The materials presented review the range of possible solutions that the Sewer System Master Plan Team evaluated to address the identified collection system and treatment facilities challenges. From this wide range of options, the suite of feasible approaches that are consistent with a dense urban environment are included in the team recommendations. These recommendations form the background or baseline projects for the implementation through the Sewer System Improvement Program.
The materials that are provided include:
- Summary Report Chapter 5 [PDF] on Implementation.
- Further detail in the Supplementary Report Chapter 5 [PDF] that contains an expanded discussion and details about the alternative considered.
- Seventeen Technical Memoranda that include the Long-Term Biosolids Management Plan, Odor Control options for both the Collection System and Treatment Facilities, and a range of memoranda on sustainability considerations including Greenhouse Gas Analysis, Low Impact Design/Development, and Recycled Water.
