Southern Delievery System

The Southern Delivery System (SDS) Project is a proposed regional water delivery project designed to serve most or all of the Participants’ (City of Colorado Springs, City of Fountain, Security Water District and Pueblo West Metropolitan District) future water needs through 2046. As proposed, SDS would deliver Frying Pan-Arkansas (Fry-Ark) Project water and non-Fry-Ark Project water from the Arkansas River near the City of Pueblo to the Participants’ service areas.
The proposed SDS Project area would extend northward from the Arkansas River from a pipeline at Pueblo Reservoir to the City of Colorado Springs. As proposed, SDS would include construction and operation of the following components:

Use of 42,000 acre-feet (ac-ft) of existing storage capacity in Pueblo Reservoir on an as-available basis
Use of a Reclamation pipeline and outlet structure below Pueblo Dam to connect to an untreated (“raw”) water pipeline
2,200 feet of 78-inch pipeline capable of conveying 96 million gallons per day (mgd) and 1,100 feet of 72-inch pipeline capable of conveying 78 mgd of raw water
A 160-foot long, 36-inch diameter pipeline capable of conveying 18 mgd of raw water to the existing Pueblo West Pump Station
A 43-mile long, 66-inch diameter pipeline and three pump stations capable of conveying 78 mgd of raw water
A 30,500-ac-ft local terminal storage reservoir to store raw water
Relocation of electric transmission lines at the local terminal storage reservoir site
A water treatment plant, with capacity to treat up to 109 mgd of water, to provide potable water for municipal and industrial use
Transmission pipelines to convey potable water from the water treatment plant to local water distribution systems
A 28,500-ac-ft water exchange reservoir and an associated conveyance system to store and release Colorado Springs’ reusable return flows
Purpose and Need
The basic project purpose is to provide a safe, reliable and sustainable water supply for the Participants through the foreseeable future.
The Participants have three needs that SDS would fulfill:
To use developed and undeveloped water supplies to meet most or all projected future demands through 2046
To develop additional water storage, delivery, and treatment capacity to provide system redundancy
To perfect and deliver the Participants’ existing Arkansas River Basin water rights
Role of the Bureau of Reclamation (Reclamation)
Pueblo Reservoir and associated facilities are owned by the United States and operated by Reclamation. The use of these facilities by other entities for water storage or conveyance requires contracts with Reclamation. Execution of 40-year contracts for the use of Reclamation facilities is the major Federal action analyzed in this Environmental Impact Statement (EIS). Reclamation is the lead agency for the Federal action to be and is responsible for environmental evaluation and preparation of an EIS and a Record of Decision. The U.S. Army Corps of Engineers, Bureau of Land Management and U.S. Fish and Wildlife Service are cooperating agencies.
