In part one of this two-part blog series, we went over some of the basics on erosion within stormwater systems, plus why it's a risk in these settings. Erosion can be a major damage risk on many construction or other job sites, and preventing it will help keep things both safe and healthy.

At Silver Leaf SWPPP, we're proud to provide a variety of stormwater pollution prevention services throughout Utah, from SWPPP inspections to services like erosion control and many others. In today's part two of our series, we'll go over a few more important points on erosion within stormwater systems, including how to spot the main signs of erosion and how our team will help prevent these concerns from taking place on any site.

Erosion and Sinkholes

One additional risk of stormwater erosion to be aware of: The possible forming of sinkholes, which takes place under the ground's surface when water flows underground, creating cavities in the soil. As the soil washes away, these cavities can become larger and larger, until eventually the surface collapses, creating a sinkhole.

This is another important reason why preventing erosion is so crucial: Not only can it lead to damage on site, but it can also create serious safety hazards for those living or working near potential sinkholes.

Primary Signs of Erosion Around a Stormwater System

Here are some of the telltale signs that erosion is taking place within or around a stormwater system:

  • Rills and gullies: In many cases, you'll be able to see visible evidence of disturbed soil and sedimentation, including shallow rills or gullies.
  • Water turbidity: If you notice opaque water due to high turbidity, or if you see suspended solids in the water table, this is a key sign of erosion.
  • Soil deposits: If you notice soil build-up on the sides of stormwater basins or other inlets, this could be an indication that sediment is passing through the system instead of being filtered for treatment.
  • Riprap washout: Movement or clustering of riprap or other previous erosion control attempts is a sign that those attempts were not successful, and further attention is needed.

Erosion Prevention Within Stormwater Systems

Here are some of the solutions we'll provide if you're dealing with erosion issues within your stormwater system:

  • Soil stabilization: One of the most crucial ways to prevent erosion within a stormwater system is through proper BMP installation and stabilization of soil. We'll work with you to ensure that the solution chosen will hold up in the local climate conditions, while also taking into account your budget considerations.
  • Buffer zone installation or repairs: Erosion control experts can properly install or repair a buffer zone to prevent further erosion from taking place. This will also improve the overall runoff flow within your stormwater system, allowing water to enter the collection basins and devices as it should.
  • Ground cover services: Our erosion control experts will use a variety of different ground cover methods to protect soil from erosion, including silt fences, straw wattles and more.
