Side Sewer Inspections

See also: 

What Is It?

Our side sewer inspections are based on the work you are doing. At a minimum, you need to do the following before the inspector arrives:

  • Bed all newly installed pipe with 5/8 clear crushed gravel (also known as Type 22), with the pipe still visible and the pipe material stamp facing up.
  • Pressure test sanitary pipe more than 10-feet long and any storm drain pipe in the right-of-way. The test must be ready for the inspection (see Section V.Q of Director’s Rule 4-2011, Requirements for Design & Construction of Side Sewers).
  • Complete an as-built drawing of all newly installed pipe, even if the new pipe is in the same location as the old pipe.

We may inspect other parts of your side sewer work, depending on your project. For example, if your project is associated with a construction permit and includes “Green Stormwater Infrastructure (GSI),” such as rain gardens and permeable pavement, we also inspect these features.

When to Schedule

You need an inspection before you cover your side sewer pipe or add gravel or soil elements of the GSI requirements. These specifics can be pre-determined by your inspector.

After hours inspections. We do not inspect projects before 7:30 a.m. or after 4:30 p.m. on weekdays or anytime on Saturday, Sunday and holidays. However, we can inspect your work outside of our business hours in special circumstances such as a large project with site constraints or road closures which limit our time to inspect during our business hours. You need to ask us 72 hours in advance and we schedule your inspection when our inspectors are available. Call us at (206) 684-8950 or contact your site inspector.
