When collected the net amount, ascertained as provided in this article, shall be paid to the treasurer of the district, under the general requirements and penalties provided by law for the settlement of other taxes. The district may adopt the alternative procedure of tax collection and apportionment established by Chapter 3 (commencing at Section 4701) of Part 8 of Division 1 of the Revenue and Taxation Code and any amendments thereof; provided, however, that the district may thereafter abandon said alternative procedure at the end of any fiscal year of the
district.
