City Council Water R Sewer Subcommittee Feb. 18, 2003 Page 3 storage tank, four additional pumps, and a meter and they have totally reconditioned those two tanks. Mr. Campbell pointed out the meters for Tenaska III, Lamar County Water Supply, Campbell Soup, one that feeds back to the Water Treatment Plant, one meter that goes to Lake Crook Park, and a meter that go to some homes on Lake Crook Road. Mr. Campbell went back to page three pointing out that if they wanted to put water in those two storage tanks they had to open a little valve called a CV and they actually let water out back down to ground storage for storing water so they could pump it back up. He stated that was not the best way to operate. He said this process was changed in 1994. Now it is pumped at low pressure and to all three of those tanks at ground storage and then, it takes six pumps to pump it to the distribution system. Mr. Campbell advised that they have a total of eight million gallons of storage at ground level. It is then pumped to the two elevated storage tanks. One is a one million gallon tank which is located on 25th NE and the other is a half million gallon storage tank that is on 5th NW. Mr. Campbell advised that there is a two and one -half million gallon elevated storage tank under construction on Bonham Street. Mr. Campbell further explained that in the old days every time people wanted more water all they had to do is turn the pumps up at the Water Treatment Plant. They would pump up and pump down and that is not good for the filters, because every time the flow is increased it surges the filters and lets more dirt come through. At that time, there were more turbidity units allowed by regulations and it was not a real problem. He said when regulations were changed to require a half of a turbidity unit, turbidity became a bigger problem; now it is down to three tenths which is a real problem. A turbidity unit is a measure of the clarity of the water. Mr. Campbell explained that page five has a chart showing the average daily flow. He advised that the bottom line is the billion gallons per year that they pumped and it has been over four billion since 1987. Mr. Johns questioned the seven meters that go to Lamar County Water Supply District. Mr. Campbell said that Lamar has an option to take their water at different points in the system. They pay different prices depending where in the system they take the water that they use. If they take water at the very bottom
