Stormwater Management Ponds in MD, VA & DC

Stormwater runoff is a significant source of water pollution in urban areas. Plus, runoff occurs in greater amounts where concrete and asphalt cover large areas of the ground. Stormwater ponds help mitigate both problems, serving as a treatment basin for contaminant removal and a collection basin for reduced flooding.

Neglected stormwater ponds are prone to discharging pollutants downstream, increasing the risk of flooding, threatening the stability of downstream channels, and causing an aesthetic nuisance. On the other hand, proper maintenance ensures the safety, effectiveness, and longevity of a stormwater pond.

Routine Preventive Maintenance

  • Inspections: Stormwater pond inspections should be performed as part of an overall stormwater management plan. They should be conducted quarterly and within 24 hours of every storm event that generates more than 1 inch of rain. Inspectors should come with a detailed checklist of things to look for after rainfall, including obstructions, trash accumulation, erosion, and sedimentation.
  • Vegetation management: Regular mowing helps prevent erosion and maintains good aesthetics around the stormwater pond. Fertilizer and pesticide use should be minimized to avoid downstream pollution.
  • Debris and litter removal: Trash is a common cause of obstructions at the inlet, outlet, and orifice. To prevent this, general trash pickup should occur during every inspection and maintenance visit.
  • Mechanical equipment maintenance: Check valves, pumps, fence gates, locks, and mechanical components during periodic inspections.
  • Structural component check: Inspect the outlet, inlet, orifice, trash rack, and trickle channel for signs of wear and tear.

Non-Routine Corrective Maintenance

  • Bank stabilization: Vegetated areas must sustain adequate ground cover to ensure proper runoff infiltration and effective contaminant filtering. If plants die, the area must be replanted and stabilized immediately.
  • Sediment removal: Approximately once every six months, accumulated sediment must be removed from the bottom of the outlet structure. During this process, pond depths should also be checked at several points. If accumulated sediment has decreased the pond’s original design depth by more than 25%, it should be removed.
  • Structural repair and replacement: Eventually, the structural components of a stormwater pond will need to be repaired or replaced. Do this when necessary to keep the pond in good operating condition.

Benefits of Stormwater Pond Maintenance

Maintenance will always be needed for stormwater ponds. Failure to keep up with requirements could create a false sense of security regarding the ability of a pond to store stormwater runoff and remove pollutants effectively. The benefits of keeping up with preventive and corrective stormwater pond maintenance include:

  • Maintain good water quality downstream
  • Decrease the risk of flooding
  • Ensure the stability of downstream channels
  • Prevent unpleasant odors, algae blooms, and nuisance insects
  • Sustain an attractive, well-kept area

"Incredible stormwater management service. The owner John consulted on a property I manage and ended up saving us thousands of dollars in environmental fees from the government. Now, our property is compliant with the EPA and we have a great partner to keep us maintained on storm water regulations over time."
