Technical Presentation Abstract:
Delivering safe, dependable drinking water to Englewood residents is a top priority for the City of Englewood. While Englewood’s treated water meets drinking water regulations, the source of our water can adversely affect the taste, odor and hardness from time to time. Englewood’s primary water supply is delivered through the City Ditch from Chatfield Reservoir to Englewood through a combination of buried pipeline, overhead flumes, and open channel ditch through parts of unincorporated Douglas and Arapahoe Counties and the City of Littleton before reaching Englewood’s Allen Water Treatment Plant (Allen WTP). City Ditch is one of Englewood’s most critical water infrastructure assets. Englewood is converting its remaining 2.5-miles of open channel sections between Chatfield Reservoir and the Allen WTP to buried pipe.
This presentation will review the numerous benefits to the City including water quality, improving the system reliability and safety, transforming this supply from seasonal operation to year-round, addressing water loss, reducing energy use, and reducing the need for additional capital projects.
The presentation will also review design and construction challenges and how proactive management provided an overall benefit to the City. This includes extensive stakeholder engagement, defined work areas and coordination with road and trail users, the challenge of gravity hydraulics and matching the existing piping, designing for current and future operational needs, permitting and agency coordination, management of limited available cover, stormwater coordination, aligning with seasonal ditch operations, value engineering, and use of existing easements and railroad coordination.
