A team of contractors teaming up on a project to modernize the nearly century-old Canoe Brook Water Treatment Plant in Short Hills. The $78 million venture has been named one of New Jersey’s Leading Infrastructure Projects by the NJ Alliance for Action, a non-profit statewide coalition of more than 2,500 business, labor, professional, academic and government leaders advocating infrastructure investment throughout the state.
Overseen by New Jersey American Water, the project at Canoe Brook Water Treatment Plant amounts to a near-total redo. The plant’s existing infrastructure dates back to the 1920s and will be completely replaced with a new state-of-the-art facility predicted to provide residents with up to 15 million gallons of water per day. The project is scheduled to be completed by early summer 2012.
The overhaul incorporates an environmentally sensitive design that includes premium-efficiency pump motors; high-efficiency lighting fixtures and use of natural lighting and water efficient plumbing fixtures. It also includes filtering systems, chemical treatment systems and ozone disinfectants for the plant. Ozone water treatment is being increasing used in the US for drinking water treatment with about 2 billion gallons per day treated with ozone.
To ensure Metropolitan Water District of Southern California’s imported water supplies continue to meet increasingly stringent state and federal regulatory regulations, the district is investing more than $1 billion to retrofit its five treatment plants to ozone water treatment. The two-year spending plan calls for $143 million for continued retrofits at the district’s Robert B. Diemer plant in Yorba Linda and the Weymouth plant, with $4 million in work remaining at the Robert A. Skinner and Henry J. Mills treatment plants in Riverside County.
Water Factory 21 (WF21), Orange County Sanitation District (OCSD), was dedicated in a 1977 and transforms secondary municipal wastewater into water that exceeds drinking water standards. In 1991, the Orange County Water District (OCWD) was granted a California Department of Health Services permit to inject 100 percent reclaimed wastewater into a potable water aquifer without blending.
In early 1997, Orange Country planned and constructed the world’s largest indirect potable reuse system which was completed in 2008. The 70 MGD facility will eventually produce 130 MGD. It employs micro filtration, reverse osmosis and advanced oxidation treatment.
The facility has won many awards and has demonstrated that municipal wastewater can be reclaimed for uses up to and including potable water supply. It has served as a model for other agencies and encouraged the development of water reclamation around the world.
The Otter Lake Water Commission has submitted is plan, as well as a loan application for nearly $2 million, to the Illinois Environmental Protection Agency (IEPA) public water supply loan program. The Otter Lake commission is responsible for water treatment and for the distribution systems that transmit water to 467 individual and nine wholesale customers in an area that includes Auburn, Divernon, Girard, Pawnee, Thayer, Nilwood, Glenarm, Tovey, South Palmyra Rural Water District, Henderson Rural Water District and rural customers.
The commission in 2010 completed a $6 million expansion to the water treatment plant on the east side of Otter Lake just west of Girard, IL. The additional money will allow the plant to meet a new requirement for the cryptosporidium parasite that will require additional treatment. The microscopic parasite can cause diarrhea and more severe complications, particularly in children or people with immune-system disorders.
The commission had engineering studies done to determine the most cost-effective way of removing the parasite, as well as controlling taste and odor. Based on those evaluations, an ultraviolet light system with advanced oxidation process was selected.
The project is scheduled for completion by October 2013.
The new Gateway Hotel, attached to the Gateway Theater of Shopping Center in South Africa, shares mortar with 380 stores, 38 restaurants, more than a dozen cinemas, a science fair, a funfair, an art gallery, a fantasy forest, a theater, a rock-climbing wall, a sports arena and the biggest man-made stationary wave in the world. The Gateway Hotel is also designed to be both green and highly energy efficient.
The efficient lighting solutions are not just about using low-energy bulbs. Atrium light wells facilitate natural light penetration. This, combined with a thermal-performance glass, ensures that air conditioning loads are kept as low as possible, since direct heat-energy transmission through the glass is controlled. To stop rooms overheating, which would prompt guests to turn on air conditioners, external shading devices have also been used. The iconic “leafy” screen surrounding the hotel is a particularly efficient shading technique that ensures solar shielding of the northern facades of the building.
Some of the other green features include regeneration-drive lift systems, heat-pump technology, variable-speed drive installations that optimize motor systems, and an ozone water-treatment system that reduces the need for chlorine.
