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 PSD and the area residents.
The Solution
Thrasher was selected to provide engineering and construction services for Malden’s project, preparing a Facility Plan and evaluating three treatment alternatives that would meet the Consent Decree requirements. To make the plant a modern, effective, compliant facility, the team at Thrasher led Malden PSD through a series of changes.
As a result, the Malden Public Service District Wastewater Treatment Plant is a state-of-the-art, operator-friendly facility capable of treating a wide range of wastewater flows while meeting effluent limits required by their NPDES discharge permit. To achieve all of the objectives required by the Consent Decree issued by the WVDEP, the 38-year-old wastewater plant was upgraded to a VLR treatment process featuring a SmartBNR control system for optimum operation efficiency. The upgrade included eliminating a permitted raw sewage overflow, increasing the hydraulic capacity, and reducing inflow and infiltration within the existing collection system. The work done on this project not only made for a beautiful, functional water treatment system, but it has a sustainable positive impact on the environment in the area.
This project was awarded first place in its category at the American Council of Engineering Companies’ Engineering Excellence Awards and was invited to submit to the national award competition.
