The Greenwood Metropolitan District (GMD) needed a durable, cost-effective solution for its $46 million wastewater treatment plant expansion and sewer replacement project. To improve performance and reduce long-term maintenance, GMD selected a large-diameter HDPE profile pipe system, known for its corrosion resistance and long service life.

HDPE Profile Pipe Chosen for Wilson and Coronaca Creek Sewer Replacement

This large-scale sewer replacement project required:

• 2,840 feet of 72-inch ID HDPE gravity sewer pipe
• 440 feet of 60-inch ID HDPE gravity sewer pipe
• 320 feet of 48-inch ID HDPE gravity sewer pipe
• Six PE manholes with 48-inch risers

All pipes were joined using integrated electrofusion bell-and-spigot technology, ensuring leak-free, long-lasting connections.

Why HDPE Profile Pipe Was the Best Choice

The decision to use spiral-wound HDPE profile pipe was based on several key advantages:

• Leak-Free Performance – Watertight joints prevent infiltration and exfiltration.
• Corrosion and Chemical Resistance – Unlike concrete or ductile iron, HDPE withstands harsh sewer environments
• Cost-Effective Installation – Lightweight materials reduce handling and installation costs
• Long Service Life – HDPE pipe is designed for 100+ years of performance
• Flexible & Earthquake-Resistant – Adaptable to shifting soils and environmental conditions

Jack Ravan, CEO, Water and Sewer Innovative Resources, praised the technology, stating:
“I can honestly say that this is a pipe system technology whose time is well past due.”
