Introduction: REAL TIME WATER QUALITY MONITORING AND SUPPLY SYSTEM IN IoT ENVIRONMENT

Abstract--

In urban areas the water supply to residence and commercial establishments are provided at a fixed flow rate. There are incidents of excess water drawing by certain customers/users by connecting motor-pump sets to the water lines which is considered as water theft. In this paper it is proposed to develop an embedded based remote water quality monitoring and theft prevention system by recording the flow rates at the consumer/user end. In order to implement the proposed water supply system, each consumer end should be provided with a web based mobile application consisting of so many options for the user to record the flow rate using a level sensor, water quality sensors and to transmit the same to a remote monitoring station using IOT and it is also provided with an electrically operated solenoid valve to supply water to the consumers. The valve turns on/off by the central processing unit Raspberry Pi to stop the water supply whenever the flow rate exceed a predefined limit. It is proposed to employ a Internet of things for wireless communication so that the information can be passed to many responsible officers cell phone for immediate action.

I. INTRODUCTION

Nowadays drinking water is the most precious and valuable for all the human beings, drinking water utilities faces new challenges in real-time operation. This challenge occurred because of limited water resources growing population, ageing infrastructure etc. Hence therefore there is a need of better methodologies for monitoring the water quality.

With the continuous economic growth, the water demand of enterprises is also increasing. The monitoring of water resource for these enterprises can prevent the occurrence of stealing water and leaking water effectively. Therefore, the monitoring system of urban water supply has aroused extensive attention in recent years. Urban water supply networks form the link between drinking water supply and drinking water consumers. These large-scale networks are vital for the survival of urban life, for maintaining a healthy level of economic development, and for the continuous operation of factories and hospitals.

In world, urban water supply systems are public enterprises, usually part of a local government, and the recent increased interest in privatizing public enterprises has not led to reforms of water systems. Nevertheless, in about 50 cities in the developing world, the water system either has been privatized or franchised to a non-governmental entity for its operation and maintenance.

In this research work it is proposed to develop an embedded based remote water monitoring and theft prevention system by recording the flow rates at the consumer/user end. In order to implement the proposed water supply system, each consumer end should be provided with a web based mobile application consisting of so many options for the user to record the flow rate using a level sensor and to transmit the same to a remote monitoring station using IoT and it is also provided with an electrically operated solenoid valve to supply water to the consumers.

With the rapid development of global system Internet infrastructure and information communication technology in the past few decades has made the communication is reliable for transmitting and receiving information efficiently. So here we used IoT for efficient communication purpose.

In our proposed method, Intel Edision and Raspberry Pi is used as a core controller. The raspberry pi is run on LINUX kernel by the use of keyboard and monitors the LINUX OS is boot on to the Raspberry PI. The temperature sensor, pH sensor can be read directly from the command line. However, this requires us to input a command every time we want to know the sensors reading. In ordered to access all the terminals of the sensors, python program is used.

II. WORKING PRINCIPLE

In this project, it is proposed that the usage of Anti-theft control system for drinking water supply. By implementing this proposed system in a real time; surely it will be able to control the drinking water theft in the domestic areas. In urban areas the water supply to residence and commercial establishments are provided at a fixed flow rate. There are incidents of excess water drawing by certain customers/users by connecting motor-pump sets to the water lines which is considered as water theft.

In this work, it is proposed to develop an embedded based remote water monitoring and theft prevention system by recording the flow rates at the consumer/user end In order to implement the proposed water supply system, each consumer end should be provided with a web based mobile application consisting of so many options for the user to record the flow rate using a level sensor and to transmit the same to a remote monitoring station using IoT and it is also provided with an electrically operated solenoid valve to supply water to the consumers.

The system is provided with an electrically operated solenoid valve to supply water to the consumers. The valve turns on/off by the central processing unit Raspberry Pi to supply the water for a particular time period. The system is provided with an electrically operated solenoid valve to stop the water supply whenever the flow rate exceeds a predefined limit. The processor will switch ON/OFF the solenoid valve using a TRAIC switch. It has been employed a IOT for wireless communication so that the information can be passed among consumer and service provider. And one more important is water is supply to consumer or user only when main tank water is pure. The user can request for the water from main tank through the web site and get the water and he can specify how much amount of time that he need water in the webpage, and he also view the present amount of water bill, and he/she get the water only when the main water from the tank is pure, the purity of water is decided by pH sensor.

III.CONCLUSION

In this paper, the design and development of the real- time monitoring of the water quality parameters and supply system in IoT environment is presented. The proposed system consists of several water quality parameter sensors and purity checking of water and other component for distribution of water, Raspberry PI B+ core controller. These devices are low cost, more efficient and capable of processing, analyzing, sending and viewing the data on cloud and also through WIFI to mobile device. This can implement is suitable for environment monitoring, ecosystem monitoring, etc and the data can be viewed and control anywhere in the world.

Advantages:

1) Economical

2) Portable

3) Low maintenance cost Applications:

• It can be used in Fuel supply system in underground tunnels.

• The concept can be used in electricity management system.
