Infiltration will occur where local groundwater elevation is higher than the sewer pipe. Gravel bedding materials in sewer pipe trenches act as a French drain. Groundwater flows parallel to the sewer until it reaches the area of damaged pipe. In areas of low groundwater, sewage may exfiltrate into groundwater from a leaking sewer. [6]
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
[1] [2] A percolation trench is similar to a dry well , which is typically an excavated hole filled with gravel. [ 3 ] Another similar drainage structure is a French drain , which directs water away from a building foundation , but is usually not designed to protect water quality.
A French drain, PVC pipe, or other drainage system is installed in the newly made channel. The installed drain is covered with new cement. The installed drain is covered with new cement. The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the ...
Flood control dams were constructed along the creek in 1978 within the Ned Brown Forest Preserve near Elk Grove Village, Illinois, creating the 590-acre (2.4 km 2) Busse Lake. A diversion tunnel was constructed approximately 1.6 miles (2.6 km) north of the confluence with the Des Plaines River, at a point where the two streams are separated by ...
The area has been covered in >24 inches of soil, but areas outside the Johns-Manville property have problems with asbestos contamination, including other beachfront areas near the Waukegan and Zion. [5] The site will be redeveloped as a soccer and baseball complex. [6] 12/30/1982: 09/08/1983: 12/31/1991: N/A: N/A ILD980500102: Yeoman Creek ...
Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
In 1994, analysts estimated that in the U.S. total cleanup costs of groundwater totaled between $500 billion and $1 trillion. [18] Until about 2000, the majority of groundwater remediation was done using "conventional technologies" (e.g., pump-and-treat systems), which have proven costly to meet applicable cleanup standards.
