Project Announcement: City of Austin’s Pilot Knob Water Line Project

May 18, 2026

HVJ is proud to announce that we have teamed up with Jacobs to provide critical geotechnical investigation services for the City of Austin’s Pilot Knob Water Line Project. This massive infrastructure initiative involves engineering, permitting, and construction of approximately 76,000 linear feet of a 66-inch-diameter water transmission main,  extending from existing infrastructure north of Lady Bird Lake to the proposed Pilot Knob Reservoir and Pump Station site. The project scope is technically comprehensive, encompassing large-diameter pipeline installation, complex roadway and waterway crossings, system control appurtenances, and robust corrosion protection measures to ensure long-term durability.

Beyond the technical specifications, the Pilot Knob Water Line Project serves as a vital backbone for the region’s future, designed to enhance water system reliability and operational flexibility. By significantly increasing transmission capacity and resiliency, the new infrastructure will facilitate improved water delivery to essential reservoir and pump station facilities. Ultimately, this investment supports the sustained residential, commercial, and industrial growth of the City of Austin’s service area, ensuring that the community's water needs are met as it continues to expand.

As the geotechnical lead for this phase, HVJ is dedicated to providing the precise data and analysis required to navigate Austin's unique terrain. Our work ensures that this 14-mile stretch of infrastructure is built on a foundation of safety and engineering excellence.
