| Short Description |
In Chapter 173-160-111 (21) WAC (Washington Administrative Code) it defines a dewatering well as a "cased or lined excavation or boring that is intended to withdraw or divert ground water for the purpose of facilitating construction, stabilizing a land slide, or protecting an aquifer." Currently, the most common use of a dewatering well is for dewatering a shallow aquifer to facilitate construction of underground utilities, a road, or a building foundation. The most common casing is Schedule 40 PVC casing. The average depth is about 20-feet. And the most common installation method is jetting. Hundreds of these wells are constructed and decommissioned in Washington every year. | |
