Re-creating the essential – the future of water

 5 minute read

Can you imagine your day without water? How long can agriculture satisfy demand without water? There is no doubt that water is an essential for life. Globally, the volume of renewable water per capita has declined by 40% in the last 22 years while demand is growing. This article explores the future of water.

Escaping the drought

Global trends like rapid population growth, need for water quality improvements, climate change, and aging, contribute to the growing demand for clean water. Water is vital for economic growth and primary survival. Even though the global water reserve is quite large, only 10% of freshwater is suitable for drinking, agriculture, and industrial use. Water distribution is highly dependent on geography. For example, while the supply of water annually per person in the US is the same as in Switzerland, Miami has a shortage of water, when Minnesota has no troubles satisfying its needs. In fact, in early 2014, there was a peak of exceptional drought in California, and southeastern Brazil was undergoing the worst drought in its history a couple of years ago. The water shortage issue can be addressed from different points, let’s see how to conserve water and to provide better wastewater treatment solutions.

North America and Europe
use about half of this

Water withdrawal is expected to double by 2030 reaching 6,900 km3 worldwide. Currently, 70% of available water is used by agriculture. Africa and Asia utilizing more than 80 percent for agriculture, while North America and Europe spend twice as much. The biggest share of water in the developed economies flows into industrial use. Similar water distribution is to be expected from emerging economies by 2030.

Water usage -

How to lower the demand for agriculture and increase the supply of freshwater? Robotization can be the answer for water conservation in agriculture. Robots and a controlled environment can reduce water usage. “The more mechanized farming becomes, the more urbanites fetishise traditional farming and country living,” says chief executive of the Addington Fund, Ian Bell. “We already see a growing market of wealthy rural incomers willing to pay a premium for craftsmanship and artisanally produced foods. If you can work out how to use tech to minimize overheads while providing services in that area, you can make a lot more money than you will growing lettuce.” The SPREAD vegetable farm – 4,400 m2 warehouse-like robotic farm to be built outside of Tokyo. The farm will be monitored by sensors, data analysis, and satellite mapping providing more efficient water use. Similar projects are becoming more common all around the world. However, the controlled farming environment is mostly located in developed countries, while the biggest water use for agriculture falls on agriculture driven economies in emerging countries. Therefore, more investments should be made to Africa and the Middle East where water shortage is an ongoing issue.

USDA is ready to invest $25 Million in conservation innovation grants. “Conservation Innovation Grants have played a critical role in developing and implementing creative new methods to conserve the nation’s private agricultural lands and strengthening rural communities,” said Agriculture Secretary Tom Vilsack. “Today’s announcement builds on our support of technologies and approaches that help producers increase resiliency to extreme weather such as drought and floods.”

From the other side, the solution might be hiding in eating habits. A change in eating habits towards a vegetarian diet has potential to lower water consumption. Producing one kilogram of meat requires up to 10 times more water than rice or wheat. Water conservation in agriculture has a potential to redistribute available water to other sources. Moreover, lowering livestock will decrease the carbon footprint. According to Rabobank, innovation in food and agriculture is the only way to feed a population of 8 billion people by 2030 and 12 billion by 2100.

Wastewater treatment

Wastewater treatment is starting a new era. The way water travels in urban areas, rural, and manufacturing impacts the whole ecosystem. It is essential to handle wastewater and transform it into a reusable commodity. Innovation platforms for the industry are expanding rapidly. Scientists and startups cooperate closely to provide the best solutions for water purification. One of the examples is a solution by Arivia Technologies. Organics Destruction Cell by Arvia Technology is a tertiary treatment step for the removal of micro-pollutants from wastewater, allowing for water reuse or zero liquid discharge by industrial users, or simply for micro-pollutant-free water effluent. “As a result, the energy used for oxidation is proportional to the amount of organic to be treated, rather than the volume of wastewater. Therefore, the Arvia ODC system is ideal for removal of organic pollutants at low concentrations, including at ppb level.” This innovation can provide a closed water system for industrial use.

The world can witness more and more upgrades of wastewater plants towards a more efficient and sustainable future. The Hamilton wastewater treatment plant in Canada, after a $158 million upgrade can provide up to 56 Olympic-sized swimming pools worth of clean water into the Hamilton harbor every single day. The world’s largest wastewater plant in Chicago pumps sewage into power. According to the Water Environment Research Foundation, wastewater plants are extremely energy demanding. Novel technology of anaerobic digestion when bacteria breaks down wastewater components to form natural gas will make plants energy neutral.

Insight Box

The growing demand on water supply triggers a market for wastewater treatment to expand. At the same time, the chemical industry will increase the headhunting and cooperation to provide the best sustainable solutions for wastewater treatment in urban areas. In developing economies water demand will peak with the development of manufacturing and continuing industrialization Factories will implement a closed water system - to lower water consumption in the industry. Agriculture will move to the controlled environment with the most efficient use of resources and lowered carbon footprint. The water issue is essential in the architecture of future megacities. As the result, plants, cities, farms, will have a closed water system with no water waste at all.

In 2007 global urban population exceeded global rural. This means that over half of the world’s population lives in urban areas and is responsible for over 70% of global greenhouse gas emissions. With the growth of population most of the world is going to be build or rebuild in nearest two decades.
