I. INTRODUCTION

The Northern Colorado Water Conservancy District and the Municipal Subdistrict, Northern Colorado Water Conservancy District (collectively referred to as “Northern Water”) are requesting proposals from qualified Respondents for On-Call Miscellaneous Concrete Services, on an as-needed basis to support the maintenance, repair, and construction of concrete infrastructure throughout Northern Water service areas.

Northern Water manages a complex network of water delivery infrastructure, including canals, ditches, control structures, access roads, facilities, and related appurtenances that periodically require concrete work to maintain structural integrity, operational functionality, and safety compliance. This solicitation establishes a pool of qualified Respondents capable of responding to routine, urgent, and emergency concrete needs in a timely and professional manner.

II. NORTHERN WATER BACKGROUND

Northern Water is headquartered in Berthoud, Colorado (approximately 40 miles north of Denver) and has more than 195 full-time staff members engaged in the operations, engineering, environmental, financial, and administrative functions of the Northern Colorado Water Conservancy District and the Municipal Subdistrict. Most staff work out of Northern Water’s headquarters in Berthoud with some out of Northern Water’s Willow Creek campus in Granby, Colorado.

II.1 NORTHERN COLORADO WATER CONSERVANCY DISTRICT

The Northern Colorado Water Conservancy District (Northern Water) is a political subdivision and a quasi-municipal corporation of the state of Colorado created by decree of the District Court of Weld County, Colorado, on September 20, 1937, pursuant to the Water Conservancy Act. The Water Conservancy Act empowers Northern Water, or any duly created subdistrict to acquire water; to obtain rights-of-way for certain water works; to contract with the United States or otherwise; to provide for construction of water facilities; to assume contractual or bonded indebtedness; to administer, operate, and maintain physical works; to conserve, control, allocate, and distribute water supplies for supplemental use; and to derive the revenues needed to accomplish its purposes.

As authorized under the Water Conservancy Act, Northern Water has created four water activity enterprises:

• Southern Water Supply Project (SWSP) Water Activity Enterprise

• Pleasant Valley Pipeline (PVP) Water Activity Enterprise

• Northern Integrated Supply Project (NISP) Water Activity Enterprise https://www.northernwater.org/deliver-water/canals-pipelines-and-outlets/southern-water-supply-project https://www.northernwater.org/deliver-water/canals-pipelines-and-outlets/pleasant-valley-pipeline https://www.northernwater.org/deliver-water/plan-for-the-future/northern-integrated-supply-project

• Hydropower Water Activity Enterprise

Northern Water was created to contract with the U.S. Bureau of Reclamation (Reclamation) to build the Colorado-Big Thompson Project (C-BT Project). The C-BT Project provides supplemental water to irrigate more than 615,000 acres of farm and ranch land and nearly 1.1 million people in eight Northeastern Colorado counties. Northern Water also engages in water management and planning activities for the purpose of meeting present and future water supply needs of water users within its boundaries.

The majority of C-BT Project water comes from mountain snowmelt in the upper Colorado River basin west of the Continental Divide. Northern Water delivers on average 210,000 acre-feet of untreated water each year to the South Platte River Basin. The C-BT Project was constructed and is mostly owned by the United States through Reclamation. Northern Water owns the portions of the C-BT Project downstream of Horsetooth Reservoir and Carter Lake. Northern Water and Reclamation jointly operate and maintain the C-BT Project.

II.2 MUNICIPAL SUBDISTRICT

The Municipal Subdistrict, Northern Colorado Water Conservancy District (Subdistrict) is a separate political subdivision and quasi municipal corporation of the State and was created by decree of the District Court of Weld County, Colorado on July 6, 1970. It was organized in 1970 for the principal purpose of developing a water supply for use by six (6) Front Range communities. Today the Subdistrict provides a water supply to 17 public entities.

As authorized under the Water Conservancy Act, the Subdistrict has created two water activity enterprises:

• Windy Gap Project Water Activity Enterprise

• Windy Gap Firming Project Water Activity Enterprise

Today the organization continues on its early mission of collecting water west of the Continental Divide and delivering it to Northeastern Colorado for agricultural, municipal, domestic, industrial, and environmental uses. In addition to the current and future projects driving day-to-day operations, Northern Water also provides regional leadership through water efficiency programs, data collection and delivery, source water protection, and interagency cooperation.
