Managing Stormwater: A Much-Needed System

Monsoon always brings about the risk of floods and the Sydney floods of 2021 were enough for people around the globe to understand the significance of a city’s drainage system to the safety of the city’s population. Poor management of stormwater threatens both property and the environment.

Before delving into the intricacies of effective stormwater management services,it is vital to discuss at length the meaning of the same.

What is Stormwater Management?

According to the United States Environmental Protection Agency or EPA, stormwater management controls the flow of excess rainwater or melted snow into lawns, roads, and similar places as well as improves the general quality of water.

However, it’s not as simple as it sounds. After heavy rainfall, the roads are usually eroded by the water and fill up the ditches and drains. This excess water is extremely toxic and naturally carries eroded debris, chemicals, pollutants into streams, lakes, rivers as well as other wetlands.

This is exactly where stormwater management services step in to save the day!

Components of a Stormwater System:

Stormwater systems can be easily classified into two groups,
Site Drainage – Any property like a residence or an office or even an industrial facility needs to deal with the rainfall landing on the site. The point is to effectively deal with the excess water from causing flooding or flowing into neighborhood properties. This might also involve storing the excess water temporarily in order to prevent it from overloading civil drains.

Site Drainage has the following components:
Storage tanks located underground
Storage tanks located above the surface
Rain gardens
Gutters
Hard surfaces
Soft landscapes

Civil Drainage – The whole function of civil drainage involves dealing with excess stormwater from around the city and discharging it slowly into the sea or similar water bodies. These drainage systems work within the environment and use natural water bodies like seas and lakes for discharging excess stormwater.

Civil Drainage has the following components:
Dams
Channels
Stormwater drains
Natural water bodies
Devices meant for improving the quality of stormwater

The Boon Of Stormwater Management:

In urban landscapes and developed areas, most surfaces like pavements and roofs are usually impervious and as a result, prevent rainwater or similar forms of precipitation from getting naturally absorbed by the soil.

Instead, the rainwater quickly runs into ditches, sewers, drains and ends up causing a number of issues like,
Damage of infrastructure
Overflow of sanitary drainage system
Erosion and flooding
Excess muddiness

Green infrastructure and an effective stormwater management system not only get hold of excess precipitation but also end up reusing it, thereby restoring the natural hydrology. The primary purpose of stormwater management services is to ‘detain’ the water and get rid of existing pollutants.

Here are some of the services that fall under effective management of stormwater systems:
Repair of the existing system
Design of new stormwater management system
Construction of all kinds of stormwater management systems
Pest control and management of vegetation inclusive of exotic species
Repair and installation of an aerator, catch basins, and pipes
Replacement of filters
Maintenance (scheduled) of both underground as well as surface stormwater systems

To Help Or Not To Help:

Most people living in residential areas in urban and developed cities have no clue as to stormwater systems and as a result most metropolitan cities today are a picture of mess and beyond control during heavy monsoons.

The first step towards a better lifestyle is awareness and accurate knowledge. It is normal to live in a residence of one’s own for years and not know about the building’s stormwater systems.

Here’s what any conscious citizen would do! It’s a two-step process really.

The first important thing is finding out exactly where the excess rainwater or melted snow flows on the property, in case all the water is not absorbed by the soil.

The next important step in this ordeal is to implement effective stormwater management services, thus reducing the loss of excess rainwater and making sure the water leaving the property is free from toxic pollutants and debris.

Effective and successful implementation, as well as management of stormwater systems, also require an accurate understanding of NPDES (National Pollutant Discharge Elimination System) permit requirements and unwavering cooperation between consultants, contractors, and staff.

Stormwater Management In Rural Areas:

Things are a little different in rural areas and on agricultural lands. More often than not rural areas face an increase in both flow rates as well as the volume of stormwater discharged. The two effects of an increased rate of stormwater flow are,
Floods
Erosion

The main problem that these areas face is the impermeable surfaces and the overflooded sewers, which in turn leads to erosion. Effective management of excess stormwater, however, can save this excess water that can easily be used for drinking and even agricultural purposes.

The stormwater management tools for rural areas are different from the ones applicable for urban areas. In rural areas, spate irrigation is extremely popular and so are other techniques like using field trenches, dams, and of course the most popular, rainwater harvesting.

All of these techniques always use bigger water bodies as sources and at the same time reduce the flow during monsoon while successfully storing the excess water for future use.

Conclusion:

It is natural for most stormwater management groups to always develop and implement various commercial, municipal, and even industrial programs and as a result, receive full compliance with any federal, state, and local stormwater rules and regulations, thus making it convenient for these groups to support any facility (city or industrial) with their stormwater management requirements. A much-needed necessity in 2021, while availing stormwater management services it is advisable to opt for groups with both experience and expertise in all phases of the same – from consultation and construction to regular maintenance and repair.
