CWCB approves dough for projects in the South Platte River Basin

From The Pueblo Chieftain (Chris Woodka):

The bull’s-eye for the state’s municipal water gap is centered over the Denver south metro area, which continues to boom in population.

Last week in Pueblo, the Colorado Water Conservation Board took a couple of actions that could keep that growth from sucking up water supplies from the rest of the state. The CWCB approved more than $100 million in loans to help water districts and some farmers in the area increase storage in Chatfield Reservoir and to expand a pipeline that will make their systems more efficient.

“There is a significant commitment to moving forward,” South Metro Water Authority Executive Director Eric Hecox told the CWCB Thursday. Representatives of various member districts filled the meeting room at the Pueblo Convention Center. The South Metro group includes 14 water districts that primarily rely on non-renewable Denver Basin groundwater to serve 300,000 people.

In a 2007 study, the group identified the Arkansas and Colorado river basins as areas where future pipelines might bring more water to the communities south of Denver. In recent years, other efforts to consolidate and boost resources have been identified, at least delaying more costly plans to import water.

One of those ways is a $145 million plan to add 20,600 acre-feet of storage accounts in Chatfield. The reallocation project to use the flood-control reservoir for supply storage has been in the works 20 years.

The CWCB approved $84 million in loans to the Centennial, Castle Pines and the Castle Pines North water and sanitation districts, as well as the Center of Colorado (Park County) and the Central Colorado (agricultural wells between Denver and Fort Morgan) water conservancy districts. For the urban users, the new accounts will allow greater ability to stretch existing supplies. For the agricultural users, it could mean turning on some of the wells that were shut off nearly a year ago.

The CWCB also approved $25 million to help four districts buy and expand the East Cherry Creek Valley Pipeline. Those districts are Cottonwood, Inverness, Parker and Pinery. The ECCV pipeline is a $147 million project to improve distribution for 10 districts in Douglas and Arapahoe counties, and is part of the Water Infrastructure and Supply Efficiency Project. That project also allows the districts to use excess capacity in Aurora’s Prairie Waters Project to capture and redistribute return flows from Denver water and Aurora.

One of the components also includes Parker Reservoir, which provides additional storage for some WISE participants.
