INTRODUCTION
A water meter is a device that is used to measure the volume of water usage.
A prepaid water control circuit system is a control mechanism that allows water usage when there is a certain amount of prepaid units in the control circuit system and terminates water usage when the units are over.
In such a system, a customer purchases a separate prepaid credit card with values of credit units encoded in it.
The units are loaded into the control circuit system which allows water usage, when the units are over the control circuit system cuts off water automatically until recharged with new units.
PROBLEM STATEMENT
The current water metering system is postpaid.
Water authority sends its workers to customer’s locations to read water meter units.
The system is time consuming to the DAWASCO workers.
The system does not give accountability to costumers.
PROJECT OBJECTIVE
General objective
The general objective of this project is to design a prepaid water control circuit system for water metering.
Specific objective
To design an electrically controlled valve that will be used to open and close water flow to the customer.
To design sensing system that will generate voltage equivalent to the amount of water used by a customer.
SIGNIFICANCE OF THE PROJECT
To reduce or eliminate the expenses of reading meters at the customer’s locations.
To eliminate the bad habit of some customers who load up their bill debts.
To eliminate the expenses incurred by the water authority to cut meters of customers who fail to pay their bills for a long time.
