* Eliminating the leaks in Wawarsing. During the construction of the bypass tunnel, the Delaware Aqueduct will be shut down, enabling DEP to enter upstream portions of the tunnel and fix cracking at three segments totaling nearly 500 feet in Wawarsing by injecting grouting from the inside of the tunnel near the affected areas.
DEP has been investigating the potential leak impact in Wawarsing since the day it was first observed. While the investigation was underway, DEP, with the Ulster County Health Department, has taken water samples, photographs, met with homeowners, and, with the United States Geological Survey, created an extensive monitoring network and began hydrogeological mapping.
DEP has also attended public meetings on the issue as well as forming a Public Advisory Committee to help keep the community informed about efforts to monitor and repair the tunnel. While studies have been ongoing, New York City has assisted homeowners with sump pumps, ultraviolet disinfection, bottled water, and funds for stormwater improvements.
* Preparing the water supply system to handle the repair. Before the repair is performed, DEP is building or upgrading several key pieces of crucial infrastructure that will help maintain the city's water supply capacity during the construction of the bypass tunnel, including: completing the construction of the Croton Filtration Plant in the Bronx, which will provide up to 290 million gallons per day of filtered water - up to 30% of the city's water needs; upgrading the Cross River and Croton Falls pumping stations to provide increased water capacity; upgrading the New Croton Dam, which will allow for increased water storage capacity; and the connection of the Catskill Aqueduct and Delaware Aqueduct, which will allow the city to send water from the Delaware Watershed system into the Catskill Aqueduct, providing increased capacity and flexibility for the water supply. The city is also upgrading its groundwater system in Queens to increase the water supply for the future, as part of its program for long-term reliability and sustainability of the water system.
Mayor Bloomberg has made planning for the repair of the Delaware Aqueduct a pivotal part of the PlaNYC goal to improve the reliability and long-term sustainability of New York City's water infrastructure. Mayor Bloomberg has made a larger commitment to maintaining and improving the City's water system than any administration in history. Approximately $21 billion has been allocated for water system capital projects, including:
* $2.5 billion invested and committed to City Water Tunnel No. 3 - more funding for the tunnel than the previous five administrations combined;
* Acquisition of nearly 79,000 acres of land upstate to protect the city's watershed - allowing New York City to remain one of only five large cities in the country to obtain the majority of its water from unfiltered sources;
* $2.8 billion for the Croton Filtration Plant, which will filter drinking water from the Croton Watershed;
* $1.6 billion for the Ultraviolet Disinfection Facility, which will provide an extra level of drinking water protection for water from the Catskill and Delaware Watersheds;
* and approximately $6 billion for upgrading the city's 14 wastewater treatment plants and more than $1 billion to reduce combined sewer overflows, which has helped bring harbor water quality to an all-time high since testing began 100 years ago and allowed wastewater treatment plants to meet the Federal Clean Water Act's secondary treatment standards for the first time ever.
DEP manages the city's water supply, providing more than 1 billion gallons of water each day to more than 9 million residents, including 8 million in New York City, and residents of Ulster, Orange, Putnam and Westchester counties. New York City's water is delivered from a watershed that extends more than 125 miles from the City, and comprises 19 reservoirs, and three controlled lakes. Approximately 7,000 miles of water mains, tunnels and aqueducts bring water to homes and businesses throughout the five boroughs, and 7,400 miles of sewer lines take wastewater to 14 in-city treatment plants.
