E3 served as the Independent Engineer for the Vista Ridge Regional Supply Project (Project), a 142-mile water pipeline that will expand the water supply by 20 percent for the fast-growing City of San Antonio, Texas. The Project is one of the largest-scale public-private partnerships (P3) in the water sector. Missouri-based Garney Holding Company (dba Garney Construction), through its subsidiaries, led the Project development team and will complete the design and construction of the Project. The Project company entered into a 30-year concession agreement with the City of San Antonio, acting through San Antonio Water System, to deliver 16.3 billion gallons of water to the City annually. Project financing for the $927 million non-recourse loan was arranged through Sumitomo Mitsui Banking Corporation, who led an international bank group that included CoBank, Commonwealth Bank of Australia, ING, Korean Development Bank, and Societe Generale. As the Independent Engineer, the E3 team provided technical due diligence, addressing the technical and commercial aspects of the Project on behalf of the financing parties.
