Quick Answer
Residential wells are typically drilled to a shallower depth, ranging from 50 to 200 feet, and are used for household purposes. Agricultural wells, on the other hand, are often drilled to greater depths, usually between 200 to 500 feet or more, to access aquifers with higher water yields. The selection of pumps and well casings also differs significantly between residential and agricultural wells.
Residential Well Characteristics
Residential wells are typically drilled to access local water tables, which may not be as deep as those found in agricultural areas. In most cases, a residential well can be drilled to a depth of around 100 to 150 feet, allowing for easy access and relatively low drilling costs. When it comes to pump selection, residential wells often require smaller pumps that can handle lower flow rates, usually between 5 to 20 gallons per minute (gpm). It is also essential to consider the well’s location, nearby water sources, and local regulations when drilling a residential well.
Agricultural Well Considerations
Agricultural wells, however, require a more significant investment, often involving deeper drilling depths to reach more extensive aquifers. Drilling depths can range from 300 to 500 feet or more, depending on the local geology and the desired water yield. Agricultural wells typically require more substantial pumps that can handle higher flow rates, usually between 20 to 100 gpm or more. Additionally, agricultural wells often necessitate the installation of larger well casings, which can be more expensive to purchase and install.
