Performance
Typically, laboratory testing provides a means to generate hydraulic and basic performance data, but it
should also be complemented with long-term field data. Gully pit baskets that operate under unrestricted
flows require both a combination lab and field studies to accurately understand performance.

Ocean Protect has and is undertaking field testing locally in Australia and copies of the supporting articles are
available upon request from Ocean Protect.

Gully pit baskets and associated technology have been available in Australia and overseas for more than 20
years. The OceanGuard technology has design elements and removal performance that are the same as some
off-patent technologies, such as the previous generation EnviroPod previously sold by Stormwater360
Australia (Now Ocean Protect) under licence.

The OceanGuard meets all previous performance data and current approvals across Australia in terms of
pollutant removal, flow rate and head loss. Please contact your Ocean Protect representative for more
information.

Please contact your Ocean Protect representative to obtain the StormFilter approval status in your area.

Maintenance
Maintenance of the OceanGuard is simple effective and seldom requires confined space entry or specialised
equipment, often being completed by hand without the need of vacuum equipment. Simply remove the
OceanGuard from the pit with the tags provided and invert the bag into a waste bin. Inspect the liner and
brush by hand or spray with a pressure washer if required to rejuvenate the filtration bag. Record the
information and replace the filtration bag.

Inspection & Cleaning
The Ocean Guard® system should be inspected at regular intervals from 1-2 months during the first year of
installation to ensure optimum performance. The frequency at which the OceanGuard will need to be
maintained will depend on site activities, land uses, catchment area and this size of OceanGuard installed, 1-
6 times annually (3-4 typ.).

For further information please refer to the OceanGuard Operations and Maintenance Manual.
