Stebbins, Alaska Water and Wastewater Infrastructure Construction Project

This opportunity involves the construction and operation of new water and wastewater infrastructure for the City of Stebbins, Alaska, overseen by the U.S. Army Corps of Engineers and the Alaska Department of Environmental Conservation. - Government Buyer: - U.S. Army Corps of Engineers (USACE) - Alaska Department of Environmental Conservation (ADEC) - Project Scope: - Construction of a new water intake structure with a submersible pump in a 12-inch HDPE casing, anchored 120 feet below the water surface - Installation of approximately 2,400 feet of new aboveground Raw Water Transmission Line (RWTL) and 6,450 feet of new RWTL on existing grade, with duckbill anchors every 20 feet - Construction of a 300-foot causeway across a pond, impacting 0.48 acres of wetlands - Upgrades to the water treatment plant and creation of a raw water impoundment - Installation of an 830-foot arctic sewer force main extension, buried 4 feet below ground and supported by helical piles - Upgrades and extension of the sewage lagoon access road (2,480 feet total) - Construction of a new three-cell sewage lagoon system (primary, secondary, and solids/honeybucket waste), covering approximately 12 acres - Products/Materials: - 12-inch HDPE casing for water intake - Class 1 riprap (65 cubic yards) and fill material (30 cubic yards) for intake protection - Geotextile fabric and embankment fill for road and lagoon construction - Services: - Site preparation, pipeline installation, lagoon construction, road upgrades, and environmental mitigation - Notable Requirements: - Permanent discharge of fill into approximately 8.74 acres of wetlands and waters - Aboveground pipeline installation and use of existing infrastructure to minimize wetland impacts - No compensatory mitigation required due to local wetland abundance - Project is essential for public health and environmental protection - No specific OEMs or commercial vendors are named; the focus is on civil construction and environmental compliance.

Description

The City of Stebbins proposes to construct and operate new water and wastewater systems to address sanitation deficiencies in the community. The project includes construction of a new water intake, raw water transmission line, sewer force main, sewage lagoon access road, and a new sewage lagoon system. The work involves permanent discharge of fill material into wetlands and other waters of the U.S. to build these facilities. The project aims to provide year-round access to potable water and sanitary wastewater disposal, addressing critical sanitation issues including failing septic systems and over-capacity honeybucket disposal sites. The total wetland impact is approximately 8.74 acres, with mitigation measures to avoid and minimize impacts where practicable.
