be met by the customer in making an extension is necessary. The rules should cover ownership of the extension, who will construct the extension, further extensions from contemplated extensions, pipe sizes, location of the ex­tension, materials, and the extent of the extension, i.e. fire hydrants, service connections, and meters. 5. Proposed water main extension financing policy. The analysis of financing policy in California revealed that in the majority of cases, the utility and consumer share in the cost of making the extension. It is believed that this method of financing extensions is equitable and applies to the las Vegas Valley Water District. It was further determined that the District can invest approximately $2.20 per dollar of anticipated revenue per year in an extension. For an estimated average annual revenue of $75*00 per customer, the District could invest $165.00 per customer. If it is assumed that the average lot frontage in the area served by the District is 60 feet and the cost of a 6-inch cast iron main is $5*50 per foot, including fire hydrants, service connections, and valves, then the cost of the extension per customer is $165.00 if the area is totally developed. It is proposed that the customer would be required to advance the total cost of the extension. This would avoid large capital expenditures by the District and also provide interest free money to the District for financing the extension. It is recommended that a refund policy be adopted which would return to the extension applicant, a portion of the advance made by the applicant. Although it has been determined that the District can afford to invest approximately $165.00 for each new customer, it is believed that the refund should approximate that amount of money which was refunded under Rule 9 of -15- 2019-05-23 2019-05-23 http://cdm17304.contentdm.oclc.org/cdm/ref/collection/p17304coll5/id/74… 74171 74172.pdfpage /p17304coll5/image/74172.pdfpage
