Unleashing the Wonders of the Hydrological Cycle
Water's journey from Earth to Sky back again from Sky to Earth. The continuous process by using solar Energy.
The Hydrological Cycle is a continuous process of water exchange between the Earth’s surface and the atmosphere. It is also known as the Water Cycle. The cycle consists of three main processes: evaporation, condensation, and precipitation.
During evaporation, water from oceans, lakes, and rivers is converted into water vapor by the sun’s heat. This water vapor rises into the atmosphere and forms clouds through condensation. When the clouds become heavy, they release water droplets in the form of precipitation. Precipitation can take many forms, including rain, snow, sleet, and hail.
The Hydrological Cycle is a vital process that helps maintain the balance of water on Earth. It is responsible for replenishing freshwater sources, such as rivers, lakes, and aquifers, and for regulating the Earth’s climate. The cycle also plays a crucial role in the distribution of nutrients and minerals throughout the planet.

See the World's Water through a New Lens
Water stress refers to the condition where the water demand exceeds the available supply. It is a global problem that affects billions of people around the world. Water scarcity can occur due to various reasons, including climate change, population growth, and inadequate infrastructure.
Water scarcity is a relative concept. The amount of water that can be physically accessed varies as supply and demand change. Water scarcity intensifies as demand increases and/or as water supply is affected by decreasing quantity or quality.
The situation is expected to worsen in the coming years due to global warming and population growth. As the global population increases and resource-intensive economic development continues, many countries’ water resources and infrastructure are failing to meet
Water stress can have severe consequences on public health, economic development, and global trade.
2.3 billion people live in water-stressed countries, of which 733 million live in high and critically water-stressed countries. (UN-Water, 2021)
Working Towards a Secure Water Future
Water security refers to the reliable availability of an acceptable quantity and quality of water for health, livelihoods, and production, coupled with an acceptable level of water-related risks. It is a complex concept that encompasses not only the absence of water scarcity but also its presence when there is too much of it. UN-Water proposes a definition of water security as the capacity of a population to safeguard sustainable access to water for various purposes Water security also includes the capacity of a population to safeguard sustainable access to water in a climate of peace and political stability.
Clean Water for a Better World
Water contamination refers to the presence of harmful substances in water bodies that make it unsuitable for human consumption or other uses. These substances can include chemicals, microorganisms, and other pollutants that can cause serious health problems. Water pollution can occur due to various reasons such as agricultural runoff, industrial waste, and sewage leaks. It is important to take measures to prevent water pollution and protect our water resources.
Water pollution, is the release of substances into subsurface groundwater or lakes, streams, rivers, estuaries, and oceans to the point where the substances interfere with the beneficial use of the water or with the natural functioning of ecosystems. In addition to the release of substances, such as chemicals, trash, or microorganisms, water pollution may also include the release of energy, in the form of radioactivity or heat, into bodies of water.
It is important to take measures to prevent water pollution and protect our water resources.
Working Towards a Cleaner, Greener Future
Water pollution is the contamination of water bodies by human activities or natural processes that negatively affect their uses. It can be caused by sewage, industrial, agricultural, or urban runoff. The effects of water pollution include aesthetic, biological, chemical, and physical problems. Some of the common pollutants include pathogens, organic matter, nutrients, heavy metals, and chemicals. Water pollution can have serious consequences on human health, aquatic life, and the environment.
There are several ways to prevent water pollution. Some of the common methods include reducing the use of pesticides and fertilizers, properly disposing of hazardous waste, and conserving water. Additionally, it is important to raise awareness about the importance of clean water and the impact of water pollution on the environment.

Clean Water for Life: Our Vision
Water treatment is the process of removing contaminants and undesirable components from raw water to make it safe for specific end-uses such as drinking, industrial, irrigation, or recreation. Public drinking water systems use different water treatment methods to provide safe drinking water for their communities. Public water systems often use a series of water treatment steps that include coagulation, flocculation, sedimentation, filtration, and disinfection1. The five steps involved in water treatment
Coagulation is when chemicals with a positive charge are added to the water to neutralize the negative charge of dirt and other dissolved particles in the water. The particles bind with the chemicals to form slightly larger particles. Flocculation is the gentle mixing of the water to form larger, heavier particles called flocs. Sedimentation is when flocs settle to the bottom of the water because they are heavier than water. Filtration is when the clear water on top is filtered to separate additional solids from the water. Finally, Disinfection is when one or more chemical disinfectants are added to kill any remaining parasites, bacteria, or viruses.
Water treatment plants can also disinfect water using ultraviolet (UV) light or ozone. The treatment is crucial for human health and the environment.
Revolutionizing Water Treatment for a Cleaner World
Wastewater, also known as sewage . Water that has been used and contains impurities. It’s generated after the use of freshwater, raw water, drinking water, or saline water in various applications or processes.. The treatment process can involve various methods, including physical, biological, and chemical treatments.
Wastewater can be a sustainable source of water, energy, nutrients, and other recoverable materials if managed properly. Therefore, improving the way we manage wastewater can help ensure safe and sufficient water supplies.
Towards a World with NO Water Scarcity
The Sustainable Development Goal 6 (SDG 6) is one of the 17 goals adopted by the United Nations in 2015 to work toward a sustainable and poverty-free world by 2030. Targets are universal and equitable access of water, access to adequate and equitable sanitation and hygiene and end open defecation, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity, implement integrated water resources management at all levels and implement integrated water resources management at all levels, expand international cooperation and capacity-building support to developing countries in water- and sanitation-related activities and programmes water harvesting, desalination, water efficiency, wastewater treatment, recycling and reuse technologies Support and strengthen the participation of local communities in improving water and sanitation management.
Solving the Water Crisis, One Drop at a Time
The water crisis is a global problem that affects millions of people around the world, especially women, children, and the poor. one to ten people lack access to safe water and one in four people lack access to a toilet. This disproportionately affects women, who are often responsible for collecting water, and children, who are often responsible for collecting water for their families. The lack of water and sanitation locks women in a cycle of poverty. Empowering women is critical to solving the water crisis. When women have access to safe water at home, they can pursue more beyond water collection and their traditional roles. They have time to work and add to their household income. The water crisis is also a health, education, economic, and climate crisis that can be solved with access to safe water and sanitation. It is a result of managing water badly and using it too much. It covers topics such as saving water resources, improving drinking water supply, improving transboundary cooperation, and reducing environmental and social conflicts.
Diving into the Depths of Women and Water
Water is a precious resource that is essential for life. Women and girls are disproportionately affected by the lack of access to safe water and sanitation facilities. Women and girls are more vulnerable to abuse, attack, and ill-health without safely managed water, sanitation, and hygiene services. In many parts of the world, women and girls are responsible for collecting water, which can be a dangerous, time-consuming, and physically demanding task. The global water crisis directly affects women, and responsible for finding a water resource in order for their families to survive, the water crisis for women is personal.Improvements to water, sanitation, and hygiene services at home, school, work, and in public spaces support gender equity. Women and girls must play a central role in designing and implementing solutions, so that services respond to their specific needs. Embedding gender equity into policy at all levels will be crucial to achieving water and sanitation for all, which in turn will help advance many other parts of the SDG agenda, particularly poverty reduction, health, education, and work.
The Impact of Thermal Pollution
Thermal pollution is the increase in water temperature due to human activities. This can affect water quality and aquatic life by reducing the dissolved oxygen level and disrupting the food supply of water creatures, promoting algal blooms that deplete oxygen and release toxins, altering the habitats and biodiversity of fish and amphibians that are sensitive to temperature changes, and changing the properties of water, such as density, viscosity, and solubility of gases .
Thermal pollution can be caused by various human activities such as power plants, industrial factories, and wastewater treatment plants. Thermal pollution can have a significant impact on aquatic ecosystems. Warmer water can cause a decrease in dissolved oxygen levels, which can lead to the death of fish and other aquatic organisms. It can also cause changes in the behavior and migration patterns of aquatic animals .To mitigate thermal pollution, industries can use cooling towers, which can reduce the temperature of the water before it is discharged back into the environment.
