Infiltration Trenches. Infiltration trenches are essentially leaky pipes in a stone-filled trench. Surface runoff or downspouts can be directed to infiltration trenches, where the stormwater drains out of a perforated pipe into the trench/gravel and then into the soil. For larger storms that produce more runoff, some stormwater will be stored in the stone trench, but water can also flow through the pipe to a larger BMP. Maintenance: • Do not drive vehicles over an infiltration trench as it can cause compaction or crush the perforated pipes. • If the trench has an access pipe, it should be checked and cleaned out regularly.
