End User: West Virginia Department of Natural Resources

Location: Tygart Lake State Park, WV

Capacity: 20,000 GPD

System Commissioned: July 2021

BACKGROUND

When the existing package plant at Tygart Lake State Park began to fail, the WV Department of Natural Resources (DNR) turned to EPC LTD for a reliable solution. With peak season approaching, they needed fast implementation, regulatory compliance, and peace of mind

Issue

• Failing system exceeding discharge permit limits

• Strong odors disturbing nearby overnight cabins

• High maintenance demands on park staff

• Seasonal flow changes requiring a stable, adaptable solution

  
  

The Challenge

• Tight schedule before high season starts

• Manpower shortage for operation

• Nearby guests cabins required a low-noise, odor-free system

• Finding a cost-effective solution that wouldn’t require high maintenance

• Park needed a system that could handle large hydraulic fluctuations due to Inflow & Infiltration (I&I)

The EPC Solution

EPC installed a Bio-Disk® package plant, a modular, plug-and-play system designed to perform reliably in remote or variable conditions.

System Highlights:

• Natural aerobic biological treatment (Rotating Biological Contactor)

• UV disinfection eliminates harmful chemicals — no chlorine needed

• Quiet operation and small footprint, ideal for parks and eco-sensitive sites

• Scalable design built to accommodate park development

• High resilience to I&I fluctuations is a core advantage of fixed-bed treatment

The Results

• Full compliance with EPA discharge limits

• Odor and noise issues resolved

• Minimal OPEX and staff workload

• Consistent, low-maintenance performance since 2021
