Stormwater flows from land to water sources, such as rivers and streams, during a rainstorm and tends to pollute or carry pollutants, including soil, sediment and water pollutants, to a landfill, waterway, or other waterway. Municipal stormwater management systems reduce the amount of stormwater entering a sewer or water supply.
What are some of the solutions to improving municipal stormwater management systems?
Sustainable solutions to municipal stormwater management include controlling and treating stormwater flows and managing stormwater systems, such as stormwater ponds or detention ponds, in a way that enhances and improves quality of life in communities. By reducing pollution and water losses to the surface of the waterway and providing treatment for polluted runoff, cities can significantly reduce health risks. Urban stormwater management systems are beneficial in that they allow for water treatment facilities and other infrastructure to be located in a central location in a municipality.
Stormwater ponds can capture stormwater, protecting both properties and residents from flooding. Depending on the size of the pond, residential property owners can cover or reduce the height of a proposed stormwater pond or capture it with a landscaping project. By recycling stormwater, stormwater treatment ponds can provide valuable water resources for municipal systems.
In addition, cities may choose to put on their management system a combination of stormwater ponds, stormwater treatment facilities and other means to reduce pollution. Some cities have realized that it is not feasible to provide sewer or water services to every property or house in their jurisdiction. Also, large, central treatment facilities may provide service to some areas but not others. That may not be enough to provide an effective solution to manage stormwater flows and reduce pollution. Local solutions to municipal stormwater management systems may include modernized city water and sewer systems,rooftop water collection systems, water-based bioremediation systems and biosolids management systems. Also, some municipalities may try to expand stormwater management service to unincorporated areas within their municipalities.
Stormwater management solutions and practices
Stormwater management solutions can include engineered or naturally occurring treatments, systems for integrated stormwater management within municipal systems and systems for decentralized stormwater management. Integrated stormwater management systems can have specific systems in separate or adjoining properties and manage stormwater either through traditional water-based solutions, artificial drainage systems or other water-based solutions. Systemized solutions use recycled water and additional reclaimed water to reduce wastewater discharge and organic discharge by using water-based solutions such as biosolids management or stormwater treatment systems. Municipal agencies have identified organic pollution control and treatment as a priority issue and treatment solutions are usually connected to other stormwater programs, such as sewage treatment, and municipal wastewater management systems.

Stormwater Runoff – Hidden water pollutants
The flow of storm water is one of the most serious threats to the environment today. According to the United States Environmental Protection Agency (EPA), 21% of damaged lakes and 45% of damaged mouths are caused by stormwater runoff. However, many people are unaware of this phenomenon and how they inadvertently contribute to this problem.
So what does it mean to carry storm water?
To understand why storms are destructive, one must first have a basic understanding of how the Earth’s water cycle works. In the earth’s water cycle, rain or storm water falls and is absorbed by various sources – porous soil, topsoil, body of water, plants etc. In the natural environment, nutrient water from these various sources “cures”. Natural process. Once “treated”, water evaporates again, forming clouds, and the cycle continues when rainwater returns to Earth.
Yet large-scale urbanization has led to the disappearance of natural ways to process water. For example, storm water absorption grounds have been widened for roads, parking lots and parking lots. These roads cannot absorb rainwater and they redirect water to the drainage system. That drainage system does not process the water and it only redirects to different parts of the water.
A similar situation occurs on the roofs of production facilities. Due to the various processes involved in production, pollutants such as grease and other substances evaporate from inside the facility and get trapped in the roof holes. Once it rains, these pollutants can be carried through the pores and the polluted water ends up in the storm drains. Unlike road drainage systems, these storm drains do not always have treatment systems and unprocessed water goes into ponds or drains.
How to stop storm water?
Of course, it is unrealistic to say that all roads and other surfaces that impede storm water absorption should be removed. Instead, several methods can be used to reduce storm water in streams, rivers and lakes.
One of the major methods suggested for industries is to install storm water flow protection equipment. There are many types available, from simple drain plugs and inserts to filtering machines and rooftop containment solutions. These not only control and manage storm water flow but also help protect property. In cases where roof preventive measures are not available, contaminants caused by the flow of storm water can also cause damage to the roof. A good example is grease, which can cause wrinkles, swelling and blisters on the bitumen membrane of the roof.
There are also many tips that ordinary homeowners can use to help reduce this type of pollution. Instead of using chemicals to remove snow from the driveway, for example, sand can be used as a suitable alternative. Fertilizer use should be kept to a minimum, as adding too much manure to storm water can lead to overgrowth of aquatic plants.
With these simple steps, everyone can contribute to reducing the flow of storm water and water pollution to help protect the environment.
