To understand the need for stormwater management, it is necessary to understand what stormwater is. In its most simple form, stormwater comes from snowfall, rainfall, or other precipitation. Stormwater Adelaide does not refer to the runoff from roads and highways that temporarily reduce flooding, but rather the water that flows through city streets and gutters, feeders, ditches, and springs. It may also refer to water from inland lakes and rivers.
Stormwater is a significant concern for many people because of its potential pollutants. Stormwater runoff contains large pollution concentration pollution concentrations, such as lead, pesticides, bacteria, and bacteria that can pose serious health threats. As a result, many cities and municipalities are required by law to dedicate public funds towards prevention and cleanup of stormwater Adelaide runoff and contamination. In addition, construction sites are often required to use stormwater runoff containment systems to mitigate the effects of pollutants and contamination. These sites may include gutters, downspouts, eaves, and catch basins.
Stormwater pollution can cause a variety of problems for the environments in which it occurs. Sediment and contamination from stormwater typically occur when stormwater mixes with groundwater, whether on a private or public road or a stream or lake. This mixing causes sediment and other pollutants to enter the groundwater, resulting in detrimental effects for the natural ecosystem. This leads to more extensive deposits and other forms of pollution, such as solid wastes, chemical wastes, and solid fertilizer.
In general stormwater pollution refers to any waste or pollution caused by stormwater. This could include the discharge of industrial chemicals and other pollutants, vehicle exhaust, litter, and human waste. While human activities cause most stormwater pollution, natural events can also be generated, such as heavy rains or snow. Furthermore, the damaged infrastructure during an event may also act as a source of stormwater contamination. This includes leaking stormwater pipes, sewage treatment plants, and stormwater dams.
The primary method of stormwater pollution is a stormwater runoff to surface water and wastewater treatment plants. Stormwater Adelaide is usually disposed of in surface water bodies such as rivers and streams, although it can also be discharged into groundwater, the most valuable resource on Earth. Through discharge, stormwater pollution can cause ecological damage, including habitat loss and destruction of wetlands. Disposal also pollutes the environment through treatment, such as by disposing of sewage and stormwater in such places as stormwater troughs, septic tanks, and public treatment plants.
