Rio Tinto Coal Mozambique (RTCM) has substantial coal resources in the Tete region in Mozambique. First production from these assets is now underway and to meet future forecast mine demand and export to a Southern African utility, a dedicated coal fired power plant has been proposed by RTCM. Aurecon was previously engaged as owner's engineer to assist RTCM in the preparation of a business case study and the Order of Magnitude (OoM) study. Aurecon is currently providing engineering services for the power station and associated infrastructure, including updates of the existing Environmental Impact Statement. The project includes demolition of existing, and construction of new, FIFO accommodation and the central facilities buildings, electrical infrastructure, road works, landscaping, residential lot subdivision and construction of residential dwellings. Other works being undertaken include a town administration and training centre, waste water pumping stations, and replacement of the waste water treatment plant, a telecommunications infrastructure upgrade, and community parks. Aurecon is managing procurement and onsite construction of the project packages, including monitoring the sites, works supervision, Health & Safety, environmental, contract administrator and superintendent services on behalf of the client. Client Rio Tinto Coal Mozambique Sewage Treatment Works at Orapa Mine Botswana Client Debswana Aurecon provided design and construction monitoring services for new wastewater treatment works with a capacity of 3.5 ML/day at Debswana's open-cast mine in Orapa. The works replaced the existing facility that was made redundant by expansion of open-cast operations at the mine. Aurecon's role included the design of the inlet works (screening and degritting), biological reactor, clarifiers, disinfection, and sludge lagoons. In addition, Aurecon undertook the process and hydraulic design, topographical and geotechnical investigations, structural and civil design, mechanical and electrical services design, compilation of tender documentation, construction supervision, and the eventual commissioning of the works. The design included two sludge lagoons where waste sludge is discharged for stabilisation and settling, with the supernatant water then being used for irrigation of parks. Another design element was an emergency storage dam where excessive flow can be diverted for gradual inclusion into the influent for treatment. Aurecon Mine support facilities 7
