Yorkers every day and maintain 7,000 miles of water mains

• Protect our 2,000 square mile watershed, including 19 reservoirs and three controlled lakes

WASTEWATER TREATMENT• Treat 1.3 billion gallons of wastewater each day• Operate and maintain 14 plants, 96 pumping stations,

and 7,500 miles of sewers

Capital Construction

• 10-year Capital Plan: $19.4 billion

• Includes the Bureau of Engineering Design and Construction’s projects in construction or design

• Provide in-house engineering design and project management services for DEP’s water supply, distribution, and treatment divisions

Typical Design Evaluations

• Reliability• Vendor/Manufacturer Reliability• Operation Complexity• Maintenance Requirements• Durability• Expense (including lifecycle)

Energy Considerations Added

• GHG Emissions vs. Lifecycle Costs

• Level of GHG emissions

• Energy Consumption vs. Lifecycle Costs

• Criteria Pollutants

• Develop Energy Conservation and GHG reduction SOPs for all construction projects

• Develop Energy Operations and Design Policies: Design kick-off meetings, BODR, all design milestones, and Bid Docs

DESIGN CONSTRUCTION OPERATIONS

SOP and Policy Development

Policy Objectives

• Energy/GHG reductions from electro-mechanical processes

• Facility Layout (i.e. minimize pumping distances, blowers near discharge, etc.)

• Maximize ADG production and use• Control/Operational Strategies

(pumping, DO control)• Energy Source Conversion (heat recovery,

preheating sludge with digester effluent)• Process emissions and energy

(side stream treatment)

Design Services Goals

• Develop design options that consider energy• Generate an energy profile report• Baseline current condition energy consumption

and GHG emissions• Using direct measurements• Modeling• Predicted Future energy conditions via modeling• Perform an economic analysis for each option

Construction Phase

• Mindful of change orders• Identify modification that will affect energy/GHG• Existing analysis• New additions not previously investigated• Energy/GHG increases = 0 unless justified

Meeting Design Intent Operationally

• Identify the operational design intent with respects to energy and GHG emissions:

• Process (i.e. thickener operations or DO control strategies)

• Target operational set point• Maintenance requirements to keep

efficiencies high• Operational requirements:

Energy and systems monitoring

Evaluation Metrics

• Capital Cost per unit Energy Saved and metric ton of CO2(e) avoided

• Annual energy savings• Percent change in energy consumption and

GHG emissions• Simple payback• Lifecycle Costs (incl. O&M, escalation, and

useful life)• Net Present Value • Cash Flow Evaluation

Case Study: Hunts Point Resiliency

• NYC Wastewater Resiliency Program:• Hunts Point WWTP, Bronx, NY

• Minor flooding from Hurricane Sandy - floodwaters reached EL. +12.2 ft

• East River overtopped southern plant wall; flooded roadways• West Effluent Water Building flooded; electrical equipment

damaged

• 100-year flood event poses high risk of flood damage• Key strategies:

• Seal buildings• Elevate equipment• Construct flood barriers• Flood-proof equipment• Replace equipment as part of asset management upgrades

Case Study: Hunts Point Resiliency

• Energy efficiency improvements• Replace scum pumps in-kind

• Explosion proof

• Submersible

• Improved energy efficiency• Remove seal pumps entirely; no longer required for new

submersible scum pumps

• Sustainability KPIs• Energy = 20% reduction from baseline (existing conditions)• Emissions = 20% reduction from baseline (existing

conditions)

Case Study: Hunts Point Resiliency

Project is small with regards to energy reduction potential and had limited opportunities but…

IMPROVEMENTS WERE POSSIBLE

Case Study 2: Jerome Park Aqueduct

Rehabilitation

Case study: JRAQ-REH

• Jerome Reservoir and Aqueduct Rehabilitation, Bronx, NY

• Design complete, currently in final approval stage before going out to bid

• Purpose: improve water quality, improve site safety, maintain functionality of reservoir

• Scope of Work includes: • Structural rehabilitation

of reservoir walls• Repairs to retaining walls• Installation of diversion pipe• New fence and guiderail

between gatehouses 6 & 7• Roadway surface

and drainage improvements

Case study: Jerome Park Reservoir

SOP 056 Recycled and Regional Content for New Materials

• Purpose: Reduce embodied energy of new materials; reduce GHG emissions associated with transportation; and stimulate local markets

• Preliminary Sustainability Workshop sets initial KPI, e.g. 20% recycled / 60% regional (based on total weight (tons) of new materials)

• Design engineer required to evaluate recycled and regional opportunities

• What materials will be used?• Can they contain recycled content?• Where do they come from?

• Develop a Recycled and Regional Content Plan that summarizes likelihood of achieving goals set at PSW

• Did we meet our targets?• If not, can we identify further opportunities?• Do we need to adjust the goal?

• Submitted prior to Deep Dive Sustainability Workshop (SOP 051)

• Excludes mechanical, electrical, and plumbing components• For new materials only – construction waste is covered by

SOP 057

Case study: Recycled Content

• Data per 90% design submission and may change as design develops to final design.

• Note that this project started in 2016 – tables for capturing this information have since been updated and can be found in e-Builder.

• At DEP’s direction and to comply with NSF 61 Components, concrete that is in contact with potable water shall not contain recycled content (fly ash) due to potential leaching issues
