Catch basin: what is it and how do they work?

The catch basin for drainage is a modern, efficient drainage solution for the landscape system. This element, as a rule, includes a network of pipes that pass through the area and drain excess water. The water separator is usually connected to the water supply system, which transfers excess water to the sewage system or a special tank. You can find culverts in residential areas and commercial establishments. It is an excellent drainage solution that protects the ground from excess water. All drainage supplies actively use grids to collect water and debris. A reservoir can do wonders for removing excess water and preventing flood damage to nearby homes and businesses. The water flows down the inlet/outlet pipes to a new location. Drainage basins are necessary to remove excess water and melted snow and transport them to the nearest natural sources. As with all environmental solutions, they have pros and cons. Let’s discuss the advantages and disadvantages.



Installing wells in a residential or commercial space has many key benefits. Some of these include Improved landscaping: The trench design is self-contained and able to blend in with the rest of the landscape. They also effectively cope with the removal of excess moisture. Wet soil can lead to the breeding of insects, mold, and unpleasant odors. Cost: Addressing residential issues such as flooding and landscaping can make your property more attractive. Most home buyers and business owners prefer properties that do not require renovation. The installation gives potential buyers more confidence in the purchase and increases the price of the property. Flood Protection: One of its most important and beneficial uses is its ability to efficiently remove excess water and debris from your home or business. Flood damage can hurt your property, so finding the right drainage solution is only in your best interest.


While the advantages of installing a drainage system are great, it is important to recognize the disadvantages to make the right choice for your home or business. Some disadvantages: Drainage ponds are a great breeding ground for unwanted parasites and some bacteria. They effectively remove excess water during heavy rains. But if they do not have time to fill with water, the drainage can become clogged, garbage can accumulate. This can cause some problems, namely damage to the pipes. This is a serious situation that needs to be fixed. Be sure to hire a professional who can repair the system and reinforce it with reliable material for a stronger structure. While it may seem like there is only one type of catch basin, it is important to consider the two most common types for homes and businesses. From the drainage pipe, water flows into the catch basin, from where it can be removed from the site, filtered, and redirected to an artificial reservoir or used for irrigation. Initially, the catch basin was built from concrete rings. It was necessary to perform complex earthworks. Special equipment is required to install the rings. At the moment, it has been decided to abandon concrete structures. They have been replaced by capacious containers. This catch basin can be set manually. A hatch is installed in the upper part of the container, which hermetically closes the catch basin. Connection to the drainage system and drainage is carried out through connecting nodes. It should be remembered that the drainage system will cost less if it is laid during construction. Installing the system around an already erected building will complicate geodetic measurements and increase the amount of work.

Option 1

The catch basin mine of the first type is usually rectangular or circular, depending on the quality of the material, containing about 1.5 meters of pipe. A catch basin of the first type may be suitable for residential construction, as this option can hold a small amount of water.

Option 2

This option is designed for larger pipes but can go as deep as 15 feet, so they may be more suitable for commercial establishments. When installing the second type of catch basin, be aware that there may be other aspects that personnel should be aware of. Many people confuse a catch basin with a French drain. However, both have unique characteristics that set them apart from the rest. A French drain refers to a drainage solution in which water enters through the bottom or drains from the top, allowing moisture to escape through pipes. French drains are great for water level control. In contrast, a catch basin is a simple underground box that helps reduce flood damage by channeling water underground through drainage pipes.

How to install a catch basin?

If we install a sump on the ground, it is very important to analyze the area, consult with an engineer, study the drainage system, and plan the project well. Drainage basins are standard equipment on public roads, but when installed in a residential area, contractors must place them at the lowest point of the site. In many cases, improper placement of the drain pan can clog the drain pipe and render the system unusable. Remember to keep the team informed of any changes that occur throughout the project to ensure a successful deployment process that frees up space efficiently. When filling, it is important not to damage the pipes. The backfill is covered with a layer of geotextile (filter fabric) and a layer of fine sand is poured on top. Sand will ensure good water permeability of the drainage system, and geotextiles and gravel will protect the pipes from clogging. From above, the hole is covered with pre-dug earth. To increase the efficiency of the system, you can fill the trench with soil with high water permeability.

Service tips

Be sure to clean the oil pan regularly to avoid excess water and debris. If the catch basin is not cleaned for a long time, odors and dirt may appear, which may cause inconvenience to guests and customers. To clean the catch basin, lift the grates, and remove water and debris with a shovel and bucket. Make sure you drain the excess water into a proper drainage system. The drainage system ensures a normal indoor climate, protecting the house from fungus and mold. The drainage system ensures the safety of the foundation and prevents possible flooding of basements. There are two main types of such drainage systems: the first system is used when the groundwater lies at a shallow depth. This means that the base of the building is on a waterproof layer. This type of drainage collects and drains water that goes directly to the foundation, thereby limiting the level of its accumulation. For this purpose, a special drainage pipe protected by filter backfill is laid around the perimeter of the entire building. The depth of the lift should exceed the floor level of the house. The drainage system of the container is located over the entire area of the building and forms a kind of cushion. Such drainage guarantees the protection of all underground parts of the building from flooding with groundwater and protects against moisture. Installation of such structures must be carried out directly at the stage of building construction, this work must be foreseen in advance during the development of the project. It would be best to combine both systems into one combined system. In this case, the container drainage will protect the floor from groundwater, the wall drainage will divert surface precipitation away from the walls and foundation. When you want to use one type of drainage, it is necessary to conduct a hydrogeological study to determine the type of soil, the depth of groundwater, the amount of precipitation, and other important factors. Based on the received data, specialists can determine which type of drainage will be most effective in your case. In the case when the house is already built, and there is no drainage system, a pit structure should be used. In this case, the drainage pipe is located along the perimeter of the building at a certain distance. Depending on the depth of the foundation, the type of soil, and the level of groundwater, the optimal depth of the functioning drainage system is determined. The reliability of the structure can be increased by creating several drainage rings at different depths. Due to the design of the type of drainage pipe, it reaches a waterproof layer. It is possible to determine which design will be the most effective in each specific case only after carrying out special studies of the soil and groundwater. Drainage works begin with an assessment of the type of soil, depth of freezing, dimensions of the foundation, and several other key factors. The key parameter is the depth of pipe laying. It is worth considering that they must be placed at a certain angle, otherwise, the system simply will not work properly.
