PROPOSED POWHATAN POINT WASTEWATER TREATMENT PLANT

The Proposed Powhatan Point Wastewater Treatment Plant (WWTP) Project is to be constructed on the Murray Energy refuse site facing the river next to the Barge Transfer Station.  It is expected to occupy 2 acres (87,500 sqft), as illustrated below.

It is expected to be designed based on the plans and specifications used for the Dallas, Georgia Pumpkinvine Creek Water Pollution Control Plant by the Edison Engineering Group, Inc. (plant construction completed in 2015). The site serves the initial requirement of 1.5 million gallons per day (MGD), but will be constructed to support expansion to meet up to a 3 MGD future demand.

Project Scope

Development shall make the Proposed Powhatan Point Wastewater Treatment Plant (WTP) Project capable of meeting 1.5 MPD receiving capacity and efficiently processing that wastewater to satisfy effluent discharge limits, Total Nitrogen, and Total Phosphorous goals. A plan view layout of the WTP is provided in Figure 2, illustrating the initial design and proposed upgrades and other areas requiring evaluation or improvement. The numbering used below corresponds to also the later expansion elements.

 

The following summarizes the general scope of the project:

1.  Oxidation Ditch Aeration Basins (parallel WesTech OxyStreamTM Oxidation Ditch).

2.  Secondary Clarifier

3.  Tertiary Filter Unit

4.  Digester

5.  Dewatering building to include a belt press and the covered roll-off area to allow for sludge box unit and a directional flow chute for depositing solids into the sludge boxes.

6.  Installation of a blower unit.

7.  Installation of pumps at influent pump station and the lift station, including the installation of individual flow meters equipped with SCADA telemetry.

8.  UV disinfection unit.

9.  RAS/WAS pumps

10.  Instrumentation within the MCC.

11.  Reuse water pump station.

12.  Odor Control for the headworks.

13.  Headworks to accommodate max day flows and address the need for equalization to balance flows from the two influent lift stations.

14.  Generator capability (under load)

15.   Reuse water system for dependency and maintenance isolation, as well as, a dedicated line to the dewatering facility (belt presses).

16.  Drying beds and construction of a utility/workshop building (40’ x 80’) equipped with three roll-up doors and sufficient area for parking a full-sized pickup truck and two facility ATV’s.

17.  Dump station equipped with two (10’x10’) sand beds which drain to the septage batch tank. A sloped receiving floor (with high splash walls) capable of accommodating 20,000 gallons of truck delivered pumped wastewater shall be collocated.

 

Additional items provide: (a) road construction to the plant from the Murray Energy transfer station access to Route 7; (b) WTP site prep and elevation above flood plan; and (c) new sewer line connection to the WTP and modification/improvement of existing lines to realign to the WTP.
