ABSTRACT This project is used to prevent the problem occurring in the manual interaction system that is wastage of water tank overflow and absence of water inside the tank. Through this setup automation process is achieved by the help of solenoid valve which is controlled through a micro controller program. It indicates the both high and low level of the water level in the tank. According to the level it initiate the 3HP sub mersible motor to fill the tank and stops when the higher level is reached. Water level management approach would help in reducing the power consumption and as well as water over flow.

Manual work has to be performed in existing method. But this system cannot able to identify the low level, high level of water in the tank. Due to this overflow of water occurs sometimes. No proper management. This causes wastage of water, power and time.

ADVANTAGE OF PROPOSED METHOD Water , one of the great natural resources should be utilized in proper form. But a huge amount of water is being wasted during daily life due to lack of control. Our proposed system guarantees to accumulate a good amount of usable water every day. This monitoring and controlling system used daily life. Due to the fact of controlling conductivity probes. This project introduced a useful wiring automated controlling system. ADVANTAGE OF PROPOSED METHOD It gives the automatic process It will decrease wastage of power, water and time consumption Continuous water supply for daily usage

ALGORITHM 1.Start the program. 2.check the condition If all the 3 tanks are filled motor is in OFF condition Else the motor goes to ON condition 3.If motor is in ON condition check the following If one tank is empty the solenoid valve is open Else the solenoid valve close 4.Repeat the process 5.Stop the programs

HARDWARE KIT

FUTURE WORK Even though there are many advancements in the water level controlling system. The project deals with the implementation of controlling the water level in multiple tanks with a single motor with proper priority issues the solenoid valves. This can be further developed by implementing wireless protocol for the controlling parts so that the wiring cost can be a reliable one.

CONCLUSION Water is one of the most important basic needs for all living beings. But unfortunately a huge amount of water is being wasted by uncontrolled use. Some other automated water level controlling system is also offered so far but most of the method has some shortness in practice. We tried to overcome these problems and implemented and efficient automated water level monitoring and controlling system. Our intension of this work was to establish a flexible, economical and easy configurable system which can solve our water losing problem. We have been used a low cost PIC 16F877A microcontroller in this system.
