  2. Recommend pumper used to fill tankers at all fill site operations

  3. Using separate pumper to provide water supply maximizes flow from hydrant and eliminates need

      for tanker to deploy drafting equipment at static source in order to fill tank

  4. Use of pumper adds high degree of safety by controlling movement of water

  5. Driver must determine best position for drafting or hydrant connection that allows maximum access

      for tankers to be filled

      a. Pump panel located so driver can view both source and fill operations

      b. Apparatus with side-mount pump panels have pump panel away from water with intake and

         discharge hoses on opposite side, allowing driver to view tanker filling operations

      c. Front- and rear-mounted pumps require apparatus positioned in manner that does not obstructs

         driver’s view of tanker filling operation

      d. Each tanker filled at minimum rate of 1,000 gpm

  6. When positioning at hydrant, driver should connect large diameter intake hose between pump

       intake and steamer connection on hydrant

       a. If hydrant on particularly strong main, 3-inch lines also connected between 2½-inch hydrant

          outlet(s) and auxiliary intake(s) on pump

       b. Maximizes amount of water pumper able to flow to tanker being filled

  7. When positioning at draft, seek spot that requires minimum amount of lift or hard intake hose

       a. Maximizes amount of water supplied to tanker

       b. Number of discharge lines to tanker fill spot can be increased or lengthened

       c. Fill site pumper not necessarily located directly next to tankers being filled

  8. Static water supply sources completely inaccessible to pumpers

       a. In these cases, two or more high-volume portable pumps used to relay water to fill site pumper

          if less than 100 feet between source and pumper

       b. Fill site pumper may receive water from portable pump(s) in two primary ways

           1) First to hook discharge hose(s) from portable pump(s) directly into pumper’s intake


           2) Second method involves setting up portable water tank next to fill site pumper

           3) Discharge line(s) from portable pump(s) used to fill portable tank

           4) Fill site pumper drafts water from tank to fill incoming water tankers

  9. Regardless of whether hydrant or static source used small discharge line within view of driver

      continuously flowed from fill site pumper

      a. Ensures loss of prime does not occur during drafting operations

      b. When operating at hydrant, ensures pump overheating does not occur when discharge lines not

          being flowed to fill tankers

      c. When operating from static supply, discharge line should return water to source

C. Fill Site Layout

  1. Once fill site pumper positioned at water supply source, lay out remainder of hose and appliances

      needed to operate at fill site

  2. Assume that each tanker has two-inch direct tank fill connections or one LDH direct tank fill

      connection on rear of vehicle

  3. First thing is where tanker driver parks tanker when it arrives at fill site

      a. Positioned so minimum of hose required from fill site pumper

      b. Ideal fill position one that allows driver to enter from one direction and exit from another without

          need to turn or back up

      c. Position should allow room for empty tankers to line up and wait to be filled without creating

          traffic hazard

  4. Once exact fill spot established, traffic cone or similar marker used to denote stop-ping point for

       tanker driver

       a. Cone positioned on side of road or at safe spot in parking lot

       b. Tanker driver instructed to pull vehicle adjacent to cone at point where driver’s side door
