London’s ‘Super Sewer’ Finally Underway To Help Stop Waste Flowing Into Thames : News : TravelersToday

Workers have started the construction of London’s “super sewer” in an effort to reduce the waste that goes into the Thames river. The project’s goal is to address the waste problem that the city has especially with its growing population. Currently, a hole is being dug at the new tunnel’s center.According to City A.M., workers from Tideway have started digging a 30-meter diameter hole to mark the new tunnel’s central point. The hole is as big as the dome at St Paul’s Cathedral while the tunnel has a length of 16 miles.Just this year, about 1.2 million tons of sewage waste has been dumped straight into the Thames river due to the fact that the old Victorian sewers can’t handle the huge amount of waste that flows through it. BBC reported that the old tunnels’ waste would overflow to the river even if it would just rain for a few millimeters.The proposal for the Thames Tideway Tunnel isn’t a recent one because it has been floating in the air since 2005. However, there were some issues that needed to be clarified with regards to the contracts so the go-signal for the project’s construction was given on February 2015.

World Water Day 2016: About

World Water Day is an international observance and an opportunity to learn more about water related issues, be inspired to tell others and take action to make a difference. World Water Day dates back to the 1992 United Nations Conference on Environment and Development where an international observance for water was recommended. The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day. It has been held annually since then. Each year, UN-Water — the entity that coordinates the UN’s work on water and sanitation — sets a theme for World Water Day corresponding to a current or future challenge. The engagement campaign is coordinated by one or several of the UN-Water Members with a related mandate.

4 New Renderings Imagine Scaffolding as Beautiful Installations – CityLab

Construction sheds—what most regular city folks call scaffolding—cover some 200 miles of New York City sidewalk, infecting the metropolis with dark green boards and unnerving shadows. For the most part, construction sheds are both monotonous and everywhere, which is why the New York Building Congress launched a competition last summer to redesign them completely.And the results are in! A committee of real estate, architecture, and construction specialists, including a top official in the city’s Department of Design and Construction, have reviewed 33 construction shed proposals and selected four winners. The designs will be evaluated by the New York City Department of Buildings for code compliance, according to Commissioner Rick Chandler, and could be used by city developers in the future

Colas Paves Future Roads With Solar – Forbes

It would be an understatement to say that the company’s executives were surprised when all of France’s major media showed up at the Colas trade show booth in mid-October.“It was incredible,” said Christophe Lienard, Colas’ Innovation Group Director. “Our work in road construction and maintenance doesn’t normally get that sort of attention.”The media were there because Colas debuted the world’s first road surface that generates solar electricity, called Wattway. The panels, which are only a few millimeters thick, can be installed on top of any road surface without any additional civil engineering work, withstand all types of vehicle traffic, and every 20 square meters should generate enough energy to power a home.Five years ago, the project was nothing more than an after-hours experiment in an engineer’s garage.“He had a piece of road surface, photovoltaic modules, and some weights,” Lienard explained. “We knew it had to be possible, but we didn’t know how.”
