Before one realizes the need of stormwater drainage design, it is essential to understand what is stormwater and what are the affiliated concerns that give birth to its need. 'Stormwater' is the water originated through rain, snow-melts or can be the over-watering runoffs that land in storm water systems. The water that do not soak into the ground is usually the surface runoff water that is transported into storm sewers. As it is more of natural phenomenon, it may lead to two major concerns: rise in water pollution levels and unpredicted volume and timings of runoff water. Stormwater can carry the threat of potential contaminants along with it and can cause hurdles in flood control caused due to redundant volume and unexpected timings of runoff water.

It has been noticed that flooding destroys galore of properties and take lives of countless people in many towns and cities across the globe every year. This indicates how crucial is the need for flood control or a stormwater drainage design. A stormwater drainage design is made with an objective to prevent the calamitous results of flooding. With the aid of technical advancements, ...
... different methods of excess water control are formulated today and a design for stormwater drainage is the part of Storm Water Best Management Practices.

Storm water drainage design includes a set of drainage policies, design maps, analysis methods, stormwater runoff ways and design regulations utilized by a city as the formal plan guidelines for drainage betterment in accordance to the standards. A good design is what makes the entire difference between a flooding and non-flooding community. Deficiency of a good design can commonly lead to destruction of towns and agricultural areas in many countries worldwide.

Stormwater ponds are part of drainage design of developed or concrete areas mostly. These ponds roll up extra rainwater from all impervious surfaces like buildings, roads, gardens and parking lots. Soil absorbs water from non-concrete or undeveloped areas, scatter it to plants and trees and flow excess water into streams and rivers naturally. Thus, stormwater ponds serve similar purpose in concrete or developed areas. On the other hand, pollutants like fertilizers, dirt, oil, yard waste and litter produced by the day-to-day activities of people get collected on the retentive surfaces and seeps into waterways with rain. But installation of stormwater ponds can save habitats from harmful effects of these pollutants. These ponds can collect rainwater, deposit and enable pollutants to settle down before water being discharged back into the watershed.
