Attach G- Engineering Report

    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 recommended that
contractors develop their 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. 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.

This document consists primarily of the processes and tasks associated with the hand maintenance and
inductor maintenance procedures. It does not include detail of the traffic management requirements or
occupational health and safety requirements. Contractors or IES staff should utilise their own Employee
Health and Safety Manual, which details the policies and procedures for safe work.
