Arkansas Valley Conduit

Overview

The Arkansas Valley Conduit (AVC) is a major infrastructure project that, upon completion, will provide reliable municipal and industrial water to 40 communities in Southeastern Colorado. The pipelines will bring water from Pueblo Reservoir to Bent, Crowley, Kiowa, Otero, Prowers, and Pueblo counties. It is projected to serve up to 50,000 people in the future (equivalent to 7,500 acre-feet per year).

Currently, many people in these areas rely on groundwater supplies that may be contaminated by naturally occurring radionuclides such as radium and uranium, or use surface water that contains harmful microorganisms and pollutants. Alternatives for these communities consist of expensive options such as reverse-osmosis, ion exchange, filtration, and bottled water. The region’s health and welfare depend on a reliable source of clean, safe water.

The Fryingpan-Arkansas Project Act, signed in 1962 by President John F. Kennedy, authorized construction of the AVC, but it was never constructed because the communities could not afford 100 percent of the costs. Public Law 111-11, signed by President Barack Obama in 2009, provided 65 percent federal funding for the Arkansas Valley Conduit. A preferred project design was identified in 2014 and has since been revised to reduce costs.

The U.S. Bureau of Reclamation worked with Project sponsors (the Southeastern Colorado Water Conservancy District) to reduce costs, the need for federal appropriations, and the time needed to construct the AVC.

Congress provided a $28 million appropriation in 2020 to move the Project into construction.

General

  • The AVC was authorized in the 1962 Fryingpan-Arkansas Project Act as a way to bring clean drinking water to communities east of Pueblo.
  • These communities rely on groundwater supplies that, in many cases, are contaminated with naturally occurring radionuclides, selenium, salts, nitrates and other harmful materials.
  • The AVC will provide a reliable long-term municipal and industrial water supply to communities east of Pueblo along the Arkansas River in southeastern Colorado.
  • The AVC will serve an estimated future population of 50,000.
  • The AVC, when completed, will deliver as much as 7,500 acre-feet of water annually through 103 miles of trunkline from Pueblo to Lamar. Water will flow by gravity, except for one pumping station to bring water to Eads.
  • The AVC is estimated to cost between $564 million and $610 million (2019 dollars). Funding will be through federal appropriations, federal loans and grants, state loans and grants, and miscellaneous revenues from the Fryingpan-Arkansas Project.
  • 35 percent of total Project costs will be repaid by local Project beneficiaries over a period of up to 50 years.
  • Reclamation awarded the inaugural contract of the AVC to construct the first Boone Reach trunk line section in September, 2022.

History

The Arkansas Valley Conduit (AVC) dates back more than six decades.

Cities and chambers of commerce in Southeastern Colorado began talking about a pipeline project in the 1950s as a way to deal with a chronically poor water supply in the Lower Arkansas Valley. The Arkansas River had been heavily appropriated for irrigated agriculture, and groundwater was brackish. The Water Development Association of Southern Colorado sold golden frying pans up and down the valley to promote the Fryingpan-Arkansas Project, which held the promise of bringing a supplemental supply of water for both irrigation and domestic use.

The Southeastern Colorado Water Conservancy District was formed in Pueblo District Court in 1958 as the local sponsor of the Fry-Ark Project. The District includes parts of nine counties, including six which are part of the AVC.

The AVC was authorized in the original Fry-Ark Project legislation in 1962 (Public Law 87-590). The AVC would not increase Fry-Ark Project water diversions from the western slope of Colorado; rather, it was intended to improve drinking water quality.

The AVC was not constructed with the original Fry-Ark Project primarily because of the beneficiaries’ inability to repay 100 percent of construction costs as identified to be required in the Public Law 87-590. In 2009, Congress amended the original Fry-Ark Project legislation in Public Law 111-11, which authorized annual federal funding, as necessary, for constructing the AVC, and provided that 35 percent of total Project construction costs would be repaid by local Project beneficiaries over a period of no more than 50 years.

The Bureau of Reclamation’s Technical Service Center (TSC) in Denver compared seven pipeline designs (six action alternatives plus no action) under the Final EIS. A Record of Decision (ROD) was signed by Reclamation’s Great Plains (now known as Missouri Basin) Regional Director in February 2014 which selected the “Comanche North Alterative” for implementation.

This alternative then became known as the “Preferred Alternative”. The TSC issued a Feasibility Design Report for the Preferred Alternative in September 2016 and a Project Cost Summary Report in October 2017. Total estimated cost to construct the preferred alternative was $640 million in 2016 dollars (approximately $700 million in 2019 dollars).

Through a collaborative effort between Reclamation and the Southeastern Colorado Water Conservancy District in 2018 and 2019, a revised Project configuration was developed with the goal of reducing the Project costs and requirements for Reclamation appropriations. Project estimated costs were reduced to a range of $564 to $610 million, and through alternative funding sources, the estimated requirement for additional Reclamation appropriations was reduced to a range of $355 to $414 million.
