Bronx River Floatables Control Facilities


Bronx, New York<br style='line-height:2px'>New York City Department of Environmental Protection

HAKS, in joint venture, provided construction management services for the $26 million floatables control facilities project on the Bronx River for the New York City Department of Environmental Protection as part of an on-call contract for miscellaneous construction projects in the downstate New York area.

The Bronx River Floatable Control Facilities project installed four below-ground floatable control measures in three existing combined sewer overflow (CSO) outfalls to the Bronx River in the southern Bronx. The floatable control facilities for Outfalls HP-004 and HP-007 are being located in the West Farms section of the Bronx. The facility for Outfall HP-009 is being located in the borough’s Soundview section.

The four sites are: Bronx Park Avenue (regulator CSO-27A), Bronx Zoo (regulator CSO-27), Soundview Park (regulator CSO-13, outfall HP-009), and West Farms Road (regulators CSO-28 and CSO-28A, outfall HP-004). Construction included installation of netting facilities on the West Farms Road and Soundview Park outfalls, which will capture floatables debris carried by storm overflows from regulators CSO-28, CSO-28A and CSO-13. Weir lengths of regulators CSO-27 and CSO-27A were expanded to allow installation of underflow mechanical screens. Regulator CSO-13 was also expanded and minor cosmetic repairs made to the HP-009 headwall in Soundview Park.

Work at Soundview Park included relocation of a telemetry box, headwall repairs, regulator expansion excavations and dewatering system installation. Work at West Farms Road included test pit and dewatering system installations, excavations, and installation of precast culvert pipes. Work at the Bronx Zoo included regulator expansion excavations, dewatering system installation and cutting and removal of the existing sewer roof.
