Irrigation System Inspections

Two inspections are required to complete the installation of the recycled water irrigation system on each dual-plumbed home lot.Open Trench Inspection

1. The open-trench inspection is conducted first and requires that all purple pipes or copper fill lines for water features, shall be left completely exposed in the trenches. Contractors or homeowners do not have to be present for the open-trench inspection. An EID inspector will leave an inspection form at the home when each inspection is completed.

2. The final inspection is conducted when the irrigation system is completed and the landscape is installed. The contractor or homeowner is required to be present during the final inspection for system testing and any required adjustments.


Drinking Water Pipe Inspections

1.  All drinking water lines that extend underground from the house for water features, pools, sinks, etc., are required to be constructed of copper.  An approved plan and an open trench inspection are required for these installations. 

2.  All dual-plumbed homes are required to have the drinking water line from the meter to the home inspected by EID.

All inspections shall be scheduled through the EID recycled water request line: (530) 295-6873. Allow 48 hours for inspection.
