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]
Prior to SGMA, groundwater use was under-regulated to a point where many areas of the state faced major depletion, particularly in the San Joaquin Valley and other groundwater basins on the central coast and southern California that have been designated by the State's Department of Water Resources (DWR) as being critically overdrafted.
The law has led to the collection of more groundwater data and nearly $1 billion in state funding, and has raised public awareness about how heavy pumping, particularly for agriculture, has ...

Faced with the deepening scars of groundwater exhaustion, lawmakers passed SGMA — a sweeping road map to get the state to the point at which we’re taking out only as much water as comes in.
After state regulators determined in 2022 that the Kern groundwater plans were inadequate, the 14 so-called groundwater sustainability agencies in the area began splitting and forming new local ...
The Porter-Cologne Act (California Water Code, Section 7) was created in 1969 and is the law that governs water quality regulation in California. The legislation bears the names of legislators Carley V. Porter and Gordon Cologne. [1] It was established to be a program to protect water quality as well as beneficial uses of water.
California officials voted Tuesday to step in to monitor groundwater use in part of the crop-rich San Joaquin Valley in a first-of-its-kind move that comes a decade after local communities were ...
