The cost of water treatment and access
Water pollution is a global issue that poses a serious threat to human health and the environment. The cost of water treatment and access is a significant aspect of the financial impact of water pollution. The lack of access to safe water and sanitation has far-reaching economic consequences. According to the World Health Organization and UNICEF, the lack of basic water and sanitation results in a global loss of $260 billion each year. This loss is attributed to the time spent collecting water, reduced economic productivity, and the burden of healthcare expenses.
Unsafe water and inadequate sanitation disproportionately affect women and girls, who are often responsible for water collection, spending hours each day waiting in lines or walking to distant sources. This time spent on water collection could be utilized for income-generating activities, education, or other opportunities.
Household finances are significantly impacted by water and sanitation access. For instance, Leneriza from the Philippines previously spent more than 20% of her monthly income on purchasing water from a vendor. By obtaining a small, affordable loan, she was able to connect her home to the local water utility, reducing her monthly water expenses to just $4.50.
Universal access to basic water and sanitation would bring about significant economic benefits. It is estimated that every $1 invested in water and sanitation yields a $4 economic return. This includes reduced health costs, increased productivity, and fewer premature deaths.
Water pollution also affects economic growth, particularly in middle-income countries. When rivers become heavily polluted, downstream regions experience a reduction in economic growth of up to 2.5%. This impact is attributed to the negative consequences on sectors such as health, agriculture, tourism, real estate, and aquaculture/fisheries, which rely on a clean and healthy water supply.
The cost of water treatment is a significant expense, especially for wastewater treatment facilities. These facilities are essential for reducing pollutants and ensuring that treated water can be safely discharged back into waterways. However, aging and overwhelmed sewage treatment systems can release billions of gallons of untreated wastewater each year, leading to environmental and health issues.
