Stormwater Management: What You Need To Do

Worker checking the bolts of a blue water pipelineStormwater management plays an important role in environment responsibility for both commercial and residential properties. This practice manages surface runoff, otherwise known as water from snowmelt or rain.

Stormwater runoff is one of the primary culprits behind the largest pollution problems and is also a risk to public safety. Without proper management systems, the polluted water ends up in the nearest creak, lake, river, or ocean, causing massive pollution concerns. The outcome can also compromise your construction project.

For Stormwater Facilities, a full service underground contractor, a good management system is essential to preventing water flow from compromising the nearest body of water.

Stormwater management is only effective if you include a site evaluation and consider the construction activities involved along with the design of the stormwater control system. To design an effective system, you need to know the peak flow, runoff volume, storage volume, hydraulic performance, and other relevant stormwater calculations.

Here is a quick look at stormwater management:

Evaluate the Site, Develop Accordingly

The construction site will determine the ease or difficulty of your stormwater management plan. For example, areas that experience intense rainfall will need more control measures. The activities involved will also tell you if your site needs engineered controls or not.

So you need to collect site information, from soil texture and susceptibility to erosion to location of surface waters and receiving water (e.g., lakes, creeks, wetlands, etc.).

Ensure an Efficient Filtration System

Your hydraulics system determines the flow of water through your stormwater filtration system. You need to do a thorough evaluation, which involves checking the scour velocity in tanks and pipes, maintaining high-energy flows outside the filter bed, and checking the hydraulic grade line (HGL).

In evaluating the velocities, you immediately figure out where sediments deposit. Meanwhile, maintenance of high-energy flows ensures that your filtration system functions still, even during heavy rainfall bringing in sediments, garbage, and organic matter. As for the HGL, it allows you to check if the system can handle peak water flow. The HGL has to make room for design flows in the drainage system—without leading to flooding at one point.

Stormwater management is critical to maintaining the environment and ensuring a successful construction project. Make sure your site is well prepared through site evaluation and development and an efficient system.
