Natural Treatment System in Oregon receives 2015 Water Quality Improvement Award

Roseburg Urban Sanitary Authority’s Natural Treatment System in Roseburg, Oregon, was presented with the 2015 Water Quality Improvement Award during WEFTEC. The award is presented annually to the water quality improvement program that best demonstrates significant, lasting and measurable excellence in water quality improvement or in the prevention of water quality degradation in a region, basin or water body. CH2M designed and managed the Natural Treatment System for RUSA. Mark Madison, agricultural engineer and principal technologist, blogs about the project and explains how it benefits the local river.

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.

Progress in Natural Treatment Systems Technology Showcased in Shanghai

This month, CH2M HILL Natural Treatment Systems Principal Technologist Jim Bays presented on state-of-the-art findings on wetlands treatment during the International Water Association International Conference on Wetland Systems for Pollution Control. In his latest blog, Bays shares highlights from his presentations and reflects on the opportunities available in the natural treatment wetlands industry.

Demonstration Wetlands Prove Treatment and Reuse of RO Concentrate for Benefit to both Society and Nature

The City of Goodyear had been looking for a cost-effective alternative to sewer discharge for reverse osmosis (RO) concentrate disposal. Like many cities in the central valley of Arizona, Goodyear is diversifying its water supply, and therefore, constructed a large RO facility to create potable water from brackish groundwater supplies. However, with RO treatment comes the challenge of RO concentrate disposal, which has increased the salt and hydraulic load at the nearby water reclamation facility. A solution was needed to treat this brackish concentrate. In response, CH2M HILL, Reclamation, and the City of Goodyear developed the Goodyear Pilot Wetlands project, which imagines a process of wetland treatment to remove metals and nitrogen from the concentrate, and then to blend the treated concentrate with treated reclaimed water for discharge into natural riparian wetlands and eventually to the Gila River. In his latest blog, CH2M HILL's Jim Bays discusses a pilot-scale demonstration project that was developed.

Achieving Sustainable Nutrient Removal for Tailored Water Treatment

CH2M HILL's Zeynep Erdal discusses her paper "Achieving Sustainable Nutrient Removal for Tailored Water Treatment: A Novel Application of the MBR Technology”that was presented this week at WEFTEC and the pilot study conducted to examine using MBR technology for more complete nutrient removal process for secondary effluent end-use.
