2 Agenda 1. About NYC DEP 2. Carbon Footprint 3. Water Footprint 4. Resiliency 5. Green Approaches and Integrated Water Management 2

3 About NYC DEP DEP is the largest combined water and wastewater utility in the United States, with 6,000 employees and an annual budget of more than $1 billion. WATER SUPPLY WASTEWATER TREATMENT AIR, NOISE, HAZ WASTE 3

4 Sustainability Planning DEP is proactively reducing greenhouse gas emissions, stormwater runoff, and drinking water demand, and preparing for the impacts of extreme weather to drinking water and wastewater infrastructure. Oct May 2008 Apr Sep Jun

5 City Government GHG Emissions Gray infrastructure is costly and GHG-intensive, which has led NYC to explore new opportunities for cost-effective green infrastructure that achieves multiple benefits 2006 to 2013 City Government Annual GHG Emissions by Sector Annual GHG Emissions (Million tc02e) 5

6 OneNYC The City of New York is working to solve sustainability challenges in real time 6

7 OneNYC While integrating multiple goals of GHG reduction, energy neutral wastewater treatment plants, and sending zero waste to landfills Reducing GHG Organics and Recycling Achieving Multiple Goals Zero Waste Stringent Regulation 7

8 DEP GHG Emissions DEP is analyzing and implementing measures to reduce GHG emissions, increase energy efficiency, reduce waste, and become more resilient through the use of renewable natural gas DEP GHG Emissions Profile 800,000 [CELLRANGE] [CELLRANGE] 700, , ,000 [CELLRANGE] [CELLRANGE] [CELLRANGE] 400,000 35x25 Target 300, , ,000 80x50 Target 0 FY06 FY08 FY15^ FY17* Electricity WWTP Process N20 (in-city & Upstate) Landfill Methane Natural Gas FY06 BAU ProjecRon for FY17 ^FY15 Preliminary Data *FY17 Projected Data WWTP Methane (ADG) DisRllate Fuels, Kerosene & Propane TransportaRon (Cars, Trucks, Marine Vessels, Helicopters) Steam 8

10 Water Footprint: Population Growth DEP has been working towards a 5% or 50 MGD goal for reductions in demand in order to promote drinking water resiliency 1,600 Calendar Year Demand (MGD) New York City Population 8.4 million , Water Demand (MGD) 1,400 1,300 1,200 Average Daily Distribution (MGD) 2008: 1, : 1, : 1, : 1, : 1, : 1, : * Population (Millions) 1, : 1,045 MGD 1, Official 2013 New York City Department of City Planning Estimate

11 NYC Water Demand Management Program DEP is implementing strategies for reducing water demand to reduce water usage to near historic levels, even in the face of population growth 11

12 Water-Energy Nexus: Filtration Avoidance Watershed protection is an integral part of filtration avoidance, but a Filtration Avoidance Determination (FAD) is not a given 12

13 Extreme Events and Impacts: Water Supply Climate change and extreme weather events put additional pressures on DEP infrastructure Tropical Storm Irene, August 2011 Water spills over the Gilboa Dam in Gilboa, NY Aug. 29,

14 Extreme Events and Impacts: Sewer & Wastewater A boat washed onto the premises of the Coney Island Wastewater Treatment Plant after Superstorm Sandy, October 31,

15 Investing Now Saves Money Later $1.1 billion of vital infrastructure is at risk. Investing $315 million in construction of strategic fortification can save the City $2.5 billion in emergency response costs over the next 50 years. 15

27 Water Footprint: NYC Water Supply System The NYC water supply watershed extends far beyond the city, and water is conveyed, mostly by gravity, to and throughout the city via a flexible, redundant network 27

28 Wastewater Resiliency 28

29 Water Quality in the NYC Harbor and Tribs By the 1980s, sewage pollution had degraded the quality of NYC waterways. Nearly three decades and $2 billion later, water quality has drastically improved HIGHER RES IMAGE AVAILABLE? 29

30 Water Quality in the NYC Harbor and Tribs = does not meet water quality standards (pathogens/do) 75% of Harbor meets pathogen standards for swimming 19% meets standards for boating and fishing 7% of our Harbor is made up of tributaries that do not meet secondary contact standards 30
