After a long deliberation, the City Council approved the $15/month increase in the sewer rate to meet the new Federal mandate for a very stringent phosphorus limit on the water discharged by the sewer plant. The EPA and the Division of Water Quality for the State of Utah are requiring Payson City to upgrade the sewer treatment plant by 2020. The cost of these improvements is estimated between $15 and $17 million dollars and they have to be completed and working by 2020. That means construction will need to begin in 2018 and the design plans will need to be completed by 2017. Many other cities throughout Utah are also in the process of raising their sewer rates for the same reason.
