How to Increase Water Yield from a Well?

Optimizing Well Depth and Pump Selection

When drilling a well, the ideal depth depends on the geology and hydrology of the area, but a minimum depth of 100-150 feet is recommended for a reliable water supply. A pump with a suitable horsepower rating is essential to handle the static lift of the water, which should be calculated based on the depth and water table elevation. A general rule of thumb is to use a pump with a horsepower rating of 1-2 HP for every 100 feet of static lift.

Regular Well Maintenance and Cleaning

Regular well cleaning is crucial to maintain water yield and prevent contamination. This involves pumping out sediment and debris from the well, which can be done by pumping the well at least once a year, depending on the water usage. A well screen size of 4-6 inches is recommended for most residential wells, but the optimal screen size may vary depending on the well’s construction and water characteristics.

Permitting and Submersible Pump Installation

Before drilling a well, it’s essential to obtain the necessary permits and approvals from local authorities. When it comes to pump selection, a submersible pump is often a good choice for wells with high static lift or long discharge pipes. A submersible pump can be installed directly in the well, reducing the risk of contamination and increasing the water yield. However, the cost of a submersible pump can be higher than a jet pump, with prices ranging from $500 to $2,000 or more, depending on the pump’s horsepower rating and features.

A hand-dug well, on the other hand, can be a more cost-effective option, but it requires careful construction and maintenance to prevent contamination and ensure a reliable water supply. The cost of a hand-dug well can range from $3,000 to $10,000 or more, depending on the well’s depth and construction.
