Abstract:

PLC based prepaid purified drinking water station was designed and developed to address the safe distribution of purified drinking water at a reasonable cost to the end users and helped reduce the increasing number of solid wastes brought by used plastic bottles. The design of the machine was in accordance with the standard specifications of a water dispenser. The machine was fabricated using high grade stainless steel and food grade PVC water pipes. The evaluation of the machine underwent several trials to meet the desired volume of water. Dispensing of 250ml purified water will be attained by inserting the validated peso coin to the coin acceptor. The preset time for every transaction is four seconds. Overall dimensions of the machine are 60x52x16 inches equipped with 4 mini water pumps, a controller and four gooseneck faucets. The performance of the machine satisfies the perception of the evaluators. The design was based on the standards of a water vending machine and the desired volume of water to be dispensed was met.
