Becoming Aware Of Stormwater Solutions

Stormwater management is the procedure or the act of dealing with the quantity and condition of stormwater. This includes structural or manufactured control devices and systems (such as retention ponds) for treating contaminated stormwater, and also operational or procedural practices. Management of stormwater is critical, particularly in urban areas where stormwater runoff is always a concern.

Stormwater is not just water which is brought by rains or stormy weather. The term covers all water coming from precipitation events, including snow or runoff water brought on by overwatering. Stormwater is of concern for two important reasons. One reason relates to the amount and time of runoff water (such as flood control and water supplies) and the other relates to the potential impurities the water is carrying.

In contrast to loose dirt or sand, impervious surfaces like car parking lots, roads, homes, and compacted soil never allow for rainwater to filter into the soil. This is why additional runoff water can be produced in metropolitan areas and urbanized places compared to rural or forested places. This really is unfortunate and can end up being detrimental to the environment. Rather than getting spent as runoff water, it might have replenished groundwater or supply stream base flow in dry conditions.

Stormwater management studies show that extra runoff may deteriorate watercourses, such as streams and rivers, and trigger floods once the stormwater collection system is overwhelmed with the additional flow. If not adequately maintained, runoff water from major or continuing rain may cause significant damage to lives and property.

Polluted runoff might result from toxins entering surface waters during precipitation events. It isn't as rare as one might assume. Routine human actions deposit impurities on the roadways, grass, homes, farm areas and other surfaces. These are grabbed by runoffs then ultimately wind up in rivers, wetlands and seas in significant amounts.

In certain regions, polluted runoff produced by roadways and highways may be the biggest source of water pollution. Other complications of polluted stormwater are stream erosion, weed invasion as well as changes to natural circulation patterns. Unfortunately, many native types depend on these patterns and circulation rates for breeding, juvenile growth and migration. Many stormwater management methods were created to get rid of pollutants from runoffs before they pollute surface waters or even groundwater sources.

Management of stormwater can be in the form of source control, so unsafe materials will be controlled to avoid release of contaminants into the natural world. However, natural rivers that remain or can be rehabilitated can be obtained and protected. Creating soft structures such as ponds, swales or wetlands to utilize pre-existing or 'hard' water flow and drainage systems (such as water lines and concrete channels) can also be effective in managing runoffs.
