NSU creates, manages and invests in onsite water treatment and reuse systems.
~25 onsite systems managed by NSU in the San Francisco North Bay region impacted by the recent CA fires.
~100 onsite systems currently managed by NSU in the Northeast, 80 within those areas directly impacted by Super- Storm Sandy.
ZERO NSU onsite facilities exceeded effluent permit requirements while many centralized facilities were down for weeks or longer. PA ME NY CT DE MD NJ VT NH MA RI

Integrated Water Reuse and Heat Recovery
1st residential water reuse project in the U.S.
We have been doing Onsite Water Treatment systems for 30 years, and in that time we have established ourselves as a leader in the decentralized or onsite reuse system space. This has allowed us to serve in long-term shared value partnerships for some very high profile developments & clients. A couple worth mentioning here…
Any football fans? Rams/Chargers? I am a lifetime supporter of the Cleveland Browns, so its with mixed emotions that I plug the NE Patriots here.
Gillette Stadium [NE Patriots]
The town of Foxborough did not have the necessary infrastructure for the proposed stadium.
Not only was the town unable to provide the additional 600,000 gallons of water required for operation of the stadium during game day, their central WTTP couldn’t handle the excess wastewater flow.
To enable the development and to bring this stadium to the community NSU designed, built, and continues to operate an onsite water reuse facility. This reduces demand on local infrastructure and provides water for toilet flushing and cooling at the stadium.
Battery Park City
BPC is a 92 acre redevelopment district which has adopted the mission for sustainable redevelopment.
The first project in NYC to incorporate wastewater reuse was the Solaire Building, which recycles 25,000 gallons of wastewater per day. The treated water is reused for flushing toilets in the 293-unit apartment building, cooling tower make-up water, laundry and garden irrigation. It has consistently achieved a 48% water consumption reduction and a 56% reduction in wastewater discharge
Due to the great success at Solair our services have expended to include six in-building systems for the various LEED certified buildings which are part of this lower-Manhattan district.
These systems have been running for almost 15 years.
The New School University, NYC
Located in Grenwich villiage in Manhattan
we designed built and currently operate a 40,000 GPD in-building onsite water treatment system & reuse that water for flushwater, cooling & laundry.
Hallets Point, Queens NYC
District scale development which will include the worlds largest in-building water reuse system
Finally - A little bit closer to home - Sonoma Raceway –
The client has their own onsite water and wastewater systems.
The existing system had great technologies but required an extensive amount of labor due to limited instrumentation and automation. NSU invested in plant SCADA which results in annual savings of 55% in operator costs compared with the manual systems.
We see ourselves as long-term shared value partners with the operations, and I think this is an excellent example of what that means for us and our clients

Hunters Point
San Francisco, CA
We see this project as the prototype of sustainable development.
400 acre, 6 million square feet mixed-use development of office and retail space, plus thousands of new homes and green space
It is one of the largest redevelopment projects across the country, NSU and the Project Team, lead by FivePoint/GI Energy, will develop a 420,000 gallon  per day water reuse facility as part of a sustainable ‘Eco-Grid’ solution, which will minimize the development’s environmental impact by providing integrated renewable energy, district-scale recycled water, and one of the largest geo-exchange heating and cooling systems in the country.

Working Session: Reuse Challenges & Solution Pathways
WATER & SEWER COSTS
AGING INFRASTRUCTURE
The cost from degrading water/wastewater infrastructure is expected to add up to $200 billion by 2020(1)
Example Challenge/Hurdle Introduction
Goals of Working Session
Create dialogue/collaboration between onsite and centralized system approaches.
Find common features and areas of alignment between the two groups.
Working Session Instructions
5 min: Introductions (Company/Centralized/Decentralized & scribe volunteer)
5 min: Create a list of hurdles for onsite reuse you learned about today or know about.
5 min: Create a list of hurdles for centralized recycling.
10 min: Create a path forward for onsite reuse and centralized recycling (5 bullet points on each side of the poster board)
5 min: 3 tables will share their results of collaboration with attendees.
Reception/Networking
Increased costs driven by increased maintenance costs, water scarcity, and reduced government subsidies
GREEN BUILDING INITIATIVES
CLEAN WATER ACT
TMDL’s(2) expose requirement for significant inland STP improvements. CSO/Stormwater & SSO issues very expensive to overcome
Demand and incentives for green buildings have increased dramatically over the past five years
LACK OF CENTRALIZED SEWER
INCREASED DEMAND
Water use has been increasing at more then twice the rate of population growth
A large percentage of cities still dump raw sewage into their water bodies
SAFE DRINKING WATER ACT
INCREASE ALTERNATIVE WATER SUPPLY NEEDS
Public health challenges were recognized within all aspects of our distribution system, including indoor plumbing
