Storm Water Detention

A stormwater detention tanks is a structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. These tanks are considerably less expensive and easier to maintain year over year than a conventional detention pond.

Storm water is any form of precipitation, including rain and snow melt that has come into contact with the earth, or any other surface. This water will evaporate, seep into the ground, or be absorbed by vegetation. If it doesn’t, storm water will become surface runoff, flowing off the land and into storm drains, streams, rivers or lakes. Storm water can come from all types of land, whether it is agricultural, residential, industrial or commercial. To help prevent flooding and can reduce erosion in rivers and streams. They do not provide treatment to improve water quality, though some are attached to a media filter bank to remove pollutants. Stormwater detention allows for high volume storage of runoff in a small footprint area.In an environment uninterrupted by human development, water is naturally processed through the water cycle. The earth’s atmosphere continually absorbs water from the earth’s surface, purifies it and then precipitation returns it to be used for vegetation growth. Eventually the water is once again evaporated and the cycle begins again.

Storm water can be very problematic. Due to the volume and timing of the surface runoff water and secondarily, due to the potential pollution that it may be carrying. When human development alters the surface of the earth (with the addition of hard surfaces, such as roads and buildings) we are inevitably interfering with water’s ability to be absorbed back into the soil. In essence, we are interrupting the natural water cycle.The need for effective strategies to prevent storm water pollution and process storm water in a way that returns it safely back to the natural water cycle, is becoming increasingly recognized.There are many advantages to using Detention Tanks as a means of storm water management. It supports environmental sustainability by diminishing the creation of polluted storm water thus reducing the environmental impacts on lakes, streams and rivers.
