Clean Water is a tremendously important part of our lives. It is used for irrigation, cooking, washing, cleaning, drinking, etc. In simple words, Water is Life. Water covers approximately 70% of the Earth's surface, where approximately 97.2% of it is saline, only 2.8% fresh. According to the World Health Organization, the most common diseases linked with poor water quality are cholera, diarrhea, dysentery, hepatitis, typhoid, and polio. As a result, of poor water quality and bad sanitation, an estimated 829,000 people die each year from diarrhea. More than 2,000 children's lives are lost every day. Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules, and larger particles from drinking water. By 2025, half of the world's population will be living in water-stressed areas. we have many methods to make the water clean, pure, drinkable and for use also. But now the only problem is we facing maintaining those systems. RO Plant is one of the efficient methods to clean water but not easy to maintain these plants in remote areas. In some remote areas, either RO plants are not properly functional water quality, TDS (Total Dissolved Mineral) or they are continuously not operational, so we need to monitor them in the real-time so we can fix problems and monitor them collectively in one place. We can monitor and make check the balance of the electricity theft. With the aging of the RO plant system, the equipment run out and they do not perform their function properly due to this reason the level of the PH, and the TDS of the water do not remain suitable that was harmful to drink and there is no check and balance of the RO plant systems. In some areas, the government planted the RO plants in many schools, other government sectors, and different colonies. In most cases, electricity theft is common in areas allotted only for the RO plant. Our project aims to maintain the PH, TDS (Total dissolved solids), and the acidity level of the water that is drinkable and not harmful to the living things, the electricity theft can be controlled and we can also predict and manage the aging of the parts of the RO plant system. And also controls the Water loss and water production using a flow rate sensor. The plant’s power consumption can be calculated using the Potential and Current sensor. And the PH uses a PH sensor and the TDS uses TDS Sensor. Then, these data will be transferred using the Transmitting end which is based on the GSM Module and Arduino. We are collecting the data of more than one plant and the data collected on the receiver end and the comparison graph of Power Consumption, PH, TDS, and Flow rate is displayed on the GUI.
Project ObjectivesProject Objective
- The main outcomes/ objective of this proposed project are as follows.
- Development of multi-purpose RO plant management system.
- The reduction of water loss is due to the aging of the plant.
- Improving water management to reduce risks of water-borne infectious diseases.
- Preventing electricity theft in government sectors.
- Testing the water quality on a live RO plant at a laboratory scale.
- The Hardware implantation in real-time at a laboratory scale.
Project Implementation Method
The implementation of the proposed project will be in the Six steps
At first, we make the Transmitting end and receiving end for the sending and receiving purpose of the message only to the mobile using the GSM module 800L and Microcontroller Arduino UNO.

Figure 7: Receiving end circuit in working condition
Second, I used the PH Sensor with Arduino and check the PH of the dirty water, clean water, and milk the readings are attached below.
Figure 8: PH Sensor using Arduino
Figure 9: Clean Water Figure 10: Dirty Water Figure 11: Milk
Third, I usedthe TDS meter with the Arduino and take the reading of the reading that is attached below.
Figure 12: TDS Meter using Arduino
Figure 13: TDS Reading
Fourth, I used the flow rate sensor with the Arduino the readings were sent to the Arduino and then transmits using the transmitter end, and the taken readings are attached below.
Figure 14: Flow Rate Sensor Figure 15: Flow rate sensor reading
In the fifth step, the current sensor with Arduino measures the value of the current, and the potential sensor measures voltage. By this, we can calculate the Power and then transmit using the transmitter.
In a sixth step, all readings (the TDS, PH, Flow rate, and the Power) values are received at a single receiver and then display on the GUI. Then, I analyze and compare these values with the reference value and in this way, we can make checks and balance the system.
