1   INTRODUCTION

The following report details the recommended methods for cleaning and maintaining the
Enviropod Stormwater Gully Pit Insert. The aspects associated with cleaning included in
this manual are methods for grate removal, filter bag cleaning, unit inspection, filter bag
rejuvenation and the re-installation of the filter bags. This plan should be used in
conjunction with the appropriate traffic management plans and site safety plans produced
for each project. Other Stormwater360 (IES) documents which IES staff should use in
conjunction with this report include the IES Employee Health and Safety Manual. It is
recommend that contractors develop there own health and safety plans for activities to
ensure that the workers are placed in a safe work environment.

Each stormwater treatment device must be inspected and maintained regularly to ensure it
is working properly throughout the estimated design life. The Enviropod filters require
servicing every 1 - 6 months depending on site characteristics, however the maintenance
requirements are less labour intensive than alternate traditional treatments. During each
inspection and clean, details of the mass, volume and type of material observed should be
record to provide ongoing data for future management plan revisions and the optimisation
of the maintenance frequency. It is essential that maintenance (including inspections,
recording and reporting) be carried out in a systematic manner and is carried out by
qualified and experienced personnel. It is also advisable that the treatment device owner
has a nominated person responsible for overseeing the management process.

Maintenance is an essential component of stormwater management enabling ongoing at
source control of stormwater pollution. Maintenance will also prevent failures such as
structural failure (e.g. prevents blocked outlets) or aesthetic failure (e.g. debris
accumulation). All stormwater treatment devices require maintenance to ensure the
ongoing performance of the system.

Stormwater360 (IES) is a specialised stormwater consultancy with trained and
experienced staff. The company has a comprehensive database with detailed information
on every Enviropod filter sold and serviced by IES (formerly Enviropod), collecting site-
specific data that can be easily accessed and analysed as required.
