STATEMENT OF WORK FOR

MCC Electrical Panels and Rail

Mount Meter and Remote Display

INTRODUCTION

The Yuma Area Office (YAO) within the Bureau of Reclamation (Reclamation) currently operates four high-capacity production well systems in the Yuma area. The well fields have been established under various congressional acts to control groundwater levels and meet contractual obligations with various water districts for draining the Association Lands, provide return flows for delivery and water to Mexico to meet treaty obligations, and to provide return flow credits for the various water districts. In order to meet current and future commitments, new and replacement wells will be needed on a regular basis.

Reclamation needs the flexibility to have new and replacement wells designed and drilled using current industry standards and meeting Arizona State Requirements.

PROJECT OBJECTIVE

The objective of this purchase requisition is to receive and install materials to establish new wells to produce an additional 25,000-acre feet of low-salinity water that will be conveyed North to the Colorado River and delivered to Mexico, thereby conserving like amounts in Lake Mead.

The 25,000 AF is in addition to the 25,000 AF that is to be produced by the 242 Wellfield.
