Water
Usage Guide In determining water consumption of any application, it is more desirable to obtain the actual water meter history. Generally, a six month history will be representative of the applications requirements. This can easily be accomplished by contacting the water service supplying the application. Such requests are considered public information. Many of these services record usage in cubic feet. To convert volume given in cubic feet to gallons, multiple by 7.5. Example: 50 cubic feet x 7.5 = 375 gallons. Another procedure in determining consumption, and in particular when a meter reading is not available such as on a well system, is the use of a clock recording method. Upon determining the GPM rating of a well pump, connect an inexpensive clock to the pump circuit. Set at 12:00 o’clock and record daily the number of minutes the pump ran. Multiply these minutes recorded by the GPM rate and the average total daily consumption can then be estimated more realistically. A third method that can lend credibility to an estimated daily usage is through comparison. By obtaining an actual meter recording usage of a similar operation, the customer will have more confidence in your projections. When it is not practical to utilize any of the methods thus far described, the estimating of usage can be achieved by the chart below.
