During fiscal year 2016, the Joint Water System experienced an unexpected failure of filters 8 and 9. Upon inspection of the failed filters, it was noted that both filters needed repair. Filter 5 was demolished in 2012 and the remainder of the work was put on hold due to taste and odor issues arising in 2013. The completion of filter 5 was grouped with the repair of filters 8 and 0 during fiscal year 2016. The reserve funds maintained by the System were used to fund the rehabilitation and refurbishment of all three filters.
The filter rehabilitation and refurbishment project is a continuation of a phased approach to upgrade the water plant process improvements and extend the useful life of all capital assets. Filters 1-9 have been completely refurbished with new underdrains. The refurbishment of filters 10 and 11 is currently underway with an anticipated completion date of summer 2017.
