Why Wastewater Treatment Crucial for Development

Clean water is an essential element for human health, wellbeing and prosperity. Whether used for drinking, cleaning, food production or industrial output, access to sufficient water resources is a basic human need. Access to sufficient and safe sanitation facilities is also vital for hygiene, disease prevention, and human health.

As global population grows (increasing agricultural, industrial and domestic demands for water), and water demand increases, water stress and the risk of water scarcity is now a common concern. This is even more applicable for particular regions with lower water resources and/or larger population pressures.

Water Crisis: The Problem and Our Solution

Despite limited availability of freshwater for human use (availability estimated at a worldwide total of 4,200 cubic kilometres), withdrawals continue to increase globally. By 2030, without a substantial improvement in water management, this figure could be close to 7,000 cubic kilometres.

Global Fresh Water Pollution

Global Fresh Water Pollution

Most fresh water pollution is caused by the addition of organic material which is mainly sewage, but can also be be food waste or farm effluent. Other forms of fresh water pollution include micro-plastics, chemicals, and nasty toxins from household cleaning products. 

Water Scarcity and Wastewater Problem

Water Scarcity and Wastewater Problem

As populations increase, competition between uses of water and regulation of wastewater will develop into significant policy concerns. Already, India and China have been faced on numerous occasions with the decisions between providing for water-heavy crops or population settlements.

Global Water Withdrawals

Global Water Withdrawals

Ten countries withdraw more than 100 percent of renewable freshwater resources, of which 7 in the Arabian Peninsula, 1 in Northern Africa and 2 in Central Asia.
