   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 3.4)
   11. Check filter bag. (See Section 3.5)
   12. Reinstate filter bag and gully pit lids.

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


3.3.2   Hand Maintenance

Two people are generally preferred to maintain the units by hand. However for shallow
units and units which contain mainly leaf material (low overall accumulated weight), may
be cleaned by one person. Note additional personnel may be required for traffic
management purposes or for general safety.

The following steps indicate a safe and efficient method to clean the Enviropod manually
by hand:
    1. Open gully pit. (See Section 3.2)
    2. Place the lifting hooks in the lifting loops of the filter bag. (See Plate 17)
    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 18)
    5. Lift the bag clear of the stormwater pit. (See Plate 19)
    6. Position the bag over the truck or other collection vehicle, taking hold of the loops
        at the base of the bag. (See Plate 20 and Plate 21)
    7. Lift and empty the filter bag by holding the bottom lifting loops only. (See Plate 22)
    8. Completely empty the filter bag. (See Plate 23)
    9. Brush the filter bag with a stiff brush to remove bound sediment from the filter
        pores. (See Plate 24)
