933.18 PAYMENT OF CHARGES.
   (a)   The sewage charges herein provided shall be payable monthly.
   (b)   The charges herein shall constitute the net charges for the sewage service if paid within a period of twenty days next following the date of billing. If paid after the ten-day period has elapsed, the applicable charges shall be at the gross rate, which shall be ten percent (10%) greater than the net charge, but in no case shall the additional charge be less than ten cents (10¢) .
   (c)   It shall be understood that the U.S. government postmark shall govern the due date and that when any payments are mailed within the ten-day period or paid at an authorized collection agency within the ten-day period, they shall be considered as paid within the prescribed time limit and exempt from penalty. In the collection of such payments by mail, the U.S. government postmark on the envelope containing the payment shall be identified and retained for a period of four months after which they shall be destroyed and the gross amount of such bill shall not be disputed.
   (d)   Each sewer charge established and made pursuant to these regulations is hereby made a lien upon the premises charged therewith, and if the same is not paid within ninety days after it is due and payable, it shall be certified to the County Auditor who shall place the same on the tax duplicate. With the interest and penalties allowed by law, it shall be collected as other municipal taxes are collected.
