Following conversion to a mixed‐media filter bed using granular activated carbon for taste and odor control, the Appomattox River Water Authority in Petersburg, Virginia established a 2‐year filter changeover schedule. After trying several physical arrangements of the intake/out‐take eductor hoses and fire hoses used to supply water to the eductors, the final arrangement chosen was a PVC pipe placed through the wall, turned down on the outside of the wall, and run down to within 4 ft (1 m) of the ground. Additional details of the modification are supplied.
