While 70 percent of our planet is covered in water, only 2.5 percent of it is fresh water, and only 1 percent is surface water. This means that only 0.07 percent of the world's water supply is both fresh and accessible. Yet, this limited resource is needed in immense quantities for agriculture, industry, sanitation and health, and general human well-being. For most cities, water treatment is a burden as it is expensive, unattractive, and difficult to operate. Agua Inc. is changing the way the world uses and reuses water as an international leader in biological water treatment. They provide cities with sustainable and affordable treatment facilities, as well as a range of services to help cities with operations, such as management consulting, public-private partnerships, and concessionary programs, to help cities with operations. Whether in a bustling city in the Dominican Republic, the suburbs of Spain, or a desert community in Mali, Agua Inc. helps cities to achieve their regulatory requirements and infrastructure goals with clean, plant-based water technologies.
