Notice for the Community in the Vicinity of Jerome Ave and Gunhill
Vincent Sapienza Commissioner FOR IMMEDIATE RELEASE: December 19, 2018 CONTACT: [email protected], (845) 334-7868 No. 111 DEP TO WORK WITH U.S. GEOLOGICAL SURVEY TO STUDY SUSPECTED LEAK FROM THE CATSKILL AQUEDUCT Multi-year study will focus on pressure tunnel that carries water deep below the Rondout Valley Historic photos of the Rondout Pressure Tunnel can be found by clicking here The New York City Department of Environmental Protection (DEP) today announced that it will work with the U.S. Geological Survey (USGS) on a multi-year study to examine suspected leaks from a portion of the Catskill Aqueduct that runs several hundred feet below the Rondout Creek in Ulster County. DEP has been gathering information on this portion of the aqueduct, known as the Rondout Pressure Tunnel, for several years. In 2016, experts used a remote-operate vehicle to view the inside of the pressure tunnel for the first time since it was built more than a century ago. The vehicle used high-definition video cameras, acoustic equipment and other instruments to pinpoint several leaks in the tunnel. Scientific data collected by USGS will supplement the remote-operated vehicle’s inspection of the tunnel, giving DEP a clearer picture of where water is traveling after it escapes the aqueduct. At this time, DEP knows that a significant portion of the water comes to the surface and moves overland into the Rondout Creek in High Falls. USGS will begin its work by meeting individually with landowners in High Falls over the next several months. Scientists from USGS will seek permission to install monitoring instruments in existing groundwater wells, and potentially to install new monitoring wells in that portion of the valley. -

Little Known Facts and Trivia Sep 17Th -19Th IFMA Annual Conference and Expo New Orleans, LA • the Ancient Egyptians Kept Excellent Records of Nile River Floods
MECHANICAL CONTRACTORS 2st QTR 2014 – Apr - Jun The Delaware water supply system originates more than 120 miles north of New York City and comprises four reservoirs: Cannonsville, Neversink, Pepacton and Rondout. The 85‐mile long Delaware Aqueduct conveys drinking water from these reservoirs to the City’s distribution system, which originates at Hillview Reservoir in Yonkers. On average, the Delaware Aqueduct provides more than half of the approximately 1 billion gallons of clean drinking water required to meet the City’s demands every day. The aqueduct, the world’s longest continuous tunnel, was constructed between 1939 and 1944 and crosses Ulster, Orange, Dutchess, Putnam and Westchester counties. The aqueduct runs as deep as 1,500 feet below ground, varies in diameter from 13.5 to 19.5 feet, and was constructed by drilling and blasting. In most areas, the Delaware Aqueduct is lined only with reinforced concrete. However, two sections of the tunnel that run through limestone formations were lined with steel because limestone is more likely to cause wear and tear on the lining of the aqueduct. The ongoing investigation of the structural integrity of the aqueduct has found that small cracks formed where this steel lining ended. Circa 1941 – work in progress on the Delaware DEP has monitored the two portions of the aqueduct with leaks – one in the Orange County town of Newburgh, and the other in Aqueduct 3 years prior to its 1944 completion. the Ulster County town of Wawarsing – since the 1990s. The leaks release 15 to 35 million gallons of water a day, depending on the amount of water the aqueduct is carrying. -

Watershed Sub-Basin Identification Tools
Watershed Basin Identification Tools I. Purpose of project Introduction With 13 reservoirs and 3 controlled lakes in the 400-square-mile East-of-Hudson (EOH) New York City watershed, many watershed residents, understandably, are unfamiliar with the physical characteristics, water quality issues, and overlapping municipal boundaries of each reservoir basin or subwatershed. The reference material contained herein is intended to provide such information at a glance, to allow stakeholders to assess the water quality impacts of proposed development projects and zoning amendments in their districts, and to provide contact information for local and regional environmental groups that can offer guidance and assistance with citizen complaints and concerns about the management of their watershed. The EOH drinking water reservoirs and controlled lakes are fed by any combination of runoff from reservoir basin watersheds, aqueducts, streams and upstream reservoirs, and wastewater treatment plants (WWTPs). These same reservoirs are drained by a combination of calculated spills and releases, aqueduct discharges, and outside community withdrawals. The rate at which reservoir levels rise and drop fluctuates from year to year depending on local and regional precipitation levels. This means that reservoir surface area, volume, water intake and withdrawal also vary with fluctuations in annual rainfall. Land use characteristics within the 13 reservoir basins play an important role in the water quality of each reservoir: the greater the percentage of urban land use (impervious surfaces), the greater the volume of stormwater runoff and its associated impacts of nutrient and sediment loading. Therefore, water quality impacts also vary from year to year with corresponding fluctuations in rainfall and runoff. -
Rondout Creek and Adjacent Watersheds
SECTION 2 - R ONDOUT CREEK AND ADJACENT WATERSHEDS 2.1 The Rondout-Wallkill Watershed : The Rondout Creek is among the largest Map 2.1.1: Rondout – Wallkill Combined Watershed tidal tributaries to the Hudson River. The headwaters of the Rondout Creek begin in the Town of Shandaken at an elevation of 3,837 feet (DEP, 2008). The creek flows southwesterly through the Peekamoose area in the Town of Denning and into the Rondout Reservoir. The Creek is impounded by the Merriman Dam in the Town of Wawarsing to form the Rondout Reservoir, which stretches, into Sullivan County. The Rondout Creek picks up again below the dam with a State- mandated release of 10-15 million gallons per day from the reservoir, then travels southeast through Napanoch, where it bends northeast through the agricultural floodplains of Wawarsing, Rochester, and Marbletown where it plunges over the falls in High Falls. Beyond the hamlet of Rosendale, the Rondout Creek is joined by the Wallkill River beyond the Central Hudson-owned hydroelectric plant at Sturgeon Pool in Rifton. The Wallkill River system and Rondout Creek system form the approximately 3,082-km 2 (1,190 sq. mi.) Rondout-Wallkill watershed, the largest tributary basin entering the Hudson River south of the head of tide at Troy. The Rondout then continues to flow north over the Eddyville dam, where it is tidal for a 4-mile stretch until it empties into the Hudson River in downtown Kingston at an elevation of 190 feet. The Rondout enters the Hudson River Estuary at River Mile 91 (148 km), far enough north of the limit of saltwater intrusion so that the Rondout is characterized as a tidal freshwater system. -

Rondout West Branch Bypass Tunnel—TBM Boring in Hard Rock Against High Water Pressure and High Water Inflows Beneath the Hudson River in New York
Rondout West Branch Bypass Tunnel—TBM Boring in Hard Rock Against High Water Pressure and High Water Inflows Beneath the Hudson River in New York David Terbovic . The Robbins Company Martino Scialpi . The Robbins Company ABSTRACT A single shield hard rock tunnel boring machine is set to bore in hard rock, high water inflows and high water pressure in New York State. To overcome the difficult condi- tions the TBM is designed to handle 2500 gpm water inflows and seal against 30 bar of pressure. The TBM will bore a tunnel to replace a damaged portion of the Delaware Aqueduct that supplies half the raw water to New York City. The 2.5 mile bypass tun- nel passes beneath the Hudson River with geology consisting of shale and limestone. Due to the high water pressure and inflows the TBM was designed with new seal- ing systems for the main bearing and to close the TBM off if high water inflows are encountered. The TBM is to be equipped with two dewatering systems and multiple drilling and grouting systems for pre excavation grouting and segmental lining backfill. Systematic drilling and grouting procedures specific to the project were developed and incorporated into the TBM and backup design to ensure that the TBM can handle the extremely difficult ground conditions of the project. INTRODUCTION The construction of the 85 mile long Delaware Aqueduct commenced in 1939 and operations began in 1944. It conveys about 500 million gallons per day of water to the city of New York, about 50% of the city’s drinking water supply.
