Wellpoint System

Definition

A Wellpoint System is a series of vertical pipes in the ground connected to a header and pump to drain marshy areas or control ground seepage.

Purpose

The purpose of a wellpoint system is to lower the groundwater level, facilitating construction, excavation, or remediation in areas with high water tables or poor drainage. It prevents water accumulation and stabilizes the soil.

Examples of Use

• Construction Sites: Draining groundwater to allow for excavation and foundation work.
• Dewatering: Controlling water levels in areas prone to flooding or waterlogging.
• Environmental Remediation: Managing groundwater levels during contamination cleanup.

Related Terms

• Dewatering: The process of removing water from soil or construction sites.
• Groundwater Control: Techniques used to manage the water table and groundwater flow.
• Sump Pump: A pump used to remove accumulated water from a sump basin or pit.

Notes

Wellpoint systems must be carefully designed and installed to effectively manage groundwater levels. They are critical in maintaining dry and stable conditions for construction and environmental projects.
