BY-PASS / PUMP AROUND PROCEDURE:

TO BE PERFORMED AFTER INITIAL STAFFING AND EQUIPMENT

REQUIREMENTS HAVE BEEN DETERMINED:

• Position the pump at the structure or manhole to be pumped from.

      (consider hose routing vs. pedestrian/vehicle traffic impact) (picture # 1)

• Determine if containment is needed for break down/clean-up of by-pass.

(vac-con may be used to assist in clean-up if required)

• Determine the routing and footage requirements of the discharge hose.

      (consider hose routing vs. pedestrian/vehicle traffic impact)

·        Connect the basket strainer to the suction hose.

      (make sure to zip tie the cam-lock arms) (see picture # 3)

·        Connect the suction hose to the suction side of the by-pass pump.(see picture # 4)

• Carefully lower the basket strainer end of the suction hose into the structure or    

      manhole to be pumped from.

• Re position the pump if needed for best suction hose routing.

TO BE PERFORMED AFTER BY-PASS PUMP HAS BEEN POSITIONED

• Chock the tires of the pump trailer then lower the stabilizer legs. (picture # 2)

• Disconnect the tow chains and trailer wiring from the tow vehicle.

·         Uncouple the pump trailer from the tow vehicle.

·         Position the tow vehicle safely out of the way.

·        Place cones and/or barricades as needed for safety.

TO BE PERFORMED AFTER PUMP AND SUCTION HOSE ARE POSITIONED:

·        Position the discharge hose reel trailer near the discharge outlet of the by-pass pump. (see picture # 5)  Ensure tow vehicle has auto transmission.

·        Determine which cam lock fitting to be used on suction.

·        Connect the first section of discharge hose to the discharge of the by-pass pump. (see picture #6)

·        Start the auxiliary engine on the discharge hose reel trailer. (see hose reel S.O.P.)

·        Move the in/out lever to the out position to pay out the discharge hose. (see hose reel S.O.P.)

·        While paying out the discharge hose tow the hose reel slowly toward the discharge point.(see picture # 7)

TO BE CONTINUED AFTER A SECTION OF DISCHARGE HOSE HAS BEEN POSITIONED

·        Connect the next hose section or elbow and continue as needed and secure. (see pictures #8  )

·        When the discharge point has been reached secure the end of the discharge hose prior to energizing the hose. (tie off with rope, secure with sand bags, etc.)

·        Determine if containment is needed for break-down /clean-up after by-pass.

(vac-con may be used to assist in clean-up if required)

TO BE PERFORMED AFTER DISCHARGE HOSE HAS BEEN ROUTED AND SECURED:

·        After the discharge hose has been secured, start the by-pass pump according to the pump S.O.P.

·        After starting the pump, walk the length of the discharge hose to ensure there are leaks in the hose and/or cam lock fittings.(see pictures # 9 & # 10)

·        Slowly increase the by-pass pump R.P.M.’s (ensure there are no kinks or leaks)

·        Continuously monitor suction point and discharge points to ensure desired performance is achieved. (do not allow by-pass pump to run dry as damage will occur)

TO BE PERFORMED AFTER BY-PASS HAS BEEN COMPLETED:

·        If a suitable fresh water supply is available, purge the by-pass pump and discharge hose. (ensure that contaminated liquid drains to a suitable location.)

·        After required by-pass and/or purging have been completed, disconnect the discharge hose at highest point in the run and ensure that waste and water drain out to a safe location. (containment or vac-con may be required for clean-up)

·        Begin disconnecting the assembled sections of discharge hose and re-spool on the by-pass hose reel. (make sure to rewind hose on the appropriately marked section of the by-pass reel.) (see picture # 11)
