Sewer gas. Sewer gas is a complex mixture of toxic and nontoxic gases produced and collected in sewage systems by the decomposition of organic household or industrial wastes, typical components of sewage. Sewer gases may include hydrogen sulfide, ammonia, methane, carbon monoxide, sulfur dioxide, and nitrogen oxides.
Improper disposal of petroleum products such as gasoline and mineral spirits contribute to sewer gas hazards. Sewer gases are of concern due to their odor, health effects, and potential for creating fire or explosions. In homes Exposure to sewer gas also can happen if the gas seeps in via a leaking plumbing drain or vent pipe, or even through cracks in a building’s foundation. History Health effects Greenhouse gas contribution Fully vented sewer gases contribute to greenhouse gas emissions. Sewer gas can be used as a power source, thus reducing the consumption of fossil fuels. Impact on sewerage See also References Detroit A City In Decay.

Every family, every community and every business needs infrastructure to thrive.
Infrastructure encompasses your local water main and the Hoover Dam; the power lines connected to your house and the electrical grid spanning the U.S.; and the street in front of your home and the national highway system. Once every four years, America’s civil engineers provide a comprehensive assessment of the nation’s major infrastructure categories in ASCE’s Report Card for America’s Infrastructure (Report Card). Using a simple A to F school report card format, the Report Card provides a comprehensive assessment of current infrastructure conditions and needs, both assigning grades and making recommendations for how to raise the grades. An Advisory Council of ASCE members assigns the grades according to the following eight criteria: capacity, condition, funding, future need, operation and maintenance, public safety, resilience, and innovation.

In 2011, ASCE commissioned a series of economic reports called Failure to Act to provide an objective analysis of the economic implications for the United States of current investment trends in key infrastructure sectors. What is the value to America’s economy in the long term if we invest in our infrastructure today? The results of the Failure to Act series focus on: Together, these reports cover 9 of the 16 categories addressed by the Report Card for America’s Infrastructure.

Nothing more than a quiet desk jockey assigned to survey some routine structural damage. Quickly though, your mission turns from a mundane trek to a fight for survival. Your tools are simple: the camera around your neck and the wits to navigate a virtual labyrinth of debris. How you tell your story is your choice, will you have the commitment to finish your duty, or will you ignore all else but the preservation of your own life? OK, so the premise isn’t as action-packed as swinging across a floating, racist city in “Bioshock Infinite” or no-scoping ultranationalist terrorists in “Modern Warfare 3.” It was actually America’s dangerously outdated roads and levees that inspired Loiste Interactive’s Oskari Samiola to create “INFRA.” Have a look at some more settings, and if you want to support “INFRA” head on over to Indiegogo.
A Gorgeous First-Person Video Game About Infrastructure Is Now Out on Steam. Take the brooding beauty and dystopian, Soviet-flavored setting of “Half-Life 2”—but remove the weapons and monsters—and you got yourself “INFRA,” a video game about fixing a crumbling city before everything goes to hell.
The first-person nonshooter will not appeal to everyone. The action begins in, of all places, a boardroom discussion—a narrative decision the game seems to instantly regret, because you get a pop-up option to “Skip meeting.” “Look, just text me the memos, I want this over with as soon as possible,” your character growls. Yet you might spend the next 7 minutes trying to find the dang exit of your office building, as did a guy who recorded the below play-through video. (He then fell off a ledge and died.) As for the plot, you are “Mark,” an engineer tasked with saving the infrastructure of a once-profitable, now badly degraded Baltic mining city. It might sound tame, but the unique mission and lovely, atmospheric graphics might appeal to a wonky slice of gamers.
