What are their benefits and potential environmental impacts?
Waste water is any water that has been affected in quality by domestic residence, industrial, and agricultural wastes that leads to presence of wide range of potential contaminants in water. http://en.wikepedia.org/wiki/wastewater. Planning for wastewater treatment and disposable facilities is a challenge for each community. This treatment leads to protection of public health, protection of water resources and growth of community.
Nowadays, people know that they should give nature their support and collect waste water to increase property value, protect wild life and fish and allow many recreational activities to be enjoyed on the water or on the surrounding environment.
Thus we can talk about the main advantages of wastewater treatment:
1. Saving of extra water.
2. Recycling of water.
3. Ground water, surface water source is safe from pollution due to treatment of waste water.
4. Farmers can use treated water for vegetation.
5. People can save cost of transformation of polluted water.
“The major environmental benefit from reusing waste water is a reduction in pollution of waters receiving discharge of sewage. Reducing the volume of this discharge is also a powerful driver for wastewater reuse”. WasteWater Reuse: Environmental Impacts And Risk Assessment (Stagniti, Hamilton, Versace, Idiaconou)
Sewage is part of waste water that is contaminated and there are significant advantages to sewage treatment accruing both humans and natural environment. Regarding to people, the most significant benefit is to decrease waterborne disease because streams enter in drinking water. With regard to ecosystem as a whole the benefits are demonstrated by retaining t...

...is found in wastewater, including bacteria viruses and worms. The symptoms and diseases associated with such infections are numerous for instance Typhoid and diarrhea. The concentration of pathogens in wastewater is dependent on the source population and it varies from one population to another. Human impacts on freshwater systems are substantial in most populated parts of the world. Substitution of wastewater with fresh water is beneficial and has been promoted because it reduces anthropogenic impacts . .

...wastewater is sewage plants or sewers, since many areas dump their sewage in the ocean. Sewage does have nutrients like nitrogen and other things some organisms may need to grow.
It is imperative that domestic water provided for direct consumption and ingestion through food must be sanitary. Scientific research indicates that as many as 19 million Americans may become ill each year due to parasites, viruses a...
In the ancient world there was an awareness of the need for sanitation and for water that was safe for consumption. Efforts at keeping water pure, maintaining access to waters of high quality, and providing sewage disposal were widely practiced. With the diminish of the Roman Empire and the beginning of the middle ages, these practices were largely forgotten, and infectious illnesses became common. Only with the ascendancy of the scientific method and discoveries in the last one hundred years has the connection between water quality, sanitation, and health once again been discovered.
Between 300 and 400 million people worldwide live in areas near wetlands and depend on them. Wetlands are mechanisms for treatment of wastewater are extremely efficient because they absorb chemicals and filter pollutants and sediments. Half the world's wetlands have disappeared due to urbanization and industrial development. The only way to achieve sustainable development and poverty reduction will be through better management of rivers and wetlands, and the land they drain and drain as well as through increased investment in them.
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Some people may not know this but wasting water affects our environment. Whenever water is wasted it ends up in treatment facilities. We need water to survive yet people still waste it because to their understanding there will always be water whenever they turn on a faucet. This is one of the main reasons that water is wasted. People often waste more water than they use. “Australia uses on average 500 litres per person per day, European countries using between 200 – 400 litres and the UK using about 150 litres.” This quote from the article, “Water Conservation” explains how not just in the US but all around the world people are wasting significant amounts of water every day.
Waste water treatment plants are essential to communities of all sizes and must work efficiently. Waste water treatment plant primary priority and responsibility is the treatment of incoming sewage water by the removal of biological and chemical wastes so it can be treated and recycled for future use. There are many government agencies and standards set forth to govern and observe the successful treatment of sewage such as: the Department of Environmental Quality, the National Pollutant Discharge Elimination System and the Clean Water Act of 1972. Compliance and constant monitoring of the treatment plant’s operations are important; as they protect the surrounding community. A spill or backflow of sewage due to a complete system malfunction could potentially be detrimental to the environment and local community. A precise system, of which must be compliant according to government standards, is critical to maintain low levels of wastes that are returned to neighboring water systems after treatment.
The increasing demands of clean water in the developing countries, threaten the biodiversity and human needs to survive, towns and cities in such countries are under a severe environmental stress. Cities have grown over past decades due to migration, increase in trade, tourism, and other activities. This created over population in urban areas more than they could handle. Drinking water and sanitation facilities are being hard to provide for the high number of citizens. The water supply and sanitation systems in these urban areas are usually have the following issues:
The consumption of contaminated water can be dangerous for health reasons and several people have passed away from these water-borne diseases. Some of these diseases include Cholera, Typhoid, Dysentery, Giardiasis, and Malaria. These unfortunate diseases are currently the cause of numerous deaths, especially in small children. The availability of clean water can prevent many problems in low-income communities. The available resources for clean water are very rare, so these water sources need to pass through a process of water sanitation in order to just be sustainable to drink, “The world’s surface is made up of approximately 80% water, which is an indestructible substance.

...rectly or indirectly discharged into the River Ganga” (KUMAR 12). In the analysis of the water countless amounts of harmful bacteria were found among them; Salmonella Typhi which causes Typhoid fever in men, B subtilis which can contaminate wounds and, Clostridium perfringens the main bacteria behind gangrene and food poisoning (KUMAR 8).These harmful bacteria have claimed numerous lives and yet the river is still being used for drinking and bathing. . The Ganges is still only one of thousands of other extremely polluted rivers, some of which are here in the United States.
Untreated sewage can contaminate the environment and cause diseases, such as diarrhea. The sewage is mainly biodegradable and can be treated in water treatment plants, but it is a major problem in countries that are not quite developed yet.
Wastewater can be a fancy term used for the water that has been adversely affected by human activity like dishwashing, fertilizing crops, bathing and flushing the toilet.
Water pollutants are of different types such as oxygen demanding wastes, disease causing agents, synthetic organic compounds, plant nutrients, inorganic chemicals and minerals, oils, thermal discharge and radioactive wastes. Of all these water pollutants, heavy metals and synthetic organic compounds cause majority of water pollution. Industries like paper and pulp, tanneries, textiles and coke ovens, pha...
Wastes are the products of our consumptions in our daily life routines such as lunch, work, school and other things we do. Little things such as throwing out a piece of paper, we are producing waste by the seconds. After we consume a product we usually throw out what’s left that can’t be consumed any further. Results in producing waste, substance that are born after it’s been use or consume by us. At the end of each day we throw out a bag full of garbage, all of the materials in that bag (paper towels, cans, leftover foods and many other material’s) all of these are waste. Hospitals produce medical waste such as use needles for treating patients. Corporations produce papers, plastics, tires, steels, cans and many other type of solid waste which contribute to the pollutions that cause health risk and other environmental issues.
