II. Description of Facilities A. Collection System- System Services Division
The MSD service area covers approximately 180 square miles. The MSD provides service to areas along the French Broad River Valley and the Swannanoa River Valley as far as Ridgecrest. There are over 960 miles of public sanitary sewer line, 31 public pump stations within the collection system and approximately 26,800 manholes system wide. Less than 65 miles are large interceptors with diameters ranging from 24" to 66". One third of the balance is small 6" lines and two-thirds are medium size lines ranging from 8" up to 24". Most of this pipe is between 50 and 100 years old, and is in dire need of rehabilitation or replacement. The District’s 49,000 customers reflect a service population of an estimated 135,000 people. In FY 2009, about 28% of the water treated at the Districts Wastewater Reclamation Facility was Infiltration (groundwater seeping in from cracks in pipes and manholes), and Inflow (rainwater entering through manhole lids and unauthorized Storm Water connections). The District has been aggressively working to abate this problem.
B. Wastewater Reclamation Facility (WRF)
The present Wastewater Reclamation Facility (WFR) is a 40MGD secondary treatment plant serving Buncombe County (specifically Asheville, Biltmore Forest, Black Mountain, Montreat, Weaverville, Woodfin and Buncombe County at large). Overall, the MSD services approximately 49,000 separate sewer customers, a combined customer population of 135,000, and over 20 separately billed industries. In 2009 the facility treated an average daily flow of 16.5 million gallons per day. The WRF is an attached growth design, comprised of 152 rotating biological contactors (RBC’s), which provide full secondary treatment. These RBC’s provide 450-500 acres (3+ acres each unit) of surface area for biological growth. It has been said that MSD’s facility is the largest RBC plant in the world. The plant consists of: Preliminary Treatment Components • IDI Barscreens (2 units) w/screenings compactor and shaftless screw conveyer • Influent Pumps (3 units) – 35 MGD rated capacity each • Aerated Grit Chambers (3 units) w/associated grease removal Primary Treatment Components • Primary Microscreens (7 units) – 250 micron screens Secondary Treatment Components • 1st Stage RBC’s (44 units) • 2nd Stage RBC’s (72 units) • 3rd Stage RBC’s ( 36 units) • Intermediate Pumps (3 units) – pump water to clarifier from 3rd RBC stage • Intermediate Clarifier (4 cells – total volume 2 MG) • Secondary Microscreens (18 units) – 27 micron screens Disinfection Components • Sodium Hypochlorite solution – average feed 1000 gallons/day at 8% solution strength with dechlorination of effluent prior to exiting the treatment facility Residuals Handling Components • Gravity Thickeners (2 units) – 100 foot diameter each • Gravity Belt Thickeners (4 units) • 2.5 Meter Belt Presses (2 units) • Anaerobic Digesters (2 units) – 100 foot diameter each • Fluidized Bed Incinerator (40DT/day rated) • Alkaline Stabilization Facility (40DT/day rated) Energy Management Components • 2 Megawatt Diesel Generator (full back-up/emergency power for WWTP) • 450 Kilowatt Gas Generators (2 units) – operate on natural, digester or landfill gas • 850 Kilowatt Hydro Turbines (3 units) – induction units (French Broad River source) Automation Components • Foxboro Distributed Control System (DCS) – full automated control of WWTP Sludge Management Plan • MSD utilizes its fluidized bed incinerator as its primary residual management option, with alkaline stabilization as a secondary management option – as well as maintains an arrangement with the Buncombe County landfill (lined) for emergencies. Presently the facility is managing 12-15 DT’s per day of residuals. The facilities are designed for 40DT’s per day. Due to the lack of true primary clarifiers, most of the sludge generated at the facility is secondary in nature (i.e. sloughings from the RBC’s). Sludge is thickened in on-site gravity thickeners to a consistency of 4-7% solids at which time it is then pumped to the 2 1/2-meter belt presses. These units dewater the sludge to over 24%
solids and then it is pumped to the incinerator. The facility maintains gravity belt thickeners and anaerobic digesters; however these units are presently not being utilized. Air emissions from the incinerator are of excellent quality. Recent air emissions testing place removal efficiency of the air scrubbers at 99+% for regulated parameters. Incinerator ash is thickened on-site via a gravity ash thickener and then pumped to an on-site lagoon. Groundwater is monitored in accordance with NCDENR requirements (up & down gradient). When alkaline stabilization operations are activated, a class A product is produced and distributed to the public. The alkaline add-mixtures utilized in the process are fly ash, cement kiln dust (CKD) and lime kiln dust (LKD). The process incorporates the use of the "N-Viro" process when these alkaline products are utilized in accordance with the patented mix recipe. Due to the fact that the incinerator operations provide much more cost-effective management, it is utilized as the primary option. Supplementary fuel of natural gas is required due to the 24% solids content. However, reclaimed methane gas from a closed county landfill can be utilized for partial operations. MSD also maintains an "agreement" with the local county landfill (lined) to dispose of dewatered sludge during emergency and/or maintenance/breakdown instances; this provides a 3rd residuals management alternative.
III. Improvements to Facilities A. Collection System Improvements
MSD assumed ownership and maintenance of the various local public collection systems in 1990, and since that time MSD has undertaken an aggressive program to correct existing known collection system problems. Between 1990 and 2009, over 746,000 linear feet of pipe have been replaced and over $204 million has been re-invested in sewer rehabilitation projects. However, due to the large size of the MSD system, there is much work still to be done. From 2009 to 2019, the District expects to rehabilitate or replace an additional 500,000 lineal feet. Approximately $146 million will be spent for the Districts Capital Improvement Program (CIP) over the next 10 years. Of this, 14% will be spent on rehabilitating medium to large interceptors, 72% on rehabilitating or replacing small collection lines, and 12% on the treatment plant and pump station projects. The total estimated cost to rehabilitate the Districts aged collection system and WRF facilities over the next twenty year period is estimated at over $275 million. MSD continues to use its “Pipe Rating” program to evaluate the structural condition of aged sewer lines and prioritize rehabilitation projects. This award winning program accomplishes this through a combination of Closed Circuit Television (CCTV) review, pipe-defect rating, a Geographic Information System (GIS), and engineering analysis. MSD maintains an aggressive Preventative Maintenance Program whereby approximately 920,000 lineal feet of sewer lines were cleaned by high pressure water jetting equipment. In addition, about 164,000 linear feet of sewer lines are mechanically or chemically treated to remove tree roots and blockages. A program to clear MSD Right-of-Ways has been implemented with 40,203 ft cleared this year.
B. Wastewater Reclamation Facility Improvements
Recently completed and upcoming facility rehabilitation includes the following; • • • • Installation of new sludge cake (Schwing) pump & associated controls Installation of 2 new RBC blowers & associated controls Rehabilitation of the Grit and Grease Removal Process Replacement of the aged intermediate pumps. The old pumps are inefficient, hydraulically-driven pumps which use “fluid to pump fluid”. The new pumps will be efficient electrically-driven units, and will save an estimated $72,000 per year in energy costs. Replacement of the final microscreen system. This system has been problematic since its installation, and is scheduled for replacement. The new system will; utilize a microfiltration system, and is expected to be far better performing, and easier to maintain.
•
IV. Performance Measures A. Collection System, System Services Division
• The District has an aggressive Preventative Maintenance program of high pressure cleaning and root control. This year over 1 million lineal feet of pipeline was treated by MSD in this way or approximately 21% of the 960 miles of system. System Services division completed and submitted to NCDNR-DWQ two-six month High Priority Line Inspection Reports and one Increased Inspection and Maintenance Report as required. The High Priority Line report documents inspection of aerial lines, siphons and lines in proximity to vulnerable creeks and streams. The Increased Inspection Report documents oversight of problem sewer lines in the 10 year CIP, all of which must be inspected once every three years until replaced. The collection system recorded 23 sanitary sewer overflows (SSO’s). All SSO’s were remediated according to the District’s standard operating procedures for sanitary sewer overflow cleanup and no severe environmental impact occurred.

B.Wastewater Reclamation Facility (WRF)
Performance measures were successfully achieved during the FY09 annual reporting period. The WRF continues to provide effective/efficient treatment services to the community averaging CBOD & TSS removal efficiencies of 93% and 91% respectively. Flow to the WRF continues to remain well below hydraulic capacity for the plant, with an average flow of 16.5 million gallons per day – the continued combination of the near drought conditions and losses of industrial flows were the main contributors to the reduced flows. The WRF remained in compliance for all permitted parameters and received a favorable review by NC-DENR regional office staff with respect to the annual facility inspections. The regional air quality agency provided MSD with a similar inspection review/report. MSD maintained its service contract agreement with Pace Analytical, Inc. (NC certified lab). This agreement incorporates the exchange of full laboratory testing services for use of the existing laboratory space. This progressive opportunity continues to yield significant long-term savings to MSD. MSD was again recognized for outstanding wastewater treatment efforts by the National Association of Clean Water Agencies (NACWA – formerly AMSA) and received the prestigious NACWA Silver Award signifying consistent NPDES permit compliance during the 2008 calendar year. This marks the ninth consecutive year MSD has been honored with a Peak Performance Award representing continued excellence in environmental protection. The WRF successfully participated in a surveillance audits (both internal & external) regarding ISO14001 certification – coming through with zero (0) non conformances. This program, also referred to as an Environmental Management System, continues to provide significant benefits to MSD both in the short & long-term. Some of the significant divisional accomplishments this fiscal year were:
1. Received the National Association of Clean Water Agencies (NACWA) “Peak Performance Award” acknowledging Treatment Plant compliance 2. Completed replacement of venturi air emission device & heat exchanger improvements 3. Completed design & bidding for intermediate pump replacement CIP project 4.
