Catch basin installation is a vital component to any landscape drainage setup. These grate-covered boxes are available in a range of materials, sizes and are placed in low areas where excess water collects to prevent any drainage problem in the yard. Water and solid particles flow into the box, with the solids settling in the bottom. As the water level rises, it reaches the outlet trap and flows into the local sewer system or watershed.

How to Install a Catch Basin
Installing a catch basin
, or any drainage system, can be strenuous work, and before undertaking such a project it is wise to consider hiring a landscape/drainage contractor. However, if you believe you are in good condition to install it yourself, it’s a fairly easy process.
- Choose your location wisely, in a low place where excess water easily collects. After choosing the location for your basin, mark it with spray paint. Then plot out the route for the piping and mark that as well. You’ll want the pipes to slope downward slightly.
- Next, begin digging the trenches. This can be completed with a trencher or with a trenching shovel, depending on the size of the project. Take steps to dig low and wide enough for your pipes, being sure to leave around 3” on either side of the drain pipe. Dig the hole for the basin next. The outlet should line up perfectly with the trench.
- Once your trench has been dug, the catch basin installation process begins. Before placing the basin in the hole, make sure you have installed the adapter or plug that will connect it to the pipes.
- There are two options for securing your basin: gravel/stone and concrete. Concrete offers better protection from distortion and generally extends the life of your basin, but can be more expensive and tricky to work with if you don’t have the experience. Concrete techniques include pouring into a mold before adding the basin and pouring the concrete around the basin.
- When using gravel or stone, add a layer in the bottom of the hole, then place the basin on the ground. Attach the basin grate using the correct screwdriver.
- After your basin has been installed, connect the pipes to the basin’s inlet and outlet. PVC pipes will be a press fit while corrugated pipes will snap in. Complete the pipe network, securing them with glue or tape where it’s needed.
- Before backfilling, you’ll want to test the drain system to ensure there are no holes or other problems. This can easily be done by pouring water directly into the basin or pipes.
- The final step in the process is backfilling the trench and holes. After replacement, the soil must be compacted well, because voids could cause the system to sink, and result in a drainage problem in the yard.
Your landscape drainage system can be improved exponentially with the use of catch basins. A properly installed and cleaned catch basin is a huge asset to any property.
