Castle Rock has developed a water supply system that can use renewable sources to meet the town’s growing demand. Burns & McDonnell developed a unique drinking water plant that treats both groundwater and surface water sources and helps the town add advanced treatment systems to the plant. The design firm provided piloting, design and onsite construction oversight services, collaborating with the contractor and owner from design through construction and start-up.

现在，Plum Creek设施可以净化多个原始水源，以符合饮用水标准，包括可再生的间接用水和直接修复水。

The project added several features to the operational drinking water plant, including a raw water blending step, biological filtration, advanced oxidation, granular activated carbon, ultraviolet disinfection and residuals handling. The new advanced treatment processes also reduce contaminants of emerging concern such as pharmaceuticals and personal care products, which conventional pretreatment and treatment technologies do not remove, while supporting the removal of giardia, viruses and cryptosporidium beyond regulatory requirements.

Because there is currently no regulatory framework for direct potable reuse treatment in Colorado, the project team collaborated with the Colorado Dept. of Public Health and Environment to invest in an advanced treatment train that is anticipated to go above and beyond requirements for future reuse treatment.
