Davis Surface Water Supply Pipelines Project

The Davis Surface Water Pipelines Project distributes surface water supplied by the Woodland Davis Clean Water Agency Regional Water Treatment Facility to the City of Davis through a pipeline connection at the northern city limits. The project consisted of over 35,000 lineal feet of new 12 to 30-inch diameter water pipeline constructed predominantly within existing roadways, including trenchless pipeline crossings at the I-80/UPRR tracks, Highway 113, the UPRR tracks at Covell Boulevard, and at a drainage canal crossing.

 

Within an aggressive schedule, Blackburn completed a subsurface investigation (27 exploratory borings), laboratory testing, engineering analysis, and preparation of a geotechnical report. Our report included recommendations for pipeline trench construction, stability, and backfill, recommendations for replacement pavement, and design and construction considerations for the proposed trenchless crossings. Blackburn also prepared a separate geotechnical report for the UC Davis transmission mains that connect to the city’s new pipelines.
