All you need to know about Storm Water Drains

A stormwater drain is specifically designed to drain excessive ground or rainwater from surfaces which are impervious such as car parks, parking lots, paved streets, sidewalks, footpaths and roofs. These drains help in preventing flooding of the streets as they transfer the rainwater to the natural bodies of water, so they lead to streams, watersheds, rivers oceans, lakes and more.

Storm Water Drainage Design: Proper layout and planning is necessary

Stormwater drain

• Retain water on the property for use in the gardens and the filtration systems.
• Slow down the flow of water to prevent flooding or problems related to erosion.
• Reduce the labour and cost of unblocking drains.

Besides this you also need to consider the following factors including the following:

• The depth of water table. If it is too deep, then plumbing would be a problem.
• Type of soil and depth. In soft soils, water can percolate easily and drainage would not be a problem, but in rocky soils, drainage and plumbing can be a bit problematic.
• regulations of the council and aspect of slope

A building of Storm Water Drains:

These stormwater drainage systems are made of major and minor systems which are designed for the calculations based on storm events. The main functions of the minor systems are removing water from roadways, streets and sidewalks. These systems are made of a network of pipelines which are connected through underground pipes, ditches, channels, swales and gutters. Once the capacity of these minor systems crosses the limit, the major systems take over.

Purpose of Concrete Storm Water Drain Structure:

Most of the equipment used for a concrete storm drain structure is not visible as it is positioned underground. In the interstate systems, drainage systems are concealed behind the embankments. Places which do not have the apt drainage systems can face the wrath of floods as there is no place for the rainwater to flow.

Working on Storm Drains:

The rainwater is pulled down by means of gravity into the pipes laid underground. These systems are installed in areas are constructed at an angle which is tilted for allowing the water to flow in the downward direction.

Grates of Storm Water Drains:

The mesh screens and grates in these systems play an important role in managing the excess water. They can restrict litter, trash and other objects from entering the drains and creating a clog. Besides this, they tend to be a safe passageway for vehicles and people. The design has to thus balance some factors which include

1. Size of Aperture: The size of the holes needs to be neither too small nor too big. They should be of a size which can prevent litter and trash entering but big enough for the water to flow in easily.
2. Rating of the Load: For this, you need to consider the amount of load the grate needs to bear. Does it have to bear the weight of only the pedestrians or also of the cars, trucks and other vehicles?
3. Shape and size of Aperture: This should be able to cater to wheelchair users, cyclists and probably even high heels.

Opting for Storm Water Drains:

These stormwater drains need to be handled by only experts as there are too many complicated factors to be considered.

You can conduct an online search for the requirement of stormwater drains and go through the different websites offering these services.
