Boulder using new ultraviolet light technology to safely treat wastewater
The new ultraviolet (UV) light disinfection system will replace the existing chlorine gas and sulfur dioxide gas systems, which have been in use since 1990 and pose a significant safety risk. The new technology is more efficient and eliminates the need to store and use hazardous gases. The UV light is a highly effective disinfectant for bacteria, viruses and protozoa.
“The new UV disinfection system is a major milestone for the facility and demonstrates the city’s commitment to continuous operational improvements that meet evolving community and regulatory needs,” said Director of Public Works for Utilities Jeff Arthur.
The Wastewater Treatment Facility improvements also include mechanical and electrical upgrades to the wastewater digester complex and headworks facility. The improvements are funded by a $9.2 million revenue bond and are expected to reduce long-term operating costs. Construction began in July 2011 and is currently on schedule to be completed in March 2013.
Wastewater from the community’s sanitary sewer systems is collected at the Wastewater Treatment Facility, where it is sent through a 20-hour, multi-stage treatment process. The facility treats an average of 12.5 million gallons of wastewater per day. In September 2012, the city’s Wastewater Treatment Facility received a Plant Performance Award from the Rocky Mountain Water Environment Association (RMWEA) in recognition of the facility’s commitment to outstanding maintenance, operations and public relations.
