As the largest conference of its kind in North America and the largest annual water quality exhibition in the world, WEFTEC.08 offers access to the latest in water quality developments, research, regulations, solutions, and cutting-edge technologies.
This year's event – the Water Environment Federation's 81st annual technical exhibition and conference – will be held October 18-22 at McCormick Place in Chicago, IL.
Designed to address a diverse and comprehensive array of contemporary water and wastewater issues, this year's technical program of 115 technical sessions, 31 workshops and 10 facility tours are categorized into more than 20 technical education focus areas ranging from collection systems and leading-edge research to sustainable water resources management and water reclamation and reuse. To keep attendees up to date on the most pressing water quality challenges and solutions, the program also includes several "hot topic" workshops and "featured" technical sessions throughout the five-day event.
Hot topic workshops include discussion of green infrastructure, wastewater treatment systems to address climate change, strategic workforce planning and nutrient removal, among others. Featured technical sessions will focus on water scarcity issues, lab practices, Clean Water Act policies, and addressing water quality standards in long-term control plans.
The exhibition provides access to the latest developments, research, regulations, solutions, and cutting-edge technologies in the field. More than 900 exhibiting companies are expected in Chicago and have already reserved a record-breaking 281,000 net square feet of floor space at McCormick Place.
Other conference highlights include the Opening General Session, Operations Challenge, AEESP/WEF Scientist Luncheon and Lecture, WEFTeach, Global Center, poster presentations, award presentations, student activities, and the Utility Partnership Program.

With xp2D, all of xpswmm and xpstorm's familiar tools for generating tables, graphs, and animations are available for reviewing, analyzing and presenting model results. A powerful feature of the software using xp2D is its ability to dynamically link to any 1D (quasi-2D) model in an integrated fashion.

Modular roof systems
GreenGrid® modular green roof systems reduce the risk of flooding, sewer overflows, and subsequent discharges by retaining rainfall and delaying water runoff from roofs. Testing has shown that a GreenGrid Extensive (4") system retained 72% of 1" rainfall that occurred in a 15 minute interval. When the growth medium in the green roof does become saturated, the water slowly percolates through modules, and usually does not become roof runoff until several hours after peak flows from impervious surfaces have subsided, providing additional time for municipal sewer systems to handle other uncontrolled runoff.
