Five 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 Enhanced Nutrient Removal of Nitrogen, Phosphorus and Ammonia 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 $20,100,000.
WINTERGREEN 11TH GREEN/FAIRWAY MAIN INSTALLATION PROJECT
This project is to replace the existing 8" sewage force main coming from the Fox Grape sewage pumping station and the 6" well line coming from No. 12 and No. 13 wells. The proposed project is to install the two new mains alongside the 11th green/fairway eliminating the existing parallel mains that are located in the Devils Bend subdivision under Wintergreen Drive. The aged infrastructure will be abandoned in place.
It is estimated this project will cost between $300,000 to $350,000. Preparation is currently under way to begin this project November 1, 2019 and to finish by March 31, 2020.
GLADSTONE SEWAGE TREATMENT PLANT
The Virginia Department of Environmental Quality has requested a Plan of Action, which will include the necessary steps and prompt schedule of implementation for controlling anticipated problems resulting from high flows. The STP has a design permitted flow of 6,200 per day discharge, which is being exceeded.
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 near completion but at present the estimated cost to replace the WWTP facility is $3,000,000. This facility serves 44 customers and we are also looking into providing each of these sewer customers with a septic system, which will allow us to do away with the WWTP. The estimated cost for individual septic tanks and drain fields for each customer, which will also require soil analysis and engineering total $1-$1.3 million.
