Water contracts for Brazil, Panama and Chile

Santiago Region restores water quality in the natural environment and anticipates an increase in the population A consortium composed of AGBAR (51%) and Degrémont (49%) has signed a EUR260 million contract with Aquas Andinas to extend and then operate for five years the wastewater treatment plant at Mapocho in Santiago Valley, and modernise the facility to ensure energy recovery from sludge. This new contract is in line with the sustainable development policy of the Region of Santiago, aimed at restoring the water quality of natural environments and preparing for a population increase. The project's objective is to rehabilitate and optimise existing processes, while doubling the capacity to treat urban effluent in the region from 380,000m3/day (2 million equivalent inhabitants) to a maximum future capacity of 760,000m3/day (4 million equivalent inhabitants). Modernising the equipment will allow optimum exploitation of the energy potential of the facility , which is based on the digestion of sludge to capture bacterial heat and produce electricity. The biogas will thereby produce more than 60% of the electricity needed for the plant. In addition, right from the point of designing the plant, process optimisation has been put in place to curb environmental impact and greenhouse gas emissions during construction and operation.

Construction of a wastewater treatment plant to clean up the Bay of Panama In a consortium with Odebrecht, one of Brazil's largest builders, Degrémont has signed a contract with the Panama Ministry of Health to design, build and operate for four years an urban wastewater treatment plant for the capital, worth a total EUR170 million, including EUR80 million in sales for Degrémont. The plant's construction is financed by the Inter-American Development Bank (IADB), the Japan International Cooperation Agency (JICA) and the Panamanian government. The project is part of an ambitious environmental protection and wastewater treatment programme launched in Panama at the turn of the millennium which also includes plans for, among others, renewing and extending the wastewater treatment infrastructure. The new plant is aimed at cleaning up the Bay of Panama by treating effluent before it is released into the environment. With a capacity of 238,000 m3/day, the plant will treat effluent from one million of the city's inhabitants. The plant will provide facilities for biological treatment and sludge digestion, while streamlining energy costs by implementing cogeneration and heat recovery systems. Biogas from the sludge will produce 100% of the electricity needed to heat the buildings and digestors, or 20% of the plant's total energy needs. Located in a seaside mangrove swamp and soon to be surrounded by the city, the plant has been designed to blend seamlessly into the environment. A biological odour control system is also in the pipeline to reduce the risk of odour nuisance for people nearby.

New wastewater treatment and process water recovery plant in Brazil Degrémont and Ondeo Industrial Systems have signed, with the EGESA-TKK consortium, which is in charge of constructing the twelfth Petrobras refinery in Northwest Brazil, a contract to design and build a treatment and recycling plant for residual process water from the new installation. The total turnover of this contract will be EUR97 million, including EUR49 million for Degrémont and Ondeo Industrial Solutions. The facility will use a pretreatment unit and a membrane bioreactor treatment unit to reuse the water to produce demineralised water for the site. This advanced technology, used successfully in many other applications, has been developed for water recycling, and will provide Petrobras with a low-cost resource while limiting the quantity of water taken from the natural environment.
