Seattle Public Utilities (SPU) has updated their Core Tap Procedures for Storm and Sewer Mains web page to make it easier to understand. SPU also made updates to match their current practice for installing tees in a variety of pipe materials.
Some specific changes include:
- A new table in section 4.5 that outlines the bedding materials required to restore support to the main at the core tap locations
- New sections, such as:
- Non-Standard Connections Process
- Non-Standard Connections That SPU May Approve
- Abandoning a Sewer Lateral at the Mainline
