Storm Drainage System

Reduce Pollutants into American Waters

A storm drainage system is a complex unit that requires careful engineering by a civil engineer and proper installation by a licensed pipeline construction company. Drainage systems are an essential element in all facets of construction including residential, commercial, industrial, and municipal projects.

A storm drainage system includes a series of pipelines and related structures that carry storm water to the point of release. This system reduces environmental impact, such as flooding, that could result in land erosion and property damage. Storm water that accumulates from buildings, roads, and parking lots is gathered into the drainage system and transported through water pipeline until it can be deposited into retention ponds, lakes, rivers, and the ocean, or detention ponds positioned in low-lying areas.

Storm water is often polluted with litter, petroleum-based products such as oil and gasoline, pesticides, and eroded soil. If polluted storm water reaches waterways it can be harmful, perhaps even fatal, to aquatic life. It is estimated by the U.S. Environmental Protection Agency that storm water runoff is responsible for over 30-percent of pollutants in American waters.

One method for removing pollutants from storm water runoff is filtration systems, such as detention ponds. This type of pond is typically designed by a hydrologist and can either be a dry detention pond or a wet detention pond. The primary use of wet ponds is to treat storm water. However, these ponds tend to provide a good habitat for small mammals and birds which also make them a suitable wildlife preserve. Dry detention ponds are used to store excessive storm water runoff for gradual release into larger bodies of water or into the ground. Wet and dry detention ponds help to filter pollutants before water is released.

Every storm drainage system involves the installation of pipelines to transport water that needs to be discharged. Storm drainage pipes can vary in size ranging from 4- to 114-inches in diameter. Before pipeline construction companies can install storm drainage systems they must engage in data collection to plan the layout of the system. This includes: locating the main outfall; determining the direction of water flow and percentage of fall; locating manholes, connecting mains - all with the assistance of engineered survey staking.

Observing existing utilities surrounding a proposed new pipeline installation is another way to collect data. Pipeline contractors may choose to utilize subsurface utility engineering (SUE) to determine the location of existing utilities. SUE is a valuable technology that can minimize risks created by inaccurate underground information and therefore reduce overall project costs.

Civil engineers, who design wet utility pipeline systems, have to consider numerous factors when planning drainage systems. A few of the most important include: types of water pipeline required for the project; location of detention ponds for discharged water; location of inlets to collect water runoff; inlets and trunk line capacity; and the amount of time required for runoff water to reach the inlets.

Kana Pipeline has been closely involved in the installation of new storm drainage systems for over 25 years. We have extensive experience working with most types of filtration systems including: filter fabric, fossil filters, geomembrane liners, storm water filtration units, storm water chambers, bioswales, detention and retention drainage systems and underground stormwater storage tanks for landscape use - all that minimize the level of pollutants that enter our nation's waterways.

Kana has experience installing all types of storm drains required for commercial, industrial, institutional, municipal, and residential projects. We invite you to watch our storm water storage systems video to see us at work, as well as peruse our website to learn more about Kana Pipeline and the services we provide.
