The Consulting Engineers of Ontario (CEO; Toronto) honored Hatch Mott MacDonald (Iselin, N.J.) with two Awards of Merit, one for the King Road Grade Separation project and the other for the Niagara Tunnel project. The CEO Awards of Merit program applauds projects that enhance economic, social, and environmental well-being in Ontario and around the globe.  
The King Road project required separating the road from three Canadian National Railway mainline tracks. Hatch Mott MacDonald developed an innovative open-cut, bridge-jacking technique that minimized disruption to the community and resulted in substantial costs savings for the clients. 
The Niagara Tunnel was bored by the world’s largest hard-rock tunnel boring machine, 140 m (460 ft) below the City of Niagara Falls, Ontario. Built in a tourist-sensitive environment, the tunnel has an excavated diameter of 14.4 m (47 ft) — the height of a four-story building. The project was completed almost 10% under budget and 9 months ahead of schedule, with half the average provincial rate of lost-time injuries and zero life-threatening injuries.  


Three organizations — Water for the World™, a joint Borealis Group Inc. (Vienna) and Borouge (Abu Dhabi, United Arab Emirates) corporate social responsibility program; Water and Sanitation for the Urban Poor (London); and the Organization of the Petroleum Exporting Countries — have joined forces to supply Mukuru Sinai and Korogocho, informal settlements in Kenya near Nairobi, with improved access to drinking water. This will be achieved through network design using high-density polyethylene pipe (HDPE) pipes and prepaid water dispensers to provide water more cost effectively. 
According to Borealis, using HDPE pipes will reduce the non-revenue water lost due to leaks and illegal connections that affect Nairobi City Water and Sewerage Co.’s financial ability to supply informal settlements around the city. The expected lifetime of these pipes is three times as long as existing pipes and higher durability results in fewer pipe break, less contamination, fewer leaks, and lower maintenance costs.  


Two of Florida’s water management districts — the Southwest Florida Water Management District (SWFWMD; Brooksville, Fla.) and the South Florida Water Management District (SFWMD; West Palm Beach, Fla.) — awarded indefinite delivery/indefinite quantity contracts to Stanley Consultants (Muscatine, Iowa). 
Stanley Consultants will provide district wide professional engineering services through task orders for up to 5 years. The scope of service includes water conveyance systems design, permitting, and construction inspection, as well as infrastructure assessments. 
Past work for the SWFWMD includes inspection of several water control structures, including southwest Florida’s largest water control spillway, as well as engineering services for a large discharge replacement structure on Lake Hancock, and construction inspection on several projects. 
Stanley Consultants also was selected as a subconsultant to Carollo Engineering (Walnut Creek, Calif.) to provide professional engineering services to SFWMD. The contract is for a 3-year period with two, 1-year options to renew. Work orders will be issued on an as-needed basis. Restoration task orders covered by the work orders could include stormwater treatment areas, flow equalization basins, reservoirs, and their associated appurtenances.  


Stanford University (Stanford, Calif.) broke ground in March on a facility that will test promising technologies for recovery of clean water and energy from wastewater. 
The new facility is a collaborative effort among university water-resource specialists and faculty researchers from the Stanford Woods Institute for the Environment and the Stanford-led Engineering Research Center for Re-inventing the Nation’s Urban Water Infrastructure. 
The facility is funded by the university and by a gift from Stanford alumnus William Codiga and his wife, Cloy. Called the William and Cloy Codiga Resource Recovery Center at Stanford, the facility’s mission is to accelerate commercial development of new wastewater technologies by testing at a scale large enough to demonstrate a process’s effectiveness and to stimulate investment for full-scale implementation. The center also will test technology that is mobile and can be deployed at remote locations.  

The Los Angeles Department of Water and Power (LADWP; Los Angeles) has partnered with Veolia Environnement (Paris) to review current practices and help implement industry best practices for the city’s large water meter and fire service line programs, as well as its chemical procurement activities.   

Veolia will use industry benchmarking techniques to develop cost and operational analyses for the city’s large meter repair and maintenance program. Large water meters represent approximately 1% of the total number of meters within the LADWP system, but account for nearly 20% of the utility’s annual revenue.  
Following a competitive request-for-proposal process, LADWP determined Veolia was the best partner to help the agency continue to increase its efficiency. After an initial assessment period, Veolia will recommend improvements in the water meter maintenance program and provide training and implementation support on the recommendations and best practices LADWP chooses to adopt.      

The City of Baltimore awarded SAK Construction LLC (O’Fallon, Mo.) an $18.8 million contract to install more than 18,000 m (59,000 ft) of small-, medium-, and large-diameter cured-in-place pipe in residential neighborhoods in the Union Square area of the city. SAK’s Atlantic Division office in Arbutus, Md., will oversee the project. 
Extensive project preplanning has begun, which also requires SAK to rehabilitate manholes, renovate lateral lines, and complete spot repairs. The assignment, part of a comprehensive plan the City of Baltimore is implementing to improve its wastewater system, is scheduled for completion in late 2015.  


Oldcastle Precast (Atlanta)  supplied approximately 3048 linear m (10,000 linear ft) of specially designed, precast, concrete box culvert and precast pipe for a segment of a $25.8 million emergency water restoration project designated by the National Resources Conservation Service. The Cache Water Restoration Project in Cache County, Utah, involved the reconstruction and improvement of approximately 9.7 km (6 mi) of mostly open, unlined channels that make up the Logan, Northern, Hyde Park, and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access. 

The project was designed and constructed according to a contracting method called construction management general contractor, which utilizes an integrated team approach. This method includes both preconstruction and construction-phase services. The project team included Cache County, National Resources Conservation Service (Washington, D.C.), J-U-B Engineers Inc. (Boise, Idaho), MWH Global (Bloomfield, Colo.), Hansen, Allen & Luce (Midvale, Utah), and Whitaker Construction Co. (Brigham City, Utah), who all worked in tandem. 
The Cache Water Restoration Project was spurred by a fatal 2009 landslide that killed three people living in a home below an irrigation canal. The canal hugged a steep hillside in Logan, Utah, and the tragedy prompted its total reconfiguration.   

The project was a 3-year process to reconfigure the canals. The revamped Cache Valley canal system came in under budget and ahead of schedule.   


The Berkeley County Public Service Sewer District (Martinsburg, W.Va.) executed a contract to install CleanB™ systems, manufactured by BCR Environmental Corp. (Jacksonville, Fla.), at four of its water resource recovery facilities (WRRFs). The changes upgraded the WRRFs to Class B biosolids production. The district chose to install the CleanB™ systems as a lower capital and operating cost alternative to aerobic digestion. 

Located on the Potomac River, Berkeley County is part of the Chesapeake Bay watershed, the largest estuary in the U.S. Excess nutrient runoff is a major challenge facing the bay, and almost three quarters of the its tidal waters are considered impaired by chemical contaminants. The district currently is undertaking an ambitious improvement program to reduce nutrient discharge. 

BCR’s CleanB™ Solution will enable the district to reduce its effect on the bay watershed. When land applied, CleanB™ Class B residuals enable soils to better retain nutrients.    

A recent flow monitoring project, conducted by RJN Group Inc. (Wheaton, Ill.), will enable the Urbana & Champaign (Ill.) Sanitary District to better understand the wet-weather flow conditions in three aging interceptors and one relief sewer. The project will identify what flows come from upstream tributary sewer basins. RJN Group is conducting a 90-day flow monitoring program with flowmeters at four locations. They will measure, record, and analyze flows to develop a wet-weather inflow/infiltration (I/I) analysis. The I/I analysis will include inflow peaking factors, regression analysis for peaking factor prediction, scattergraphs, hydrographs, and capacity analysis. 
During the metering period, RJN also is performing site inspections and routine calibrations. The district will be able to view the flow monitoring data online throughout the 3 months.  
A dry-weather flow diversion study by RJN immediately preceded this project. The dry-weather project helped the district determine minimum flow rates at specific locations within its system.  
RJN also is assisting the district to update five permanent flowmeter installations to current flow meter technology.  
The flow monitoring and I/I analysis was scheduled for completion last month.  


American Water Resources (Voorhees, N.J.) and Nashville Metro Water Services (Nashville, Tenn.)launched a partnership to offer service line protection programs to an estimated 143,000 residential customers in Davidson County, as well as portions of Rutherford and Williamson counties in Tennessee. American Water Resources’ water and sewer line protection programs educate homeowners about service line responsibility and help protect them from the potentially high cost of unexpected repairs to service lines.  

Nashville Metro Water Services issued a request for proposals from qualified providers for service line protection programs in 2013; American Water Resources was awarded the contract for the eligible properties in the Nashville area. 


Therma-Flite (Benicia, Calif.), a solutions-oriented, sustainable technology company focused on wastewater treatment and resource recovery, announced the expansion of its El Dorado, Ark., facility. The expansion will be completed in two phases and will more than double the square footage of the location. 
Therma-Flite’s current 3716-m2 (40,000-ft2) facility manufactures drying systems to turn Class B biosolids into Class A biosolids. 
Construction of the first phase began in late April. The success of this venture can be accredited to the cooperative efforts of the City of El Dorado, the El Dorado Economic Development Board, the Union County Industrial Board, the El Dorado Chamber of Commerce, and the Arkansas Economic Development Commission. In 2 years, Therma-Flite should achieve its goal of creating 50 jobs because of the joint support.  


The Village of Ridgewood Biogas Renewable Energy Project in Ridgewood, N.J., recently received the Renewable Energy Project of the Year award from the American Biogas Council (ABC; Washington, D.C.).  
The Ridgewood project won Biogas Project of the Year for its unique characteristics as the only municipal biogas system that was 100% privately financed and fully self-sufficient in its energy supply. Renewable energy is produced onsite by the anaerobic-digestion process that captures methane and converts it to power. The project lowers the village’s carbon footprint and converts wastes to valuable resources for local use.  
HDR (Omaha, Neb.) is leading the project in partnership with Natural Systems Utilities (Hillsborough, N.J.) 
The ABC Awards recognize projects that have a significant effect on the development of the biogas industry.
