Water Saver
Motivations
The severe drought in California and the dramatic decrease of Lake Chad inspired us to create an affordable water saver system.

We want the system to be so simple that any one can use it to know when their soil needs more or less water and prevent uncontrolled water usage.

Our academic motivation is to incorporating ICT (Information and Communication Technology) into water saving and irrigation control system.
Water Saver2.0
The Water Saver is composed of 3 layers:

Sensing Layer: Sensors (temperature and humidity), location system and weather radars collect information about the environment and send it to the middle layer for processing.

Java Agent Layer: A smart agent (JMX Agent) in the middle layer calculates average of readings in intervals and makes decisions based on configurable parameters thresholds.

Presentation Layer: A multi-screen presentation and control layer is provided to configure the system and give user the control on water usage manually or automatically.

Problem
Jan 17 2014, Governor Jerry Brown announced the worst California’s drought in 100 years.
By 2007 Lake Chad has shrunken more than 80% of it's size which deeply impacted people around the Lake.

Goals
Control water usage, save money, plants and the environment.

Provide public authorities, population, and NGO with affordable tools to manage the use of limited resources .

Build an easy to install, easy to use, open, extensible software solution that meet varieties of social and natural constraints.

Build an application that is accessible from anywhere (home, office, abroad) using any device (Laptop, Tablet, Phone).
Water Saver is built on free and/or open source software packages and libraries.

Conclusion
Software
Out Of Pocket
We built from scratch a simple system with little to no software programming nor with environmental background.

Despite lack of funding for our project we reached most of our goals.

Compared to existing commercial water irrigation control products, Water Saver is open, affordable, simple and easy to use.

Water saver is flexible and can be used for other purposes including soil nutrients control or monitoring of patients vital signs among other things.

Water Saver is a useful tool for a multinational or region wide initiative to control limited resources wastes (water, fertilizer, etc.).
Current Works

Lake Chad Disappearing
California Drought
JAVA
Three Layered Architecture


Lake Chad, a source of freshwater for irrigation in Chad, Niger, Nigeria and Cameroon in Africa has been rapidly vanishing:

Satellite images show dramatic decrease in size of the lake over 30 years

Experts says that if nothing is done, the lake will completely disappear in less than 20 years

Since 1963, it shrunk to nearly twentieth of its original size (80% lost)

This is due both to climatic changes and high demands irrigation water



The current water situation in California is gradually worsening and the governor encouraged people to reduce their water use by 20% this year.

The drought is set to affect California's agricultural industry. It is estimated that California could lose 5 billion dollars in agricultural profit.

Some rural communities are in danger of losing their water supply within 120 days.

User Interfaces

Why is Water Saver an Innovation?

Water Saver is Open and Flexible (Ease of Integration and Extension)
Not only Water Saver is built on open source software, it remains fully open and can be easily extended by other developers and hobbyist
The fact that it follows standard software architecture and uses clearly defined interfaces, it can be integrated to other any systems

Water saver is generic (Wider Application)
Can be adapted for other purposes with minor changes - for example with the appropriate sensors that collect in real time soil nutrients Water Saver can be used to determine the amount of fertilizer needed for the soil to grow plants
On a totally different sectors - the same proposed architecture can used for remote healthcare (monitoring of patients vital signs) or for home security (remote location surveillance and assets management)

Water Saver has a replicable model (Scalable)

It can be used as a foundation for multinational, regional or national irrigations and water management projects (e.g.: Lake Chad disappearance or California Drought)
It can also be used by NGO and/or farmers in rural areas to optimize the use of limited and/or disputed resources (water, fertilizer, seeds, etc.) on a larger scale.
Why is Water Saver an Innovation?
Water Saver is Affordable (Low cost)
The Water Saver core components costs $54.00 out of pocket
Typical commercial irrigation systems cost at least $300.00 US add to that installment and maintenance fees.

Water Saver is Easy to Use (Simplicity)
Does not require professional installment or irrigation system maintenance
Self adjustment of water and temperature levels
Can be easily adopted by a non technical person

Water Saver is accessible from Anywhere at Anytime (Extended Reach)
Accessible from home (personal wi-fi), office (intranet), abroad (web)
HTML to HTML5 client can be accessible from any device (Laptop, Tablet, Regular phone as well as Smart Phone).

Water Saver is 100% Developed in Java (Develop Once & Run Anywhere)
Existing embedded water management using Raspberry pi are built with Python
Water Saver is the first water saving system built no Embedded expertise.
It was fully developed in standard Java (not Embedded) and tested it on many platforms with no code changes (PC, Mac, Linux and other embedded devices)
