Quality drinking water distribution system

Abstract

Drinking, cooking, and many other activities need the use of water on a daily basis; however, a large amount of water is lost in many enterprises and public utilities. In light of this, we came up with a plan to cut down on waste. Our goal is to automate water delivery, detect theft, avoid waste, and determine the pH and TDS values of water using a PLC-controlled system. The water level can be determined by utilizing a laser light based liquid level Sensor. The leakage can be detected by verifying the initial flow rate and final flow rate. The water must be a drinkable, the purity of the water is attained by controlling hydrogen ion concentration and conductivity of the water. Hydrogen's potential ranges from 0 to 14. The drinkable water pH is ranges approximately from 6.8 to 8.4, the potentiometric pH meter can be used to determine the water's pH value. Measurement of Total Dissolved Solids (TDS) is used to determine whether water is acceptable for human consumption in order to avoid contamination. Drinking water should be in the range of TDS of 75 to 90†ppm. The TDS and pH values are varies with respect to temperature so that the temperature also be considered for the measurement.
