President’s Message

CH2M HILL is pleased to announce the launch of an exciting partnership with National Geographic Education. One of the major initiatives of National Geographic Education is Geography Awareness Week, celebrated Nov. 14 -20. The focus of Geography Awareness Week this year is freshwater, and CH2M HILL has partnered with National Geographic to bring our water knowledge to the classroom. Working with National Geographic, one of the world’s leaders in scientific and cultural research, is a unique opportunity to help students and the public grasp global and local water management and supply issues.

Through our support of Geography Awareness Week, we hope to help develop future water stewards. Our technical experts contributed to the development of the resources being used to educate students about water. It is gratifying to know that thousands of educators and students will benefit from our professionals’ expertise. The water education materials created for Geography Awareness Week are suitable for use year ‘round.

Water managers in cities all over the world go to great lengths to plan and prepare for the public’s current and future water needs, but water is a finite resource. The focus on freshwater during Geography Awareness Week shines the spotlight on how individuals can act locally to help water resources globally.

CH2M HILL is committed to protecting the world’s limited water resources and proudly supports Geography Awareness Week’s mission of educating the next generation of culturally and environmentally aware global citizens. We hope you’ll join us.

Additional information and outreach materials are available online at

Stay safe,

Where to See Us

The fall conference season is in full swing. In September the City of Montreal was host to the International Water Association’s World Water Congress, an organization where CH2M HILL’s Chief Technology Officer Glen Daigger is now at the helm. Glen’s two-year term began at the close of the conference. We wish him much success leading this impressive organization. WEFTEC, which recently wrapped up, proved to be an exciting knowledge and networking building experience. During the conference CH2M HILL Technology Fellow emeritus, C.P Leslie Grady Jr., PhD, PE, DEE, received the Water Environment Federation (WEF) Industrial Water Quality Lifetime Achievement Award and CH2M HILL staff were part of an Operations Challenge team from Fayetteville, Ark., that competed admirably to represent their state.

See what we’re up to year ’round by following us on Twitter, Facebook, and reading our Access Water Blog.

WERF Study Offers Improvements for Sludge Handling

CH2M HILL has completed the Water Environment Research Foundation’s (WERF’s) project 05-CTS-3 Evaluation of Processes to Reduce Activated Solids Generation and Disposal. The goal of this project, which began in 2007, was to establish a comprehensive evaluation methodology for waste activated solids (WAS) reduction processes. This methodology was based on an in-depth consideration of a select number of technologies thought to be representative of the many options currently available in the municipal and industrial wastewater treatment marketplace. These technologies cover activated sludge process reconfigurations aimed at:

-Reducing the generation of residual solids from the liquid treatment process and
-Pre-conditioning WAS to make it more amenable to a subsequent stabilization process, such as anaerobic digestion

This study has improved the understanding of the mechanisms related to why some sludges are more susceptible to these technologies than other sludges. Designers and operators of treatment facilities will find this body of knowledge important as they move to optimize systems by:

-Producing higher quality effluent and better quality sludge
-Increasing in-plant energy production
-Decreasing life-cycle costs

WERF will publish the study in mid 2010. Julian Sandino, CH2M HILL Vice President and Technology Fellow and International Water Association (IWA) Fellow, discusses the project and practical application further in his blog from the IWA World Water Congress, “Increasing Biogas Production and Reducing Sludge Yields.”

CH2M HILL Employees Inducted into NACWA Hall of Fame

Four of this year’s inductees to the National Association of Clean Water Agencies’ (NACWA) Hall of Fame have CH2M HILL roots. Pictured from left to right: Edward Wagner/NYC, Senior Project Consultant; Alan Ispass/DCA, Vice President and Global Director of Utility Management Solutions; alumni Michele Pla and Charles “Tom” Gibbs were all inducted at NACWA’s Summer Conference and 40th Anniversary Celebration in San Francisco.

According to NACWA, inductees were chosen for their actions and commitment to the organization and for making a significant positive impact on either the evolution of the association or its ability to effectively represent the interest of the clean water community.

Natural Treatment System Earns Industry Recognition

Freedom Park, a water quality park located in Naples, Fla., was the winner of Southeast Construction magazine’s Award of Excellence for Best Engineering in the Civil/Public Works category. CH2M HILL, working for the Collier County Board of County Commissioners, designed the water treatment park to help save the Naples Bay from harmful pollutants and alleviate flooding problems in surrounding areas. At 50-acres, Freedom Park is a natural water quality treatment facility.The manmade park features an interconnected system of multi-depth ponds, polishing marshes and restored wetlands that function as a natural filtration system similar to the Everglades. Water is cleaned as it travels through both manmade and natural wetlands.

CH2M HILL was responsible for engineering, planning, permitting, and architectural design for the park. “Through a system of created lakes and wetlands the park will help reduce neighborhood flooding and help clean runoff before it flows into the Gordon River and eventually Naples Bay,” says CH2M HILL project natural treatment scientist Jim Bays.

The park also will provide a number of recreational and educational uses and includes a 5-acre lake and 12 acres of constructed wetlands, with approximately 6,500 feet of trails including 3,500 feet of boardwalk.


Promoting water quality education

Each fall we celebrate World Water Monitoring Day™, an international education and outreach program that builds public awareness and involvement in protecting water resources around the world by engaging citizens to conduct basic monitoring of their local water bodies. The program is hosted by the Water Environment Federation (WEF) and the International Water Association (IWA), two professional organizations in which CH2M HILL is very active. CH2M HILL has supported World Water Monitoring Day (WWMD) since 2003. We support WWMD because we share a common mission to preserve and enhance the global water environment.

“World Water Monitoring Day is an ideal community outreach program for our company,” said Bob Bailey, President, CH2M HILL Water Business Group. “The program focuses public attention on the water sanitation part of our business and spotlights the great work our clients do to protect water resources. In addition, CH2M HILL colleagues are able to participate in a shared cause around the world. This volunteer outreach program provides a significant opportunity for us to partner with clients, local officials and other community stakeholders to strengthen relationships and benefit our local communities.”

In 2009, over 120,000 people in 81 countries monitored their local waterways. Celebrate with us on September 18, or host your World Water Monitoring Day anytime from March 22 until December 31.

Cool Projects

Innovative approach developed for wet weather treatment at wastewater facilities

CH2M HILL is providing detailed design engineering services to North Texas Municipal Water District (NTMWD) to upgrade and expand their Wilson Creek Regional Wastewater Treatment Plant (RWWTP). With continued growth of the service area, anticipated low phosphorus effluent requirements, and the increased challenge of wet weather flow management, CH2M HILL developed an innovative strategy to increase dry weather treatment capacity from 48 mgd to 64 mgd, provide biological treatment for all wet weather flows up to 168 mgd and provide tertiary treatment to meet a future anticipated phosphorous effluent limit of 0.1 milligrams per liter and reduced total organic carbon levels.

The proposed treatment approach uses high-rate clarification (HRC) in a dual-function mode to achieve tertiary treatment during dry weather conditions while also providing additional secondary clarification capacity to a reconfigured activated sludge process during wet weather events. A high-rate ballasted flocculation system (Actiflo) is used for the tertiary application, and is converted to a secondary clarifier (BioActiflo) configuration during wet weather events to provide additional biomass separation capacity for the activated sludge process during the high flow conditions. In the BioActiflo mode, return activated sludge (RAS) from a plant’s secondary process is routed to a short contact time basin where it blends with excess wet weather flows. The mixture of biomass and influent wastewater is then treated through the high-rate chemically enhanced clarification facilities.

This wet weather approach provides secondary treatment by providing biological treatment of all flows and will be the first full-scale facility in the world being permitted for the BioActiflo process. This project will set precedence on how regulators approach wet weather treatment requirements at wastewater treatment facilities nationwide.
