Projects by Service – Water
Sydney Olympic Park – Leachate Treatment Wetland and Irrigation Liasion with NSW EPA | Treatment wetland design | Effluent irrigation modelling and design
AWC, in partnership with EnviroPacific and Henry and Hymas Consulting Engineers, completed the detailed design and construction of a leachate treatment and disposal system at Sydney Olympic Park.
Wetland modelling and design, construction supervision
The Coolum STP wetland trial is the most comprehensive investigation into the performance of constructed wetlands for pollution control in recent years.
Pollutant reduction modelling | Detailed design of treatment systems | Construction supervision
AWC have been working with the Burnett Mary Regional Group since 2010 to provide remediation measures that combat diffuse pollution wtihin the Great Barrier Reef catchment.
Geomorphic assessment of erosion | Hydrologic/hydraulic modelling | Ecology | Detailed designs
Iron Pot Creek and associated tributaries have areas of extensive erosion, caused by a combination of historical land clearing, urban development and construction of infrastructure.
AWC and Bligh Tanner Consulting Engineers collaborated in providing a holistic erosion and bank stability strategy.
Water sampling | Data analysis
Gold Coast City Council are installing Floating Reed Beds (FRBs) within three urban lakes on the Gold Coast. To determine if the installation of FRBs within the three lakes changes the level of pollutants and water quality within each lake system, regular water quality monitoring was completed to establish baseline datasets to provide for future data comparison.
Groundwater assessment | Ecological review | Modelling
The Cumbalum Urban Release Area (CURA) is a strategic rezoning to help provide for future housing needs within the Ballina Shire. Following preliminary site investigations by a number of consultants, AWC were commissioned to investigate post-development groundwater scenarios with regard to potential impacts on endangered ecological communities, threatened fauna habitat and the adjacent Ballina Nature Reserve in order to determine the efficiency of stormwater and WSUD proposals and review proposed mitgation measures.
Onsite wastewater management at several country public schools and Reviews of Environmental Factors (REFs)
Soil testing | Review of Environmental Factors | Effluent modelling
The NSW Department of Public Works engaged AWC to conduct soil and site assessments for the upgrade of onsite wastewater treatment and disposal systems at several Northern NSW public primary schools/education facilities at The Channon, Dorroughby, Upper Bonalbo, Modanville and Wilsons Creek.
Riparian restoration | Shoreline stablisation | Landscape design
AWC was engaged by Spotless Services Australia Limited to undertake a review of options for shoreline rehabilitation within the Australian Navy Cadets lease area at Golden Beach.
Stormwater quality modelling (MUSIC) | Strategic planning | Tasmanian state legislation
Simplot (a vegetable processing factory) engaged AWC to prepare a Stormwater Managment Plan (SWMP) for their Devonport Vegetable Processing Facility, incorporating a concept design of a stormwater treatment and reuse system and risk managment plan.
AWC have been awarded the Nerang River Estuary Ecosystem Health Study. The purpose of the Nerang Estuary Ecosystem Health Study is to accurately assess the health of the estuary and provide Gold Coast City Council with a strategy for managing the Nerang River Estuary.
Landscape design | Erosion control | Estuary Management | Review of Environmental Factors
To remediate problems with the Iluka Bay foreshore area, AWC completed detailed site assessments, design drawings to rectify erosion and a Review of Environmental Factors to implement the works.
Catchment pollutant modelling | Riparian assessment | Aquatic fauna surveys | Community consultation
AWC were engaged by Gold Coast City Council to complete the Coolangatta Creek Catchment Management Plan. The Plan will provide an updated management tool that will enable GCCC, government agencies and stakeholders to take a co-ordinated approach to the protection and management of Coolangatta Creek.
Knowledge of major road infrastructure projects | Understanding of potential environmental impacts
An Environmental Management Plan (EMP) was prepared by AWC (on behalf of Australian Wetlands Pty Ltd) for the Department of Transport and Main Roads (TMR) specific to the upgrade of the Bruce Highway between Cooroy and Curra.
Soil testing | Aquatic weed management | Contaminated soil
Waterbird Park is an urban parkland located at Explorers Way, Carrara. The park has a constructed wetland comprised of two sections, with dense infestations of Mexican waterlily. Due to the poor performance of the wetland and the difficulty in eradicating Mexican waterlily, Gold Coast City Council proposed the re-design of the system to increase performance and aesthetics of the watercourse.
Soil testing | Biosolids application modelling | NSW legislation
Byron Shire Council propose to provide biosolids from sewage treatment plants under their management for beneficial use on agricultural land, namely two sites under management as working dairy farms. The sites of the proposed biosolids application are in areas currently cultivated for cropping.
Seagrass and Mangrove Transplanting
As specialists in the creation and management of aquatic ecosystem, Australian Wetlands were engaged to construct, establish and maintain a mangrove wetland system in the large-scale redevelopment of the Southport Broadwater parklands on the Gold Coast.
AWC have been monitoring the effect of artificial opening events on estuary and drain water quality and nearby wetland vegetation since 2008. Since 2008 AWC have increased the scale of environmental monitoring of the opening events to include 5 monitoring sites over 7 days post opening and installed conductivity and water level loggers throughout the catchment to better understand the mechanisms behind the ‘need’ to artificially open the sand barrier between the Belongil Estuary and the ocean.
Recent floods across the Burnett-Mary region have resulted in wide-spread riparian erosion and stream bank degradation. The Burnett Mary Region Group (BMRG) acquired funds from the federal government to rectify a number of sites across the region. AWC undertook a rapid riparian restoration assessment, concept retification designs and costings for all 13 sites.
Site Investigations | Community Consultation | Water Quality & Wetland Rehabilitation Strategies
AWC produced a Wetland Restoration Strategy developed in accordance with the Northern Rivers Catchment Blueprint, setting the framework for integrated and holistic management into the future.
Treatment Wetlands Feasibility and Pilot Study | Concept Design
As part of the Western Corridor Recycled Water Project, an Advanced Water Treatment Plant is being constructed at Luggage Point which will discharge a brackish waste stream of reverse osmosis concentrate . AWC undertook a Feasibility Study on the suitability of available land for constructed wetlands to treat this waste stream, a concept design and pilot study of the effectiveness of several constructed wetland designs to treat this effluent type.
Riparian restoration | Construction supervision | Ecological design
Purpose: To utilise joint funding from Byron Shire Council and NSW Fisheries for improvement works within the Brunswick Estuary.
Wetland Design and Relocation | Construction Methodology
AWC worked within developmental parameters to provide a method and detailed woks for the translocation and careful re-creation of the existing wetland to a new site. This was done by considering soil characteristics, hydrology and physical topography of the wetland.
Soil testing | Biosolids application and effluent irrigation modelling
The purpose of this project was to determine the soil characteristics of the Bangalow STP Property, classify the effluent of the STP and the biosolids produced at Bangalow, Byron Bay and Ocean Shores STPs.
