Storm drains play an important role in moving stormwater away from streets, parking lots, and buildings during heavy rainfall. When these systems function properly, they protect properties from flooding and erosion. When problems develop, it is essential to know who is responsible for maintaining the drainage components on or near your property.
In Texas, storm drain responsibility depends on the location of the system, the type of property served, and whether the drainage structure falls within a public or private boundary. Understanding how these systems are divided helps property owners plan maintenance and prevent water-related issues throughout the year.

How Storm Drain Systems Are Structured
Stormwater systems include several connected components that move water from paved surfaces into larger drainage networks. A typical system includes:
- Catch basins and curb inlets: Collect stormwater from paved areas.
- Storm drain pipes: Carry water underground toward larger channels.
- Manholes and junction boxes: Allow access for cleaning and inspection.
- Detention or retention features: Slow or store excess runoff.
- Outfalls: Release water into designated drainage channels.
Ownership and maintenance responsibilities depend on how these components connect to public rights-of-way or private property.
Public vs. Private Storm Drain Systems in Texas
Public Storm Drain Systems
Public storm drains are maintained by cities or counties. These systems typically include:
- Street inlets and grates along public roads
- Storm mains located in public easements
- City-maintained culverts, ditches, and outfall structures
Public works departments clean and repair these components as part of routine municipal drainage management. Their responsibility generally ends at the boundary where private property begins.
Private Storm Drain Systems
Private stormwater systems serve individual properties or developments. Common examples include:
- Parking lot drains at commercial or industrial properties
- Internal drainage networks for apartment communities
- Stormwater structures managed by HOAs
- On-site detention features located on business or residential land
Property owners or management groups are responsible for maintaining these systems, including cleaning, inspection, and structural repairs.
If a drainage issue occurs within a private system, the owner must address the problem to prevent flooding or damage on their property.
Why Proper Storm Drain Maintenance Matters
Consistent maintenance prevents many problems associated with heavy rainfall and runoff. Well-maintained storm drains help:
- Reduce the risk of standing water or overflow
- Protect pavement, foundations, and landscaped areas
- Improve drainage performance during peak storms
- Extend the lifespan of underground storm lines
- Support compliance with local drainage guidelines
When debris, sediment, or structural issues restrict flow, water is more likely to accumulate at the surface, increasing the potential for property damage.
Responsibilities Based on System Ownership
The party responsible for maintenance depends on where the storm drain is located and how it connects to the larger system.
City or County Responsibilities
Municipalities generally handle:
- Cleaning and inspecting storm inlets located in public roadways
- Maintaining storm mains under public rights-of-way
- Clearing debris from city-maintained ditches or culverts
- Addressing issues related to municipal storm infrastructure
Cities typically schedule routine cleanings and respond to drainage concerns involving public systems.
Private Property Owner Responsibilities
Owners of commercial, industrial, or residential land maintain drainage features located within their property boundaries. This may include:
- Cleaning catch basins and inlet grates on-site
- Removing sediment or debris within private storm lines
- Ensuring proper grading for runoff flow
- Maintaining or repairing private drainpipes
- Managing on-site detention or retention areas
Routine maintenance helps prevent blockages that could lead to flooding on the property.
HOA and Property Management Responsibilities
Shared residential or commercial developments often use internal drainage networks. HOAs or management groups coordinate:
- Inspection and cleaning of shared storm drains
- Regular hydro-jetting and debris removal
- Maintenance of common-area drainage structures
- Coordination with local drainage departments when needed
These efforts ensure water moves effectively from private systems into public networks.
What Happens When Storm Drains Are Not Maintained
Neglected storm drains can experience issues that increase repair costs and disrupt property operations.
Flooding and Surface Water Accumulation
Debris buildup or collapsed sections of pipe restrict flow, causing water to collect in parking lots, entrances, or low-lying areas.
Erosion and Pavement Damage
Overflow may wash soil away from foundations or pavement edges, leading to cracked asphalt or unstable surfaces.
Structural Deterioration Inside the System
Sediment, organic matter, and standing water can corrode or weaken storm drain components over time.
Increased Maintenance Needs
Smaller problems become more complex when left unaddressed, turning simple cleanings into larger structural repairs.
Routine maintenance helps prevent these issues and extends the life of storm drain systems throughout the property.
How TX Hydrojet Supports Storm Drain Maintenance
TX Hydrojet provides inspection, cleaning, repair, and emergency support for storm drains and manholes across Texas. Their licensed team assists property owners by ensuring drainage systems function correctly during changing weather conditions.
Inspection and Assessment
Technicians use camera inspection tools to assess underground lines and identify issues such as debris buildup, cracks, or intrusion. These inspections offer clear insight into system condition without excavation.
Hydro-Jetting and Cleaning
Industrial-grade hydro-jetting removes sediment, leaves, grease, and other debris from storm drain lines. This restores flow capacity and reduces the likelihood of blockages during heavy rain.
Repair and Rehabilitation
If storm lines show signs of deterioration, TX Hydrojet provides:
- Crack and joint sealing
- Replacement of damaged covers and frames
- Repair of collapsed or corroded sections
- Structural restoration for manhole components
Repairs are completed to local drainage standards and designed to support long-term durability.
Preventive Maintenance Programs
Recurring maintenance services help property owners stay ahead of changing weather conditions. Scheduled cleaning and inspection reduce the likelihood of emergency flooding during peak storms.
24/7 Emergency Response
Storm drain failures and unexpected backups can occur without warning. TX Hydrojet offers 24/7 emergency response with rapid arrival, helping properties manage rising water and restore system functionality efficiently.
How Often Should Storm Drains Be Serviced?
Most properties benefit from inspection and cleaning once or twice per year. Additional maintenance may be recommended for locations with heavy tree cover, frequent storms, nearby construction, or rapid debris accumulation.
Seasonal service before major weather periods further reduces the risk of overflow.
The Role of Public and Private Cooperation
Public storm systems and private property drainage networks work together to move water safely away from buildings and roadways. When each part of the system is maintained correctly, runoff flows efficiently from private areas into municipal systems.
Routine attention from property owners helps support overall drainage performance throughout the community.
Final Thoughts
Storm drain maintenance responsibility in Texas depends on system location and ownership. Public entities manage storm drains located in roadways and municipal easements, while private property owners maintain drainage features within their boundaries. HOAs and management groups oversee shared systems within residential or commercial communities.
Proactive maintenance helps prevent flooding, supports proper system performance, and keeps drainage structures operating as intended. TX Hydrojet provides inspection, cleaning, repair, and emergency support to help ensure storm drain systems remain reliable throughout the year.
