Stormwater Management System

Stormwater Management System

About 70% of the earth is made up of water, which implies that rainfall activity will often happen when you consider evaporation. Since humans are the most dominant species on earth, it is necessary to make the environment habitable for everyone living in it. Stormwater originates from rain, melting snow, or ice. The stormwater usually finds itself infiltrated in the soil, held onto a surface, and evaporates or run-off into nearby water bodies. Before industrialization, majority of stormwater was either soil soaked or evaporated. But nowadays, rainwater harvesting has made it possible to funnel stormwater into streams, rivers, and lakes.

What is stormwater management system?

This refers to a structured system of ensuring that at a surface level, stormwater harvesting is designed and constructed to collect, store, treat, use or reuse water with the aim of flood prevention, water pollution, over drainage, and other related water disasters. Stormwater retention systems also take into account the drainage designs of cities and commercial stormwater detention services for housing developments and other commercial facilities.

What is the goal of stormwater management system?

Stormwater detention solutions aim to protect the environment, reducing flooding to the barest minimum, which will help to safeguard people’s lives and properties. There will be less demand for public stormwater drainage systems when rainwater detention is successful. That way, there will be cleaner streams and rivers to create healthier and more sustainable communities.

It is abundantly clear that no system is without some disadvantage, no matter how perfect it may be. Here are some pros and cons of stormwater management systems.

Pros

  • Stormwater management system ensures that water surface run-off is funneled into the drainage properly.
  • With a well-structured stormwater management system, it is possible to recharge groundwater and reuse precipitation water to irrigate or even as water for the household.
  • An effective stormwater management system makes it possible to treat water early.
  • Stormwater management system prevents infrastructural damages by helping to reduce flood to the barest minimum.
  • With proper channeling, stormwater management systems can improve urban landscapes and provide the needed resources for a green or recreational area.
  • The advantage of below-ground closed systems is that they can be protected from freezing as it is concealed from view.
  • For above-ground closed systems, it has minimal capital and maintenance costs and can be fed by gravity.

Cons

  • To get a near perfect stormwater management system, there is the need for proper planning and implementation involving experts. Also, the high-level manpower required for operation and maintenance can be daunting.
  • It requires a lot of technical know-how. Also, the operational and labor costs are discouraging.
  • If it is not properly constructed, stormwater management systems can attract the risk of clogging, which is often a consequence of high sedimentation rates.
  • Below ground closed stormwater management systems require pumping and a stronger structure if located in traffic areas. Plus, it costs a lot of money to be constructed and has a higher maintenance cost.
  • Above-ground closed systems come with aesthetic problems and are more likely to bend to weather conditions.
