Redland Wastewater Treatment Plant
Redland Water is the department of the Redland City council that oversees the collection, treatment, and disposal of waste water in Redland City. Residential households and commercial premises such as shopping centers, cafes, commercial laundries, butchers, car-washing centers, and restaurants are the main sources of waste water in Redland City. Once collected, waste water is stored temporarily in abattoirs, before being released for treatment in one of the seven treatment plants located in Point Lookout, Dunwich, Mount Cotton, Victoria Point, Thorneside, Cleveland, and Capalaba (Redland City Council, 2012). The author paid the Capalaba Treatment Plant a visit, and found that the plant had just upgraded to a new waste water treatment technique referred to as the Vetiver Grass System, herein referred to as the VS. The Vetiver system, "a green and environmentally-friendly waste water technology as well as natural recycling method," had just been approved by the Queensland Department of Natural Resources and Mines, NRM (Ash and Truong, n.d.). Further necessitating an upgrade was the previous method's failure to comply with the new regulatory standards that had been established by the Environmental Protection Agency (EPA).
The plant's staff was just getting accustomed to the new treatment procedures and management found it necessary to compare the performance of the two systems so as to determine whether or not the VS was a perfect fit for the plant.
Capalaba Sewerage Plant
The traditional treatment scheme comprised of an Imhoff tank, three sewerage ponds, and a swamp area. Waste water from different quarters was collected in the Imhoff tank and left to settle. Large solids were removed through the process of sedimentation and the effluent first directed into the sewerage ponds before being left to overflow into the swamp area for disinfection. With the passage of the new EPA standards for pollution, the plant had to upgrade to a "system that would take up most of the water, as well as remove nutrients and heavy metals" (Ash and Truong, n.d., Para 2.1). Options such as rock filters...
Given water scarcity, the high costs of desalinisation and other unconventional methods of supplying water, and the pollution of surface and ground waters, Israel sought other natural supplies of water from the Litani" (Dolatyar, 2002). The Israeli then invaded Lebanon, but were met with extreme resistance. 1990 - Present - Period of return to bargaining tactic The fall of the Soviet Union, the Gulf War (1990-1991) and the interference of the
In a decade, as nations vie for this depleting resource, the global water industry is expected to be worth a trillion dollars a year. Another debate concerns the trade of "virtual water," where wealthy water-stressed countries purchase other nations' water in the form of food. Some see this as one solution to a multi-response requirement to the water shortage, but others see it as exaggerating the problem, since rural
25). Programs are also underway to increase riparian habitat and the perennial flow of water into the system (ADWR, p. 26). These measures will help to reduce the impact of the water shortage, but they will not be enough without the efforts of the citizens and daily conservation efforts. Arizona citizens must realize the seriousness of the water situation and must be willing to make lifestyle changes in order

While on one hand, the Nile gets the highest discharge from rainfall on the highlands of Ethiopia and upland plateau of East Africa, located well outside the Middle East region; on the other hand, discharge points of the other two rivers, Euphrates and Tigris, are positioned well within the Middle East region, prevailing mostly in Turkey, Syria along with Iraq. In other areas, recurrent river systems are restricted to
In the year following that incident, China's State Environmental Protection Agency (SEPA) announced a five-year plan to address the widespread water pollution issues, committing a budget of 125 billion dollars to that national effort (Pacific Environment, 2006). In 2006 alone, the SEPA responded to 161 emergency environmental pollution incidents, almost two-thirds of which pertained to water pollution (China Daily, 2008).
