OBJECTIVES OF THE PRELIMINARY ENGINEERING REPORT
The objective of the Preliminary Engineering Report (PER) is to provide the residents of the GWBPA with the necessary information to make informed decisions for future actions to potentially construct and maintain a wastewater collection and treatment system. This PER will establish a recommended course of action for providing adequate wastewater collection and treatment systems that will meet the needs of the planning area residents, protect the health and safety of the public, and protect water resource quality for the next 20 years and beyond. The PER will also provide recommendations for meeting the anticipated State and Federal regulations relating to wastewater collection, treatment and disposal for the foreseeable future. These recommendations are based on the assessment of the existing systems, projected population growth, and anticipated regulations.

Major tasks of the PER are summarized as follows:

1. Initial Planning: Compile and analyze planning data including:

• Service area definition,
• Population analysis and projections,
• Wastewater flow and wasteload forecasts.

2. Evaluate Planning Area Conditions: Evaluate the existing conditions within the planning area from a demographic and physical standpoint.

• Evaluation of the existing population and demographic characteristics of the planning areas,
• Evaluation of the existing water quality conditions in and around the planning area, including the effect of on-site wastewater treatment facilities on the quality of Flathead Lake water,
• Evaluation of the topography and other physical conditions of the site to determine reasonable collection system and treatment facility alternatives, and
• Summary of existing and possible future regulatory requirements affecting wastewater systems.

3. Develop and evaluate alternatives to:

• Construct a new sewer collection system and treatment facility,
• Meet planning area residents’ needs,
• Investigate and analyze opportunities to partner with other organizations near the planning area that already provide wastewater collection and treatment, and
• Meet regulatory agency requirements.

4. Develop implementation plan funding strategy: This task will result in a written plan with tools that can be use to make the necessary informed decisions to:

• Maintain service,
• Prevent or minimize conditions that would inhibit service,
• Meet anticipated demands, and
• Meet agency requirements.
