Water Treatment We recently completed construction of a 30 —inch raw water main from the Stone Quarry on Highway 54 all the way to our water plant in Carrboro. This extends the existing line from Cane Creek, and provides important flexibility and backup protection in case the University Lake supply has to be shut down for maintenance, or in the event of contamination. Major improvements to the water plant were also completed during the past year. We now have the capacity to treat more than 12 million gallons of water a day. Last summer's peak day demand was 10.5. The recent plant expansion incorporates an innovative "upflow clarifier" treatment technology, and now provides two parallel treatment trains that allow us to treat two separate sources — University Lake and Cane Creek — with separate processes, if necessary. Current studies and proposed additional work at the water plant should provide a capacity of 15 MGD. As at the wastewater plant, our water plant continues to satisfy all state and federal water supply standards. And speaking of water supply . . . You may recall during the past Year that OWASA held a series of discussions with the Hillsborough Board of Commissioners about extending the water sales agreement in order to supplement Hillsborough's water supply while they develop an additional source. Those discussions are currently on hold, pending further interest from Hillsborough. Watershed Protection Last month the OWASA Board adopted a comprehensive policy on watershed protection. This statement includes 10 specific elements that the Authority intends to sustain in its watershed management program. One of these is the continuation of a Critical Lands Acquisition Program that was initiated in the current budget. The Board allocated $100,000 for purchasing land in the Cane Creek and University Lake watersheds, and plans to accumulate an additional $100,000 each year for this purpose. 3
