Project Summary

Due to the exponentially growing population and increasing global water demand sustainable water resources and controlled distribution system is a matter of concern. In this project, an IoT Based automated water treatment system to recycle domestic greywater for non-potable use is proposed, along with smart water meter for controlled distribution of water on the basis of per capita. Smart water meter is composed of microcontroller, RF, flow sensor and LCD which is used for communication of real-time metering data to end-user and, water and sanitation authorities (WASA). Sedimentation process followed by a sand filter, pH neutralization, turbidity, and chlorination is included in the greywater treatment system. An Internet of things (IoT) based graphical user interface (GUI) is included for utility monitoring of real-time consumption of water, quality of treated water in terms of pH and turbidity and total treated water which makes the system reliable and efficient than conventional.Data can be used by government authorities for planing of resource management, billing purpose and for study of supply vs demand of water.

Project Objectives

Design and develop sustainable

*Automated water metering system

*Greywater treatment system.

*IoT based GUI for automated monitoring of consumed fresh and treated water along with the quality of treated water.

Project Implementation Method

To date, various methods have been developed and introduced to measure and treat greywater for reuse. In this project, we have designed & developed a system which addresses new challenges in the water sector -including automated billing, treatment of grey water, monitoring the quality of treated water and consumption patterns of users for fresh and treated water. The system provides a study of supply versus consumption of water in order to create awareness to curb water wastage and encourage its conservation. A smart water meter is developed to monitor water consumption in a housing inlet according to the number of persons in a single house along with a treatment system to treat greywater for the non-potable use.

A flow meter measures the fresh water entering in the each House which is shown on LCD and also sent on the internet for further aforementioned purposes.

The treatment system is working in a closed loop by a microcontroller, which takes values from the pH and turbidity sensors, maintained the greywater by adding chemical solutions, if the value exceeds a threshold. The system is working fully automated, if the pH value is acidic then a diluted base is added and vice-versa in a neutralized range of 6.5 to 8.5. Turbidity is maintained if the NTU exceeds a value of 10 then a decoloring agent is added to remove turbidity. Chlorination is done according to the flow rate of greywater.

The data is sent to the IoT and also to SD card of the system, in case of internet instability. Data includes measured fresh and treated water, quality of treated water which includes pH and turbidity of water.

Benefits of the Project

Reducing  the water consumptiom of an average person.

Keep the water resource within a standard.

Increased efficiency in billing,  management, and reuse system.

Saving water through the reuse of grey water.

Reduced overheads on meter reading and billing.

Provides easy maintenance for individuals.

Easy Monitoring of system using daily life gadgets.

Technical Details of Final Deliverable

Smart water meter is composed of microcontroller, RF, flow sensor and LCD. Flowrate can be measured up to 30 liters per minute. The water meter can communicate with the water treatment system remotely within an indoor range of 500m via RF module. It also shows the realtime flow rate of water and total consumed water on LCD.

Sedimentation process followed by a sand filter, chlorination, turbidity, and pH neutralization is included in the greywater treatment system.

pH sensor has an accuracy of +/- 0.1. Water pH is neutralized on a threshold of 6.5 to 8.5 by adding diluted acid or base via pumps automatically.

Drinking Water should have turbidity value of less than 5 NTU and but for non-portable use of water turbidity should be less than 10 NTU so 10 NTU is the threshold for adding a waterdecoloring agent.

Chlorination of water is adjusted according to the flow rate of greywater, by varying the frequency and delay of pump which is responsible for adding chlorine.

Salt produced due to acid and base reaction, and suspended particles in greywater can be extracted from a sloped sedimentation tank.

The treated system can treat up to 750ml/min which can be increased by increasing pressure and flow rate.

Data is monitored and sent not only to the IoT but also in an SD card of a system which helps in case of internet instability. Data includes measured fresh and treated water, quality of treated water which includes pH and turbidity of water.
