Disclosed are a system and method for controlling land deformation, and a method for optimal design of a well in a system for controlling a well in a system for controlling land deformation. The land deformation control system with respect to a land including an confined aquifer and an aquiclude above the confined aquifer includes a first well for water pumping from or water injecting into the confined aquifer; and one or more second wells spaced apart from the first well by a predetermined distance and having a lower end portion positioned in the aquiclude, wherein a water level of the second well is maintained at a preset water level value to control an amount of change in water head of the aquiclude, which drops due to pumping of the confined aquifer or rises due to injection with respect to each of the second wells.

Provided are methods and systems for draining underground soil moisture and water at a site. The methods and systems utilize a secured pipe system having a leading edge to drill the system into the earth, and perforations along portions of the surface of the system to receive accumulated water from underground and deliver it to the surface. A pipe cradle guide as provided is useful in the installation of the system. To also inject soil stabilizing materials (a mixture of sand and gel) into the earth using the secured pipe system, a removable canister is coupled to the distal end of the pipe system, and using water pressure the soil stabilizing materials are delivered to the soil by means of the secured pipe system.
