The American Water Works Co. Inc. (Voorhees, N.J.) announced that it is part of a team that has received a grant from the WateReuse Research Foundation (Alexandria, Va.) to conduct a joint research project to develop “green” building guidance for the water-reuse industry. The project title is “Guidance for Implementing Water Reuse in New Buildings and New Developments To Achieve LEED Sustainability Goals,” according to a company press release.

American Water Works is teaming with Hazen and Sawyer (New York) and Alliance Environmental LLC (Hillsborough, N.J.) to develop guidance and planning tools to enable engineers, policy-makers, planners, and developers to make decisions on how to incorporate reclaimed-water projects into new buildings and developments.

The total value of the project is $185,927, with $124,834 funded by the WateReuse Research Foundation, in addition to a $61,000 in-kind contribution from the research partners.

 

The Tullahoma (Tenn.) Utilities Board (TUB) selected Mueller Systems (Cleveland, N.C.) to upgrade its water and electric infrastructure with an advanced metering infrastructure network and water and electric smart meters.

Mueller Systems will provide TUB with the Mi.Net® Mueller Infrastructure Network for Utilities, a two-way advanced metering infrastructure network, as well as Hersey water meters and solid-state electric meters for more than 19,000 service connections.

TUB is a customer-owned utility that provides water, electric, and wastewater services to a population base of approximately 25,000 people. At press time, TUB was scheduled to begin installing the advanced metering infrastructure network and the new meters in September.

 

The U.S. Environmental Protection Agency (EPA) awarded $534,000 to the City of Lincoln, Neb., for improvements to the Theresa Street Wastewater Treatment Facility. The grant will cover nearly half of the total project costs.

The project will improve the efficiency of existing anaerobic digesters by increasing the quantity of biogas produced. Three additional pumps and internal piping improvements will provide for greater mixing efficiency of the digesters’ contents. The additional gas production will increase the amount of electricity and heat generated by the existing electrical cogeneration equipment by 5%, according to an EPA press release.

The project also includes efficiency and energy improvements to the existing aeration system used in the biological treatment process. The treatment system aeration piping and process control system will be modified to reduce overall electrical energy used for aeration at the facility.

The upgrades are expected to be completed by spring 2013.

 

Beginning in October, villages in Senegal began using solar-powered water-filtration systems developed by Pall Corp. (Port Washington, N.Y.) to help stem the high incidence of fluorosis among the local population. The Aria™ Pure systems will provide an independent water source for more than 3000 people in Ndiaffate and Dankh Sene villages. The filtered water will be 98% free of fluoride which, in high concentration, causes tooth and bone decay.

The installation is the culmination of an 18-month pilot test, which involved more than 1000 hours of onsite testing under harsh conditions. It was conducted in Senegal’s Ndiaffate Villages in partnership with the University Cheikh Anta Diop in Dakar and the local Discalced Carmelites community.

The filtration units can produce water at a rate of 500 L/h (132 gal/h), and no pretreatment or chemicals are needed for operation.

 

The Rockingham Desalination Research Centre at Australia’s National Centre for Excellence in Desalination in Perth, Western Australia, officially opened Sept. 4. The facilities were designed to foster collaboration between researchers and industry in the development and prototyping of new desalination technologies. The world-class facility is flexible and modular in design to enable the testing of multiple novel technologies. It also is highly instrumented for research efficiency, scalability, and reliability of results, according to a CH2M Hill (Englewood, Colo.) press release.

The National Centre for Excellence in Desalination, which is on Murdoch University’s Rockingham campus, was established to provide research and development of desalination technologies and solutions to address Australia’s unique water needs.

CH2M Hill was the lead design consultant for the piloting facility and provided conceptual design for the center.

 

In September, a new, 454,000-m3/d (120-mgd) water treatment plant began providing Tampa Bay (Fla.) Water customers with drinking water that exceeds federal and state drinking water quality standards. The Tampa Bay Water Regional Surface Water Treatment Plant was expanded and upgraded through the largest design–build–operate drinking water project in U.S. history.

Veolia Water North America (Chicago) designed, built, and will operate the new plant. The new plant will use a multibarrier process that includes ballasted flocculation, ozonation, filtration through granular activated carbon gravity filters, disinfection, chemical dosing, and solids processing.

During the project’s first phase, the design–build–operate methodology led to a cost savings of $80 million on what was originally projected to be a $200 million budget, according to a Veolia press release.

 

The Des Moines (Iowa) Water Works (DMWW) selected Woolpert (Dayton, Ohio) to provide a 5-year, $2.5 million contract to develop an asset management system for the water utility. The multiphase approach will include planning, data conversion, system configuration, testing, application development, systems integration, and training.

The company will help DMWW establish best management practices, implement the Infor™ Enterprise Asset Management (EAM) system, and integrate EAM with key business support systems, according to a Woolpert press release.

DMWW serves approximately 400,000 customers in Des Moines and surrounding communities.

 

The Aquapolo Ambiental water reuse project in São Paulo, Brazil, is scheduled to start up this month. The project is the largest wastewater reuse project in the Southern Hemisphere and the fifth largest of its kind in the world. Upon completion, this facility will free up enough drinking water to continuously supply a population of 350,000 inhabitants, with the potential capacity to reach 600,000.

The new plant will employ Koch Membrane Systems’ (Wilmington, Mass.) PURON™ membrane bioreactor technology, as well as MegaMagnum® reverse-osmosis membranes.

The new treatment plant will be built on the grounds of the ABC Sewage Treatment Plant of Sabesp, located on the boundary between São Paulo and São Caetano do Sul counties.

The initial 2012–2014 phase will produce 56,000 m3/d (14.8 mgd) of reuse water, eventually reaching a capacity of 86,300 m3/d (22.8 mgd). Sixty-five percent of the plant output already has been sold under a 34-year contract to Quattor, a petrochemical company located within the Mauá petrochemical complex — Aquapolo’s target market.

 

W2E Organic Power (Columbia, S.C.), Ciycor LLC (New Lenox, Ill.), and Eisenmann Corp. (Crystal Lake, Ill.) announced a teaming arrangement to construct and operate a state-of-the-art anaerobic digestion facility in Columbia, S.C. The 48,000-Mg/yr, 3.2-MW anaerobic digestion facility will process organic waste, turning it into “green” natural gas for electric power production.

The facility will begin construction under the supervision of W2E Organic Power. Ciycor will be co-developer and financial partner. Eisenmann will provide the anaerobic digestion technology and engineering.
