Phase 1B Pipeline – Alliance Regional Water Authority

Caldwell County Texas

Lockwood, Andrews & Newnam Inc. (LAN) was selected by the Alliance Regional Water Authority (Alliance Water), as a pipeline engineering consultant for a major water project serving several Texas communities in the I-35 corridor.

This project, the Phase 1B Program, will pump water from the Carrizo-Wilcox Aquifer in Caldwell County, and includes design and construction of a new treatment plant, well field, raw waterlines, 95 miles of 24- to 48-inch-diameter treated water pipelines, an operations and maintenance facility, and connection points to all the stakeholders.
