7 Ways Technology Will Provide Water for the World

smart-water-meterMarc-Schomann-3

Our ever-increasing population is stretching our ability to provide clean water for our needs, from agriculture and manufacturing to the most basic one of all: drinking water. But recent innovations in water technology may have some answers on tap to that problem.

1. Smart Water Metering:

Smart water meters go above and beyond the capabilities of the basic meter on the side of your house, enabling users to monitor their water usage more accurately (and only pay for the water they’ve actually used), and help water suppliers to identify leaks and thefts, as well as see where and when water usage is highest (and to charge accordingly).

Woosh Water is reinventing the drinking fountain

Water conservation is a huge concern in Israel and the rest of the Middle East. An interesting startup in Israel called Woosh Water is helping conserve water and reduce plastic consumption by reinventing the public drinking fountain with a high-tech and networked solution.

Woosh Water stations allow users to refill water bottles and reduce the consumption of disposable plastic water bottles.

The stations can be used by anyone, but the system works best when users join the network. After joining online, users receive a small keychain sensor to login when they refill their bottle. And because they are networked together, the Woosh Water Stations track how much water a user has consumed and how many plastic bottles they have kept out of the waste stream by using a reusable bottle, as well as how many all Woosh users have collectively avoided. This provides a social reward and incentive for people to use the system and encourage others to participate, as well. Read more

Unintended consequences: motors driven by tap water

The small electric motor was probably revolutionary than the electric light bulb; people could get light from gas or candles, but the motor led to the development of fans and home appliances, and changed the way factories were designed and goods were produced. But before there was universal delivery of electricity, there was tap water, and Kris De Decker of Low-Tech Magazine describes how water-powered motors did many of the same tasks.

crop-scale

In Europe, small motors using the public water supply appeared in the 1840s. In the US, they came into extensive use in the 1870s and 1880s. A water motor consisted of a small water turbine that was suspended in a metal casing. The diameter of the turbine runner could be anywhere between from 20 to 90 cm. Read more

15 Concepts and Solutions for Providing Clean Drinking Water

dancingwaterfountain

From low-tech to high-tech, concepts and solutions for providing clean drinking water are everywhere. Some are simple and portable while others are large and scalable, and we’re going to need all of these varieties of ideas in order to make sure that access to safe clean water is a right, not a privilege.

Using “Super Sand” to clean water:

Prevention of water pollution

trees-can-prevent-water-pollutionDealing with water pollution is something that everyone (including governments and local councils) needs to get involved with. Here are a few things you can do to help. Learning about the issue (like you are doing) is the greatest and most important step to take. Here are a few more:

You can help

Never throw rubbish away anyhow. Always look for the correct waste bin. If there is none around, please take it home and put it in your trash can. This includes places like the beach, riverside and water bodies. Learn more about waste disposal here.

Use water wisely. Do not keep the tap running when not in use. Also, you can reduce the amount of water you use in washing and bathing. If we all do this, we can significantly prevent water shortages and reduces the amount of dirty water that needs treatment. Read more
