    5.  If material has built up around the overflows, use the inductor hose to clear the accumulated material.
    6.  Remove filter bag from the pit.
    7.  Sediment retained in the gully pit grate is to be removed.
    8.  Back opening channels are to be cleared of any debris to ensure flow is not hindered. Debris can be
        collected using the inductor truck.
    9. All gully pit waste is to be removed from the pit.
    10. Check the Enviropod unit. (See Section 0)
    11. Check filter bag. (See Section 0)
    12. Reinstate filter bag and gully pit lids.




                          Plate 11 Cleaning an Enviropod using the inductor method

Gully pit sediments under no circumstances are to be backwashed into the gully pit.




    3.3.2 Hand Maintenance

The following steps indicate a safe and efficient method to clean the Enviropod manually by hand:
    1. Open gully pit. (See Section Error! Reference source not found.)
    2. Place the lifting hooks in the lifting loops of the filter bag. (See Plate 12)
    3. For extremely heavy and overfilled bags either use a hydraulic lifting arm to lift the bag, or remove
        excess material using a shovel or similar piece of equipment. IES prefers the use of a post hole shovel,
        due to the reduced strain on the back when digging and the ability of the shovel to grab material
        vertically. (Insert Picture)
    4. Lift the bag vertically off the supporting frame, ensuring that no undue pressure is placed on the filter
        bag. (See Plate 13)
    5. Lift the bag clear of the stormwater pit. (See Plate 14)
    6. Position the bag over the truck or other collection vehicle, taking hold of the loops at the base of the
        bag. (See Plate 15 and Plate 16)
    7. Lift and empty the filter bag by holding the bottom lifting loops only. (See Plate 17)
    8. Completely empty the filter bag. (See Plate 18)
    9. Brush the filter bag with a stiff brush to remove bound sediment from the filter pores. (See Plate 19)
    10. Check the filter bag. (See Section 0)
    11. Check the Enviropod unit. (See Section 0)
    12. Reinstate filter bag, ensuring bag is installed the correct way. (See Plate 20 and Plate 21)
