About this file
This set of documents includes construction plans and specifications for the St. Regis Arsenic Treatment System Project for the Lolo National Forest. The plans show the layout and details for demolishing an existing pump house and well system, and installing a new arsenic removal system using drywell leach fields. The system will connect to an existing well and treat water to remove arsenic above federal standards before discharging to the leach fields. Key project elements include demolishing the pump house and associated piping, installing a new arsenic filtration system in the pump house, connecting to the well, and constructing four 50-gallon drywells with associated piping in the leach field area. Relevant construction details and specifications are provided.
The related federal contract opportunity is a solicitation for the St. Regis Arsenic Treatment System Project issued by the USDA Forest Service Lolo National Forest. Interested contractors are instructed to carefully review all documents and attachments and submit any responses to the identified contracting officer via email.
