Over 9 miles to be Inspected; Night Work to Minimize Impact
Nassau County Executive Edward P. Mangano and Department of Public Works (DPW) Commissioner Shila Shah-Gavnoudias today announced the inspection and assessment of the Sunrise Highway (Rte. 27) Aqueduct will continue on Sunday, April 16, 2017. A study has been underway to determine if an existing, non-utilized underground pipeline can be used to connect the South Shore Water Reclamation Facility in Bay Park to Cedar Creek’s ocean outfall pipe. Thus far, 7,500 feet have been inspected and this path toward success remains achievable.
“This project will determine an ability to utilize an existing pipeline under Sunrise Highway as a force main to transport treated wastewater effluent from the South Shore Water Reclamation Facility in Bay Park to the Cedar Creek ocean outfall pipe. If proven useable, the reutilization of this pipeline will save taxpayers hundreds of millions of dollars while also improving water quality in Reynolds Channel, Hewlett Bay, Brosewere Bay, and the Rockaways.”
Inspection will be performed along 9.5 miles of Route 27 in the Villages of Lynbrook, Rockville Centre, and Freeport; and Wantagh, Bellmore, Merrick, and Baldwin in the Township of Hempstead in Nassau County. During the inspection and assessment, two lanes of eastbound traffic will be affected. To minimize the impact on motorists, pedestrians, residents and businesses, the majority of the work will be performed in stages on shorter sections of NY Route 27 during off-peak, nighttime hours between 10:00 p.m. and 6:00 a.m. Night construction is scheduled for Sunday through Thursday in the eastbound direction, starting in Lynbrook and proceeding east to Wantagh. At least one travel lane will remain open at all times.
Motorists should consider alternate routes such as Merrick Road to avoid slow traffic, especially during the start of daily night construction around 10:00 p.m. Drivers who cannot use alternate routes are reminded to drive carefully through the work zone for their safety as well as the safety of the highway work crew. As with most projects within roadways, this inspection and assessment work may be rescheduled due to inclement weather.
The project is being performed by AECOM, USA, Inc. under contract with Nassau County DPW and is scheduled to be completed in early summer 2017. This project is intended to aid the County in its decision making regarding suitability for utilization of an existing aqueduct as a force main to transport treated wastewater effluent from Bay Park Sewage Treatment Plant to the Cedar Creek Water Pollution Control Plant. The reutilization of this pipeline will become part of the County’s clean water initiative to reduce nitrogen in the Western Bays. The main purpose of such a diversion serves to improve the water quality of the surrounding bays and protect our shoreline. Existing assets (such as the aqueduct), some of which have sat unused or underutilized for years, will be repurposed and put back into service.
Field investigation of the aqueduct includes, but is not limited to: providing a topographical survey of the manholes along the aqueduct with top of casting and bottom of pipe elevations at a minimum; providing a visual survey of the exterior and interior of the aqueduct; documenting all visible damage and structural deficiencies with photo and video records; documenting the condition of the steel, rivets, joints, connections, valve chambers and manholes at a minimum; and, performing any other testing or inspections that will aid in the determination of the friction factor of the pipeline and its capacity for pressurization. Inspection findings and conclusions will be summarized in a technical report and allow the County to determine the next steps.
Nassau County achieved similar success in 2012, when the Mangano administration kept its commitment to cleanup Zach’s Bay near Jones Beach by connecting a State-owned wastewater treatment facility to Cedar Creek.
