Well Conditions in San Marcos
In San Marcos, wells typically reach depths of 100-300 feet to access the fractured crystalline rock aquifer. The local geology consists of fractured granite bedrock with decomposed granite overlay, which affects drilling methods and well performance.
Common issues we see in San Marcos: low yield wells due to fractured rock, seasonal water table fluctuation. With 12-18 inches annually rainfall, proper well maintenance is essential for reliable water supply.
Homes in San Marcos often benefit from properly sized pressure tanks to handle the 100-300 feet well depths common in this area. We recommend tanks that accommodate the specific flow rates typical of fractured crystalline rock aquifer wells.
