Exploring Alternative Water Sources

11 mins 17 secs

Key learning objectives:

Outline the difference between potable and non-potable water
Understand the types of filtration
Identify alternative sources of water

Overview:

Potable water is water that is safe for human consumption. Non-potable water is water that isn’t safe to drink without further treatment. This treatment includes multiple filtration steps. With growing pressure on traditional water sources like surface water and groundwater, alternative water solutions are becoming more important. These technologies aim to create safe water where conventional sources are unreliable or insufficient.

Summary

What’s the difference between potable and non-potable water?

Potable water is water that is safe for human consumption - what we drink, cook with, and use for hygiene. Because it directly affects public health, it’s regulated by strict standards to ensure it’s free from contaminants. Non-potable water is water that isn’t safe to drink without further treatment. It comes from sources like industrial, domestic, and agricultural activities and includes wastewater.

What are the different types of water filtration?

Water filtration can be done in several ways. Some key filtration types include: gravel and sand filters, membrane technologies, chemical treatment processes, ion exchange, biological treatment, advanced oxidation, ph adjustment and fluoridation

What are the alternative sources of water?

With growing pressure on traditional water sources like surface water and groundwater, alternative water solutions are becoming more important. These technologies aim to create safe water where conventional sources are unreliable or insufficient. Key alternative sources include: desalination and air moisture capture.

How are new technologies helping create alternative water sources?

Emerging technologies are offering creative ways to produce water with reduced environmental impact and energy use. These are especially valuable in remote areas or places with limited infrastructure. Some examples include air moisture capture systems, off-grid purification systems, photovoltaic thermal systems and modular rainwater management systems.
