HDPE pipe is the most durable and resilient piping for water and water supply line applications. The Water-Line™ product suite includes Base-Line™ for mining operations, Crystal-Line™ for potable and sewer water infrastructure,  Hard-Line™ for high-pressure, high-corrosive and heavy wall applications and Sewer-Line™ for sewage applications.

HDPE is ideal for water infrastructure applications, as it will never rust, leak, or corrode and it is virtually maintenance-free. Light weight and flexibility provide for easy installation.

United Poly Systems can customize the pipe's diameter, thickness, color, and other options to suit your project.
