With increased stormwater run-off through a park and the increasing development occurring near the Allentown, Pa., airport, the Hanover Township Public Works Department knew infrastructure changes were necessary.

Hanover Public Works Director Vince Milite had some concerns about his department tackling a major stormwater management project with its limited staff. Milite contacted Oldcastle Precast-Mid-Atlantic to get ideas to remedy the situation. By partnering, the township and Oldcastle came to a solution that relies on reinforced concrete pipes (RCP). The project was completed in late fall, 2016.

Milite and Oldcastle Precast designed the system, incorporating 48 feet of 48-inch, Class 3, RCP (three 16-foot spans, side-by-side); six, 48-inch flared end sections (one on each end of a row); three bell end sections (for downstream); and three spigot ends (for upstream). The assembly formed the new stormwater structure.

The company provided engineering design support and manufactured the 48-inch reinforced concrete pipe at their Croydon, Pa., facility and the 48-inch flared end sections at their Folsom, N.J., facility.

“The precast drainage solution worked very well. Before, the water backed up on the upper fields, where they had smaller drainage pipes. By using the triple cell 48-inch line and flared end sections, the run-off flows out of the upper area into the lower region of the community park,” Ed Pentecost, sales manager at Oldcastle Precast, says. “Moreover, compared to casting in place, digging a hole and placing RCP makes the project much easier, quicker and more efficient.”

“The project turned out great for our group,” Milite says. “We are all very happy with the entire process and outcome.”
