Stormwater Maintenance

Ongoing maintenance is critical to the performance of every stormwater system. Without regular maintenance, the system will eventually fail due to buildup and structural issues, and routine upkeep can prevent costly rehabilitative and restorative repairs.

AQUALIS offers comprehensive maintenance and regular servicing solutions to ensure your stormwater systems operate correctly, extend the life of your investment, and avoid costly NOVs.

Quantity + Quality

Maintenance is typically the responsibility of the property owner, and whether the property has an aboveground or underground stormwater system, the objectives remain the same: ensuring the system meets requirements for water quantity (the volume of water stored in and leaving the site) and water quality (the chemical, biological, and physical composition).

Types of Stormwater Maintenance

Aboveground SCM Maintenance

Aboveground SCMs (BMPs) can vary depending on the needs of the site, and each requires a different type of stormwater maintenance. With a proper understanding of the system on the site, a proactive maintenance plan for any aboveground system will include:

  • Inspection of all structures
  • Removal of trash and debris
  • Sediment control
  • Structural maintenance (stabilizing poor coverage and erosion)
  • Vegetation management (mowing grass, removing nuisance or invasive growth, managing beneficial species)

Underground SCM Maintenance

Underground SCMs are engineered to convey rainwater away from impervious surfaces of the site through a storm sewer system, which will require regular maintenance to ensure proper function. Common underground SCM maintenance plans include:

  • Inspection of sumps and structures
  • Sediment volume assessment
  • Removal of sediment, trash, and debris
  • Vacuuming (Vactor) and high-pressure jetting
  • Filter cartridge replacement
  • Documentation for any structural deficiencies or sinkholes

In honor of National Pollinator Week, it seemed fitting to share our latest pollinator install in Chicago, Illinois. This install is especially fascinating as it is a rooftop garden and is double in size of our typical garden installs. With the assistance on AQUALIS Environmental Interns, this project took on a life of its own […]
