Where the cost of the main extension has been paid by the property owner/authorized agent pursuant to TMC 13.05.330 and 13.05.430, the city shall thereafter, but for not longer than 10 years after the date said extension is originally connected to the city’s water system, collect from any water user connecting to such extension that fraction of the cost of such as approved by the city, as the number of front feet or acreage, or combination of the two held by said water user, bears to the total number of front feet or acreage, or combination of the two, which may be served by such extension as determined by the city at the time such extension is connected to the city’s water system. Such sums as are thus actually received by the city shall be paid by the city only to the property owner/authorized agent originally installing such extension, but the city shall in no way be obligated to assure that the property owner/authorized agent making such extension is paid the total cost thereof, nor to initiate any action or incur any expense to collect any sum to be paid to property owner/authorized agent; nor shall such refund be from any revenues derived from the sale of water. Where different property owners contribute to the making of the extension, such sums shall be refunded to such property owners pro rata according to the amounts which they severally contributed toward the extension and pursuant to the preceding plan. [Ord. 910 Art. 5, § 10, 2016; Ord. 878 Art. 5, § 10, 2015.]
