Project Description

Project

Water Main Upgrade

Location

Upper Darby, PA

Background

The client, a leading provider of water and wastewater utility services in Pennsylvania, is currently investing over $450 million to replace and improve their water and wastewater infrastructure. They called on EN Engineering to replace a large, existing cast iron water main with ductile iron.

Challenges

The replacement took place along a road with storm drain culvert crossings, which required detailed calculations and analysis. In addition, the road is heavily traveled and highly congested, which made field noting more difficult than usual.

Solutions

EN Engineering designed construction plans and coordinated environmental permitting for the project, which replaced the existing cast iron water main along the busy road. The replacement included approximately 7,650 feet of 8” ductile iron water main and took place along a road with two large storm drain culvert crossings, which required horizontal directional drill path calculations, analysis, and profiles. Because the road is a major transportation artery, field noting was particularly challenging.

The project was completed successfully, and the client relationship continues to expand. EN Engineering is now helping coordinate design and construction plans for future projects between the client and the local gas provider.
