Connection to Existing Sewer – Maintain Sewage Flow
1. Existing Sewer Pipe2. Add Manhole Base
& Shaft

Manhole Connections or Rehab Work
![Page 10: PRESENTATION FOR CWEA TRAINING Keys to Successful Pipeline/Infrastructure Projects](https://reader037.vdocument.in/reader037/viewer/2022102908/56812b73550346895d8f93bb/html5/thumbnails/10.jpg)
Key Issues:• MH Access (cover size)• Confined Space Entry• Sizing of Flow-thru Tubes• Confirmation of Back-up
Manhole Connections or Rehab Work

Key: No Sewer Spills
Rehabilitation – Bypass Pumping
![Page 14: PRESENTATION FOR CWEA TRAINING Keys to Successful Pipeline/Infrastructure Projects](https://reader037.vdocument.in/reader037/viewer/2022102908/56812b73550346895d8f93bb/html5/thumbnails/14.jpg)
• Bypass Pumps• Bypass Piping• Redundancy• Spill Prevention &
Response Plan• Noise Monitoring• Odor Monitoring• Monitoring Systems
Key Elements of Bypass Plan

• Capacity – Typical Sewage Flow & Peak Flow Rate
• Suction Supply• Pumping Equipment
(submersible, self-priming centrifugal)
• Valving
Bypass Pumps
