Technology can bring

relief in a number of

areas: urban water

systems, water for

agriculture, wastewater

treatment, water

use in industry and

more. Technology

has leapfrogged: Big

Data and the Internet

of Things (IoT) are

making possible

collation of immense

amounts of data and

information and has

reduced decision-

making in Water

Management in

real-time

Agriculture – where 70% of the world’s water goes

Water for agriculture can be supplied sufficiently if we implement

smart technologies. In Israel more than 50% of water for irrigation

comes from treated sewage water. Drip Irrigation technology has

changed the face of irrigation for agriculture, saving between 20%

and 50% on water consumption,and is spreading quickly worldwide.

A number of companies are bringing hi-tech expertise – in algorithms,

sensors, measurement and control – to agriculture. One company

has developed a system which samples and monitors, in real-time,

the chemical and physical changes in the root zone. Using fuzzy-

control algorithms,the system automatically activates irrigation and

fertilization,saving 50% on water consumption benefiting dairy and

fish farms as well.

Our cities are ‘leaking’

Large desalination and water purification, while being especially in

countries like Israel where there is an inherent lack of fresh water,

have helped but we need to control the wastage of fresh water

through inefficient municipal water systems.Non-RevenueWater (or

NRW) is lost through leaky pipes,inaccurate measurement and theft.

Innovative technology has helped‘see’what is going on in the pipes

under our city sidewalks. Today we can manage pressure on the

pipes and lengthen their shelf-life.

For municipalities that lack monitoring capabilities,another company

offers easy to use “water kits” with sensors that monitor the water

flow, and yet another uses satellite imagery to detect leaks,with no

need for any infrastructure implements on the ground.

Successful water loss reduction programs have been implemented in

various places in the world.An ambitious project in Jamshedpur,India

by the private utility Jamshedpur Utilities and Services Company,was

able to lower water loss froman estimated 36% in 2005 to 10% in 2009.

Water quality is equally important.A young Israeli startup is marketing

a unique straw like electronic device which can be dipped in water

to get a reading on water quality within seconds.  The device costs

only $50 and is reusable.

Taking the“waste”out of wastewater

The modern world’s industrial activity has created a major challenge

for humanity – wastewater. One prime example of the dangers of

wastewater is River Ganges. This sacred river, which provides over

25% of India’s total water resources,has been so polluted by industrial

and human waste that in some parts the levels of bacteria are 120

times greater than what is considered to be safe levels for bathing.

The current government in India is placing heavy emphasis on the

herculean task of cleaning up River Ganges. The World Bank has

committed $1 Billion to the project, called the ‘Ganges Action Plan’,

and Israel – led by the efforts of Israel NewTech - is working closely

with India’s Ministry ofWater Resources,River Development & Ganga

Rejuvenation to bring advanced Israeli wastewater purification

technologies to the project.

Israel is recognized not only for the amount of treated wastewater

it produces, but for the quality of the water as well. Mekorot’s Dan

Wastewater Treatment Plant was recognized by the United Nations

as one of 30 leading global projects that demonstrate the ability of

government projects to confront environmental challenges.The plant’s

unique method uses the natural filtration qualities of sand in order

to improve the quality of sewage.After wastewater is purified in an

ordinary facility,it is recharged into the ground,where it undergoes

an additional, natural filtration making it suitable for irrigation.

Breakthrough technology innovations mean that wastewater treatment

doesn’t necessarily have to depend on large, expensive plants.One

inexpensive solution is a modular Spiral Aerobic Biofilm Reactor

(SABRE).The breathable membrane enables 90% savings in energy,
