School’s Storm Water Problem Solved With HDPE Retention System

The 234,000-gal, two-unit storm water detention system at LaGrange High School in LaGrange, Calif., was a job of complexities and potential challenges. For example, due to the site’s limited area, the system required a network of pipe and connections at odd angles to fit the crowded space. There also were time constraints to consider. But thanks to the prep work performed by the manufacturer of the corrugated high-density polyethylene (HDPE) pipe, McCoy Grading Inc. easily assembled it. The pipe was selected because of its ability to meet blueprint specifications and its history of good performance.

Corrugated HDPE pipe has the highest strength-to-weight ratio available among drainage products and provides durability, performance and favorable cost efficiencies, according to the Plastics Pipe Institute Inc. (PPI). The product used at LaGrange has a brand name called NFLOW and an effective pH range from 2 to 14. According to the PPI, no other type of pipe would have allowed the design of the system to be drawn and constructed for these close confines or have provided the speed of assembly.
