CH2M HILL

Water Treatment

CH2M HILL utilizes state-of-the-art water treatment technology to help you deliver high quality drinking water to the communities you serve. We are leaders in the use of membranes, granular activated carbon, high rate clarification processes as well as ultraviolet light and ozone for disinfection. Through our bench and pilot testing facilities, we work with you to select the best treatment process to meet your current needs, while maintaining flexibility for future regulatory and water quality goals.

When combined with other technologies and services (water supply, water distribution, economics and rate studies, management consulting, GIS, decision science, contract operations, alternative project delivery and many others), CH2M HILL can provide solutions for all of your water treatment needs.

Water Distribution

Water distribution systems today are impacted by the rapid growth and development of communities, the increased consumer interest in water quality, aging water infrastructure, recent and emerging regulations, and the implementation of security and counter-terrorism measures. Your distribution systems must deliver water that is safe, meets drinking water regulations, has adequate service pressure, meets fire flow requirements, and achieves customer satisfaction. Our Water Distribution System Core Technology covers the delivery of finished water from the exit point of the water treatment plant (or any other treated water source) to the customer's tap. Services designed to assist you with your water distribution needs include:

• Hydraulics
• Master planning
• System optimization
• Water loss prevention
• Modeling
• Sampling
• Water quality analysis

Membrane Filtration

CH2M HILL has unparalleled experience in the application of membrane processes to the treatment of drinking water. Beginning with the design of the Cape Coral, Florida water treatment plant in 1977 we have applied our membrane expertise to solve a wide variety of water quality challenges faced by our clients in meeting their potable water demands. Our personnel have extensive experience in application of membranes for the following applications:

• Removal of particulates and organics from fresh surface and groundwater supplies
• Softening and organics removal from alluvial groundwater
• Desalination of brackish groundwater and seawater
• Removal of inorganic contaminants, including arsenic, fluoride and nitrate from groundwater
• Control of particulates, hardness, organics, and total dissolved solids from brackish surface waters

Water Reuse

The United Nations has identified water scarcity as an issue of principal concern for this century. Reuse or water recycling will be a critical strategy to address this need. CH2M HILL's commitment to and leadership in reuse began over thirty-five years ago, with the design and operation of the US`s first full-scale advanced wastewater treatment facilities for the South Lake Tahoe Public Utility District. Since that time CH2M HILL has been involved with a number of firsts in reuse technology.

Our projects range in size from demonstration/pilot projects to full-scale operational facilities, such as the landmark Upper Occoquan Sewage Authority Regional Water Reclamation Plant, one of the world`s first and largest indirect potable reuse plants. Most recently CH2M HILL managed the internationally acclaimed NEWater reuse project for the Republic of Singapore. This landmark project successfully married advanced wastewater treatment technology with extensive public education and outreach. The result—public acceptance of indirect potable reuse, toasted with bottles of direct potable use water around the world and in Singapore.

As the world's leader in providing innovative planning, engineering, and communications applications for water reuse and recycling, CH2M HILL brings clients award-winning solutions in all market segments. Whether you are exploring reuse alternatives in urban irrigation for landscape, parks, and playing fields, in agricultural irrigation, industrial reuse, or habitat enhancement through constructed wetlands with or without indirect potable reuse, CH2M HILL can help. Our award-winning work utilizing recycled water in agricultural irrigation applications includes the reuse of treated wastewater for the Santa Rosa Subregional Water Reclamation System on pasture, vineyards, and other crops. These comprehensive efforts involved planning, conveyance, design, and assistance in irrigation scheduling and application.

For urban irrigation applications, we offer recent experience at the Bend, Oregon Prong Horn Golf Course where an innovative partnership between the city and High Desert Development Company linked a 2.5 MGD reuse facility to the city's wastewater treatment plant and executed a long-term purchase agreement to supply the reuse water for landscaping and golf course irrigation. The West Basin Water Reclamation Plant represents the best in our work for industrial reuse along with the Santa Rosa's Geysers Recharge Project which recharges groundwater prior to becoming steam for power. The Wakodahatchee wetlands (from the Seminole word for "created waters') are award-winning constructed reuse wetlands. This area restores the historical ecosystem function by using treated wastewater to create a popular wetland park comprised of native south Florida plant species, habitats and wildlife.

In cooperation with numerous progressive organizations, CH2M HILL has implemented over 500 reuse projects across the nation and around the world—all of which gives us the unparalleled depth of experience to deliver success. Distinguish your project as one of the industry's best—put our experts to work for you.
