment plant was 43% used and useful and that the remaining 57% would be held for future use. � As we now look at the sewage collection system, the following concepts were used to establish the used and useful portions for rate base. All force mains will be considered used and useful. The collection of mains will be considered on the basis of housing density with adjustment for the marginal reserve factor. To establish the dollar amount for the sewer mains we used the weighted historical cost for the various size mains. Housing density analysis is made by comparing the number of actual connections with the number of potential connections, for the test year we had 278 actual connections and 481 potential connections. This gives us a housing density percentage of 57.80. Now, when we apply the marginal reserve of 5.6% we have established a used and useful portion of the collection mains of -61.1% with the remaining 38.9% to be considered held for future use. The actual dollar values for the used and useful analysis are contained in Exhibit 4 (a). 10. Now, Mr. Vaughn with regard to the overall operation of the utility office and plant: a. (Q.) Have the plant and the facilities of the utility been maintained and operated by certified operators? (A.) Yes, both the water and sewer plants have been maintained and operated by certified operators, as outlined by the Department of Environmental Regulation.
