Wastewater Treatment Plant
Wastewater is water that has been used and must be treated before it is released into another body of water, so that it does not cause further pollution of water sources. Wastewater comes from a variety of sources. Everything that you flush down your toilet or rinse down the drain is wastewater. Rainwater and runoff, along with various pollutants, go down street gutters and eventually end up at a wastewater treatment facility. Wastewater can also come from agricultural and industrial sources. Some wastewaters are more difficult to treat than others; for example, industrial wastewater can be difficult to treat, whereas domestic wastewater is relatively easy to treat (though it is increasingly difficult to treat domestic waste, due to increased amounts of pharmaceuticals and personal care products that are found in domestic wastewater.
Wastewater is produced by human activity and has a direct impact on the natural environment into which it is discharged, whether it is treated or not. The responsible management of the increasing volumes of wastewater represents a genuine sanitary and environmental challenge for all the players involved (local authorities, operators, etc.), all over the world. Efficient treatment solutions exist, including the possible reuse of treated wastewater.
