Sewer connection placard to reduce delays and expedite inspections
To reduce delays in sewer connections and to expedite inspections, we have implemented a connection placard program.
Effective March 1, 2018, all sewer and storm inspections will require a connection placard to be clearly visible and attached to the stakes that identify the capped end of each connection.
The connection placard must be completed by the installing contractor and all details must match those as installed.
The district plumbing inspector will compare the data on the connection placard against the sewer design data for conformity.
Placards that do not match the most current version of the sewer connection permit will be failed. The contractor can call 3-1-1 to speak with Sewer Design for resolution.

The inspection must be completed before any concrete or asphalt is poured, to check the forms and base.
