How can you improve water availability from a low-yield well? An underground reservoir stores water as the well slowly produces it, and a separate cistern pump supplies the home on demand. It doesn’t increase the well’s output, but it can provide a larger reserve than a small indoor tank. This installation walkthrough features a 2,500-gallon underground concrete cistern and explains how the well, storage tank, and home supply are connected.
Underground reservoir installation for a low-yield well
When an underground reservoir may help
A low-yield well may produce water more slowly than a household needs at peak times. Storing the well’s output in a larger reservoir can create a supply buffer for household use. Depending on the site and system design, the tank may also provide a place to receive hauled water.
How the system works
- The well fills the underground reservoir over time.
- A pump saver can shut down the well pump if it detects that the well is drawing air, giving the well time to recover.
- A float switch coordinates pump operation with the water level in the tank.
- A separate cistern pump supplies water to the home through the pressure system.
The exact equipment, wiring, plumbing layout, tank size, and pump requirements depend on the well and property. The video shows one installation example, not a one-size-fits-all design.
Plan the installation carefully
Underground tank installation involves excavation, existing utility lines, plumbing, and electrical work. Have the site and system designed for your property, locate underground utilities before digging, and use qualified well, pump, electrical, and excavation professionals as appropriate. Local permits and requirements can also affect the design.
Pumps larger than 1.5 horsepower may require additional design considerations. Have a qualified professional review the system before selecting or connecting equipment.
