Town of Pulaski, Virginia Emergency Filter-04 Rehabilitation

The primary focus of this project consisted of the demolition of an existing, failed underdrain, in a single cell filter at the Town’s Water Treatment Plant. The existing underdrain was comprised of precast blocks with plastic inserts that had experienced catastrophic failure. After the demolition was completed it was determined that the existing concrete structure needed to be coated which was completed using Warren epoxy. A new AWI underdrain was installed with new filter media. The project also included modifications in the pipe gallery including the removal of old flow control measures and the installation of a new magnetic flow meter, valves and surge relief piping.
