Frequently Asked Questions

iSTORMWATER is a proud provider of stormwater management services for a variety of industries throughout the Washington, DC, region. Our team of stormwater management professionals understands the complex nature of properly reducing runoff in compliance with local and EPA regulations. Discover the answers to some of your most pressing questions in our FAQ section below!

What is stormwater management, and why is it important?

Stormwater management involves the effort to control and reduce the runoff of precipitation (rainwater or melted snow) into the ground, streets, lawns, and other sites and the improvement of water quality. Stormwater picks up contaminants, including pesticides, chemicals, and sediment, which pollute the water if not managed properly. Stormwater management is important to prevent physical damage from flooding and to maintain and improve ecological quality.

What is the difference between aboveground and belowground facilities?

When seeking to successfully manage the runoff near your building, you may wonder about the difference between our aboveground and belowground facility services. Aboveground systems are generally located where storm runoff can easily flow away from buildings, paved areas, and other public property into the system. In contrast, underground systems are designed around existing infrastructure, new development, and insufficient soil conditions.

Should I have both above- and belowground facilities for stormwater management?

Typically, you only need one or the other to remain compliant with EPA stormwater management guidelines. Underground facilities are generally better suited for newly developed areas and urban areas where space is a larger concern. Aboveground facilities are more commonly seen in rural areas where there are fewer concerns about water damaging other people’s property. Consult your iSTORMWATER representative to find out which solution is best for your industry or application.

What is a notice of violation, and how can iSTORMWATER help?

A notice of violation is a formal notice served to those who have not remained compliant with current stormwater management best practices. You can receive a notice of violation if you’ve violated any of the following conditions:

  • Illegal animal feedlot operations
  • Wastewater discharge without permits
  • Fish kills
  • Late or non-submittal of mandatory reporting
  • Illegal discharge of oil or hazardous materials
  • Late registration or renewal
  • Failure to employ a certified wastewater treatment plant operator
  • Improperly certified laboratory
  • Limits and monitoring violations of the National Pollutant Discharge Elimination System permit
  • And more

iSTORMWATER’s services help ensure you remain compliant with local and EPA guidelines pertaining to runoff management. Our aboveground and belowground facility services provide the solutions property owners need to avoid steep fines from stormwater regulation authorities.

Real Results

iStormwater LLC was an excellent choice. They made the process of the Storm water pond repairs seamless. They took charge of the project and got the project approved and passing the inspection. We highly recommend them and would use them again.

Lyonswood HOA

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.
