The Problem
The Malden Public Service District’s wastewater treatment plant was originally constructed in 1980 and provides service to approximately 3,600 customers. Due to its age, the treatment plant had reached the end of its useful life in terms of both hydraulic capacity and treatment technology and was suffering severe inflow and infiltration problems. Additionally, the plant was not in compliance with a West Virginia Department of Environmental Protection Consent Decree, as it discharged some of its flow directly into Campbells Creek.
After being selected to work on the project, the experienced Utilities Engineering professionals at Thrasher were able to identify solutions that were best suited for the Malden Public Service District Wastewater Treatment Plant and the area residents.
The Solution
Thrasher provided engineering and construction services for Malden Public Service District’s wastewater project. The team prepared a Facility Plan and evaluated three treatment options to meet Consent Decree requirements. To modernize the plant and ensure compliance, Thrasher guided Malden through a series of strategic upgrades.
The result is a state-of-the-art, operator-friendly facility. It treats a wide range of flows while meeting NPDES permit limits. To meet WVDEP’s Consent Decree, Thrasher upgraded the 38-year-old plant to a VLR treatment process with a SmartBNR control system for optimal efficiency. The improvements eliminated a permitted raw sewage overflow, boosted hydraulic capacity, and reduced inflow and infiltration in the collection system.
These upgrades created a functional, sustainable system with lasting environmental benefits. The project earned first place in its category at the ACEC Engineering Excellence Awards and was invited to compete nationally.
