Types of Catch Basin Clogs and How to Have Them Cleared Out

Not all catch basin clogs are created equal. The type of debris causing the blockage determines how difficult it is to remove and what equipment is needed.

Sediment and Sand Buildup

The most common type of clog. Sand, silt, and fine sediment wash into catch basins from roads and parking lots. This material settles to the bottom and gradually reduces drainage capacity. Regular vacuum truck cleaning handles this easily.

Leaf and Organic Matter

Properties near mature trees experience heavy leaf fall that clogs both the grate surface and the basin interior. Decomposing organic matter also creates foul odours and attracts pests.

Oil and Grease Deposits

Vehicle oils and grease float on the water surface and, over time, solidify into a thick layer that restricts flow. This type of clog is common in parking lots and auto shops. Hydrovac jetting is often needed to break up hardened oil deposits.

Construction Debris

Gravel, concrete fragments, and construction waste can fill a catch basin quickly. These heavy materials compact over time and require powerful vacuum extraction.

Root Intrusion

Tree roots can infiltrate catch basin walls and connecting pipes through cracks and joints. Camera inspection can identify root intrusion before it causes a complete failure.

How We Clear Them

Our approach depends on the clog type. Standard vacuum service handles sediment, leaves, and trash. Hydrovac jetting is deployed for oil deposits and compacted material. For root intrusion or structural issues, we recommend camera inspection followed by targeted repair.
