RFI - Attachment H - Stormwater Management Plan_Issue C_

15 May 2019


The Stormwater 360 stormfilters operate by filtering stormwater through media-filled filter cartridges.
As the stormwater percolates through the cartridges, pollutants, particulates, surface scums and
floating oil and greases are captured within the filter media. Once filtered through the media, the
treated stormwater is directed to a collection pipe.
The collection pipe discharges the treated water from site once the state planning policy requirements
are met.

Enviropods will be fitted to each field inlet.

The Enviropods consist of a screening bag supported by a filter box and structural cage. Modular plastic
deflector panels attach to the filter box and guide the flow of water to the screening bag. The screening
bag captures pollutants and allows water to pass through to the outlet pipe. Absorbent material inside
the screening bag captures oil and grease. Openings in the filter box allow water to bypass the screening
bag during high flow conditions.


5.4.4 Maintenance

For the Stormwater 360 Enviropods and Stormfilters, maintenance can be performed with a vacuum
truck to remove captured soil, sediment and floatables. Detailed maintenance techniques can be found
in the Stormwater 360 Operations and Maintenance Manual attached in Appendix 4.

Maintenance will be completed regularly to ensure that the devices are performing as designed to
ensure that the stormwater discharged from site is meeting the requirements of the State Planning
Policy and Noosa Council. This will be monitored as part of the development requirements.


5.5       Construction Phase (Sediment and Erosion Control)

5.5.1 Intent of Erosion and Sediment Control Management Plan

To prevent stormwater contamination (of watercourses) and the release of contaminated stormwater
and wastewater by ensuring compliance with the Environmental Protection Act 1994 and
Environmental Protection (Water) Policy 2009.

5.5.2 Implementation Strategy

Establish control measures and best practice approaches to prevent stormwater contamination and
minimise the risk and adverse effects of erosion and sedimentation. All Erosion and Sediment Control
measures must be designed, constructed and maintained in a manner that is commensurate with the
site’s erosion risk.

5.5.3 Erosion and Sediment Control Measures

          Obtain a licence or approval to operate activities that are classed as environmental relevant
           activities (i.e. they have the potential to cause environmental harm).
          Implement and maintain appropriate control measures to prevent sediment leaden wastewater
           and other potential pollutants such as oil, paint and wet concrete from entering the stormwater
           system via stormwater drains and gullies. The control measures which must be considered to be
           adopted are:
                Limit site access during construction to minimise disruption to traffic
