Why Storm Drain Maintenance Matters in the Pacific Northwest

Where Stormwater Meets Strategy

The Pacific Northwest is known for its vibrant green landscapes, healthy forests, and abundant waterways—thanks in large part to the region’s frequent rainfall. While this rain sustains the natural beauty we enjoy, it also creates an ongoing challenge: managing stormwater. That’s where storm drains come in. Catch basins—commonly referred to as storm drains—are essential for capturing rainwater runoff and trapping debris and sediment before the water flows into local waterways. These systems help channel excess water from streets, rooftops, and sidewalks, reducing the risk of flooding and water damage. However, without routine maintenance, storm drains can become clogged, leading to backups that impact both local infrastructure and the surrounding environment.

What Happens When Storm Drains are Neglected?

Clogged storm drains can quickly become a serious problem, especially during heavy rains. When water can’t flow properly, it can result in:

Street and neighborhood flooding
Increased pollution in local rivers and streams
Damage to public infrastructure like roads and culverts
Safety Hazard to customers, clients, and loved ones
Higher risk of erosion and landslides, particularly in hilly areas

Even small blockages—like a pile of autumn leaves—can have a significant impact if left unaddressed

Environmental Impacts

Stormwater that flows through storm drains often ends up in nearby rivers, lakes, or sounds and oceans—without being filtered or treated. As it moves across streets, parking lots, and other surfaces, it can pick up pollutants such as motor oil, lawn fertilizers, heavy metals, and trash. If storm drains are not properly maintained, these substances are more likely to enter waterways—affecting water quality and local infrastructure.

Regular storm drain cleaning plays a key role in:

Preserve wildlife habitats
Reducing pollutant loads in downstream water bodies
Minimizing sediment buildup in drainage systems and waterways
Preventing blockages that can lead to overflows and localized flooding
Supporting compliance with local and state water quality regulations

By keeping storm drains clear and functioning properly, we help protect public health, avoid costly repairs, and support the responsible management of our region’s water resources.

You Make a Difference

While cities and counties are responsible for maintaining public stormwater systems, individual property owners, and maintenance companies also play an important role in reducing stormwater issues. Small, consistent actions can help prevent localized flooding and keep stormwater systems functioning effectively.

Practical steps include:

Regular professional cleanings to remove built-up sediment, debris, and pollutants from catch basins and underground piping
Clearing leaves, trash, and yard debris from storm drains near your home—particularly during the fall and after heavy rain
Properly disposing of chemicals like oil, paint, or pesticides—never pouring them into gutters or storm drains
Reporting damaged or blocked drains to your local public works or stormwater utility department

When combined across communities, these efforts help extend the life of stormwater infrastructure, reduce maintenance costs, and protect water quality throughout the region.
