3 Popular Methods for Stormwater Drainage
This illustration of 3 Popular Methods for Stormwater Drainage: below grade surface, on previous concrete, and exposed extension. Here’s a description and analysis of each:
Below Grade Surface Drainage
- This is the most common type of drainage system.
- It involves collecting water from roofs, gutters, and other surfaces and channeling it underground through pipes to a storm drain or other suitable outlet.
- Advantages:
- This method is hidden and can be more aesthetically pleasing.
- It protects the foundation of your home from water damage.
- It can be more effective at draining large volumes of water.
- Disadvantages:
- It is more expensive to install than other methods.
- It can be more difficult to maintain and repair.
On Previous Concrete Drainage
- This method involves collecting water from roofs, gutters, and other surfaces and directing it onto an existing concrete surface, such as a driveway or patio.
- The water then flows over the concrete and into a storm drain or other suitable outlet.
- Advantages:
- This method is less expensive to install than below grade drainage.
- It is easier to maintain and repair than below grade drainage.
- Disadvantages:
- It can be less effective at draining large volumes of water.
- It can cause ice buildup in cold climates.
Exposed Extension Drainage
- This method involves collecting water from roofs, gutters, and other surfaces and directing it onto an exposed extension, such as a splash pad or rain garden.
- The water then infiltrates the ground or is collected and stored for later use.
- Advantages:
- This method can help to reduce stormwater runoff and improve water quality.
- It can be more aesthetically pleasing than other methods.
- Disadvantages:
- It may not be suitable for all climates or soil types.
- It may require more maintenance than other methods.
The best type of drainage system for your home will depend on a number of factors, such as the size and slope of your property, the climate in your area, and your budget. It is important to consult with a qualified professional to determine the best system for your needs.
Here are some additional things to consider when choosing a stormwater drainage system:
- The amount of rainfall in your area: If you live in an area with a lot of rainfall, you will need a system that can handle large volumes of water.
- The type of soil on your property: Some soils are more absorbent than others. If you have sandy soil, you may be able to use an exposed extension drainage system. If you have clay soil, you will likely need a below grade drainage system.
- Your local codes and regulations: Some areas have codes and regulations that specify the type of drainage system that you can use.
