PROBLEM STATEMENT:

Water issues in developing countries include scarcity of drinking water, floods, the siltation of river systems, as well as the contamination of rivers and large dams. Some 1.1 billion people in developing countries have inadequate access to clean water. Millions of people spend hours every day collecting water, 2.6 billion lack access to sanitation, and 1.8 million children die each year from diarrhea.

Humanity demands a need for freshwater for agricultural, industrial, and commercial processes. With rising demand, the quality and supply of water diminishes. To address this challenge, organizations focus on increasing the supply of freshwater, mitigating its demand, and enabling reuse and recycling.

Approximately 71% of illness in developing countries are caused by poor water and sanitation conditions.

DESIGN IDEA:

Water is the most consumed thing in our planet. Now, due to pollution, it is difficult to find good drinking water for daily usage. Water level is also reducing year by year and we have to utilize water in a good manner, by reducing the pollution and monitor water wastage.

Considering the problems, we have planned to monitor the water wastage by using sensors for reuse of water, thereby helping to reduce water wastage.

We have also planned to monitor the rate of contamination in water like acid(pH) level, purity of water to check whether the water is suitable for drinking or not.

Ionic toxics has also caused lots of diseases which will affect the future. So, we also monitor the ionic concentrations in water using Conductivity sensors, thus helping to know the ionic contents and to help in purification of water for future use.

WORKING:

pH sensor:

pH, commonly used for water measurements, is a measure of acidity and alkalinity, or the caustic and base present in a given solution. It is generally expressed with a numeric scale ranging from 0-14. The value 7 represents neutrality. The numbers on the scale increase with increasing alkalinity, while the numbers on the scale decrease with increasing acidity. Each unit of change represents a tenfold change in acidity or alkalinity.

Any solution is like a small battery. It can generate voltage depending on Hydrogen ion (H+) concentration. Acidic solution has more Hydrogen ion concentration than alkaline solution.

pH probes measure pH by measuring the voltage or potential difference of the solution in which it is dipped. By measuring potential difference, hydrogen ion concentration can be calculated using the Nernst equation which gives the relationship between Hydrogen ion concentration and Voltage or Potential.

ORP Sensor:

ORP sensors measure the Oxygen-Reduction Potential of a solution. Used in tandem with a pH sensor, the ORP measurement provides insight into the level of oxidation/reduction reactions occurring in the solution.The ORP Sensor requires a compatible interface and software to collect data.

Turbidity Sensor:

Turbidity sensors measure suspended solids in water, typically by measuring the amount of light transmitted through the water. They are used in river and stream gaging, wastewater and effluent measurement, drinking water treatment process and control, control instrumentation for settling ponds, sediment transport research, and laboratory measurements.

Conductivity Sensor:

Conductivity measurements are carried out in industrial processes primarily to obtain information on total ionic concentrations in aqueous solutions. Widely used applications are water purification, clean in place (CIP)control, and the measurement of concentration levels in solutions. The measuring system consists of an appropriate inline sensor directly inserted or in a housing, a cable connected to a transmitter converting the received signals to a measurement result or forwarding it to a DCS.

Submersible Waste Water Level Sensor:

Measure the level of leachate in above ground tanks on landfill sites. Leachate is the liquid that has drained from a land-fill site which consists of rainwater mixed with harmful substances from the breakdown of landfill waste. Leachate must be prevented from escaping into the surrounding groundwater and therefore it is extracted from the landfill and stored in tanks where it is eventually transported away for treatment.

The Data Collected from these sensors are processed using a specific controller and are uploaded to the cloud with the help of IoT where the respective departments can observe and take corrective measures.

APPLICATIONS:

This project has application in both domestic and industries. This project will help us to save water and help us to provide a better future.

WE WANT OUR PROJECT TO WIN BECAUSE WE WANT TO SAVE OUR MOTHER EARTH FROM POLLUTION AND ALSO SAVE OUR ENVIRONMENT, WHICH WILL HELP US AND OUR NEXT GENERATIONS TO HAVE A BETTER FUTURE. THIS PROJECT WILL HELP US TO MONITOR THE WATER WASTAGE AND ALSO THE POLLUTION LEVEL IN WATER, WHICH WILL REDUCE THE DISEASES CAUSED DUE TO POLLUTION AND ALSO HELPS TO RE-USE WATER BY MONITORING THE WATER WASTAGE SINCE THE WATER LEVEL IS DECREASING YEAR BY YEAR.

THIS IS THR MAIN AIM OF OUR PROJECT TO REDUCE WATER WASTAGE AND POLLUTION AND TO HAVE A BETTER FUTURE.

Inspiration

The topic was based on social cause. These topics, if implimented very well will definitely help us to provide better future, since water and land pollution has already caused lots of damage to our environment. This actually inspired my team to create some new idea, which will definitely help us to clean or at least help us to maintain good environment, helping everyone to stay healthy and thus help our mother Earth a good place to live.
