Catch Basin Replacement


A catch drain, also known as a curb inlet or a storm drain inlet, is an opening or inlet to the storm drain system, which comprises a grate at street level to act as the entrance of storm water to the catch basin. A sump traps sediment or debris and related pollutants. Many people often wonder what purpose catch basins serve. Well, catch basins work by preventing trash, debris and floatable materials from getting into the drain system through a hooded outlet. Catch basin outlet pipes on combined sewers are fitted with a flapper device to prevent the backflow of unpleasant odors coming from the pipe. In addition, catch basins act as pretreatment before applying other treatment practices by letting larger sediments or residue settle in the basin sump.

Why you should your replace catch basin

– Storm sewer blockage
– Highly polluted storm sewer
– Clogged catch basins

Step-by-step installation guide

1. Mark the area using a spray paint, especially piping and collection points and measure the run of pipe, noting the change in elevation between collection points
2. Based on the piping layout you marked, dig the trench using a trenching shovel. For slopes that require the trench to exceed 4’ deep, shore up the walls of the trench to prevent it from collapsing. Also, do dig a hole for your catch basins.
3. Install basins after adding 3” of compacted gravel in the hole. You may tape over the outlets and inlets of the basin to keep out debris such as concrete from getting into the basin. The next step involves installing selected grate on your catch basin
4. Connect pipes to the inlet and outlet of basin or grate and then connect the pipe network. Test the system by running water to ensure proper flow of water to the discharge point, checking for any leaks. If satisfied, glue the pipe and fittings together. Use duct tape for corrugated pipe.
5. Backfill the trench using the soil previously removed and compact it well to remove void spaces which can cause future drainage issues.

If this does not fix the problem what other alternative do I have?

1. Ensure the drainage system is designed and installed in such a manner that water flows downhill through gravity alone.
2. Check to ensure the piping network run down hill continuously until it reaches the discharge point
3. Ensure the grate locations are located at low points on your property.
4. Ensure the trench is dug with the required minimum slope

If this still doesn’t work, contact a professional plumber. It is important to replace catch basins to avoid storm sewer blockages, as the amount of debris and pollutants that enter storm sewers may eventually find its way into local waterways. Clogged basins may also flood parking lots and streets, thereby disrupting pedestrians, motorists, and businesses. Having a professional plumber performs this has the following advantages: a professional plumber has the knowledge and experience, as well as state-of-the-art equipment to test and install a catch basin, ensuring a properly functioning drainage system. Moreover, professionals follow industry standards during installation, repair and maintenance.
