Abstract: The Sunrise Highway Aqueduct was originally constructed in in 1908/1909 for the City of New York and included 83,500 feet of Lock-Bar steel pipe with riveted circumferential joints from Valley Stream, Long Island to the Nassau – Suffolk County line in Amityville at the time. The line was in regular service up until the 1950’s and had an extensive maintenance history, largely due to external pitting corrosion and internal lining failures. By the 1950’s (up to 1958), the line was only used in emergency supply mode for short periods due to high maintenance costs. It was used once in the 1966 drought and has been abandoned since. The objective of the study was to investigate and document the present condition of a strategically important 9.1 mile stretch of the pipeline, to assess its structural condition, and to determine the feasibility of re-purposing the pipeline into a force main to convey treated wastewater effluent from the Bay Park Sewage Treatment Plant to the Cedar Creek Water Pollution Control Plant. The assessment was completed in the fall of 2016 and the Spring/early summer of 2017, using a balance of multi-sensor platform deployments (CCTV, Sonar and LIDAR) and coupon and debris sampling to facilitate the feasibility assessment. The assessment concluded that the pipeline was suitable for rehabilitation using either CIPP or discrete pipe relining technologies. Due to the requirement to accommodate full vacuum loads in force main service, the liner was recommended to be designed as an AWWA M28 Class IV structural liner.
