Projects

The City of Hollister, Calif., selected Veolia Water North America (Chicago) to manage its new $100 million water reclamation facility under a 10-year public-–private partnership. The contract calls for the company to manage the 7900-m3/d (2.1-mgd) membrane bioreactor facility, along with a significant water reclamation system and associated services. These services include grounds maintenance, water reuse and recycling, emergency response, odor control, computer management and maintenance systems, laboratory work, and management of the septic receiving station.

The treatment process for the new wastewater plant consists of an influent lift station, preliminary treatment, activated sludge treatment, membrane separation process, disinfection, water inventory management, and biosolids treatment.

 

The South Adams County (Colo.) Water and Sanitation District has selected a Web-based, geographical information system and integrated asset management solution to manage and maintain its infrastructure assets. The district chose VUEWorks, manufactured by VUEWorks Inc. (Concord, N.H.), a tool that helps municipalities and other organizations track the condition, minimize failure risk, optimize expenditures, and improve service delivery of their assets.

 

Construction to replace approximately 0.40 km (0.25 mi) of pressurized pipeline in the Hawaii Kai section of Honolulu began in September. Hawaii American Water (Honolulu) will replace the critical section of line, which conveys wastewater to the company’s East Honolulu Wastewater Treatment Plant. According to manager Lee Mansfield, replacement of this pipeline is necessary because, at 50 years old, the existing pipe has nearly reached the end of its useful life.

 

In October, the upstream fish ladder located at the Thompson Falls (Mont.) Hydroelectric Plant was deemed ready to pass fish. The $7.5 million precedent-setting fish ladder is the first full-height fish-passage ladder in the United States built specifically for the bull trout, a threatened species.

The fish ladder is designed to provide rare species of trout and other fish varieties unhindered access to hundreds of miles of the upstream Clark Fork River and its tributaries. The fish ladder is part of the federal operating license for the electric utility PPL Montana (Billings, Mont.) to be in compliance with the Endangered Species Act.

The project was developed as a collaborative effort through an interagency, multidisciplinary team composed of PPL Montana; the U.S. Fish and Wildlife Service; Montana Fish, Wildlife, and Parks; the Montana Department of Environmental Quality; the Federal Energy Regulatory Commission; the Confederated Salish and Kootenai Tribes; GEI Consultants (Portland, Ore.); and others.

 

Johnson County Wastewater (Olathe, Kan.) this fall announced that the upgrades to its Douglas L. Smith Middle Basin Treatment Plant will result in water quality improvements that reach beyond local streams. Black & Veatch (Overland Park, Kan.) designed the upgrade, which was completed this summer.

The project increased capacity, improved wet weather treatment and odor control, and added biological nutrient removal capabilities. To provide supplemental carbon for the nutrient removal system, the utility decided to add a fermenter, rather than rely on chemical addition.

“Removal of phosphorus and nitrogen will now carry benefits all the way to the Gulf of Mexico, where government and environmental agencies strive to reduce problems related to oxygen deficiency,” said John O’Neil, general manager of Johnson County Wastewater.

The expansion also increased plant capacity to 54,900 m3/d (14.5 mgd) from 45,400 m3/d (12 mgd). Before the upgrade, the plant was processing 45,400 m3/d (12 mgd) through facilities originally designed to operate at 34,100 m3/d (9 mgd).

The utility was able to maintain operations throughout construction, which was led by BRB Contractors Inc. (Topeka, Kan.).

 

The Montana Department of Environmental Quality in September awarded Algae Aqua-Culture Technology (Whitefish, Mont.) a $350,000 grant to stimulate the development of Montana’s algae-to-fertilizer industry. The grant was offered under the American Recovery and Reinvestment Act of 2009 to begin building an innovative wood-chip-to-energy and fertilizer processing plant.

The company’s proprietary process uses a greenhouse-based algae growth system and an anaerobic biodigester to transform a blend of wood waste and algae into high-value methane for power generation, as well as into significant amounts of highly valuable organic fertilizer, according to Kathi Montgomery, Montana Department of Environmental Quality public education specialist.

 

The United Auburn Indian Community’s Thunder Valley Casino in Lincoln, Calif., installed PURON™ membrane bioreactor modules manufactured by Koch Membrane Systems Inc. (Wilmington, Mass.). The project will upgrade and expand capacity at Thunder Valley Casino’s existing wastewater treatment plant.

 

The U.S. Environmental Protection Agency has awarded $262,000 to the New Mexico Environment Department to administer the state’s water quality program. The program will prevent, reduce, and eliminate water pollution through biological and habitat data management and analysis, continuous water quality monitoring, and sediment and siltation data collection and analysis. The funds also will be used to train staff on water quality monitoring and assessment and to participate in a national wetlands survey.

 

Metro Vancouver, which provides the core services of drinking water, sewerage and drainage, and solid waste management to 22 member municipalities and one electoral area in British Columbia, announced that it has selected Trojan Technologies (London, Ontario) to provide the ultraviolet (UV) drinking water disinfection system for the Coquitlam UV Disinfection Project.

The company will supply TrojanUVTorrent™ reactors equipped with TrojanUV Solo Lamp™ Technology for the project. The system will be sized to treat 1.2 billion L/d (317 mgd).
