SUPPLEMENTARY NOTES This study was conducted in cooperation with the U.S. Department of Transportation, Federal Highway Administration. 16. ABSTRACT This report describes an approach for estimating infiltration rates for dry wells that are constructed using standard configurations developed by the Washington State Department of Transportation. The approach was developed recognizing that the performance of these dry wells depends upon a combination of subsurface geology, groundwater conditions, and dry well geometry. The report focuses on dry wells located in unconsolidated geologic materials.

  • Single Family Residential Stormwater Management Plan Dry Well (Infiltration) Construction Inspections
    Single Family Residential Stormwater Management Plan DRY WELL (INFILTRATION) Definition : A dry well is an excavated pit filled with gravel and sand that provides temporary storage of runoff from roofs and allows for infiltration of that runoff over a 48 hour period. Constraints : • Dry wells should not be used in areas where their operation may create a risk for basement flooding, interfere with septic sewage disposal systems, or cause downslope seepage problems • May not be installed on slopes greater than 20% • Drainage area to each dry well shall not exceed 1000 square feet • Dry wells may not be used in HSG D or if the infiltration rate of the soil is less than 0.27 inches per hour • Dry wells are intended to capture rooftop runoff only Design Guidance: • Dry wells must be installed in accordance with the attached detail • Dry wells should not intercept water table, bedrock, fragipan or other confining layer • Dry wells must be located down gradient of building structures and set back at least 10 feet from buildings, 50 feet from water supply wells and 25 feet from septic systems • Dry wells must be set back at least 50 feet from fill slopes of 25% or steeper • Soils will be evaluated during excavation by ASCD representative to evaluate soil suitability assumed in original design which may alter type of practice to be constructed Installation: • Minimize compaction of dry well bottom and sidewalls • Collection pipes from downspouts shall be 4”-6” PVC installed at min. slope of 1% • The bottom of the dry well excavation should be

  • City of Elk Grove Dry Well Project Guidance and Lessons
    City of Elk Grove Dry Well Project Guidance and Lessons Learned Document 2/28/2017 CITY OF ELK GROVE DRY WELL PROJECT Guidance Document Guidance and Lesson Learned from the Elk Grove Dry Well Project The Elk Grove Dry Well Project (project) was a four-year study to investigate the risk of groundwater contamination associated with the use of infiltrating stormwater through dry wells. The project involved a large field component that included the installation of two dry wells with pretreatment and a network of groundwater monitoring wells. The project has two study sites located in Elk Grove, California. The first site was the City of Elk Grove’s Corporation Yard, a 0.6-acre parking facility that is a bus fleet servicing area and maintenance yard, and the second site was the Strawberry Detention Basin, a water quality basin that collects stormwater from a 168-acre residential neighborhood. As part of the project study, stormwater and groundwater samples were collected for two years and analyzed for over 200 contaminants. Estimates of infiltration rates were also made. A companion modeling study of the fate and transport of contaminants through the vadose zone was performed. Scientific and government reports evaluating the risk to groundwater quality associated with dry well use were reviewed and compiled in a literature review (annotated bibliography). Lastly, information from other states with developed dry well programs, often known as underground injection control systems, was summarized in fact sheets with the goal of understanding the regulations, permitting, siting, and design guidelines used elsewhere. This guidance document summarizes some of the key lessons learned from this work.
