Excavation is an effective stormwater pollution prevention strategy as it allows for stormwater to be diverted away from vulnerable areas. Digging trenches, digging ditches, and installing storm drain inlets are all methods of excavation. Excavating storm drains can help protect the environment by preventing stormwater runoff, which carries pollutants like sediment, petroleum products, fertilizers, and pesticides into storm drains. These pollutants can then be carried to nearby creeks, rivers, or the ocean.
Digging trenches is one of the most common excavation methods that help maintain invaluable ecosystems across the world today. Trenches allow stormwater runoff to flow through and eliminate any build-up of contaminants that could potentially cause stormwater pollution.
Trench excavation helps to prevent stormwater pollution in different ways:
- Trenches help manage stormwater by allowing the storm wastewater to be filtered through the soil, sand, gravel, or other filtration systems.
- Trenches also help prevent stormwater erosion, which can lead to sediment, chemicals, and bacteria entering into water bodies that are not designated for recreational swimming or other drinking water sources.
The primary pollutants coming from stormwater runoff include trash, debris, oil & grease, pesticides/herbicides/fertilizers, petroleum products, sediment, and bacteria.
- Excavation projects in stormwater management can prevent stormwater pollution by allowing storm wastewater to be filtered through the soil or a filtration system where pollutants are broken down into simple elements that plants and soils can absorb easily.
- Excavation projects can also help prevent flooding by acting as a temporary reservoir for stormwater that would otherwise cause low-lying areas to flood during heavy rainfall events or when the snow melts quickly.
Installing Storm Drain Inlets
Stormwater pollution is a significant problem that affects storm drain systems. Storm drains remove stormwater runoff by transporting it into lakes, rivers, and oceans without treatment; however, this can lead to contaminated waters due to the pollutants found in stormwater.
There are two main types of storm-caused contaminants: sedimentation and nonpoint source pollution (NPS).
- Sedimentation is the most common storm-related contaminant and occurs when stormwater runoff carries sediment into water bodies.
- Nonpoint source pollution (NSP) is caused by pollutants such as oil or chemicals that make their way from land to storm drains through several ways; for example, when rain washes animal waste into storm drains or industrial chemicals run off into storm sewers.
Excavation can help prevent stormwater pollution by installing storm drain inlets (also known as curb cuts) on sidewalks, streets, and driveways that allow stormwater to enter the ground instead of traveling directly into lakes, rivers, and oceans without treatment.
The role of excavation in stormwater pollution prevention has become an increasingly important part of the construction process. Not only does it help to protect our natural resources, but it also helps companies avoid fines.
