Things You Should Know about Storm Water Catch Basins

By Daniel Locke


Did you know that ancient civilizations used storm drain catch basins as a rainfall collection system to hold water through dry periods? Or, that catch basins also shielded vegetation against stormy seasons? If not, you are not alone, but it's fun trivia to know.

Today storm drain catch basins aren't needed for irrigation or rain collection. Instead, they protect towns against storm surge that can lead to flooded roadways and acreage. Areas that don't have storm water drainage systems are often subjected to severe flooding because storm water has no room to go.

The purpose of municipal systems is to capture rainfall and draw it into underground pipes. The majority of systems can process around one inch of rain every hour. Regrettably, they often become overburdened during tropical storms and hurricanes, but are still able to remove some degree of storm surge.

Civil engineers design construction plans which must be authorized by city planners. Substantial work goes into building storm drain structures. Engineers collect information about the job site to calculate positioning of system equipment and underground pipes.

Usually, engineers work with subsurface utility engineering contractors that utilize specialized technology to make maps of underground terrain. SUE equipment offers a range of benefits since it reveals any equipment buried under the surface.

Most people would be impressed by the way storm water pipes redirect 1000s of gallons of water away from their house and community. When civil engineers make construction plans for municipal systems they spend a great deal of time studying historical rainfall data. Knowing the pattern of storms helps ensure proper water management practices are established prior to installation.

Last, but not least, there are situations where engineers must develop blueprints for detention ponds. These water storage ponds are generally used in regions that do not have lakes nearby.

Detention ponds are classified as either wet or dry and are necessary to temporarily hold excess water. Wet detention ponds perform as a purification system, while dry ponds are used as a water storage unit.

The Department of Transportation manages issues and concerns pertaining to storm drain catch basins. Anytime municipal systems are in need of installation, repair, or removal city managers must hire specially trained contractors who are knowledgeable about EPA storm water drainage system practices.
