Storm Drain Contractors

The job of storm drain contractors involves installing underground pipes to redirect water flow and prevent flooding on surfaced areas. Storm water runoff management is vital along interstate systems; within residential communities; and in areas with substantial commercial or retail buildings.

Storm drain contractors oversee projects related to all construction categories including residential, commercial, institutional, industrial, and public works. These systems are essential for eliminating storm water runoff that accumulates on ground surfaces such as streets, parking lots, and sidewalks.

Storm water drainaiage systems are not connected to sewer pipeline that convey wastewater to treatment facilities. Instead, systems are comprised of inlets or catch basins that are positioned along sidewalks, curbs, and roads to redirect runoff to underground pipes. The pipes convey water to an outfall opening where excess water is released into a larger body of water such as a pond, river, or ocean.

Improper installation could result in catastrophic events including flooding and release of environmental toxins or hazardous materials into water bodies. Therefore, contractors are required to undergo extensive training and pass an exam before they can be licensed.

Contractors are required to comply with the Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) permit program. NPDES focuses on regulating point sources, such as pipes and man-made ditches that release pollutants into U.S. waters.

Contractors that install or repair storm drainage systems for individual homes connected to municipal systems or septic tanks are not required to obtain NPDES permits. Contractors conducting work at municipal, industrial, institutional, or commercial sites must hold appropriate permits prior to breaking ground.

Storm drain construction also involves installation of filtration systems to lessen the level of pollutants that enter waterways. These can include fossil filters, filter fabric, geomembrane liners, storm water chambers, and other kinds of storm water filtration units.

Design engineers consider numerous factors when developing drainage systems. They need to calculate water flow rates and water accumulation rates to figure out pipe sizes and most efficient discharge point.

In some instances, contractors need to build detention ponds to hold excess water until it can be conveyed to another location. Detention ponds are beneficial for controlling the peak flow rate at outlet pipes and help to protect properties positioned downstream of the drainage system.

Municipalities govern allowable storm water flow rates. If water rates exceed permissible levels it has to be redirected to a detention pond or storm water retention pond until it can be released at the nearest watershed.

Municipal and industrial jobs can call for drain pipes as large as 114 inches in diameter. Installing these massive pipes and synchronizing each of the components requires years of experience and training.

Regardless of the size of the job, it's crucial to work with skilled storm drain contractors experienced with the specific type of installation process. Contractors need to have adequate insurance, licenses, certifications, and permits as required by the jurisdiction of the jobsite.
