% 4 4. That the prohahle cost of irrigation water is such that no revenue for defraying the cost of other facilities can he realized hy its sale. Therefore consideration of irrigation water is not included in this analysis. The following table shows the method of determining the cost of water per thousand gallons, based upon the assumptions set forth above and upon our estimate of the cost of construction of the facilities shown on the attached drawing: Cost per Cons. Cost Annual Cost 1000-gal $ $ $ Supply and Treatment (1) Plant 106,000 0.0175 Operation and Mainte­nance (incl. charge for water) 300,000 0.0495 Sub-total $406,000 ' 0. 0670 Transmission Eeservoirs and storage tanks 600,000 32,600 0.0054 Pipe lines 750,000 52,800 O.OO87 Pumps, etc. Operation and main- 50,000 6,000 0. 0010 tenance 25,000 0.0041 Pump 20,000 0.0033 Sub-total $542,400 0.0895 Distribution (2) System 600,000 42,400 0.0070 Operation and maintenance 20,000 0.0033 TOTAL $6o4,6oo 0.0998 Notes: (1) Based upon no initial cost for supply and treatment facilities. Annual cost shown is a sinking fund for replacement. If plant is purchased, the cost per 1000 gal. must be increased by $0,0C6 for each $1,000,000 of purchase price. (2) Cost for full distribution system for 1970 demand is estimated at $800,000. Cost shown is based upon average expenditure during period 1950 to 1970. - 7 -
