Storm Drain Clearing

Storm Drain Problems During Heavy Rain

Storm drains are designed to move rainwater away from homes, buildings, and paved areas. When storm drains become blocked, water has nowhere to go and flooding can occur quickly. Regular storm drain clearing helps prevent property damage and drainage failures during heavy rain.

This guide explains why storm drains block, the risks involved, and how clearing is handled.

What storm drains do

Storm drains collect rainwater from roofs, driveways, yards, and streets. They direct water away from structures and into underground drainage systems or approved discharge areas.

When storm drains are clear, water flows away safely. When blocked, water pools and floods surrounding areas.

Common causes of blocked storm drains

Leaves and debris

Fallen leaves, twigs, and dirt are the most common causes of storm drain blockages.

Sediment buildup

Soil and sand can wash into drains and settle over time.

Trash and litter

Plastic, packaging, and debris can lodge in drain openings.

Tree roots

Roots can enter storm drain pipes through joints or cracks and restrict flow.

Collapsed or damaged pipes

Aging or damaged storm drain pipes can fail and block water movement.

Signs a storm drain is blocked

Standing water after rainfall

Water pooling near foundations

Overflowing drain grates

Slow draining during storms

Flooding in yards or driveways

Wet patches or sinking ground in the yard

These signs often worsen during heavy rain.

Risks of blocked storm drains

Blocked storm drains can cause serious damage if left unresolved.

How storm drain blockages are diagnosed

Proper diagnosis is essential. Guesswork often leads to repeat problems.

Visual Inspection

Drain openings and surface areas are checked for visible debris.

Drain Camera Inspection

Cameras identify blockages, roots, or pipe damage underground.

Flow testing

Water is introduced to confirm restrictions and drainage speed.

Storm drain clearing methods

Manual Debris Removal

Leaves, dirt, and trash are removed from drain openings.

Mechanical Clearing

Special tools break up compacted debris inside the pipe.

Hydro Jetting

High pressure water flushes sediment, roots, and buildup from pipes.

Pipe Repair or Replacement

Damaged sections are repaired if blockages are caused by pipe failure.

Storm drains should be inspected at least once a year and before heavy rain seasons. Properties with trees or heavy runoff may need more frequent maintenance.

Preventing storm drain blockages

Keep drain grates clear

Remove leaves regularly

Avoid dumping debris near drains

Maintain landscaping around drainage areas

Schedule routine inspections

Preventive care reduces flooding risk significantly.

Storm drains and basement flooding

Blocked storm drains can increase groundwater pressure around foundations, leading to basement flooding. Clearing storm drains often plays a key role in flood prevention.

When to call a professional

If water pools after rain or flooding occurs, professional storm drain clearing is recommended. DIY clearing often addresses only surface debris and misses deeper blockages.
