A shocking 2 million children die worldwide each year from waterborne diseases. Wastewater treatment does more than just clean water—it saves lives. The world faces an urgent water crisis, with only 3% of Earth’s water being safe to drink.
The numbers paint a grim picture. One liter of untreated wastewater can contaminate 8 liters of fresh water. Raw sewage releases harmful substances like PFAS, pharmaceuticals, and heavy metals that seep into surface water and soil. Proper treatment of wastewater creates reusable water and boosts the economy. Treated sewage water proves versatile—people can use it to flush toilets, wash cars, water plants and with the right technology, maybe even drink it.
This piece will get into the vital benefits of wastewater treatment plants and their positive environmental impact as we approach 2025. Modern treatment methods tackle public health issues while promoting environmentally responsible water management in our increasingly water-stressed world.
The Global Water Crisis and the Role of Wastewater Treatment
Water on our planet shows a big challenge. While water covers 70% of Earth’s surface, only 0.5% is fresh water we can use. This small amount must support almost 8 billion people. The task gets harder as populations grow and water patterns change.
Only 1% of Water is Readily Usable
Here’s a way to picture Earth’s water supply: if all water was 100 liters, we could use just half a teaspoon. The lack of water keeps getting worse. About 2-3 billion people face water shortages. One in four people can’t get safe drinking water. This makes water treatment crucial to save and use our limited resources well.
Untreated Wastewater as a Public Health Threat
About 80% of wastewater flows into water channels without treatment. This creates bad pollution and puts human health and sea life at risk. Raw wastewater often has dangerous pathogens, heavy metals, and toxic chemicals. Research shows that contact with wastewater leads to diarrheal diseases (odds ratio: 1.65) and helminth infections (odds ratio: 5.49) among farm workers and their families. Kids and people with weak immune systems face bigger risks.
Urbanization and Industrial Wastewater Growth
Cities keep growing and making more wastewater. China’s cities made 49.24 billion tons of household wastewater in 2017. This was 70.37% of all wastewater. Industries use 22% of the world’s water. Rich countries can clean 70% of their wastewater. Poor countries clean only 8%.
Clean wastewater helps both public health and business. The global industrial wastewater treatment market was worth USD 17.73 billion in 2023. It should reach USD 26.61 billion by 2030. SUSBIO and SUSBIO ECOTREAT are great options. They use natural treatment with few chemicals and help protect nature.
Key Public Health Benefits of Modern Wastewater Treatment
Modern wastewater treatment provides vital public health benefits way beyond the reach and influence of simple sanitation. These systems create safer water networks that protect communities from disease and support eco-friendly water practices.
Disease Prevention through Pathogen Removal
The elimination of pathogens stands as one of the most important benefits of wastewater treatment. Modern systems deliver impressive results – settling tanks remove 99.9% of helminth ova through sedimentation. Treatment plants show remarkable efficiency in eliminating dangerous bacteria, and some facilities achieve over 99% reduction of Escherichia, Campylobacter, Salmonella, and Shigella species. Advanced oxidation processes (AOPs) are a great way to get pathogen reduction capabilities, especially when you have other treatment methods. UV treatment (400 J/m²) combined with ozonation (1g ozone per g DOC) shows remarkable results by reducing E. coli by 99.0% and enterococci by 98.4%.
Reduction of Antibiotic-Resistant Bacteria in Effluents
Wastewater treatment plants act as vital barriers against antibiotic resistance genes (ARGs). Research shows that well-functioning facilities achieve ARG removal efficiencies ranging from 63.2% to 94.2%. This is a big deal as it means that antimicrobial resistance caused 4.71 million deaths globally in 2021. Advanced processes like UV radiation, ozonation, and membrane filtration systems boost ARB/ARG removal rates. UV treatment followed by chlorination works better than using either method alone.
Improved Sanitation in Urban and Rural Areas
Proper wastewater management transforms sanitation conditions in a variety of communities. Rural areas often discharge untreated wastewater directly into local surroundings and water bodies. Effective treatment prevents contamination of surface and sub-surface water. This protects the water table and ensures clean drinking water access. Nature-based solutions reshape the scene for urban informal settlements, where almost 25% of the global urban population lives. These systems improve living conditions for children and families who used to live in unhygienic conditions.
SUSBIO and SUSBIO ECOTREAT lead today’s most effective solutions with their biological treatment approach. They minimize chemical usage while handling high-strength industrial effluents effectively.
Environmental and Economic Advantages of Treatment Plants
Treatment plants provide significant environmental and economic benefits that go way beyond their role in protecting health. These facilities create powerful advantages when integrated into water management strategies.
Lower Freshwater Extraction via Reuse
Alternative water supply comes from treated effluent in regions facing water stress. This water serves non-potable uses like irrigation, industrial cooling, and groundwater recharge. The approach helps sustainable urban and agricultural development while reducing freshwater source pressure. To cite an instance, see how using treated wastewater just for irrigation could have reduced greenhouse gas emissions by 1.3 million tons in 2021.
Energy Generation from Sludge Methane
Raw wastewater holds hidden energy value. Anaerobic digesters stabilize sludge and capture methane-rich biogas that can be:
- Converted to electricity or heat
- Processed into renewable natural gas
- Used to fuel vehicle fleets
Globally generated sewage sludge has an impressive energy potential of 36.6 TWh per day. La Farfana treatment plant in Santiago, Chile modernized their facility with a USINR 227.83 million investment. This upgrade enabled biogas sales that generate USINR 84.38 million in annual profits.
