By reducing the level of surface water volume to sewers, you can extend the lifespan of network assets like pumping stations and treatment works.
Better wastewater management also improves water quality by lowering the frequency of spills to rivers from combined sewer overflows. Operationally it also reduces water treatment costs and carbon emissions.
Arup's expertise covers the design and implementation of wastewater networks, smart networks and predictive systems, pumping stations, treatment plants, natural treatment systems, sludge management and wastewater discharges and outfalls.
We are also experts in the field of wastewater-based epidemiology, providing wastewater monitoring solutions to monitor health trends, antimicrobial resistance and environmental pollution, regardless of the degree of sewerage infrastructure or resources available.
