What Is Preventive Stormwater Maintenance?

In the context of stormwater management systems, preventive maintenance means having a service provider such as iStormwater come through and inspect, repair, tune, and assess your existing stormwater management systems. This might mean basic maintenance and a confirmation that everything looks as it should; it may mean identifying major problems or potential violations so that you can resolve them with additional facilities or major changes; or it can mean a test run for inspection by an insurance company or government body.

How long will preventive maintenance take?

This depends on a lot of different factors, so it’s hard to give a single answer. The size of your property, the complexity of your stormwater management systems, and general accessibility to relevant areas of your property will all determine how long it takes our team to complete a maintenance servicing.

What will preventive maintenance cost me?

Much like the previous question, this is a question with no fixed answer. Analyzing a single rudimentary pumping system to prevent flooding in a hotel basement in a low-risk area is a very different task from analyzing a combination of systems used to keep a large shopping center situated in a high-risk flood area dry.

Can I perform maintenance myself?

Some aspects of maintaining certain stormwater management systems may be DIY-able, but in many cases, this simply exposes you to additional liability without offering the improvements or insight you’ll see with proper preventive maintenance services. If there are aspects of your system that should be maintained between professional sessions, our team can help you identify these and explain them to you.

Preventative Stormwater Maintenance Services

Stormwater management systems are designed to control runoff, improve water quality, reduce flooding, and help properties meet local stormwater requirements. However, these systems require ongoing maintenance to continue performing as intended.

At iSTORMWATER, we provide preventative stormwater maintenance services that help commercial property owners, property managers, HOAs, developers, and government agencies protect their stormwater assets, maintain compliance, and avoid costly repairs.

From stormwater ponds and bioretention facilities to sand filters and underground detention systems, our maintenance programs are designed to identify and address issues before they impact system performance.

What Is Preventative Stormwater Maintenance?

Preventative stormwater maintenance is the routine servicing, cleaning, repair, and upkeep of stormwater management facilities before small issues become major problems.

While inspections help identify deficiencies, preventative maintenance focuses on correcting those deficiencies and keeping stormwater systems functioning properly year-round.

A comprehensive maintenance program may include:

Sediment and debris removal
Vegetation management
Erosion repair
Inlet and outlet structure maintenance
Stormwater pond maintenance
Bioretention facility maintenance
Sand filter maintenance
Proprietary treatment device maintenance
Underground stormwater system cleaning
Corrective repairs
Maintenance documentation and reporting

Rather than waiting for flooding, compliance concerns, or system failures to occur, preventative maintenance helps property owners proactively manage their stormwater infrastructure and extend the useful life of their systems.

Why Preventative Maintenance Matters

Stormwater facilities are constantly exposed to sediment, debris, vegetation growth, erosion, weather events, and everyday wear.

Without routine maintenance, systems can gradually lose capacity and effectiveness. Sediment accumulates, vegetation becomes overgrown, structures deteriorate, and treatment practices may no longer perform as designed.

Over time, neglected maintenance can lead to:

Reduced stormwater treatment performance
Increased flooding and drainage issues
Erosion and structural damage
Costly repairs and rehabilitation projects
Regulatory violations and Notices of Violation (NOVs)
Shortened infrastructure lifespan

A proactive maintenance strategy helps property owners address issues early, reduce long-term costs, and protect their investment in stormwater infrastructure.

Stormwater Systems We Maintain

Stormwater Ponds

Retention ponds and detention ponds require ongoing maintenance to manage sediment accumulation, vegetation growth, erosion, and structural integrity.

Bioretention Facilities and Rain Gardens

Bioretention facilities rely on healthy vegetation, properly functioning filter media, and unobstructed flow paths.

Sand Filters

Sand filters can become clogged over time as sediment accumulates within the system.

Underground Stormwater Systems

Underground detention systems, vaults, and piping networks often require specialized cleaning and maintenance services.

Proprietary Stormwater Treatment Devices

We maintain a variety of manufactured treatment devices, including hydrodynamic separators, cartridge filtration systems, and other proprietary BMPs.

Common Preventative Maintenance Services

Sediment and Debris Removal

Regular removal helps maintain treatment efficiency and system capacity.

Vegetation Management

We remove invasive species, manage overgrowth, and help maintain healthy plant communities within stormwater facilities.

Erosion Repair

Early repairs help protect facility integrity and prevent sediment from entering downstream systems.

Structure Cleaning and Maintenance

Catch basins, inlets, outlets, risers, forebays, and control structures require routine cleaning and maintenance.

Vacuuming and Jetting Services

Vacuuming and jetting help remove sediment, debris, and blockages that may restrict flow.

Corrective Repairs

Timely corrective maintenance helps prevent larger structural issues and more expensive rehabilitation projects.

Benefits of a Scheduled Maintenance Program

Improved compliance
Reduced emergency repairs
Extended asset life
Better budget planning
Enhanced property appearance

Maintenance Service Agreements (MSAs)

Many stormwater facilities require routine maintenance throughout the year to remain compliant and perform effectively. Rather than scheduling services as issues arise, many property owners and managers choose to establish a Maintenance Service Agreement (MSA).

An MSA provides a proactive approach to stormwater management by establishing a customized maintenance schedule based on the specific needs of your property and stormwater facilities.

Benefits of a stormwater maintenance agreement may include:

Scheduled inspections and maintenance visits
Routine sediment and debris removal
Vegetation management
Priority response for maintenance needs
Maintenance documentation and reporting
Budget predictability
Reduced risk of compliance issues
Long-term asset protection

Whether managing a single commercial property or a portfolio of sites, a customized maintenance program can help simplify stormwater management while reducing the likelihood of unexpected repairs and regulatory concerns.

Real Results

iStormwater LLC was an excellent choice. They made the process of the Stormwater 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 stormwater regulations over time.

Kelly E.

So helpful with all of my water issues.

Kel R.

Great communication and leadership and a family friendly atmosphere. Thank you John!
