Remember The Jefferson Starship Song “We Built This City On Rock and Roll”? Well, We’re Going To Put A Green Spin On It.
Let’s take a trip into the future in a multi-part series utilizing green innovations. Some of these ideas and innovations were the green subjects of previous Forced Green articles. Although these innovations can be used for brand new projects, in this series we will rebuild and transform a dying, decayed, and ruined city into a thriving, sustainable, and enjoyable metropolis. We will start underground and work our way up.
Part One : Subterranean
News reports have been full of stories of pipeline explosions killing scores of people, and devastating communities, or tons of fresh water lost to ruptured water lines. So for a safe solution to the deadly and environmentally destructive problem of age-degraded and structurally defective pipe systems, New Green City utilizes a method called cured-in-place pipe (CIPP) lining. For energy, sewer, and water pipelines et al, in both residential and commercial applications. It effectively relines the original pipe to create a new jointless pipe within the existing pipe without digging up roads and impacting traffic and area businesses for excessive amounts of time.
With a 100-year design life, CIPP’s trenchless method has the capability to rehabilitate pipes ranging in diameter from 6 to 96 inches (15.2cm – 2.4m). It is a fast process that uses a fiberglass tube coated wth epoxy resin that’s inserted into a damaged/old pipe and pulled through, easily negotiating bends and joints, then blown up like a balloon and cured with steam or hot water. After a few hours, the epoxy hardens like steel and creates the pipe within a pipe that is better and stronger than the host pipe. Reducing the pipe’s diameter by only about one-eighth of an inch (3mm), CIPP actually helps the flow capacity because there are no joints or seams that can separate over time. Depending on the depth of the dig, the cost comparison between the conventional “dig and replace” method could range from around the same to 2 or 3 times cheaper with the CIPP process. (More info on CIPP at Insituform Technologies – ).
Today we know that there are as many as 11 major gyres across the world’s oceans, and all of them are potential vestibules for the world’s trash. Plastic trash endures for a very long time and it’s a global issue. To stop New Green City from participating in that ecological debacle all storm drains have debris-stopping filters installed. 10,000 devices will keep at least 700,000 pounds of trash per year from flowing into the water-ways.
The filters have a retractable screen on the drain that opens where water and trash go, and a second screen inside the drain captures all the detritus (loose material like rock fragments or organic particles) where periodically city maintenance workers will vacuum out all the waste.
… Stay tuned for Part Two…. as the green future unfolds.
