Bowman & Associates will also undertake quality control responsibilities during the fabrication of the composite synthetic liner systems which will consist of Geosynthetic Clay Liner (GCL), a High Density Polyethylene (HDPE) Geomembrane and a leachate collection layer.
Fernview Landfill
Bowman & Associates has acted as Expert Environmental Consultants on behalf of Veolia Environmental Services during the permitting of the Fernview Landfill. Bowman & Associates has provided the services of site Due Diligence, Concept Design and preparation of Environmental Approval Documentation in accordance with Part V of the Environmental Protection Act.
North Bannister Waste Facility
Bowman & Associates acted as Environmental Engineering Consultants for Perthwaste during the development of a Class III landfill on a large rural site 100 kilometres south of Perth.The landfill will be capable of taking 200,000 tonnes per annum of waste from the Perth region. Bowman & Associates carried out the initial investigation, concept design and planning, environmental modelling and construction design facilitating approval for the facility.
LOCAL GOVERNMENT
Shire of Roebourne
Bowman & Associates was engaged by the Shire of Roebourne to assess the effects of the Cities of the North Plan on the Shire of Roebourne’s waste management services. The study was intended to provide information to assist the Shire to appropriately integrate waste management services into the Shire’s Master Plan.
Representatives from the Shire of Roebourne have visited landfills in Perth for a tour organised by Bowman & Associates to create awareness for the type of plant and equipment required to manage the increased waste volumes to be received at the 7 Mile Landfill.
Liquid Effluent Ponds for Shire of Roebourne
Shire of Roebourne has engaged Bowman & Associates to obtain Works Approval under Part V of the Environmental Protection Act for two new evaporation ponds to cater for projected growth in demand for liquid waste disposal.
City of Melville
Bowman and Associates were engaged to review waste management services for the City of Melville. The review included riding in trucks to learn firsthand of the issues that the City’s drivers have to face each day, analysing operating and productivity data and comparing the City’s in-house waste service to industry best standard.
Wagin Group of Councils
Bowman & Associates developed a Strategic Waste Management Plan on behalf of the Wagin Group of Councils and implemented the Regional Investment Plan funds for the Group on the back of the Strategic Waste Management Plan. Both of these projects involved liaison with stakeholders with varying interests, in most cases requiring Bowman & Associates to manage the consultation process. Working with multiple local governments required diligence in ensuring all viewpoints were considered and included in final reports. The project required an understanding of the overall waste management issues at a regional level, as well as those experienced locally within each constituent Shire.
City of Cockburn Henderson Waste Recovery Park
In 2008 Bowman & Associates was engaged to conduct a waste audit for the City of Cockburn to gain a better understanding of the composition of the Henderson Waste Recovery Park’s Commercial and Industrial (C&I) waste stream. The audit was based on the loads delivered to the site. Data collected explored the disposal habits of C&I waste generators based on truck collection routes. The findings of the review have led to the City of Cockburn introducing the retrieval of metals, timber and cardboard from the tipping face on a cost effective basis.
Strategic Waste Management Plans
Bowman & Associates developed Strategic Waste Management Plans on behalf of multiplelocal governments for the Southern Metropolitan Regional Council and the Western Metropolitan Regional Council. Each of these projects involved considerable liaison with stakeholders with varying interests and in most cases required the company to manage the consultation process for the preparation of the Strategic Waste Management Plans.
MINING AND RESOURCES
Birla Nifty Pty Ltd
Bowman & Associates undertook a comprehensive review of waste management procedures and technologies for Birla Nifty Pty Ltd, a subsidiary of Aditya Birla Minerals Ltd. The review covered all waste management operations at the Birla Nifty copper mine in Western Australia. Components of the report included life cycle carbon emissions assessment and assessment of waste products to identify recycling potential and logistical feasibility of various management strategies.
Crosslands Resources Ltd
Bowman & Associates was engaged by Crosslands Resources Ltd(CRL) to carry out a review of the existing waste management services at the Jack Hills Mine; a report including the future waste generation quantities was prepared for CRL.
Bowman & Associates thereafter was engaged to provide further waste management consultancy to develop the waste infrastructure plan for the proposed Jack Hills Expansion Project (JHEP).
FEASIBILITY STUDIES
Pilbara Regional Council
Bowman & Associates has been engaged by the Pilbara Regional Council to carry out a feasibility study on gasification technologies for the management of waste in the region. Carrying out this project involved a ‘tour’ of the region which included visits to landfills and waste transfer stations.
City of Fremantle
Bowman & Associates has previously been appointed to conduct an investigation into the feasibility of the City of Fremantle providing commercial recycling collection services. The project involved a considerable amount of background investigation, a triple bottom line assessment to identify the environmental, social and economic impacts of the project and consultation with businesses and the community to identify ‘drivers’ and barriers to commercial recycling collections.
Gascoyne Development Commission
The Gascoyne Development Commission (GDC) has previously engaged the services of Bowman & Associates to conduct a feasibility study into waste management at Gascoyne region landfills. This study involved a review of the current waste management operations at the four main landfills in the region and made recommendations for improving resource recovery and introducing greenwaste processing. The waste management plan covered all facets and was commended by the GDC Shire’s as a ‘hands on’ document which could easily be put into practice.
Town of Mosman Park
Bowman & Associates has previously conducted a study on behalf of the Town of Mosman Park to assess the feasibility of contracting out the Town’s waste collection service. The project required investigation, service evaluation, forecasting of costs and a triple bottom line assessment to identify the environmental, social and economic impacts of the project.
