WINTERGREEN WASTEWATER TREATMENT PLANT REPLACEMENT PROJECT
Eight years ago planning began for the replacement of the Wintergreen Wastewater Treatment Plant along with a comprehensive Inflow & Infiltration Study. The purpose of this project is to replace the worn-out package plant that has served the Wintergreen community very well since 1973 and to increase the level of treatment to achieve compliance with the reduced Ammonia permit limit as well as be proactive with the Chesapeake Bay Protection Program.The Wintergreen WWTP is facing a Voluntary Consent Order with the Virginia Department of Environmental Quality due to failed plant performances in meeting changing regulations. The circumstances for the Voluntary Consent Order is because of our proactive planning five years ago. A Voluntary Consent Order bypasses the Notice of Violation and associated penalties but still maintains all other aspects of a Consent Order. The estimated cost for the Collection System improvements and the Wastewater Treatment Plant replacement is $18,538,561.

SCHUYLER WASTEWATER TREATMENT PLANT PROJECT
The aged Schuyler Wastewater Treatment Plant is facing a Consent Order issued by the Virginia Department of Environmental Quality to address significant Inflow & Infiltration and effluent permit exceedances. The collection system and the antiquated wastewater treatment facility is in need of a total replacement. The Preliminary Engineering Report is complete. This facility serves 44 customers and we are also looking into replacing the sewer collection system installing a sewage pumping station and replacing the wastewater treatment facility. USDA-Rural Development is funding this $5,202,700 project.

LOVINGSTON SEWER SYSTEM
AT THE FORMATION OF THE NELSON COUNTY SERVICE AUTHORITY (NCSA) IN 1988 THE COUNTY OWNED AND OPERATED THE LOVINGSTON SANITARY DISTRICT. THIS SYSTEM WAS TRANSFERRED TO THE NEWLY FORMED NCSA. THIS CONVOLUTED MAZE OF A SEWAGE COLLECTION SYSTEM BROUGHT WITH IT MANY CHALLENGES AND PROBLEMS. WE ARE NOW FACED WITH THE RESPONSBILITY OF EITHER REPLACING THE SANITARY SYSTEM OR RELINING THE EXISTING UNDERGROUND PIPES, WHICH IS LESS INVASIVE.
THIS PROJECT WILL ENCOMPASS THE 16,000 LINEAR FEET OF SEWER MAIN AND APPROXIMATELY 100 SANITARY SEWER MANHOLES. THIS PROJECT CAN NO LONGER BE AVOIDED. OVER 8,000 LINEAR FEET OF SEWER MAIN AND 41 MANHOLES ARE IDENTIFIED AS HAVING SEVERE PROBLEMS OF OVERFLOWING DUE TO ROOT INTRUSION AND FAILING OLD CLAY PIPES. THE REPLACEMENT OPTION IS ESTIMATED TO COST AS MUCH AS $4,000,000.

BLACK CREEK RESERVOIR DREDGING
THE BLACK CREEK RESERVOIR WAS COMPLETED IN 2004. OVER THE PAST 19 YEARS OVER 7 1/2 FEET OF UPSTREAM SEDIMENT HAS SETTLED IN OUR RESERVOIR. THIS BUILD UP CAUSES BOTH REDUCTION IN THE VOLUME OF RAW WATER STORAGE AS WELL AS CHANGING THE WATER CHARACTERISTICS, WHICH MAKES TREATMENT MORE DIFFICULT. THE NELSON COUNTY SERVICE AUTHORITY (NCSA) IS IN THE PROCESS OF OBTAINING BIDS ON MOVING FORWARD WITH HAVING THE BLACK CREEK RESERVOIR DREDGED, WHICH WOULD OPEN UP THE INLET TO ALLOW UNRESTRICTED FLOW FROM BLACK CREEK INTO THE RESERVOIR. THE DREDGING IS ESTIMATED TO COST AS MUCH AS $2,000,000.
