DID YOU KNOW?
Having access to safe and sufficient water and sanitation are now recognized as a basic human right.
Without food, human beings can live for 14 days or more
Human body can only survive a few days without
water
DID YOU KNOW?
One billion people worldwide live without clean, safe drinking waterTwo billion live without basic sanitation
So, how do you make sure they get pure drinking water that satisfies all their basic needs at low environmental impact?

THEN - FOG HARVESTING
However, it is not always suitable or practical, especially in dry and arid areas. This is where more modern techniques can be considered.
Fog fences are used to collect water from the humidity in the fog. It uses a mesh material strung tightly on poles, supported by gutter to collect droplets, fed into pipes, and then stored in tanks.
NOW - ATMOSPHERIC WATER GENERATOR
An atmospheric water harvester or atmospheric water generator (AWG) is a electricity-powered device that uses the dehumidification principle to make drinking water out of the moisture in the air.
ATMOSPHERIC WATER GENERATORS (AWG)
Produce more water in places with higher temperatures and humid climates
Need air with its trapped moisture to generate water
Need electricity (which can be obtained from the main power grid or solar panels, wind turbine)
Are sustainable, reliable, and produces potable water without complicated installation

ATMOSPHERIC WATER GENERATORS (AWG)
WORKING OF AWG
APPLICATIONS OF AWGRestaurants, bars, hotels, where copious amounts of clean water is required use AWG
Office environments that use bottled water units can do away with plastics when replaced with AWG
Remote locations, island resorts, mining sites, and instances where water scaling is an issue, use AWG
LIKELY SCENARIOS
• In such cases like, natural disasters and epidemics, the availability of AWGs can be timely in saving lives and improving sanitary conditions
• Disaster management organisations specify drinking water as a top priority to maintain good health
Portability, reliability of AWGs in generating pure drinking water will prove to be a vital technological intervention in sustaining lives and
health
BENEFITS OF AWG1 • Highly portable, economical and easy to maintain
2 • No expensive piping infrastructure investment is needed
3 • Easy installation
4 • No conventional water source required
5• Needs only to plug into electrical socket to generate fresh, pure
water
6 • Convenient, dependable, and safe
7 • Gives you total control over your water needs
STRENGTHS OF AWG
WEAKNESSES OF AWG
3 KEY TAKEAWAYSDespite widespread water pollution and shortages of drinking water, there is an
abundance of water around us
Water harvesting generators are the most environmentally
friendly way to extract pure quality water from the air at a
low cost
With emerging technologies, AWGs are now commercially available and mostly scalable
depending on need and location
