INTRODUCTION Flathead County received a Renewable Resources Grant from the Montana Department of Natural Resources and Conservation (DNRC) to fund the efforts of the Flathead Regional Wastewater Management Group (FRWMG). The FRWMG advertised for a Statement of Qualifications from consulting engineers and through this process, Carver Engineering was selected as the County’s Consultant. In general, the services provided to the Group have included the preparation of this report and GIS mapping that covers the Flathead Lake and Stillwater River watersheds (See Figure IN-1 at the end of this section) and identifies existing public wastewater collection and treatment systems and existing on-site septic systems within the watersheds. The following report and mapping efforts prepared by Carver Engineering will fulfill the requirements of the DNRC Renewable Resources grant. The specific scope of services agreed upon by Carver Engineering and the FRWMG included the following services for this report and GIS mapping: Review existing studies, plans, reports and maps written or obtained by FRWMG and/or produced by others relating to wastewater collection, treatment and disposal capacity and planning of the existing public wastewater facilities in the study area. Contact the owners/operators of the existing major wastewater facilities within the watershed to obtain collection system drawings, determine capacities and limitations of the collection and treatment systems, determine existing and projected wastewater flows, influent and effluent quality and obtain, where available, facility planning studies for the wastewater systems. Using available information, analyze the conveyance and treatment capacities of existing major wastewater facilities in the study area and compare with existing and projected flows from the service area to determine if sufficient excess capacity is available to serve additional areas outside of the current service area. Identify unsewered areas outside of the current established service areas of the existing major wastewater facilities that could be served by public wastewater systems. Develop estimates of general costs of collection system improvements into currently unsewered areas including gravity sewer main extensions, public sewage pumping stations, individual grinder pump stations, pressure mains, and sewer service lines. Prepare a map of the sewer service areas of the existing major wastewater facilities in the watershed. Prepare a map showing location of existing on-site septic systems within the watershed and classify the age of these existing systems. (Hours allotted are based upon using GIS information already entered into existing mapping systems of Flathead and Lake Counties. Time is not allotted for developing database for any existing septic systems not presently entered in mapping systems.) Sewage Treatment in the Flathead Basin 1
