Office of Integrated Water Management
DEP’s Office of Integrated Water Management in the Bureau of Sustainability spearheads
policy development, innovative partnerships, studies, and pilot programs to reduce system
demand, protect critical infrastructure, increase cost efficiency, and promote public awareness.
Vision
• Integrated Water Management is a framework for managing NYC’s watersheds, water
resources, and water facilities in a sustainable, economic, and socially beneficial
manner
• Integrated Water Management leads to increased efficiency and operation of our utility,
enhanced livable communities, resilience against climate change, better land use
practices, and protection of public health

Overview & Goal: Water Challenge to Universities
Identical to previous Challenges, the New York City Water Challenge to
Universities will loosely follow the seven step Water Management framework that
the US EPA endorses on their WaterSense® website:
• Step 1: Making a Commitment
• Step 2: Assessing Facility Water Use
• Step 3: Setting and Communicating Goals
• Step 4: Creating a Water Conservation Campaign
• Step 5: Implementing the Water Conservation Campaign Strategies
• Step 6: Evaluating Progress
• Step 7: Recognizing Achievement
The 5% Challenge Goal: To meet the reduction goal, participants in the
University Challenge must reduce their water usage by at least 5% from their
baseline consumption. The baseline is two years of water usage prior to the start
of the Challenge.
![Page 11: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/11.jpg)
11
Program Structure: Water Challenge to Universities
1. Tracking Water Use. DEP will track all water usage through Automatic Meter
Readers (AMR) and provide participants with monthly reports.
2. Water Reduction Strategy. Participants will be encouraged to develop a
Water Conservation Campaign, mapping out a strategy to meet the Challenge
goal.
3. Regular Workshops. DEP will convene quarterly workshops to provide
updates on the Challenge and encourage the exchange of ideas, as well as
support new initiatives and/or to resolve issues as they arise.
4. One-on-One Meetings. As needed.
5. Promotion and Recognition. DEP will provide promotion and recognition of
the Challenge participants including press and news releases, and information
posted on DEP’s website.

Goals
• Important concepts
• Tracking water use online
• Tracking water use through a BMS
• Cooling tower wastewater allowances
![Page 18: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/18.jpg)

Important Concepts
• Units of Measurement
• Water meters register use in cubic foot units
• 1 CF = 7.48 gallons
• 100 CF (HCF) = 748 gallons
• HCF are billing units
• Who are DEP Customers?
• DEP can only have a business relationship with a property
owner, not a tenant
• Where do I find information?
• Most DEP billing rules are contained in the Water and
Wastewater Rate Schedule available online
![Page 19: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/19.jpg)

• 97% of water meters in
New York are read by an
Automated Meter
Reading (AMR) system
• Grey battery-powered
Meter Transmission
Units (“MTU”) are wired
to each meter and
mounted on the building
exterior
• Meters 2” and larger are
read hourly, smaller
meters are read four
times a day

27
Issues Affecting Measurement I
• Building water distribution – Down Feed Systems
o Most large buildings use a “down feed” system in which water enters the
building and is pumped to a roof tank.
o Water flows down from the roof tank to end users
o The meter is never directly measuring water end use, but rather the
frequency the roof tank is filled and that volume of water
o Daily consumption, or average hourly consumption is about as granular as
you can get with a down feed system
o Multiple tank refills overnight when there should be little or no use is still an
indication of possible leaks or excess use
o Meter resolution is not critical
![Page 28: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/28.jpg)
28
Issues Affecting Measurement II
• Meter Resolution
o Small service meters (under 1.5”) measure in 1 CF units
o Larger meters usually measure in 10 CF or even 100 CF units
o Some, but not all larger meters are now available with 1 CF output
resolution
![Page 29: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/29.jpg)

31
Tracking Water Use with a BMS
• Instrumentation industry has been slow in developing
interfaces to water meters that use absolute encoder
registers
• Some meter manufacturers offer models with dual output
(Separate DEP AMR and pulse outputs)
• Meter Interface Boxes are being tested by DEP: Separate
data to DEP AMR box and BMS ModBus connection or
pulse
![Page 32: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/32.jpg)
32
Meter Interface Boxes
• Ethermeter by SCADAMetrics
• Smart Meter Master by Meter Master (F.S. Brainard)
• Connects to meter and DEP MTU box
o Ethermeter: Modbus and pulse output
o Smart Meter Master: pulse, 4-20 ma, 0-10 v, other outputs
• Requires permit from DEP

Cooling Tower Wastewater Allowances
• Buildings with large evaporative cooling towers may
qualify for a sewer discount (“wastewater allowance”) on
the makeup water for the cooling tower
• Conditions:
oApplication form must be filed and a renewal application
must be submitted every two years ahead of the
expiration of the current wastewater allowance
oMeters must be up-to-date, i.e. the “master” DEP meter
cannot be outdated
oAll meters must have AMR boxes (MTU’s) – DEP installs
oThe account must be current
oCooling tower meter is owner’s responsibility
![Page 37: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/37.jpg)
37
Cooling Tower Wastewater Allowances
• Owner considerations
oMeters run slow (“under register”) as they age
oTo maximize the wastewater allowance the owner
should replace the CT make-up meter every 5-7 years
• Application Form
oDEP website: nyc.gov/dep
oCustomer Assistance > Customer Forms
![Page 38: New York City’s Water Challenge to Universities...• DEP’s Water-Energy Nexus Tool. 14 Benefits of Participation • Builds off of your Carbon Challenge successes and opens a](https://reader034.fdocuments.in/reader034/viewer/2022042213/5eb76aeffdc4e34de76ebb5d/html5/thumbnails/38.jpg)
38
Sub-Meters
• Very useful for monitoring possible excess water use:
o Boiler makeup
o Cooling tower makeup
o Food service and restaurant spaces
o Pools
o Laundries
o Any single-pass water-cooled equipment (generally illegal at this point)
• Required prospectively under the Administrative (Plumbing) Code for:
o Commercial cooking or laundry facility
o Commercial gym or spa
o Makeup to cooling tower or swimming pool
