Management of New York City’s Watershed Michael A. Principe, Ph.D. Deputy Commissioner New York City Department of Environmental Protection Bureau of Water Supply October 10, 2005
Presentation Outline • Development of NYC’s Watershed Protection Program • Costs and Funding • Contractual Mechanisms Supporting Watershed Protection • Major Program Elements
Primarily a surface water supply • 19 reservoirs & 3 controlled lakes • System Capacity: 550 billion gallons (over 2 billion kiloliters) • Serves 9 million people (1/2 of population of New York State) • Delivers approx. 1.2 billion gallons (4.5 million kiloliters) per day to the City • Source of water is a 2,000 square mile (5,180 square kilometer) watershed in parts of 8 upstate counties • Operated and maintained by NYCDEP
CATSKILL AND DELAWARE SUPPLIES • Located primarily West of the Hudson River • Rural, mountainous watershed • 70% forested, low population, significant agricultural uses • Shallow soils and porous rock produce high quality water • City has Filtration Avoidance Determination for these supplies
Governmental Agencies Involved in Watershed Protection • Program involves agencies from: • Federal (USEPA) • State • New York City • 8 upstate counties • 60+ towns and villages • Crosses multiple jurisdictions, all outside of NYC • New York has strong “home rule” tradition
Issues Driving City to Watershed Protection • The Safe Drinking Water Act of 1986 and the Surface Water Treatment Rule of 1989 established objective and subjective criteria for avoidance • Concern over whether City could meet subjective criteria • City owned less than 8% of watershed • City regulations outmoded • City alarmed by potential cost of filtration plant (originally estimated at $4-8 billion) • Firm belief by NYC that reliance on end-of-pipe solutions alone is not prudent; best approach is to protect quality of water at its source
Development of Watershed Protection Program • DEP received first filtration waiver from EPA in 1993 • Waiver conditioned on implementation of protection programs • DEP designed comprehensive monitoring program to assess threats to water quality • Based on assessment of threats, management programs designed and implemented
Watershed Memorandum of Agreement • MOA established collaborative approach between City, State, watershed residents, environmental groups and regulators • Signed in 1997 • Allowed City to proceed with Watershed Regulations, Land Acquisition and Partnership Programs • City had to agree to fund programs
Contractual Arrangements • DEP contracted with local public, private and non-profit entities to use City ratepayer funding to implement programs • Groups include Catskill Watershed Corporation, Agricultural Council and county agencies • All contracts subject to City procurement rules
Catskill Watershed Corporation • MOA created the Catskill Watershed Corporation (CWC) • CWC comprised of local representatives • Voting rights apportioned based on percent of land in watershed • CWC provided with $160+ million of City funding for wastewater, stormwater and economic development programs
How is Watershed Protection Funded? • DEP is funded by water and sewer rates • Revenues and expenses are managed by the New York City Municipal Water Finance Authority, an independent entity established in 1984 • Revenues collected by the Water Finance Authority are independent from other NYC funding and cannot be diverted to other NYC programs • The Water Finance Authority collected $1.7 billion in 2004. $900 million of this was used for water supply operations and debt service
Water & Sewer Rate Structure • Water rate = $1.65 per 100 cubic feet • Average single-family house pays about $220/year for water • Sewer rate = $2.62 per 100 cubic feet • Consumption decreased by nearly one-third since 1980s due to conservation • NYC rates are lower than most major US cities including Dallas, Los Angeles, Washington, Boston and Atlanta
Types of Watershed Protection Programs • Protection Programs – Designed to prevent future degradation of water quality; large scale and evaluated over the long-term. • Remediation Programs – Designed to address specific problems and are expected to result in measurable decreases in pollutants; small scale and evaluated over the short-term.

Major Watershed Protection Program Elements • Land Acquisition Program • More than 385,000 acres (156,000+ hectares) solicited • 68,000+ acres (27,660+ hectares) acquired/under contract • 21,000+ acres (8,565+ hectares) under contract for Agricultural Easements
Major Watershed Protection Program Elements • Partnership Programs • 2,000+ failing septic systems remediated • Nearly 50 stormwater retrofits funded • 44 stormwater BMPs installed • Wastewater Treatment Plants (WWTPs) being upgraded to tertiary treatment (25 WOH, ~70 EOH) • 7 new WWTPs being constructed • Watershed Agricultural Program • 2900+ Best Management Practices (BMPs) implemented • 1,775 miles (2,857 km) of stream buffers protected through Conservation Reserve Enhancement Program • New initiatives on small farms and EOH farms
Major Watershed Protection Program Elements • Watershed Rules and Regulations • Updated in 1997 to address WWTPs, septic systems and stormwater runoff • Designed to protect sensitive areas: streams, wetlands, reservoirs and steep slopes • 1,000s of projects reviewed to date • Coordinated field inspection and patrol with Engineering and NYCDEP Police • City funds most costs of compliance
DELAWARE RESERVOIR BASIN • Heavy agricultural uses • 4 large wastewater treatment plants • Excessive nutrient loading to reservoir led to eutrophication
