General presentation to deliver basic septic system information to Minnesota homeowners.

1. Note to Reviewers: This Wastewater 101 Power Point presentation, much of which I developed, is what is typically used with community leaders and community members at an early meeting with a Small Community Wastewater Education Program (SCWEP) educator. The presentation is usually tailored to meet a community’s specific needs. In addition, I have attached another presentation, beginning with slide 67, that shows that the SCWEP is capable of delivering numerous in depth presentations on a variety of topics discussed in this presentation.

2. Overview of the Decentralized Approach, the Community Process, and Onsite Treatment Options

67. Note to Reviewers: The following, which I created, is a presentation geared toward the topic of choosing an appropriate community structure (if none exists). This is an example of a fleshed out topic that was mentioned in slide 26, but not discussed in detail, in the Wastewater 101 presentation. The SCWEP is capable of delivering numerous in depth presentations on a variety of topics mentioned in the Wastewater 101 presentation.
