Why is Water Treatment Important? 6 Main Reasons

Why is water treatment important? Clean water is essential for life, health, and sustainable development. As populations grow and face increasing pollution threats, effectively treating water has perhaps never been more crucial. In this comprehensive guide, as a professional water treatment supplier, we’ll take a deep dive into all facets of water treatment to illustrate exactly why it’s so vital in the modern world.

The Basics of Water Treatment

Before exploring why water treatment is important, let’s quickly go over what it involves.

Water treatment refers to any process that improves water quality to make it suitable for human use and consumption. It aims to remove contaminants, impurities, chemicals, and particulate matter from water to deem it potable (safe for drinking).

Common water treatment processes include:

• Coagulation and flocculation – Chemicals with a positive charge are added to attract the negative charge of dirt and other dissolved particles. This causes them to clump together and form larger particles called floc.
• Sedimentation – Floc particles become heavy enough to slowly sink to the bottom. This separates solids from water.
• Filtration – The clear water then goes through filters of sand, gravel, and charcoal to remove smaller dissolved particles.
• Disinfection – Chemicals like chlorine kill remaining viruses, bacteria, and parasites.

After treatment, the cleaned water is ready for human use and consumption.

Why Effective Water Treatment is Crucial

Now let’s examine why sufficient water treatment is so important:

Removing Hazardous Contaminants

Water naturally collects impurities and pollutants from the atmosphere, soil, human activity, agriculture, and industry. These include:

• Microplastics
• Toxic chemicals like lead, mercury, pesticides.
• Sewage and fecal contaminants carrying bacteria, viruses, protozoa, and parasites.

Consuming such untreated, tainted water leads to waterborne illnesses like cholera, dysentery, typhoid, legionellosis, and polio.

The WHO estimates waterborne contaminants cause over 500,000 diarrhea deaths every year. Effective water treatment is crucial to remove these hazardous substances and protect human health.

Making Water Safe To Drink

Treating water doesn’t just remove risks, it also makes water potable for drinking and cooking. Disinfecting water kills pathogens that cause typhoid, dysentery, polio, and cholera, for example. Removing particulates, chemicals, heavy metals also renders water safe.

Globally, at least 2 billion people use contaminated drinking water sources, risking contracting diseases, infections, and poisoning.

Sufficient treatment transforms even filthy sewage water into sparkling clean, contaminant-free drinking water that sustains health rather than destroys it.

Supporting Population And Development

Over 70% of Earth is covered in water, but remarkably only 1% of freshwater is easily accessible for human use.

With global populations projected to grow to 8.5 billion by 2025, water demand for drinking, domestic use, manufacturing industries, food production will intensify exponentially.

Water treatment supports growing development by recycling used untreated dirty water and rendering it reusable. This protects finite groundwater and ecosystems while satiating rising demand.

Even as populations swell, effective treatment means there is enough life-sustaining water for all human needs.

Why Water Treatment is Important

There are compelling ethical, environmental, social and economic reasons why water treatment is an essential cog to global progress, sustainability and human development.

1. Prevents Water-Borne Illnesses

Removing pathogens, chemicals, heavy metals, and fecal contaminants enables water to sustain health instead of transmit diseases when consumed. Clean water is quite literally the difference between life and death.

The WHO estimates over 485,000 people die annually from water-borne illnesses like cholera, typhoid, diarrhea. Tennant estimates that investment into treatment prevents 241 million diarrhea cases yearly.

2. Removes Toxic Substances

From heavy metals like lead, copper, mercury to pesticides, pharmaceutical residues, industrial effluents – there’s no limit to hazardous pollutants in our water today.

Adequate treatment tracks an expansive spectrum of emerging and well-established toxins to remove them before they enter veins. Governments keep updating substance guidelines and protocols.

3. Universal Human Right

The UN recognizes clean water access as a fundamental human right since 2010. Water treatment fulfills this right by tackling scarcity and equitably redistributing this precious, life-sustaining resource. It liberates the disadvantaged from the burdens of thirst, disease, and indignity.

Investment into water treatment recognizes that social, racial, economic status should not determine one’s entitlement to clean water.

4. Supports Food Security

70% of global water use fuels agriculture for crops, livestock, produce, dairy and meat across the world. Water treatment enables the dependable reuse of wastewater from sewage plants and industry for irrigation and farming. Enough water means reliable food security.

UN Water reports that we’ll require 55% more water for agriculture by 2025 to combat hunger. Water treatment is crucial for realizing universal food security.

5. Saves Aquatic Ecosystems

Releasing untreated wastewater crammed with waste, chemicals, litter into environments destroys entire ecosystems reliant on clean water. It critically endangers aquatic life like fish, plant life, mammals while degrading water sources.

Responsible water treatment contains environmental damage by intercepting billions of tonnes of pollution yearly and preventing it from entering natural habitats.

6. Economic Sense

Comprehensive water treatment infrastructure requires intensive capital investment but offers attractive medium-long term ROIs from social, environmental, healthcare and economic returns.

The CDC estimates that for every $1 invested into water treatment infrastructure generates $21 in costs saved and productivity gained. It’s why development banks and organizations continue investing billion into this space.

On an individual level, home treatment solutions save thousands in buying bottled water or paying healthcare costs due to water-borne diseases.

Conclusion

Treating water is a complex, continuous and evolving science that requires sizeable expertise, investment, rigor, patience and perspective. But the fruits of these labours are indisputably amongst humanity’s most rewarding – saving lives, furthering progress.

There remain too many without access but solid inroads allow hope for a future where no one is denied this basic necessity – clean water.

Why is water treatment important? It lays the foundation for life itself to flourish uninterrupted and undiminished – towards greater equity, hope and human potential fully realized. Our imperative is to honor this truth through will and toil.
