Design and Maintenance of Stormwater Infiltration Practices - School of Continuing Education, University Of Wisconsin

	Design and Maintenance of Stormwater Infiltration Practices

	Infiltration of stormwater has become an important topic in the management of urban runoff. Many communities now require infiltration of stormwater to help reduce pollutant discharges and recharge local groundwater systems. Under Wisconsin Administrative Code NR 151.12, a percent of stormwater runoff must be infiltrated on new development and redevelopment. Prior to infiltration, pretreatment is required for parking lot runoff and for runoff from new road construction in commercial, industrial and institutional areas. Discover the planning, design, construction and maintenance of complex infiltration systems. The following issues will be addressed: Why is infiltration of urban stormwater important to water quality?; Science of soils and infiltration; Site investigations; Pretreatment of stormwater runoff; Infiltration basins; Infiltration trenches and injection wells; Vegetation to use in infiltration systems; Monitoring and Maintenance
