Aqua Engineering provided irrigation system design review and construction conformance review services for 138 individual center pivot, solid set sprinkler, and/or drip irrigation systems in Central Washington. Most of the individual systems are within the USBR Columbia River Basin Reclamation area.

The design reviews verify that the vendor designs are prepared per the National Engineering Handbook and Washington NRCS Standard Construction Specifications. Construction conformance review includes verification of each system installation to ensure all systems are installed per NRCS standards per the approved vendor design.

Continued correspondence was a critical element in the review process. In addition to phone conversations with numerous vendors, producers, and NRCS representatives, the design team at Aqua Engineering made a total of 17 trips on-site to Washington.
