The City of Glendale and the Maricopa County Flood Control District needed a drainage pipe for a municipal storm sewer project on Northern Avenue in Glendale, Arizona.
The majority of the new storm sewer would be installed beneath a very busy roadway, with installation depths approaching 22-ft. There were also existing utilities to take into account, including a gas line running parallel to the new storm sewer. The tight working conditions, construction challenges and importance of traffic control demanded a unique storm drain solution that could fill all of these needs.
DuroMaxx Steel Reinforced Polyethylene (SRPE) pipe and reinforced concrete pipe (RCP) were both considered for the project. DuroMaxx was chosen because it was lighter weight, allowing for the use of smaller handling equipment for the pipe and accommodating for the smaller site footprint. Also, the smaller outside diameter of DuroMaxx allowed for more narrow trench widths, resulting in reduced installation costs and also provided for more clearance for the nearby gas line and additional utilities.
Sundt Construction installed 10,900-ft. of 60-in. and 72-in. diameter DuroMaxx pipe.
“DuroMaxx provided an impressive production rate,” said Javier Aviles with Sundt Construction. “It was able to handle the deep burial with acceptable deflection and it also fit more easily between the tight existing utilities than pipes with larger outside diameters.”
