Best Storm Water Management Practice: The Storm Infiltration Gallery

Natural drainage systems alone cannot meet the demands of storm runoff in communities today. It is mainly because of the large expanse of buildings, homes, multi-family housing, and paved surfaces.  Without proper stormwater management, heavy rains will cause havoc in cities and towns. It is critical to have a well-designed drain system for your property.

That said, rainwater runs off lawns and other lower areas without any available drainage outlet. In response to this drainage problem, many innovative ideas in the civil engineering world are in existence. One such innovative system is a storm infiltration gallery.

What Are Storm Infiltration Galleries?

Storm infiltration galleries are horizontal drains made from perforated pipes and upright plastic pipes that collect stormwater in low-lying areas. They are a relatively new development in urban planning. After collecting water in lower non-road areas, they dissipate it naturally to the ground or direct it to a sewer or storm drain network.

These galleries are innovative systems in the civil engineering world, complementing deficient old sewer or drain systems. As explained earlier, cities and housing developments generate more runoff today because of the impenetrable concrete structures. This water will pool on grass lawns or other lower open areas if there is no outlet. Storm infiltration galleries, therefore, complement the drain or sewer system.

How Does a Storm Infiltration Gallery Work?

They collect surface runoff in two ways:

1. Upright Plastic Pipes

The pipes are typically capped with simple grates to filter out solid debris to keep the system free of clogs. At the low point of the slop is where you will find these plastic pipes. The distance between the pipes and the number of tubes depends on the amount of surface runoff. Heavy surface runoff flows into the vertical lines, then to the lower horizontal pipes

2. Horizontal Cross Pipes

These form the secondary system and are located feet down from the upright pipes. Being perforated slightly, around 10% of their total surface area covered with gravel to filtrate solid debris and allow water to dissipate slowly. As the water gets into the horizontal pipes, it is then released slowly all through the perforations.https://www.facebook.com/swickandson

It naturally then seeps beyond the gravel and into the soil. This works perfectly when the amount of water is minimal. With large amounts of water, however, the system needs to direct water elsewhere. This is where a storm drainage system comes in.

Catchbasins may work well on asphalt and concrete surfaces. This may not be the case for heavy stormwater on lawns and other green areas. Sometimes, catch basins are insufficient in meeting the demands of the runoff in a community. As a result, it may pool around, which can be unsanitary. Stagnated water also harbors harmful pests and microbes, which can cause damage to structures foundations and is hazardous to the communities’ health.
