Council Member The only changes that have been made to our system are as follows: We installed new chlorine and PH analyzers that use less process water. Our filter washes have been cut in half due to filter media rejuvenation and filter studies performed by an outside contractor.

Type of treatment plant: Page 1 of 3 Version 3/2014 NPDES PERMIT APPLICATION - SHORT FORM C - WTP For discharges associated with water treatment plants ® Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by filtration and disinfection) ❑ Ion Exchange (Sodium Cycle Cationic ion exchange) O Green Sand Filter(No sodium recharge) ❑ Membrane Technology (RO, nanofiltration) Check here if the treatment process also uses a water softener ❑ 6. Description of source water(s) (i.e. groundwater, surface water) Surface Water (Ivy River) 7. Describe the treatment process(es) for the raw water. Raw water is injected with Delpac 2020 (Aluminum Chloride Hydroxide Sulfate) and 12.5% caustic (Sodium Hydroxide) before reaching our up-flow clarifier. Then it is injected again at the start of our conventional treatment process at the flash mixer. Water then runs through settling basins to dual media filters. At this point chlorine gas is injected for disinfection. Once filtered we adjust PH with caustic and add a corrosion inhibitor (phosphate) then to our storage tank to be pumped to town. 8. Describe the wastewater and the treatment process(es) for wastewater generated by the facility: Our 250,000 gal waste basin receives all of our process water and backwash water, this water is injected with S02 (Sulfur Dioxide) to remove chlorine residual just before it enters the waste basin. We also empty our settling basins into the waste basin biannually. The clarified water is decanted to the designated stream and all sludge is pumped from the waste basin into a tanker and hauled to MSD in Buncombe County. 9. Number of separate discharge points: 1 Outfall Identification number(s) 001 10. Frequency of discharge: Continuous 0 Intermittent If intermittent: Days per week discharge occurs: 6 Duration: length of plant run after settled 11.

Sprinkle Jr. Water Treatment Facility Waste Water Sludge Management Plan The Lawrence T. Sprinkle Jr. Water Treatment Facility is a 1.5 MGD municipal water treatment facility. The facility incorporates the use of an up-flow clarifier for pre-treatment of surface water. After clarifier treatment process is conventional in design. We have a 250,000 gal waste clarification basin for process and backwash water collection and clarification. Clarified waste water is decanted via use of joined pipe with winch depth control. Decant of waste waters are controlled by the following procedures. Waste waters collected in waste basin are allowed to settle to acceptable limits set forth in NPDES permit#0085154 requirements. Settled water meeting NPDES requirements are periodically removed by use of winch controlled decant pipe. Sludge generated in process is pumped (as needed) by vertical turbine pump into a licensed waste tanker and hauled to MSD of Buncombe County for disposal. Disposal is in accordance with North Carolina General Statues regulating waste disposal. Daily average effluent is calculated by totaling all filter wash waters, calculated process sample pump totals and basin volume if drained for cleaning. Typically the effluent is estimated over a 7 day period. No effluent metering device is in play ��2�i Jared T. Duncan, ORC Lawrence T.
