3.3 Cleaning methods
One of the following maintenance methods should be used for servicing EnviroPod Filters:


3.3.1 Cleaning using an inductor truck                                3.3.2 Hand maintenance

Follow these steps to safely and efficiently clean the                To clean the EnviroPod manually by hand, follow
EnviroPod using an inductor truck:                                    these steps:

 1   Open gully pit (See Section 3.2)                                  1   Open gully pit (See Section 1)

 2   Place the inductor hose over the material collected in the       2    Place the lifting hooks in the lifting loops of the filter bag
     filter bag and switch on the inductor                                 (See Photo 12)

 3   Using the inductor hose, suck out all of the sediment,           3    For extremely heavy and overfilled bags either use a
     organic leaf material, litter etc. collected in the filter bag        hydraulic lifting arm to lift the bag, or remove excess
                                                                           material using a shovel or similar piece of equipment.
 4   Allow the filter bag to be sucked up into the inductor
                                                                           IES prefers the use of a post hole shovel, due to the
     hose for a few seconds to allow for the filter mesh
                                                                           reduced strain on the back when digging and the ability
     pores to be cleaned. Care is to be taken that there are
                                                                           of the shovel to grab material vertically
     no sharp edges on the inductor hose that can damage
     the filter bag                                                   4    Lift the bag vertically off the supporting frame, ensuring
                                                                           that no undue pressure is placed on the filter bag.
 5   If material has built up around the overflows, use the
                                                                           (See Photo 13)
     inductor hose to clear the accumulated material
                                                                      5    Lift the bag clear of the stormwater pit (See Photo 14)
 6   Remove filter bag from the pit
                                                                      6    Position the bag over the truck or other collection
 7   Sediment retained in the gully pit grate is to be removed
                                                                           vehicle, taking hold of the loops at the base of the bag
 8   Back-opening channels are to be cleared of any debris                 (See Photo 15 and Photo 16)
     to ensure flow is not hindered. This debris can also be
                                                                       7   Lift and empty the filter bag by holding the bottom
     collected using the inductor truck
                                                                           lifting loops only (See Photo 17)
 9   All gully pit waste is to be removed from the pit
                                                                      8    Completely empty the filter bag (See Photo 18)
10   Check the EnviroPod unit (Section 3.4)
                                                                      9    Brush the filter bag with a stiff brush to remove bound
11   Check filter bag (Section 3.4)                                        sediment from the filter pores
12   Reinstate filter bag and gully pit lids                          10   Check the EnviroPod unit (Section 3.4)

                                                                      11   Check the filter bag (Section 3.5)

                                                                      12   Reinstate filter bag, ensuring bag is installed the correct
