Berlin Lake Sewer Treatment Plant ReplacementBerlin Lake, Berlin Center, PennsylvaniaThe U.S. Army Corps of Engineers (USACE), Pittsburgh District, is carrying out a Project to replace the existing Wastewater Treatment Facility (WWTF) at the location referenced above. Work is to be performed entirely on Government property, and the WWTP services USACE campgrounds and two field offices. The campground is open annually from mid-May to mid-September, while the two USACE field offices are open year-round. The Government currently operates the existing 30,000 gallon per day (gpd) WWTF year-round and will need continuous access and utility services during the Project. The new WWTF is to be constructed adjacent to the existing WWTF. Final switch over to the new WWTF and operation of the new WWTF in compliance with approved permits is required prior to demolition of the existing WWTF.Major features and coordination efforts of the Project generally include, but are not limited to, the following:a. Installing a new, prefabricated pump station and force main line.b. Installing a new, prefabricated WWTF with appurtenances. The WWTF (rated at 30,000 gpd) will utilize the extended aeration process and may have, among other features, a trash trap, flow equalization/aeration/clarifier/sludge holding/dosing tanks, fixed media and surface sand filtration, and UV disinfection.c. Renovating the existing WWTF control/laboratory building.d. Limited testing has been conducted and it is assumed that additional lead and asbestos testing/remediation may be required.e. Upgrading the existing power supply per local utility requirements and installation of a dedicated automatic emergency power generator.f. Installing gravel driveway for access and parking, lighting, and security fencing/gates.g. Reconfiguring portions of the existing sanitary sewer piping near the headworks and outfall manhole of the existing WWTF to accommodate the new hydraulic profile.h. Site grading, including best management practices (BMPs) for erosion and sediment control, along with final restoration and landscaping with Ohio native plant species.i. An Ohio Environmental Protection Agency (OPEA) Permit-to-Install (PTI) permit has been secured by the Government for the new WWTF and the contractor will have to comply with any OEPA requirements.j. Seamless switchover from the existing WWTF to the new WWTF.k. Demolition and proper disposal of the existing WWTF and appurtenances.l. OEPA-licensed-operator startup and operation of the new WWTF for a limited duration, including training of the Government or other operators.The submittal/fabrication process is planned to start in 2025, with physical construction and restoration estimated to take place from October 2025 through October 2026. Closeout is expected to be complete before the end of 2026. Campground usage and operations throughout the year are assumed to remain unchanged.Disposal of construction waste material will be disposed of at commercially pe…
