All You Need To Know About Stormwater Retention & Drainage Pit


 A stormwater retention pit and drainage pit is a great way to manage stormwater runoff. Stormwater drainage pits, also known as rain gardens, help to manage water where it falls. A stormwater retention pit is used to collect surface water runoff from a property. They can be used in conjunction with rain barrels, rain gardens, or other landscaping features. The planting area of the stormwater retention pit can be used to grow plants that are adapted to wet conditions. The overflow from these pits is typically directed into other areas of the landscape.

They work by retaining water so that it can be absorbed by the soil or evaporate into the air, instead of running off into storm drains and polluting waterways. They can also be used for erosion control and as part of a rain garden and to prevent flooding.

Who Should Install Retention/ Stormwater Drainage Pits?

Retention/drainage pits are relatively simple to install and do not require special skills or equipment beyond what is typically found at home improvement stores or rental shops. If your project requires more than one person to complete it, it is recommended to hire a contractor or licensed landscape professional with experience in installing these types of projects.


Stormwater drainage pits are often located in areas where there is a risk of flooding or erosion as they help reduce the impact of heavy rain.


Process & Materials Used For Stormwater Drainage/Stormwater Retention Pits

Stormwater retention and drainage pits can be made from many different materials depending on their size, intended purpose and location. They are usually designed with a sloping edge so that the water drains out of the pit through pipes at its base. The pipes may lead directly into a soakaway or soakaway chamber which will then discharge into an underground pipe network.


When designing your stormwater drainage pit, consider the size of your yard and what you want to use it for. You will need to determine how much area you have available for your pit and how much water you want it to hold. For example, if you have a small yard but want to grow vegetables, then you may only want to use a shallow pit for collecting water from rain storms.


You will also need to decide how deep you want your pit to be. This is because deeper pits can hold more water than shallow ones, but they also require more work when digging and building.


The choice of material for your pit depends on what you want it to do and where you want it to go when it rains. For example:


-If you're building an underground pond then you'll need something that will withstand being under pressure for years at a time without cracking or collapsing


-If you're using it as part of your garden then you might want something that looks pretty in your garden rather than just being functional.

The main components of a stormwater retention pit include


-A shallow depression in the ground with sides sloped at about 2:1 (2 units high for every 1 unit wide).


-An impervious bottom material that prevents soil loss and provides structural support for the sides.


-An outlet pipe that drains excess water away from the site.

Finally some of the main benefits of Stormwater retention pit/ Stormwater Drainage Pit

-Stormwater ponds help prevent flooding by absorbing excess rainwater.


-They reduce soil erosion by slowing down the speed of water flow.


-They are low-maintenance since there is no need for pumping or treatment. They also don't require a lot of space or money because they can be built on-site without professional help.


-They're good for wildlife because they provide habitat for animals and plants, including insects and amphibians.


Now that you know the basics of these drainage and water collection systems you can decide for yourself if building one is the right choice for you.
