The Town of Telluride owns and operates several water treatment facilities to provide drinking water for the
service area. The Pandora Water Treatment Plant (WTP) and the Mill Creek WTP are the primary water
treatment facilities in operation. Each plant provides roughly 50% of the demand during peak season.
The Mill Creek WTP was originally constructed in 1987 as a conventional filtration plant. The 1.0 MGD facility
contains two parallel treatment trains which at one time consisted of flocculation tanks and up flow tube settlers
in sedimentation tanks. The multimedia filters were taken out of service to accommodate ultra-filtration
membranes installed downstream of the flocculation/sedimentation process. Both granular media filters were
removed. The ultra-filtration membranes are currently on the last of their life cycle and must be replaced (to
include the headers and stands). A hot water wash clean-in-place is also needed.
Mill Creek WTP needs a new filter/membrane and clean-in-place system commissioned and implemented to
include system and process integration within the existing footprint. Existing raw water data can be requested.
Project includes raw water quality analysis for chemical additions needed for new filters before installation of
equipment. Water production will be maintained at 1MGD. Teams may be contractor, engineer, or vendor lead.
Project team is expected to help with any CDPHE requirements and documentation. February 9, 2022 Optional Pre-Proposal Site Visit
