Wellpoint

Definition

A Wellpoint is a perforated pipe surrounded by sand to permit the pumping of groundwater.

Purpose

The purpose of a wellpoint is to provide a means for efficiently removing groundwater from an area, allowing for dewatering and stabilization of the soil for construction and other projects.

Examples of Use

• Dewatering Systems: Using wellpoints to lower groundwater levels at construction sites.
• Groundwater Management: Controlling seepage and water levels in excavation areas.
• Remediation Projects: Facilitating the removal of contaminated groundwater.

Related Terms

• Perforated Pipe: A pipe with holes or slots to allow water to enter.
• Sand Filter: A layer of sand surrounding a wellpoint to prevent soil from clogging the pipe.
• Header Pipe: A main pipe that collects water from multiple wellpoints and directs it to a pump.

Notes

Wellpoints are integral to wellpoint systems and must be properly installed to ensure efficient groundwater removal. Regular maintenance is necessary to keep the system functioning effectively.
