Storm Drain Catch Basins

Did you know storm drain catch basins have been in use since ancient times? Long ago, early civilizations used drainage systems to collect water for their crops prior to dry seasons, as well as to safeguard crops from flooding during rainy seasons.

Although storm drain catch basins have evolved and are no longer used for crop irrigation, they are still used to protect communities against flooding. Without these drainage systems cities and towns would be underwater or constantly dealing with flood management.

Most people don't give much thought to these concrete receptacles positioned throughout neighborhoods and along city streets. It's unfortunate that residents aren't more mindful of storm drains. Instead, the lack of understanding results in people contributing to the water pollution problem.

Every time a person changes the oil in their car or has an anti-freeze leak in the driveway contaminants are washed down catch basins and ultimately down to the ocean. Animal waste, lawn fertilizers, pesticides, loose soil, and debris are also conveyed into the system whenever it rains.

The biggest challenge of drainage systems is utilizing any type of filtration device. Since systems are needed to quickly eliminate water during rain storms or rapid melting of snow, placing a filter inside would reduce the flow rate. Water has to be conveyed to underground pipes in expedient fashion; otherwise street flooding will occur.

Municipal storm drainage systems may include storm drain inlet filters used to remove oil from contaminated water. While it is an environmental crime to dump hazardous waste into storm drain chambers violators are usually discreet and make certain no one witnesses the act.

Few people realize that one quart of motor oil can pollute over 60,000 gallons of drinking water. Dumped or spilled oil adversely affects wildlife, plant life, fish, coral reefs, eco systems, and shorelines that in turn adversely affect all people that rely on the water source.

Everyone can do their part to reduce contaminants entering drainage systems by taking precautions to prevent spills and disposing of environmental waste properly.

Municipalities are responsible for performing regular cleanouts to reduce the level of toxic waste. Concrete storm drains may be vacuumed out at least twice a year, while the entire system undergoes ongoing maintenance.

The two kinds of catch basins used with municipal drainage systems are drop inlets and curb inlets.

Nearly everyone is familiar with curb inlets positioned throughout neighborhoods and along city streets. They are literally "in-lets" along a street curb that allows storm water runoff to enter the drainage system from the gutter. Most are hand-made with concrete, per specifications, that is, formed with wood and rebar, and may occasionally require a bar to prevent children and animals from falling in.


Drop inlet basins are more commonly found in coastal regions and low-lying terrain. They are also used in parking lots and underground parking garages. Storm water passes through the drop inlet in a waterfall fashion into the grated inlet before reaching subsurface pipes.

Storm drain pipe installation necessitates working with qualified and reputable contractors, such as Kana Pipeline. We've performed wet utility construction services in southern California since 1984.
