A Colorado water court approved the Platte Valley Water Partnership project on October 15, 2026, enabling construction of a 125-mile pipeline and reservoir. This $1.1 billion initiative aims to provide 22,000 acre-feet of water each for farm and urban sectors.
Why it matters
The project serves as a model to balance water supplies between cities and rural economies while explicitly prohibiting the practice of drying up farmland to acquire resources. It addresses regional water security amidst a broader trend where Colorado has lost over 30% of its irrigated agricultural land in three decades.
The partnership includes significant cost shares from the Parker Water and Sanitation District at 52%, the Lower South Platte Water Conservancy District at 27%, and Castle Rock at 20%. The infrastructure is designed to divert water during storm events and floods.
The players
Parker Water and Sanitation District
This district serves as the primary financial backer for the partnership with a 52% cost share.
Lower South Platte Water Conservancy District
Based in Sterling, this district manages water interests in the region and holds a 27% stake in the project.
Castle Rock
This municipality is a key participant in the water partnership, contributing 20% of the project funding.
The details
The project relies on a 2019 water right and utilizes a 125-mile pipeline to distribute water. It specifically mandates that no water can be delivered if it was acquired by retiring active farm fields.
Timeline
2013: Major flood occurred allowing for potential water diversion.
2019: The project's water right was established.
2021: The Platte Valley Water Partnership was officially launched.
2023: A major flood occurred allowing for potential water diversion.
October 15, 2026: The water court approved the project.
Market Landscape
This pipeline development signals a shift in Colorado water management by prioritizing dual-use infrastructure over traditional agricultural divestment. It positions the participant districts to secure long-term water independence against a backdrop of shrinking state agricultural land.
The project aims to protect the local agricultural economy from the common practice of land retirement for water rights. Residents in participating urban districts can expect a more secure water supply as the partnership moves into the construction phase.
The takeaway
This approval represents a strategic shift toward infrastructure-based water sharing between cities and farms. By focusing on flood-based diversions, the project attempts to maintain agricultural productivity while meeting growing urban demands.
What happens next
Construction of the project's first phase, intended to begin water delivery for local farmers, is anticipated within five to seven years. Full completion of the infrastructure is slated for 2040.
