Regular City Council Meeting January 12 , 2004 Page 10 Freese and Nichols studied each component of the Water Treatment Plant and found a problem in the sedimentation basins. Mr. Mussullam stated the plant was rated at 32.3 MGD but the reliable capacity of the sedimentation basins is really about 20 MGD. He said when the sedimentation basins were designed the effluent quality was at 1.0 NTU and is now less than 0.3 NTU which indicates a need for bigger sedimentation basins. He related that the plant’s filtration is at 31.1 MGD which is much higher than its rated capacity. They projected about 28,800 residential water customers in 2025 with about 12,300 connections. Mr. Mussullam indicated the contract with Lamar County Water Supply promises them up to 5 MGD. The study projected 25,000 population served with about 10,000 connections in the county, excluding the City of Paris. He stated that industrial customers, which includes Campbell’s Soup, Kimberly- Clark and Tenaska, and Lamar Power Partners, accounted for 50% of the total production of the water treatment plant. Mr. Mussullam said this means the plant is producing enough water for a 50,000 or 60,000 population. In looking at the Water Treatment Plant demand analysis, Mr. Mussullam said what is important is population projections, historical use of the customers, the number of connections (because the TCEQ regulates the treatment plant capacity based on the number of connections, which is .6 G per minute per connection), contractual obligations, industrial and wholesale, which means that the Water Treatment Plant should be capable of meeting the worse case scenario water demand. Taking all that into consideration, the study came up with a 32.3 MGD for 2025. Mussullam cited a TCEQ ruling that when a plant has reached 85% of its capacity, it has to start planning for expansion. That would be when the plant reached 27.4 MGD which would be in about 2010. However, he reminded them that the reliable capacity was only 20.0 MGD, so something needs to be done to bring the capacity up to the projected MGD.
