Soakage Trenches are linear excavations backfilled with sand and gravel injecting stormwater runoff into the ground recharging groundwater. There are various components within the system - inlet piping, aggregate storage basin and perforated piping. The trench surface may be covered with grating, stone, sand, or a grassed cover with a surface inlet and may also be installed under hard surfaces such as driveways. All facility components, vegetation, and source controls shall be inspected for proper operations and structural stability. These inspections shall occur, at a minimum, quarterly for the first two years from the date of installation, then two times per year afterwards, or within 48 hours after each major storm. Training and/or Written Guidance information for operating and maintaining Soakage Trenches shall be provided to all property owners and tenants. A copy of the 0 & M Plan shall be provided to all property owners and tenants. Inspection Logs shall be kept by the facility owner demonstrating the following items have been inspected and are being maintained properly: • Access to the Soakage Trench shall be safe and efficient. Obstacles preventing maintenance personnel and/or equipment access to the components of the facility shall be removed. • Algae Growth located on top of the soakage trench should be removed and disposed of properly. • Debris/Sediment that is found to clog the pipe shall be removed and disposed of in accordance with applicable federal and state requirements. • Failing Soakage Trenches shall be repaired and/or replaced if water is noticed on top of trench within 48 hours of a major storm. • Piping shall be cleared of sediment and debris to maintain conveyance. If piping is clear of sediment and debris and yet conveyance is poorly maintained, fabric around the pipe shall need replacing. • Shut -Off Valve or Flow -Blocking Mechanism may have been required with the construction of the drywell to temporarily prevent stormwater from flowing into it, in the event of an accidental toxic material spill. This may also involve mats kept on- site that can be used to cover inlet drains in parking lots. The shut-off valve shall remain in good working order, or if mats or other flow -blocking mechanisms are used, they shall be kept in stock on-site. • Sediment in the aggregate obstructing storage and infiltration shall be excavated and replaced. • Vegetation such as trees should not be located in or around the soakage trench because roots from trees can penetrate the unit body, and leaves from deciduous Stormwater Management Manual 4-33 Eugene 2014 trees and shrubs can increase the risk of clogging the intake pipe. Large shrubs or trees that are likely to interfere with operation will be identified at each inspection and removed. Spill Prevention Measures shall be exercised on site when handling substances that contaminate stormwater. Releases of pollutants shall be corrected as soon as identified. Non -Chemical Pest Control measures shall be taken to prevent development of insects, mosquitoes, and rodents.
