4     Emergency Procedures

4.1    Spill Procedures

In the event of a spill discharging into any gully pit all sediment is to be extracted and the
filter bags are to be removed and replaced with rejuvenated filter bags. Normal operation
procedures apply to additional cleaning as a result of spills.


4.2   Blockages
In the unlikely event of surface flooding around a gully pit fitted with an Enviropod the
following steps should be carried out:

Check Enviropod over flow bypass. The Enviropod filter has been designed with an
overflow mechanism built into the filter box. If surface flooding still exists check the
overflow slots underneath the rubber seal. If debris is lodged in the overflow slots these
can be easily cleared by hand or steel rod.

If overflow is clear and surface flooding still exists remove Enviropod and check outlet pipe
for blockages.

Removal of the Enviropod may be difficult if the filter is clogged and the Enviropod is
holding water. If the filter is clogged, brush the side walls of the filter with a yard broom or
similar. This will dislodge particles trapped at the interface allowing contained water to
flow through the filter.

If the outlet pipe is blocked, it is likely that a gully sucker truck will be required to unblock it.
Debris should be removed from the Enviropod with the gully sucker truck before removal
of the Enviropod filter.

If a gully sucker truck is not available and the Enviropod needs to be removed by hand,
follow the steps below:
 Remove excess debris by hand or brush the side of the filter.
 Lift and place filter ring through the filter box and into cage.
 Remove Filter box.
 Lift cage containing filter bag and ring out of the pit.
 Unblock outlet pipe.
