Storm drains play an important role in protecting commercial properties from flooding, erosion, and standing water. When these systems work as designed, they move stormwater efficiently away from paved areas and buildings. When they become blocked or neglected, even moderate rainfall can lead to surface pooling and drainage issues that affect day-to-day operations.
Routine cleaning is essential for keeping storm drains reliable throughout the year. Knowing how often to schedule maintenance helps property owners stay ahead of weather changes and reduce the likelihood of unexpected backups during peak storms.
This blog will tell you everything you need to know, and when to call in a Houston plumber to help maintain your commercial storm drain systems.
Understanding Commercial Storm Drain Systems
Storm drains on commercial properties work as part of a connected system that directs water away from high-traffic areas. These systems commonly include:
- Catch basins: Grated inlets that collect runoff from parking lots, loading areas, and walkways.
- Storm drain piping: Underground lines that transport water to outfalls or larger networks.
- Manholes: Access points for professional inspection and cleaning.
- Detention or retention features: Structures designed to temporarily hold or slow runoff during heavy rain.
Over time, leaves, sediment, and debris collect inside these components. If cleaning is delayed, the buildup can restrict flow and increase the likelihood of surface flooding during storms.
Why Routine Cleaning Matters for Commercial Properties
Commercial sites often handle more runoff than residential areas because they contain larger paved sections and experience heavier traffic. Routine cleaning supports long-term drainage performance by helping:
1. Prevent Surface Flooding
Clogged drains reduce flow capacity. Even partial blockages may cause water to pool around entrances, walkways, or parking areas during heavy rainfall.
2. Protect Pavement and Structures
Standing water can erode soil, weaken pavement edges, and increase moisture near building foundations. Preventive cleaning helps reduce these risks.
3. Maintain Safe Conditions
Clear drains reduce slip hazards by preventing water from lingering in high-traffic zones. They also help limit moisture accumulation in underground areas.
4. Avoid Emergency Service Needs
Routine maintenance reduces the likelihood of sudden backups that may require urgent repairs. Keeping drains clean year-round supports predictable system performance.
How Often Should Commercial Storm Drains Be Cleaned?
Most commercial storm drain systems benefit from professional inspection and cleaning once or twice per year. However, the ideal schedule varies based on several conditions.
1. Property Type and Usage
Different sites accumulate debris at different rates:
- Retail centers and office complexes often require cleaning every 6–12 months.
- Industrial sites may need more frequent cleaning due to sediment or byproduct runoff.
- Apartment complexes and community developments benefit from semi-annual service before major rainfall periods.
2. Surrounding Environment
Properties with significant tree cover or landscaped areas collect more leaves and organic matter. This material quickly builds up inside catch basins after storms, increasing the need for more frequent cleaning.
3. Local Weather Patterns
Texas regions experience varying storm intensity. Locations with frequent downpours or seasonal flash flooding benefit from cleaning before and after major storm periods to ensure flow capacity remains consistent.
4. Age and Condition of the System
Older underground piping may be more susceptible to buildup or deterioration. These systems often require more frequent inspection to ensure water can move properly through storm channels.
5. Visible Drainage Concerns
Pooling water, slow flow, or odors near storm drains indicate the need for immediate inspection and cleaning, regardless of the scheduled maintenance cycle.
Warning Signs That Storm Drains Need Cleaning
Common symptoms that suggest a storm drain requires service include:
- Standing water after light or moderate rainfall
- Slow drainage around catch basins
- Debris collecting around inlet grates
- Odors coming from storm basins
- Soil erosion near drain structures
- Water backing up toward walkways or parking areas
These signals often appear before larger backups occur. Scheduling an inspection early helps prevent more extensive problems.
What Professional Storm Drain Cleaning Includes
Storm drain cleaning involves more than removing debris from a grate. TX Hydrojet uses specialized tools and techniques to restore flow throughout the drainage system.
1. Camera Inspection
Video inspection tools allow technicians to evaluate the condition of underground lines. This process identifies cracks, blockages, or structural issues without excavation.
2. Hydro-Jetting and Line Flushing
High-pressure hydro-jetting loosens and removes accumulated debris, sediment, and organic matter. This method restores pipe diameter and supports full drainage capacity.
3. Buildup and Debris Removal
Flushed material is removed from the system to prevent re-accumulation. Proper debris management ensures drains remain clear after service.
4. System Flow Verification
After cleaning, technicians assess water movement through the system to confirm proper drainage.
5. Maintenance Scheduling
A customized maintenance plan helps property owners stay ahead of seasonal changes, reducing the likelihood of unexpected drainage concerns.
Risks of Delaying Storm Drain Cleaning
Neglecting storm drain maintenance can lead to issues that require more extensive repair work. Common risks include:
- Water pooling in parking areas or building entrances
- Erosion around paved surfaces
- Deterioration of underground storm pipes
- Disruption to property operations during heavy rain
- Increased strain on older drainage components
Routine cleaning helps avoid these concerns and reduces long-term maintenance costs.

Planning inspections during these periods helps maintain drainage reliability throughout the year.
Long-Term Benefits of Routine Storm Drain Cleaning
Regular cleaning and inspection provide several key advantages:
1. Reduced Repair Costs
Keeping drains clear helps prevent major blockages that may require structural repairs or pipe replacement.
2. Extended System Lifespan
Clean storm pipes experience less corrosion and flow restriction, supporting long-term performance.
3. Improved Property Conditions
Consistent drainage maintenance helps keep paved areas dry and supports stable walking and driving surfaces.
4. Predictable System Performance
Routine service allows drainage networks to function consistently during heavy storms.
Final Thoughts
Commercial storm drains should generally be cleaned once or twice per year, with additional service for properties that collect significant debris or experience frequent rainfall. Routine cleaning supports proper water flow, helps prevent flooding, and reduces long-term maintenance needs. TX Hydrojet provides inspection, cleaning, repair, and emergency service to help commercial properties keep their storm drain systems functioning effectively throughout the year.
