The anticipated cost to build a controversial water-supply project in northern Colorado has increased 15% from 2006 estimates, to $490 million, project officials say. That total is up sharply from the original $350-million estimate at the project’s 2003 inception.
The Northern Colorado Water Conservancy is coordinating the Northern Integrated Supply Project, or NISP, for 11 funding cities and four water districts in Weld and Larimer counties. At completion, NISP will supply 40,000 acre-ft of water per year to area residents.
