A parking lot drainage system is never an afterthought and should always get considered a necessity by landowners. Which approach is ideal for a particular application depends on several contributing factors, such as state, federal, and municipal regulations that pertain to parking lot construction. The government chooses stringent guidelines to control drainage systems due to erosion control and stormwater runoff that can impact the local wildlife, ecosystem, and drinking water supply.
Several drainage system options are available, and they work much like an insurance policy to help prevent disasters and protect against unsafe conditions that may prove costly. Determining which type of parking lot drainage system is ideal for a landowner will ultimately depend on the following:
- Frequency of inclement weather and storms
- Potentially pre-existing drainage systems
- The intensity of rainfall/runoff
- The type of application for the parking lot
- Type of drainage area
- Budget
The primary purpose served by drainage systems for parking spaces is to help remove stormwater quickly and effectively while having a minimal impact on the environment and traffic. Having a drainage system installed presents its fair set of challenges, so having a professional contractor gives peace of mind and assurance that the work succeeds to the highest standards.
What Are Common Types Of Drainage Systems?
Freeze-thaw cycles are probably the number one reason drainage systems are hard to control and install. The process can lead to cracks in the asphalt that causes the parking lot to deteriorate faster. Meanwhile, rainwater is naturally higher in acidity, which can further contribute to a quicker erosion rate.
A proper drainage system will contain ditches, channels, or inlets that help direct water flow to the city’s drain or sewer system. In an ideal setting, the construction of these systems happens before pavement. However, it is also possible to install it afterward for an additional cost.
Types of popular drainage options include the following:
- Catch basin drainage- considered an industry standard; their system uses a grate to catch any fallen debris. This classic design can remove materials that may impact flow and cause drainage problems. The water can settle before going through the system, and this design is considered the most affordable.
- Concrete-encased drainage basins- this next-level option uses extra reinforcements that allow the system to work well in high-traffic areas. This system best serves commercial properties, and though the initial investment is relatively high, it also lasts a long time.
- French drains- known for their aesthetically pleasing appeal- consist of a gravel-filled trench that sometimes does or doesn’t contain perforated pipes placed at an incline. It’s an inconspicuous option that allows landowners full leeway for landscaping and design.
- Trench drainage basins- perfect for large shopping centers and sports stadiums, trenches are employed to redirect the stormwater. These systems filter debris by using curb-opening inlets or grates while adequately directing water flow.
