Centennial: Good planning has the city ready to meet short-term supply needs

From the Highlands Ranch Herald (Chris Michlewicz):

Whether it was securing an agreement with the city of Englewood in 1980 to store 4,000 acre-feet of water in McLellan Reservoir or the recent discovery of a mutual benefit in loaning out some underused infrastructure to Castle Pines, the Centennial Water and Sanitation District has gradually tightened its grasp on what will only become a hotter commodity as the years pass…

Years of planning and a decision to shift from its reliance on groundwater from the Denver Basin, Denver-Arapahoe and Laramie-Fox Hills aquifers have put Centennial Water on a track that is much different than other providers in the region. But because the district is not openly touting its fortunate position, it is sometimes lumped in with other districts. Incorrect information and rumors have given some customers a wrong impression. Hendrick says it drives him nuts to hear that some believe Highlands Ranch is entirely on groundwater. “Nothing could be further from the truth,” said Sherry Eppers, community relations manager for the district.

Between McLellan and the South Platte Reservoir, there is 10,000 acre-feet of raw water storage capacity exclusively for Highlands Ranch users. Centennial Water also helped build a 400-acre-foot reservoir in Park County that has been in operation for two years. Surface water rights for Plum Creek came with the initial purchase of the ranch in 1979, but leaders have been actively seeking and developing other sources for several years…

Centennial Water continues to become involved in new endeavors, including the reallocation project that could nearly double the capacity at Chatfield Reservoir within a few years.
The district, which is part of the South Metro Water Supply Authority, is also a potential participant in the WISE program, which if approved will funnel 100,000 acre-feet of reclaimed water from Denver and Aurora to the south metro suburbs over a 10-year period…

Centennial Water wants to continue reducing its groundwater use; it takes 10 percent of the groundwater it’s entitled to, and has used only surface water over the last four years because of wetter seasons. It has even replenished some of the water it has removed from the aquifers over the years. “We’ve recharged 14,000 acre-feet over the last 20 years,” Hendrick said. “That has reduced the drain on the aquifers.”
