Question 1

What is the overall revenue from the sale of water less the operating expense for 1

month (30 days) from the following problem?

The average gpcd for a town of 12,000 people was calculated out to be 175. The

overall efficiency of the wellâ€™s pump and motor is 70% and the kW-Hr rate for

electricity is $0.10. The well has a pumping level of 58 feet with a drawdown of 20

feet and is pumping against a constant head pressure of 125 psi. Last year the annual

maintenance expense for the well was $5,500. The well is also equipped with a

chlorinator that doses the well to 1.5 ppm. The 65% calcium hypochlorite costs $1.68

per pound. The consumer cost for one unit of water (CCF) is $0.85. (Assume the

well is operating 24 hours per day)

Thanks in advance
