Benefits of Underground Stormwater Detention

Stormwater is termed as that water which falls to the ground when there is rain or even snow. More stormwater runoff tends to be caused by increased construction of acres of hard, impervious surfaces including concrete and even asphalt. In this case such stormwater runoff causes flooding, pollution and even soil erosion. Such impact mitigation calls for development to include designated drainage systems that helps catch, store and release the stormwater runoff. When one is faced with challenges of space and terrain constraints the best option is to build a drainage system that stores stormwater underground. Underground detention is in most cases highly considered due to the fact that it saves apace as well as providing a way to construct new development in steep or rather restricted areas while at the end meeting environmental regulation. Stormwater management typically requires strategic and site specific engineering to ensure that the rainwater run a million directions across the ground plus releasing it in the same manner. Below are some of the key advantages of underground stormwater detention.

It maximizes the economic potential of a given space. Underground detention systems tend to be buried deep under the roads meaning that it helps eliminate the need to purchase more land. Rather than having to buy a larger parcel for a pond, there is that option of installing the stormwater detention system underneath the parking lot which helps maximize on the economic potential of a given space.

It prioritizes flow control. These systems are installed in compliance with the various regulations to help store stormwater for many years while releasing the water at controlled intervals to help prevent flooding. In this case the pre-development flow rate ted to be based on specific engineering calculations meaning that the stormwater will therefore flow into surface waters with that same frequency as well as volumes that it did right before construction. Therefore underground stormwater detention provides a precise way to control flow while as well meeting the regulations requiring restoration and maintenance of pre-development conditions.

It’s highly advantageous especially when the land tend to be expensive or even steep terrain. Underground detention is ideal for dense urban areas whereby a small development footprint tend to be important due to the expense as well as limited availability of the required real estate. In addition it helps capture and store stormwater while at the end releasing it in a controlled manner that mimics natural runoff conditions. This at the end helps in saving new land purchase due to making use of the available one.

Underground detention systems provide treatments by placing an open-bottoms vault on a layer of sand allowing water to infiltrate while being filtered at the end. This is beneficial in the sense that it helps improve water quality discharge while even reducing the required volume storage. Having such stringent rules for water quality in the stormwater detention helps protect the environment while promoting overall health safety. Given that the runoff water is stored underground and the released through an outlet pipe in a controlled manner it means that the water is properly treated to enhance good water quality while complying with the environmental regulations.
