The forensic science of ‘Bio-Film’ in NYC high-rise roof tanks
Roof tanks are a fixture of the NYC skyline, but what happens inside them is a matter of Forensic Biology. While the water entering the tank is sterile, the “Open-Atmosphere” nature of many tanks allows for the development of a Bio-Film. At Inside NYC Water, we break down the forensic science of NYC water tank […]
Why ‘Staten Island’ has the city’s most frequent water main breaks per mile
Staten Island is a borough of hills, sprawl, and unfortunately, Water Main Breaks. Per mile of pipe, Staten Island statistically experiences more “Breaks” than Manhattan or the Bronx. This isn’t due to poor management; it is a result of Geological Diversity and “Historical-Infill” challenges. At Inside NYC Water, we broke down the forensic reasons for […]
The ‘Hydraulic Signature’ of NYC Parks: Seasonal irrigation demand
New York City’s parks, from the sprawling lawns of Prospect Park to the manicured beds of Bryant Park, are massive Seasonal Consumers of water. For a hydraulic engineer, a park is a “Variable-Load” on the local distribution grid. At Inside NYC Water, we perform a forensic audit of NYC park irrigation hydraulics. The “Irrigation-Pulse” Timing […]
Why ‘Battery Park City’ has its own independent water recycling system
Battery Park City (BPC) in Lower Manhattan is a global leader in sustainable urban living. One of its most advanced features is the Independent Water Recycling systems found in many of its “Green” skyscrapers, like the Solaire. At Inside NYC Water, we break down the engineering of Battery Park City’s water recycling. The “Blackwater-to-Service” Loop […]
The forensic science of ‘Cavitation’ in high-velocity city pumps
Inside the massive pumping stations that move NYC water, a “Silent-Killer” known as Cavitation is a constant threat. Cavitation occurs when high-velocity water creates “Vacuum-Bubbles” that implode against the pump’s impeller. At Inside NYC Water, we explore the forensic science of pump cavitation. The “Implosion-Peak” Failure When these bubbles implode, they generate Micro-Jets of water […]
How ‘Climate Change’ is impacting the salinity of the Delaware Aqueduct source
As sea levels rise, the “Salt-Front” of the Hudson River is moving further north. This is a critical issue for the Delaware Aqueduct, which pulls water from reservoirs that are connected to the Hudson via underground geological features. At Inside NYC Water, we investigate the impact of climate change on NYC water salinity. The “Salt-Front” […]
The impact of ‘Electric Vehicle’ charging stations on local underground utility heat
The transition to electric vehicles (EVs) is a win for the air, but a new challenge for the underground. The high-voltage cables required for Level-3 Charging Stations generate significant heat. At Inside NYC Water, we analyze the impact of EV charging heat on nearby water mains. The “Thermal-Radiance” Zone EV cables can reach temperatures of […]
The technical reality of ‘Lead-Service-Line’ replacement in older neighborhoods
NYC has a clear plan to replace its Lead Service Lines, but the technical reality is complex. In neighborhoods like Bedford-Stuyvesant or Ridgewood, the proximity of other utilities makes this a “Precision-Excavation” task. At Inside NYC Water, we break down the engineering of NYC lead-line replacement. The “Slit-Trench” and “Gun-Boring” Tech To avoid digging up […]
Why the ‘Meatpacking District’ has unique heavy-duty distribution mains
The Meatpacking District in Manhattan, once home to massive slaughterhouses and refrigerations plants, has a “Heavy-Duty” distribution grid that is unique in the city. These mains were designed to handle the “High-Volume-Scouring” required for large-scale meat processing. At Inside NYC Water, we break down the forensic engineering of the Meatpacking grid. The “Double-Walled” Main Logic […]
The future of NYC Water: ‘City Tunnel No. 3’ and the 100-year security plan
New York City’s most important construction project isn’t a skyscraper; it is City Tunnel No. 3. Underway since 1970, this 60-mile tunnel is the “Key” to the city’s 100-year security plan. At Inside NYC Water, we break down the engineering of City Tunnel No. 3 and what it means for your future. The “Shaft-and-Valve” Redundancy […]
