1. What is the Recycled Water Use Exhibit Design Guide?

The Recycled Water Use Exhibit (RWU Exhibit) is to provide a simplified plan of the irrigation system to identify pertinent site, irrigation, and civil improvement information to aid the plan review by District staff as well as State Department of Drinking Water and the Orange County Department of Environmental Health.  All submitted recycled water irrigation plans must include the RWU Exhibit as part of the submitted plan set.

2. How do I submit Irrigation Plans for Recycled Water?

All on-site irrigation systems that use or plan to use recycled water must be reviewed and approved by the District’s Chief Engineer to ensure the project complies with the District’s Technical Requirements for Recycled Water Service.  Please consult the recycled water irrigation plan review and approval flowchart.  A review and inspection fee of 4% is required.  The following documents need to be submitted:

• Irrigation Plans
• Recycled Water Use (RWU) Exhibit that conforms to District's RWU Design Guide
• Estimated cost of irrigation system
• District approved Civil Engineering sheet that provides location of recycled water point of connection(s).

3. What is the review and inspection fee for Recycled Water Irrigation Plans?

At the time of plans are submitted to the District, the applicant shall make a nonrefundable plan review fee deposit based on 2.0 percent of the estimated construction cost of the recycled irrigation facilities. A minimum deposit of $200 will be required on all projects. Prior to approval of the irrigation plans by the District, the applicant shall pay the final plan review and inspection fee, which will be based on 4.0 percent of the estimated construction cost of the system. The estimated cost will be prepared by the applicant and submitted for review by the District. The minimum fee shall be $400. The applicant will be given credit for the plan review fee deposit. The percentage and/or minimum fee may be revised by the District without prior notice to the applicant. Fees shall be paid prior to the approval of plans.
