Globally, stormwater drainage is a significant problem for many homes and business owners. Stormwater will pool, flood, and cause several issues that no one wants to deal with if there aren’t one or more outlets for stormwater drainage.
Stormwater Drainage Systems
Thankfully, there are numerous approaches to dealing with stormwater, some more efficient than others. Here are five different types of stormwater drainage systems in case you’re planning to construct a stormwater solution on your property or are looking for a superior option to what you already have: Stormwater (rainwater) is transported to ponds, lakes, streams, and rivers by a network of buildings, channels, and underground pipelines. There are both public and private systems in the network.
It is a crucial component of the county’s system for managing storm runoff amount, quality, timing, and distribution. It is not a system component that transports water and trash from toilets, sinks, bathtubs, and other drains to treatment facilities where they are cleaned and treated.
Types Of Stormwater Drain
1. OPEN STORM DRAINS
Open storm drains typically run perpendicular to a neighboring road or perpendicular to a property’s edge. These pathways frequently lead water to a neighborhood sewer system, where it can be handled and treated. Open storms might be expensive to install, but once they are in place, they are typically inexpensive to maintain.
They are an excellent option for folks who want to gather surface water quickly and aren’t very bothered with aesthetics. Slopes towards open storm drains are possible in lots and paved areas. However, they are dangerous and call for the fence to prevent humans and animals from falling in. Additionally, they smell, which could even lower your property value.
2. SLOT DRAINS
A more recent development in drainage technology is the use of slots. They use long, narrow drain slots, which frequently span the whole length of a space. They work well for outdoor spaces that don’t need a lot of drainages, but when there is a lot of rain, they can flood quickly.
Due to this problem, slot drains are among the least efficient stormwater drainage systems. This drain makes outdoor spaces complicated to manage since water quickly overflows them, even with many slot drains installed. Light rainstorms and other conditions with low precipitation rates suit their use. Compared to different drains, they are also straightforward to clean and may be used for driving and walking without any problems.
3. FRENCH DRAIN
French drains are the best technique to stop water from gathering near the foundation of your house or other structure. These stormwater drains frequently use tiny grates close to a building’s foundation. The grates direct the water into long pipes that transport it away from the building’s edge and onto the street or a water retention basin.
The best thing about French drains is that their long pipes are almost always hidden by attractive stones or grass. They also make use of elaborate, gorgeous grates. French drains are excellent at removing water that collects close to a building’s foundation, but they are less successful in removing surface water from a larger area.

Who keeps the drainage system running?
The county is responsible for the dedicated storm drainage easements, including the public drainage system. The Virginia Department of Transportation maintains the storm systems in the public right-of-ways of the streets. Furthermore, private property owners are responsible for several personal plans, including driveway culverts and bridges crossing standard drainage systems.
Components of a system of storm drain?
Site drainage and city-wide civil drain systems are two types of storm drain systems. They consist of civil (town) and site components. Runoff from hard surfaces, including streets, sidewalks, and parking lots, enters drains through on-site detention systems (OSDs). These are run by municipal councils and result in more extensive catchments for stormwater. They eventually connect to cast iron or concrete pipes transporting water to various bodies and trunk drainage systems.
· Site Drainage
Any property, whether it be a house, an office building, a farm, or an industrial facility, must be able to handle the rain that falls on the property. Discharging surplus water flow effectively and preventing floods or runoff into nearby properties often necessitates channeling it adequately into the local drainage system. Additionally, it could be necessary to temporarily store extra water to avoid overtaxing civil drains (local creeks, the ocean, watercourses, etc.).
· Civil Drainage
Civil drainage’s goal is to collect stormwater runoff from the city and gradually release it to the ocean or other natural water catchments. Stormwater is frequently channeled and discharged using natural features such as lakes, rivers, and gullies via civil drain systems, which often integrate with the environment.
How does stormwater drainage for homes work?
Water naturally follows the shape of the land it falls on when it rains. Gutter drains and overland flow channels transport stormwater runoff to residential properties’ on-site detention (OSD) systems. These consist of several above- and below-ground pits and tanks that temporarily hold the runoff and regulate the rate at which it is discharged to the downstream drain. This water system’s goal is to lessen the likelihood that local lakes and rivers and the civic drainage system will experience flooding issues.
FAQs
Residential drainage systems come in four primary categories. Surface, subsurface, slope, downspout, and gutter systems are a few of them.
The two main drainage system options are French, and surface drains. Surface drainage systems are comprised of a few ground-level zones draining through PVC piping. When it rains, water runs into the plumbing and drains from the home through the drains.
The primary drainage system is a water-conveyance system that carries water to the outflow point from field drainage systems, surface runoff, and groundwater movement. The central drainage canal and a few collecting drains make up the primary drainage system.
