Overall the plant appeared to be maintained and operated very well. There are many upgrades and replacements taking place at the WWTP. Many new pumps and drives have been installed in the last year or two. The SCADA system has been updated recently. A new 15 MGD tertiary filter is currently being constructed. A new backup generator is in the process of being installed and it should be finished by Labor Day 2019. It's planned that the generator will be run one hour each week as a test. The upgrades that have taken place at the Hendersonville WWTP, along with the planned upgrades to come, are preparing the WWTP for an expansion of their designed/permitted flow. NC0025534 17 (Cont.)
