The partners will be responsible for all costs to permit, design, construct, and maintain NISP. A mixture of cash, bonds, and low-interest loans will finance the project, which is estimated at $426 million, or about $10,000 per acre-foot of water. It is an affordable option to meet future needs: an equivalent amount of Colorado-Big Thompson water is approximately $15,000 per acre-foot, and many communities in the Front Range are paying much more for new water supplies. In addition, project construction would be phased, allowing the NISP partners to pay for the project on an as-needed basis.
