Facility Plan for the Greater Harrison County PSD
0.60 MGD Wastewater Treatment Plant Upgrades
The Greater Harrison County Public Service District is a large sewer and water service provider throughout all of Harrison County, West Virginia. The District has owned and operated a public wastewater system since 1986. Currently, the District provides sanitary sewer service to 2,081 customers within West Milford, Good Hope, Lost Creek, Laurel Valley, and other areas in the southern portion of Harrison County. The District is in the final design stage of a project that will provide service to an additional 740 customers in the Clarksburg Country Club, Laurel Park and Route 73 areas. The District intends to advertise for bids in spring of 2017.
The District owns and operates a wastewater treatment system located on Highland Dam road in West Milford, West Virginia. The treatment system, to be referred to herein as “West Milford WWTP”, currently consist of aerated lagoons and will be the focus of this facility plan. The West Milford WWTP operated under National Pollutant Discharge elimination 9be79a42ccc670be95b3fbe74c3e5186NPDES Permit Number WV0084301.
S & S Landfill is a solid waste landfill located in Harrison County, West Virginia. The Landfill discharges leachate directly into the District’s sanitary sewer collection system, and is identified as an industrial user (IU01) in Greater Harrison’s NPDES permit.
The proposed funding for the upgrades and improvements to the West Milford WWTP is $1,950,000 WVDEP CWSRF Loan and $400,000 WVDEP Green Debt Forgiveness.
Greater Harrison County Public Service District proposed to pursue a project which consists of the installation of Bio-Domes and Bird Balls in the existing polishing pond.
The District has been communicating with Wastewater compliance systems, Inc. (WCS), who has patented a product to be used in wastewater treatment plants, specifically lagoons, to improve the overall treatment process. This process is known as “Bio-Dome”.
The “Bio-Dome” treatment process consists of units or pods, which are placed on the bottom of a lagoon and completely submerged. The units use air that is pumped through them from the bottom to the top. The bio-media within the Bio-Domes is used to promote growth of biofilms, beneficial bacteria, and to reduce ammonia-nitrogen, BOD, and TSS in the wastewater.
The District has approached WCS and has participated in a seminar about the product, as well as a site visit with the Regional Supplier and a WCS representative. The District anticipates utilizing the Bio-Dome treatment units in the polishing cell to allow for additional nitrification to meet required effluent limits.
The District recognizes a few advantages of this type of treatment process. The units or pods can be installed while the treatment plant is still in use, and operation and maintenance costs are low.
Other than the low operation and maintenance costs, the units require a surge of air to clean the units every three to six months. The short surge is a negligible cost. After approximately seven to ten years, the units must be inspected to be sure there is no damage. With the low operation and maintenance cost, and relatively inexpensive solution to help improve nitrification, the installation of Bio-Dome technology at the Greater Harrison County PSD 0.60 MGD wastewater treatment plant is the preferred solution.
