How a Ranney Method® Well Works
|
|
A Ranney® Collector Well or Radial Horizontal Collector Well operates hydraulically, similar
to a vertical well. The lateral well screens are installed near the bottom of the formation, so
more of the saturated thickness of the aquifer can be used. Since these well screens are horizontally
positioned, much longer screen lengths can be installed, reducing the velocity of the water entering
the screen slots and maximizing well efficiency.
This reduced velocity also minimizes head losses and slows the rate of plugging, extending the
intervals between scheduled maintenance. The well pumps are installed in the central caisson,
allowing usage of larger and more energy-efficient pumps and motors. This further reduces O & M
requirements and costs.
