Well Metering & Groundwater Extraction Reporting Program Overview
Program Summary
On March 18, 2025, the SABGSA Board adopted Ordinance 25-001 requiring well owners within the San Antonio Creek Valley Groundwater Basin to install a flow meter with a visual, volume-recording totalizer on their wells, submit documentation of compliance by April 1, 2026, and report monthly groundwater extraction readings to the SABGSA on a twice-a-year basis, through a form provided by the SABGSA. De minimis extractors – defined as those who extract two acre-feet or less per year solely for domestic purposes – are exempt from metering and reporting requirements. Ordinance 25-001 also outlines a pathway to exemption for inactive and abandoned wells provided all of the SABGSA’s criteria are met.
Compliance Summary and Key Deadlines
Below is a summary of definitions, requirements, and key deadlines for SABGSA’s Metering & Groundwater Extraction Reporting Program. There is also a page dedicated to each well type to provide clarity.

Program Goals
Program Objective: Facilitate consistent and reliable reporting of groundwater extraction volumes excluding de minimis wells (under 2AFY).
Program Purpose: Provide accurate and reliable data of groundwater extraction volumes as specified in GSP as a Tier 1 Management Action. Informs future SABGSA demand management actions.
Program Goal: Sustainably manage, protect, and maintain the groundwater resources within the Basin consistent with SGMA for the benefit of all water users.
