This document provides guidance on infiltration facilities for stormwater management. It discusses infiltration trenches and basins, which rely on stormwater percolating through soils to remove pollutants. Key points covered include:
- Infiltration facilities can help treat urban runoff and reduce downstream pollutant loads.
- Soils suitable for treatment must contain sufficient organic matter and maintain aerobic conditions. Coarser soils are only suitable for quantity control.
- A feasibility analysis considers soil properties, depth to groundwater/bedrock, slopes, drainage areas, and proximity to structures. Pretreatment is required to control siltation.
- Pollutants are removed through various soil and biological processes as stormwater
The document provides guidance on designing biofiltration swales and vegetated filter strips to treat stormwater runoff. Biofiltration swales are vegetated channels that treat stormwater as it flows through. Vegetated filter strips treat stormwater as sheet flow as it travels across vegetation. Both use mechanisms like filtration, infiltration, adsorption and plant uptake to remove pollutants. Design criteria aim to maximize the residence time of stormwater in the systems to improve treatment. Specific criteria cover dimensions, slopes, vegetation and underlying soils. The design must ensure stormwater velocity and depth allow for effective pollutant removal during typical rain events.
Stormwater quality monitoring plays an important role in assessing the performance of stormwater management practices and the impacts of land use changes. Key aspects of designing a monitoring program include selecting sites, determining the monitoring period and frequency, selecting parameters, and using appropriate monitoring techniques. Automatic samplers can be programmed to collect samples based on time or flow volume and are useful for event-based monitoring. Proper design of a monitoring program ensures the data collected achieves the aim of the program cost-effectively.
