Each year, millions of people in Bangladesh drink ground water that has been polluted by naturally high levels of arsenic poison. Finding safe drinking water in that country can be a problem. However, International Development Enterprises has a low-cost answer. This non-governmental organization has developed technology to harvest rainwater.
People around the world have been harvesting rainwater for centuries. It is a safe, dependable source of drinking water. Unlike ground water, rainwater contains no minerals or salts and is free of chemical treatments. Best of all, it is free.
The rainwater harvesting system created by International Development Enterprises uses pipes to collect water from the tops of buildings. The pipes stretch from the tops of buildings to a two-meter tall storage tank made of metal. At the top of the tank is a so-called "first-flush" device made of wire screen. This barrier prevents dirt and leaves in the water from falling inside the tank.
A fitted cover sits over the "first-flush" device. It protects the water inside the tank from evaporating. The cover also prevents mosquito insects from laying eggs in the water.
Inside the tank is a low coat plastic bag that collects the water. The bag sits inside another plastic bag similar to those used to hold grains. The two bags are supported inside the metal tank. All total, the water storage system can hold up to three-thousand-five-hundred liters of water. International Development Enterprises says the inner bags may need to be replaced every two to three years. However, if the bags are not damaged by sunlight, they could last even longer.
International Development Enterprises says the water harvesting system should be built on a raised structure to prevent insects from eating into it at the bottom. The total cost to build this rainwater harvesting system is about forty dollars. However, International Development Enterprises expects the price to drop over time. The group says one tank can provide a family of five with enough rainwater to survive a five-month dry season.
We can infer from this article the following points except that______.
选项
A、the problem of shortage of drinking water in other countries can be solved by applying the rain collection system
B、the collected rain water is safer to drink than the ground water
C、Bangladesh people are no longer upset about the shortage of drinking water
D、the rain collection device might also help to solve the problem of industry in shortage of water supply
答案
D
解析
推论题。综观全文,可以得知该储水系统的容量只能满足生活饮用水的需求,文中没有与可能用于工业用水相关的内容,故D项为正确答案。
