Jack Coogan - Building Scale Solutions: OCV Architects
Coogan is the RA and Principle at OCV Architects and spoke mainly about one specific project in the Bronx. The building consists of 18 units and his company reduced construction costs enough to install a rainwater collection tank. Calculating using NY's average annual rainfall of 49.7 inches, the roof's area of 2850 square feet, and a 95% capture rate (for a total capture of 80,000 gallons), they figured that each apartment could flush their toilet 9 1/3 times per day just on the grey water collected. After completing the project, however, they found that each unit actually flushes their toilet 25.5 times per day! So, the grey water mixes with fresh water to make up for the difference. With 1 cent per gallon water costs, and 1.3 gallons per flush, Coogan calculates an $800 per year savings (it is worth noting that the system cost $18,000 to install - 12 year pay back).
Susannah C. Drake AIA, ASLA - Rising Currents: A New Urban Ground
Drake spoke of a project she worked on with Stephan Cassell and Adam Yarinsky on the infrastructure issues that will result from sea level rise (climate change) in NY Harbor. They were one of five teams to participate in the challenge to create a solution to projected sea level rise of 6 ft (plus 18 feet for a storm surge). Each team was assigned one spot on the NY Harbor, her team focusing on the 500 acres that comprise lower Manhattan. Their calculations revealed that 21% of lower Manhattan will be covered in 100 years, with 68% susceptible to the storm serge.
We currently dump 500 million gallons of sewage water into the harbor each week! Their plan consists of permeable street beds with water proof vaults for cables and other lines. The tip of Manhattan would become an urban estuary (close to a swamp) and the east side would become a salt marsh with an urbanester and a sunken forest.

Tatiana More - Stormwater: Waste or Resource
"Silos of information, but no conduits."
According to More, the MTA uses 2.6 Billion gallons of potable water per year! The water filtration system was built on a plot of land with a high water table which had to be subsequently drained and then refilled - a huge waste! These two examples show some the inefficient manor in which things are done in NYC.
Her program, the NYCSWCD, works in consort with the SWIM coalition and measures soil moisture saturation, evapotranspiration rates, and does pollution analysis of their water absorption projects to find the most efficient solution for a specific area. She gave some details on specific projects they have done recently.
Thomas O'Connor - Stormwater Solutions REsearch: EPA Office of Research and Development
O'Connor works in the water supply and water resources division of the Urban Watershed Management Branch of the EPA. He works on management of wet-weather flows and the aging water infrastructure. The New Jersey office of R&D is 20 acres on which models are tested for optimization.
He spoke specifically of two projects they have recently worked on - one for semipermeable parking lots, and the other for green spaces which are meant to absorb extra water.
Sustain is an online decision optimization engine used by his office.
Questions for Consideration:
- How can we encourage CSR like that being practiced at Toto to come from all companies?
- How can we get people to understand the resources their using when they don't see where they come from and where their waste goes?
- Do we need to completely redevelop our infrastructure?
- What can we do about diverting more of NYC's sewage from the ocean?
- How can we communicate the level of urgency to the people who just don't care?
