Wet weather planning; joining it up with an integrated model

Case study from Odense, Denmark, shows value in using an integrated model approach to achieve river water quality objectives in wet weather planning. CH2M's Global Technology Leader for Wastewater Collection & Wet Weather Elliot Gill will present the paper, "An Integrated Model-based Planning Approach to Achieve River Water Quality Objectives in Wet Weather Using the Best Mix of Green and Grey Technologies," during the Water Environment Federation's Technical Exhibition and Conference (WEFTEC), on Tuesday, September 29. Join Elliot live in Chicago or read his Access Water blog for more information about implementing an integrated planning approach for solving wet weather challenges.

One World. One Water—CH2M participates in WEFTEC 2015

Next week, from September 26-30, CH2M will be headed to Chicago, along with more than 22,000 water professionals, to participate in all that WEFTEC, the Water Environment Federation’s Annual Technical Exhibition and Conference, has to offer. The conference, being held at McCormick Place, is the largest of its kind in North America. From technical presentations and workshops to networking with other industry professionals, we are looking forward to participating in WEFTEC 2015. CH2M's Global Leader for Wastewater Julian Sandino highlights the major activities CH2Mer's will be involved in during this year's conference.

Benefits of Evaluating CMOM Activities

In 1998, First Utility District (FUD), in Knox County, Tennessee, conducted a self-audit of its wastewater collection system, which identified opportunities for improvements, and since 2000 has invested in typical programs, such as capital improvement planning, grease control, root control, manhole inspection, sewer line cleaning, close circuit television, smoke testing, flow monitoring, sewer manhole and pipe rehabilitation, and pump station operation and maintenance, to successfully reduce the number and volume of overflows in its system. FUD and CH2M did a follow-up audit of the District’s CMOM (Capacity, Management, Operations, and Maintenance) program in 2013 to take a closer look at not only the documentation of CMOM activities, but also at the effectiveness of the program. Today at the 2015 WEF Collection Systems Conference, CH2M's Kevin Colvett and FUD's Patrick Spangler will present on the benefits of investing in the tools of CMOM and evaluating CMOM activities.

Data Mining for System Optimization and CSO Reduction

Data mining can improve system optimization and help utilities successfully reduce combined sewer overflows (CSOs) in their wastewater systems. Today, during the 2015 Water Environment Federation (WEF) Collection Systems Conference, being held in Cincinnati, Ohio, CH2M's Dingfang Liu, Vinta Varghese, and Eric Muir are presenting a case study from the Greater New Haven Water Pollution Control Authority, to share how the utility took a different approach to reducing CSOs to the City of New Haven, Connecticut's West River, during rain events.

GIS Tool Quantifies the Consequences of Overflow in Cincinnati’s Sewer System

The Metropolitan Sewer District of Greater Cincinnati’s (MSDGC) Watershed Operations Division, with support from CH2M HILL, has been working to develop a Decision Support System tool to evaluate the Triple Bottom Line (TBL) impacts of an overflow at individual locations throughout the city’s sewer system. This GIS-Based Operational Decision Support Tool uses GIS and spreadsheet tools to quantify the Consequences of Overflow (COO) for a set of metrics designed to evaluate impacts to the TBL. CH2M HILL Global Technology Leader Susan Moisio discusses the tool in more detail in today's Access Water blog.
