What is Re-charge?
Definition of Re-charge in Construction
To re-charge a site, is the technique of pumping water, or simply discharging water, into a location that has had its water table either depleted or dropped, to a level that is detrimental to the specific location.
In many large construction projects, the use of a de-watering system, to remove the water from the construction site, and in many cases, drop the water table, causes a negative reaction to adjacent properties. The stability of the surface of the land can be maintained, if the site is geologically stabilized by the water table. If the water table is artificially dropped, there are occurrences where the surfaces of the earth collapsed.
Water is a strong force and can maintain the integrity of the land due to its presence. Removing this water, can cause a lack of support, causing the surface to either fail or settle. The engineered re-charging of adjacent properties, is an important aspect to a de-watering program, and if neglected can cause severe harm to properties benefitting from the presence of a water table at a certain maintained elevation. De-watering together with re-charging should be an engineered system and the result of an improper de-watering plan can cause serious damage to neighboring properties.
