Two new water mains were placed under Eastchester Bay to ensure a reliable supply of water for those in the area. The new pipelines replace an older 12-inch subaqueous water main and a temporary 16-inch main previously installed on the City Island Bridge. “Tunnelling under Eastchester Bay was a complicated project that will ensure a reliable water supply for City Island for decades to come,” said DDC Commissioner Thomas Foley. “I commend the DDC staff for their diligence in working through the pandemic and for their dedication to environmental protection and ensuring that the work did not disturb environmentally sensitive areas nearby.” During construction, engineers utilized horizontal directional drilling technology to create two 2000-foot pathways under the bay for pipes to travel from Rodman’s Neck peninsula on the mainland toward City Island. The process included boring a pilot hole from one surface point to another; expanding that hole to the appropriate diameter to accommodate pipes being installed; grouting a steel sleeve in place to stabilize the created tunnel; then pulling water main pipes through the enlarged hole. Work on City Island also included construction of a receiving pit where new pipes tied into the local water main distribution system. The project received a diamond award in the water resources category from the American Council of Engineering Companies of New York. It was also named “2021 Project of the Year” in the $25-100 million category by the Construction Management Association of America’s New York/New Jersey Chapter for providing safe and reliable drinking water to 4500 residents on City Island. “Thanks to the team’s strategic and creative work, the residents and small businesses of City Island will have reliable access to the clean drinking water they deserve,” said New York City Mayor Eric Adams. Workers drilled into the ground on City Island to create a passage for new pipes beneath Eastchester Bay. WTR
