The valves originally designated to isolate the filters are failing to retain water from each filter while the work is being performed. The inability to retain water from the filters has created an issue with the removal of the old media and the installation of the new media and the new air grid air scour system. Both processes require the media to remain dry in order for proper disposal and installation. The addition of 2" drains to Filters 1, 2, 3, 4, 5, and 6 will help keep the water off the media for proper removal and installation. LEM Construction Is also replacing the inlet and outlet valves on the Ground Storage Tanks damaged during the February 2021 Freeze events (Storm Viola and Uri). The valve F from the High Service Pump Station is experiencing valve closure failure. A 48" Line stop will help isolate the outlet valve of Tank B for removal and replacement.
