Storm Drainage System

A storm drainage system is required to eliminate excess rain from homes, buildings, parking lots, and roads. Without these systems, communities would experience flooding every time a rain storm rolled through. A storm drainage system is essentially comprised of a catch basin or an inlet collection system, drainage pipe, and outlet pipes and other such drainage dispersal or outlet systems.

Catch basins include grated inlets that collect large pieces of debris and prevent them from entering the drainage system. However, smaller items can fall between the grate, so the catch basin is necessary to trap items that could interfere with the flow of water. Drainage pipes carry excess water to outlet pipes for discharge into large bodies of water such as reservoirs, canals, rivers, lakes, and oceans.

Residential areas consisting of homes older than 30 years are now finding they need to replace storm drainage systems. When pipes fail they are often blocked by sand and dirt particles that fell into the line. Blockages can result in sink holes which cause further problems including added repair costs.

Today, corrugated high-density polyethylene (HPDE) is largely utilized for storm drainage applications. This lightweight material is highly resistant to abrasion and corrosion and capable of supporting large loads due to its ability to absorb water stress. Corrugated HDPE is the preferred choice for low-head pipeline and gravity flow water management systems including: subsurface drainage, storm drainage, and storm water detention and retention systems. Note that storm drains are kept separate from sewer systems to prevent untreated sewage from being discharged into the environment.

HPDE has been used for over 20 years in the construction of highway and roadway storm drainage systems and drainage culverts. It has proven to be a durable, watertight material that withstands excessive water loads without cracking. One advantage HDPE offers is its ability to be manufactured with perforations. This makes for an ideal material when developing subdrainage systems to control subsurface water transport. Storm subdrainage systems are also a vital element for collecting landfill leachate that occurs when materials begin to compost. Perforated HDPE is used to collect and transport the collected leachate to another location where it can be safely discharged.

Corrugated polyethylene pipe has been instrumental in the engineering process of detention and retention storm water management systems. The rate of storm water runoff is regulated by municipalities. If water is accumulating faster than the permissible rate of discharge, excess water has to be directed to a storm water retention or detention system. The most common include subsurface piping and may also include, not limited to, above-ground retention ponds and bioswales.
