ISLAMABAD, July 7 — The world faces a stark water reality as 2.2 billion people still lack access to safely managed drinking water, according to United Nations data from 2022. Agriculture remains the dominant consumer, accounting for 70 percent of global freshwater withdrawals, the Food and Agriculture Organization reports. The World Resources Institute’s Aqueduct Water Risk Atlas, updated in 2023, identifies 17 countries as extremely water-stressed.
Among them are Qatar, Israel, and Lebanon.
Technology offers new tools
The global desalination industry has expanded significantly, reaching a capacity of 107 million cubic meters per day in 2022, according to the International Desalination Association. This technology, which removes salt from seawater, has become increasingly affordable. The cost of desalinated water has dropped from $1.00 per cubic meter in 2000 to between $0.40 and $0.60 today.
Atmospheric water generators represent a smaller but growing segment of the market. Allied Market Research valued this sector at $2.8 billion in 2022, with projections reaching $13.5 billion by 2030.
The Orange County Groundwater Replenishment System in California demonstrates what large-scale water recycling can achieve. The facility produces 130 million gallons per day, enough to serve 850,000 people.
Market forces at work
The broader water and wastewater treatment technology market was valued at $78.5 billion in 2021, with Grand View Research projecting growth to $128.4 billion by 2028. For patients and families concerned about water quality — particularly those managing health conditions that require clean water — these technological advances offer reasons for cautious optimism. The encouraging part is that costs are coming down while capacity is going up.
But no single solution fits every situation. Patients should consider their local water quality reports and talk to their doctor if they have specific health concerns related to water consumption.
The choice of water treatment at home — whether filtration, boiling, or bottled water — depends on individual medical needs and local conditions.
Looking ahead
The coming years will test whether technological progress can keep pace with growing demand. Desalination costs may fall further as membrane technology improves. Atmospheric water generators could become more efficient.
And recycling systems like Orange County’s may see wider adoption. What remains clear is that the gap between water supply and demand is not closing on its own.
The 2.2 billion people without safe drinking water need solutions that are both effective and affordable. The market data suggests investment is flowing into this space, but translating investment into access for the most vulnerable communities remains the central challenge. As always, patients and families facing water quality concerns should consult their doctor for guidance specific to their health situation.
Clean water is essential for treatment outcomes and daily wellbeing alike.
