Comprehensive management of resources
The development of sewerage services, in the broadest sense, is one of the challenges being faced by Agbar.
The company takes care of the planning, design and operation of wastewater treatment plants, the treatment of difficult waters, the measurement and control of environmental odours using olfactometry, the analysis of the environmental impact and the thermal drying of wastewater treatment plant sludge.
The total sewerage networks managed amount to 41,586 kilometres.
