Nev. Rev. Stat. § 318.230
1. To levy and collect taxes, the board shall determine, in each year, the amount of money necessary to be raised by taxation, taking into consideration other sources of revenue of the district, and shall fix a rate of levy which, when levied upon every dollar of assessed valuation of taxable property within the district, and together with other revenues, will raise the amount required by the district annually to supply money for paying:
(b) The costs of acquiring the works and equipment of the district and, when due, all interest on and principal of general obligation bonds and other general obligations of the district.
In the event of accruing defaults or deficiencies, an additional levy may be made as provided in NRS 318.235. The board shall identify separately the rate of tax which is levied pursuant to paragraph (a) and the rate which is levied pursuant to paragraph (b) and shall make such information available to the public upon request. The board shall not continue to levy a rate of tax pursuant to paragraph (b) after the cost to the district of acquiring the particular work or equipment for which the rate was levied has been recovered in full.
