June event: Plant Tour of New York City’s
Croton Water Filtration Plant
Updated 6/19.

Details on this past event from the AIChE's ChEnected blog.

: Saturday, June 18th, 10 am - 12 noon (Arrive before 10 am)

Venue: Van Cortlandt Park beneath the Mosholu Golf Course, Bronx, NY. Address: 3701 Jerome Avenue, Bronx. Directions by Car / By Subway (#4 line to Woodlawn, final stop).

Special Instructions: Dress code is long pants with construction boots, since the venue is still a construction site. If attendees plan to drive, they must provide their license plate number, when they register. Must be over 18 years old.

It’s the largest single construction contract in New York City’s history, according to www.water-technology.net, and the Croton water filtration plant will soon begin service (in 2012). We will get a sneak peak of the project in June, in a special Saturday plant tour.

Once completed, the plant will represent a significant step in improving the water quality of the one million New Yorkers who rely on the Croton water system – the city's oldest – which first began service in 1842.

We have arranged for this tour with NYC’s Department of Environmental Protection and key contractor Hazen & Sawyer. Thank you both for your help.

Being built entirely underground and requiring deep excavation and extensive rock boring to provide the necessary water tunnels, the four-storey plant will ultimately treat around 1.2 million cubic meters a day. This represents roughly 10% of New York's daily requirement – though the plant will be able to increase its throughput to supply around 30% in times of drought or severe need.

The new plant is to be the first water treatment plant actually located within New York City’s boroughs. It’s being constructed at a 12-acre site in the Bronx, within
Van Cortlandt Park beneath the Mosholu Golf Course – with ten acres being turned back into a municipal golf course on completion.

Water treatment will involve stacked Dissolved Air Floatation (DAF)/ filtration – the combination of a DAF loading rate of 50 gpm and a dual media filter containing 60 cm anthracite, 30 cm sand being chosen to optimise particulate removal. DAF sludge skimmed solids will be dewatered by centrifuge before disposal. The filtered water is then disinfected by treatment with UV (ultra violet light) and chlorine. After treatment, the water will be chemically adjusted as required and subsequently dosed with ortho-phosphate for corrosion control and hydrofluorosilicic acid to add fluoride.

Times: Saturday, June 18th 10 am - 12 noon
