(a) For residential contributors, monthly user charges will be based on the average monthly water usage during the months of January, February and March of each year. If a residential contributor has not established a January, February and March average, his or her monthly user charge shall be the median charge of all other residential contributors.
(b) For commercial and industrial contributors, user charges shall be based on water metered during the current month. If a commercial or industrial contributor has a consumptive use of water, or in some manner uses water which is not returned to the wastewater collection system, the user charge for that contributor may be based on a wastewater meter(s) or separate water meter(s) installed and maintained at the contributors’ expense, and in a manner acceptable to the city. The meter(s) shall be open and available for inspection and reading by an authorized city representative.
