Stormwater Management Plan - Rev 1

     6. SPEL StormSack Repairs
     Depending on the extent of the damage to the SPEL StormSack unit, it can
                                                                                                               CHAPTER          4
     usually be repaired.
     Small tears to the filter bag can be repaired by either sewing the tear back
     together with additional fabric to increase the strength of the stitching, or by
     sewing a patch of filter material onto the filter bag.
     If large tears or irreparable damage to the frame and structure are present, it is
     advisable to replace the components.
     All required spare parts can be sourced from SPEL Environmental at a cost to
     the owner of the SPEL Stormsack.




     7. Emergency Procedures
     Spills and blockages can be detrimental to the performance of a stormwater management system, potentially damaging
     the surrounding built infrastructure, waterways and environment.

     Spill Procedures
     In the event of a spill discharging into a gully pit, all effected sediment must be removed from the filter bags and the filter
     bags are to be removed and replaced with new filter bags. All additional cleaning as a result of the spill should also be
     carried out in accordance with the normal operation procedures.

     Blockages
     In the unlikely event of surface flooding around a gully pit which has a SPEL StormSack fitted, the following steps should
     be carried out:
     A.	Check the overflow bypass.
     B.	If overflow is clear and surface flooding still exists remove the SPEL StormSack and check the outlet pipe for
             blockages. Removal of the SPEL StormSack can be difficult if clogged with sediment and holding water.
     C.	If the filter is clogged brush the side walls to dislodge particles trapped at the interface allowing water to flow
             through the filter.
     D.	If the outlet pipe is blocked, it is likely that a gully sucker truck will be required to unblock it. Litter can be removed
             from the SPEL StormSack using the gully sucker truck before the SPEL StormSack is removed. If a gully sucker
             truck is not available and the SPEL StormSacks need to be removed by hand follow the below steps.
            i. Remove excess debris by hand or brush the side of the filter bag
            ii. Remove entire SPEL Stormsack by taking hold of the inside of the frame.
            iii. Unblock the outlet pipe
