Are you considering building a water treatment plant in New York City? Read on to learn about the cost and size of filtration plants in New York City. We’ll also discuss what goes on at a filtration plant and its required work. After reading this article, you’ll be better equipped to decide whether or not to build a plant. You’ll also better understand how many workers are needed to operate a filtration plant in New York City.
Cost of building a water treatment plant in New York City
The city has been in the process of rebuilding its water treatment plant. Its original construction contract was for $1.3 billion, and by September 2009, the project cost had soared to $3.2 billion. Comptroller Bill Thompson has said that the project was “over budget and overdue.” Many reasons were cited for the high costs, including poor upfront design, changes made during the construction, and slow execution at the management level.
The current project is expected to cost $2.8 billion. It is located beneath the Mosholu Golf Course in Van Cortlandt Park in the Bronx, on a nine-acre site four stories deep. Once complete, the plant will filter and dewater water, remove solids, disinfect it with chlorine and orthophosphate, and add fluoride to the water.
The cost of a water treatment plant in New York City varies according to the technology used. Depending on the contaminants, the equipment can range from $200 000 to $700,000 or more. It is important to note that the system must be able to handle wastewater 24 hours a day, 365 days a year. To keep the process running smoothly, it is essential to maintain a consistent monitoring process.
The city has a large watershed that supplies drinking water. In the past, the city relied on upstate communities for its water supply. The city’s watershed is approximately 2000 square miles or the size of Delaware. It is a significant source of drinking water for 9 million people in the city. The plant filters up to 10 percent of the city’s water and can filter much more. The water is blended with water from the western watershed of the Catskills. When construction began, it was not uncommon to hear about opposition and hatred toward the plant.
The cost of a water treatment plant in New York City is mainly dependent on the facility’s design. EPA recommended the combined sewer overflow tank design, but the city chose a different design. A city’s design may include a nutrient-disinfecting plant, costing hundreds of billions. The city plans to dredge contaminated discharges from private property.
The city has been sued for the botched renovation of its water treatment plant, and a lawsuit could help soften the blow for ratepayers. The money from the lawsuit could be used to reduce the principal amount owed for the sewage plant. The city has received $15 million in state grants, but the project is still far from being settled. Additional federal money could also reduce the cost of the project for users.
In addition to the lawsuits, the city has been required to invest in environmental protection through the Safe Drinking Water Act. While the new law prevents certain chemicals, it limits their use. It is believed that high concentrations of chlorine damage water delivery system fittings. Fortunately, the city is implementing voluntary and regulatory actions to address these issues. A new filtration plant will cost about $6 billion today, and maintenance will cost approximately $250 million annually.
Size of a filtration plant
The federal government has mandated that major surface water systems filter water and protect watersheds. New York balked at the request to build a filtration plant for Croton, citing the financial hardship. The Giuliani administration proposed placing the project beneath a golf course in Van Cortlandt Park. But city officials said that the project’s costs had far exceeded estimates. They also put the job out to bid during the high competition for construction labor and materials.
Water in the Croton watershed in Westchester, Putnam, and Dutchess Counties is more contaminated than that from the Catskill-Delaware watershed. In addition, storm runoff from the Croton watershed reaches 12 reservoirs in the city, containing more contaminants than the water from the latter. Before 2008, this water was routed directly into distribution. However, today, it is diverted north to a filtration plant, where it receives several treatments.
Work required at a filtration plant in New York City
A filtration plant in New York City requires the construction of massive pumps, holding tanks, and miles of electrical wiring. The plant also requires the construction of two raw and two treated water tunnels. The total cost of the project is approximately $2.8 billion. Workers are exposed to the elements while working in 600-foot-long concrete caverns. Many are allowed to work with music playing in the background.
The Croton Watershed has an extensive NYC suburb. The DEP is limited in its ability to purchase land for this project. Thus, the DEP relies on secondary protection in acquisition agreements. While the water quality of the Croton Watershed meets health standards, it is aesthetically degraded. A filtration plant would correct this problem and ensure that the city’s water supply would continue to meet surface water regulations.
The construction of a filtration plant in New York City is expensive, but the benefits far outweigh the expenses. Fortunately, the city’s watershed has been protected since 1997 by a Land Acquisition Program. Additionally, the state and federal governments have exempted the city’s water supply system from mandatory filtration, saving the city $10 billion in the long run. The plant also provides clean water to 8 million people.
A filtration plant in New York City would cost the city $10 billion to build. To operate the plant, the city would spend at least $100 million a year. The filtration plant would require a significant increase in water bills. The city is currently filtering about 10 percent of its water. And with such a high-volume operation, customers would likely bear the cost of the plant.
The filtration plant will clean the water supply for 8 million New York City residents and one million upstate customers. New York’s water supply is sourced from reservoirs and three controlled lakes that straddle the Hudson and Catskill rivers. A filtration plant for this city would cost $10 billion to build and another $100 million per year to operate. The city’s taxpayers would bear this cost.
Despite these challenges, the Croton Water Filtration Plant will improve the water supply in NYC and provide flexibility for the city’s water system. The City’s watershed is a significant factor in maintaining high-quality drinking water. Environmental watchdog organizations like Riverkeeper protect the Hudson River and NYC’s watershed. EPA-approved filtration plans also require strict turbidity standards.
The plant was completed in 2016. Nineteen reservoirs in New York City provide the city’s water supply system. In addition, older watersheds east of the Hudson need filtration. The Catskill/Delaware Aqueduct, which has six significant reservoirs and is approximately 125 miles northwest of Broadway, supplies the city with unfiltered bulk water. The plant is run by the New York City Department of Environmental Protection.
