They dont think, oh, its something i drank last night. See the empire state building, right. Narrator the milwaukee incident thats 1,000 feet. Pointed out the potential vulnerability so you figure, you go down 1,000. Of our Drinking Water infrastructure in controlling the spread of illness. Biedrzycki its incumbent upon us how high that is thats how far we go down. To try to stay ahead of the curve, but its very, very difficult. Theres always another bug on the horizon. Narrator in 2008, the Associated Press reported that Water Quality testing across the nation uncovered trace amounts of pharmaceutical compounds narrator stretching more than 60 miles under the city, in the Drinking Water supplies of millions of americans. Tunnel 3 is taking generations of workers to complete. The Health Effects of these low levels of medicatio
Hecht what has happened because of the restoration we can preserve a water supply. Is the water overflows its banks, conservation of water is a way of generating more water. It floods into these nice flood plains with native plants. Allbee we think that a household can actually reduce and then slowly the water percolates back down into the stream. Its water usage by about 30 . And thats hugely important in terms of the amount narrator this allows the land to naturally filter of infrastructure that communitys going to require. And clean the sewer overflows before they enter the river. Narrator las vegas is one of the fastgrowing areas in the country. The restoration included extensive environmental changes its a relatively new city under constant construction. To improve the stream and infrastructure changes to reduce the csos into the watershed. Hecht when i first started talking with people but because its in the arid mojave desert, about stream restoration, i kind of imagined people
And complex engineering. Man water is essential to the economic viability of new york city. Reliable infrastructure and Reliable Delivery of water is a must. You have to reinvest in the infrastructure every single minute to keep it current. Hurwitz we have the stock exchange, we have the United Nations failure can have a dramatic impact on the nation, and even internationally. So theres a really keen awareness that you always have to be fixing the system. Things corrode, they rust. They get to where you turn them on and nothing happens. But it is so totally used in every nook and cranny, that making any accommodation to shut it down, to do something to it, is very difficult. Narrator two Massive Underground tunnels, called simply tunnel 1 and tunnel 2, provide most of the citys water supply. They run hundreds of feet below manhattan, far deeper than the subways. Built at the beginning of the 20th century, they are concretelined and bored through solid rock. They could last centuries. B
Engineers in the 1950s discovered rust on the tunnels valves. There were concerns that if they closed the valves for tunnel inspections, they may never open again, leaving new york city without water. So they chose to keep them open. As a result, there has not been significant inspection, maintenance, or repair of the tunnels in decades. No one knows their current condition. Hurwitz currently, city tunnel 1 and city Tunnel Number 2 would be feeding each half of the city. So youd lose half the city if you didnt have a replacement. Narrator without half of its water supply, the city would shut down. For nearly 40 years, new york has been in the process of constructing a solution. Man this project is water Tunnel Number 3.
