Storm drain contractors are involved with the installation process of subsurface pipes. These systems are necessary for redirecting water flow to reduce the risk of flooding in residential communities, along interstate systems, and surface areas such as parking lots and sidewalks.

Using the services of storm drain contractors is required with all types of pipeline construction jobs including municipal, institutional, industrial, commercial, and residential. Storm drainage systems are crucial for getting rid of storm water runoff that collects on ground surfaces and could result in flooding.

Storm drainage systems are comprised of catch basins and inlets that are strategically placed along curbs, roads, and sidewalks to redirect storm water runoff to subsurface pipes. These pipes transport excess water to an outfall opening so that water can be discharged into open bodies of water like rivers and oceans.

Fireline contractors play an important part when it comes to public safety. This type of pipeline construction involves installing water pipes that connect to fire hydrants and indoor sprinkler systems. It also pertains to carefully inspecting pipes to ensure they are in good working order and free from defects that could reduce water pressure or cause accidental flooding.

Due to the nature of the work, fireline contractors require a significant amount of training before they become licensed. Most states require laborers to work as an apprentice under the tutelage of a licensed contractor.

Wet utility contractors are involved with many jobs related to subsurface pipeline. In addition to installing new sewer and water pipes and storm drainage systems, contractors also repair or remove pipes; prepare worksites for demolition work; and restore jobsites once pipeline work is completed.

Wet utility contractors also are involved with installation and repair of municipal water treatment systems, steel tanks, and pre-cast pump houses along with updating deteriorating freshwater pipelines.
