Betasso Water Treatment Facility Upgrade


The Betasso Water Treatment Facility is one of two drinking water treatment facilities that provide potable water for the City of Boulder. Betasso was originally constructed in 1964 as the city's primary potable water source. It currently supplies approximately 2/3 of the city's annual water use demand. The Betasso Water Treatment Facility Upgrade capital improvement project is a complex project that focuses on seven major process improvements. These improvements represent a combination of aging component replacement, and new and existing process improvements. 
These improvements include:
  • Pretreatment process upgrades;
  • Pretreatment process building addition;
  • Filtration upgrades;
  • Replacement of 20 large diameter filter control valves; 
  • Installation of a sludge dewatering system;
  • Electrical system upgrades; and 
  • Various on-site water tank repairs and recoating
