  2. Infiltration/Inflow - Wikipedia

    en.wikipedia.org/wiki/Infiltration/Inflow

    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 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.

  7. Leaky Acres Recharge Facility - Wikipedia

    en.wikipedia.org/wiki/Leaky_Acres_Recharge_Facility

    The effectiveness of the groundwater recharge through the soil was studied from 1971 to 1980. Over that period, the average recharge rate was 10,848 acre feet per year at 86 percent facility efficiency. The 10-year mean actual recharge rate based on actual water delivered, total ponded area, and total days of recharge was 4.7 inches per day.

  8. Rain garden - Wikipedia

    en.wikipedia.org/wiki/Rain_garden

    When an area's soils are not permeable enough to allow water to drain and filter at an appropriate rate, the soil should be replaced and an underdrain installed. Sometimes a drywell with a series of gravel layers near the lowest spot in the rain garden will help facilitate percolation and avoid clogging at the sedimentation basin. [ 13 ]

  9. Groundwater recharge - Wikipedia

    Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer .
